NAICS code 334419 identifies “Other Electronic Component Manufacturing” companies in North America — about 1,665 active U.S. firms — and buyers can reverse-search it on SAM.gov and D&B to build verified semiconductor distributor lists. This guide shows the filters, the 334413 pitfall, and the product codes that complete the picture.

What Is NAICS Code 334419 and What Does It Cover?

Most buyers meet NAICS codes only on government forms, yet the classification doubles as a free supplier-discovery tool when read from the purchasing side.

NAICS 334419 is the U.S. Census Bureau category for “Other Electronic Component Manufacturing” — a catch-all for component makers outside the semiconductor, capacitor, and connector codes.

Per the official NAICS definition from the U.S. Census Bureau (and IBISWorld’s summary), illustrative 334419 examples include crystals, electron tubes, LCD screens, microwave components, piezoelectric devices, PCB laminates, electronic switches, and transducers. The code sits inside the 3344 family alongside 334412 (bare PCBs), 334413 (semiconductors), 334416/334417 (capacitors and resistors), and 334418 (circuit assemblies).

Here is the practical implication. As a residual category, its pool is diverse: component factories, specialty assemblers, and distributors that register a manufacturing-adjacent code. That diversity is noise for statisticians but signal for sourcing teams — a 334419 filter surfaces smaller North American suppliers that never appear on franchised line cards. Our multi-channel sourcing playbook shows where such suppliers fit in a channel mix.

Does NAICS 334419 Include Semiconductor Manufacturers?

This is the most common misread of the code, and it sends many first-time searches in the wrong direction.

No. Semiconductor and related device manufacturing is NAICS 334413, a separate code. Code 334419 also excludes capacitors (334416), resistors (334417), and bare printed circuit boards (334412).

That is where most buyers get it wrong. They search 334419 expecting Intel-class chipmakers, find crystal oscillator plants and switch makers, then abandon the code. The better reading: 334419 companies are frequently adjacent to the semiconductor supply chain. Distributors, rep firms with value-added assembly, and obsolete-part specialists often register here because no dedicated “semiconductor distribution” NAICS code exists; wholesale codes (4236xx) describe their trade, but many entities pick 334419 at registration.

For an OEM or EMS buyer, the fix is a two-code search: 334413 for semiconductor sources, 334419 for the broader component and supplier ecosystem. The table maps the boundaries.

NAICS Code	Title	Covers	SBA Size Standard
334413	Semiconductor and Related Device Mfg.	ICs, diodes, transistors, wafers	1,250 employees
334414	Electronic Capacitor Mfg.	Fixed/variable capacitors	550 employees
334417	Electronic Connector Mfg.	Connectors, sockets	600 employees
334419	Other Electronic Component Mfg.	Crystals, tubes, LCDs, switches, transducers	750 employees

When you compare distributor types later, our vendor comparison framework provides the scoring template.

How Many Companies Fall Under NAICS 334419 in North America?

List size decides whether a code-based search is a shortcut or a swamp, so anchor the effort in real counts first.

About 1,665 active U.S. establishments classify under NAICS 334419, employing roughly 52,326 people, per siccode.com. The broader NAICS 3344 group represents a TAM near $500 billion with a 6.5% CAGR, per grata.com.

Two more numbers frame the opportunity. Samsearch.co tracks about 8,487 active opportunities — federal, state, local, and forecast — touching 334419, including NOAA X14 frequency multipliers and NSWC Crane brand-name security elements. D&B’s directory shows the filter works globally: a NAICS 3344 search isolates, for example, 361 electronics firms in the Philippines; the same logic applies to U.S. states.

Why does this matter? Because 1,665 companies is a workable universe. Filtered by state, headcount, and registration status, it collapses to a few hundred candidates — a list one analyst can qualify in weeks. For EMS firms rebuilding regional supply bases, that turns “reshoring” from a slogan into a spreadsheet. The SupplyICs industry solutions pages show how we segment these suppliers by end market.

How Do You Use SAM.gov to Find 334419 Registered Suppliers?

SAM.gov is built for sellers chasing contracts, but its Entity Search works equally well in reverse for buyers building supplier lists.

Run a SAM.gov Entity Search filtered by NAICS 334419 and status “Active.” Export candidates with their UEI, then verify exclusions, representations and certifications, and small-business designation before outreach.

The step-by-step: (1) open SAM.gov entity registration search; (2) filter by NAICS 334419; (3) add location filters to prioritize North American supply; (4) pull each candidate’s UEI record and check “Exclusions” — any debarment is an instant reject; (5) review Reps & Certs for quality claims and business type. Entities holding active SAM registrations have passed a baseline of federal vetting, which is why this screen beats a raw web directory.

Here is the catch. SAM registration proves administrative legitimacy, not product quality or stock depth. A 334419-registered entity may still be a two-person broker with no inspection lab. Treat SAM.gov as the top of the funnel: it answers “is this company real, U.S.-based, and not debarred?” The quality question comes next. Our supplier qualification audit framework picks up where SAM.gov stops.

How Do You Verify Supplier Credentials with Dun & Bradstreet?

A SAM.gov record tells you a supplier exists; it says nothing about whether that supplier survives until your 40-week order ships.

Dun & Bradstreet adds the financial layer: D-U-N-S identity resolution, credit and PAYDEX scores, corporate family trees, and NAICS-filtered directory search — the second screen after SAM.gov.

The workflow is complementary. SAM.gov confirms registration and exclusions; D&B confirms solvency and structure. A distributor with a clean SAM record but a deteriorating PAYDEX score and three recent restructurings is a line-down risk in slow motion — you find that in D&B, not SAM. D&B’s directory also re-runs the NAICS 3344 filter with revenue and headcount bands, separating a $5 million specialist from a $500 million broadline distributor.

Verification Channel	What It Proves	Data Depth	Cost
SAM.gov Entity Search	Registration, UEI, exclusions	Administrative	Free
D&B Directory / Credit	Solvency, family tree, PAYDEX	Financial	Subscription
FSC 5961/5962 filters	Product-level capability	Technical	Free (govt sources)
ISO 9001 / AS6081 certs	Quality system	Compliance	Audit effort

Here is the practical implication for OEM buyers: run the two free screens first, pay for D&B only on shortlisted candidates, and reserve on-site audits for approved-vendor-list finalists. That sequencing keeps qualification cost proportional to order risk — the tiered logic in our dual sourcing guide.

What Are the Limits of NAICS-Based Supplier Search?

NAICS codes classify industries for statistics, not products for buyers — a limitation worth stating plainly.

NAICS tells you a company’s primary industry, not what it stocks. BidLink’s critique is correct: for product-level sourcing, layer Federal Supply Codes — FSC 5961 (semiconductor devices) and FSC 5962 (microcircuits) — over the industry filter.

The classification problem is structural. One NAICS code per entity means a distributor that also assembles cable harnesses may be filed under 3359, invisible to your 334419 search. Conversely, a 334419 manufacturer may stock zero semiconductors. Product codes fix this from the demand side: government solicitations tag items with FSC 5961/5962, so searching award history by those codes reveals which companies have actually shipped semiconductors — evidence, not self-description.

Why does this matter? Because list quality drives RFQ response rates. A NAICS-only list yields many irrelevant contacts; layering FSC award history and D&B screens concentrates effort on firms with demonstrated semiconductor transactions. Our guides on choosing a Micron distributor and Texas Instruments distributor sourcing show how channel type changes verification depth.

When Should You Combine NAICS, FSC, and SBA Size Standards?

Each filter answers a different question; combining them turns a directory dump into a qualified supplier list.

Combine all three when you need defensible shortlists: NAICS 334419/334413 for industry, FSC 5961/5962 for product evidence, and the SBA 750-employee size standard when set-aside eligibility matters to your program.

The size standard deserves attention. Per the SBA small business size standards and the Federal Register notice of December 2, 2014, 334419’s threshold rose from 500 to 750 employees after NAICS 334411 merged into it in 2012. A supplier at 700 employees is “small” under 334419 but may exceed standards elsewhere — relevant if your customers are primes with small-business subcontracting goals, common in North American defense programs.

Here is the practical implication. Sequence the filters by cost: NAICS (free), SAM.gov exclusions (free), FSC award history (free), SBA size (free), D&B financials (paid, on shortlist), quality audit (finalists only). One EMS buyer cut a 400-name regional list to 22 qualified candidates in under two weeks using exactly this order. The same sequencing underpins our supplier qualification audit framework.

How Do Independent Distributors Fit Into NAICS 334419 Sourcing?

The code-based search surfaces many companies, but channel type — authorized, independent, or hybrid — determines how you buy from them.

Independent distributors frequently register under 334419 or wholesale codes and appear in these searches alongside manufacturers. They fit as shortage-bridging and obsolete-part sources, provided you verify AS6081 compliance and inspection capability first.

The three supplier types behave differently. Authorized distributors bring factory traceability and stable pricing but allocation queues. Independents bring spot stock and end-of-life coverage but shift verification to the buyer. A 334419-registered small manufacturer may do both — selling its own surplus through the same entity. The table summarizes the trade; the verification layers above apply to all three.

Factor	Authorized Distributor	Independent Distributor	334419-Registered Specialist
Traceability	Factory direct	Varies; require AS6081	Own product + surplus
Lead time	Allocation-dependent	Days from stock	Short for own lines
Obsolete parts	Rarely	Core business	Sometimes
Best for	Baseline production	Shortage bridging, EOL	Niche components

For OEM and EMS teams, the working model is a tiered approved vendor list: authorized channels for forecasted volume, vetted independents for gaps. Apply the same discipline as in our Micron authorized vs independent analysis and TI distributor sourcing guide.
