334417: Electronic Connector Manufacturing

What this code covers

NAICS 334417 covers manufacturing electronic connectors: coaxial and RF, cylindrical or circular, rack and panel, pin and sleeve, printed circuit board, and fiber optic types. Contacts, backshells and accessories are usually bought alongside them. Connectors for electrical rather than electronic use, such as plugs and receptacles for power, sit under 335931.

In defense the demand is dominated by standard military connectors: circular connectors to MIL-DTL-38999, MIL-DTL-5015 and MIL-DTL-26482, micro-D connectors to MIL-DTL-83513, D-subminiature to MIL-DTL-24308, RF connectors to MIL-PRF-39012, and board connectors to MIL-DTL-55302. DLA Land and Maritime manages most of these by national stock number and buys them in quantities from a handful to full production lots.

What federal buyers typically ask for

Almost every standard connector solicitation points to a qualified products list. The buyer will accept only a listed manufacturer, and a distributor must show the manufacturer's certificate of conformance with lot and date code. First article is rare for QPL parts and common for drawing-controlled specials. The DFARS counterfeit electronic part clause applies, so traceability back to the original manufacturer is not optional.

The DFARS specialty metals clause carries an exception for commercially available electronic components, but confirm how the buying activity applies it to your shells and contacts. Custom connectors and hermetic feedthroughs for named systems are often ITAR controlled and may require source approval as critical items.

Set-aside patterns follow the source list. Many DIBBS buys are small business set-asides, and on those the nonmanufacturer rule matters: a small distributor supplying a large manufacturer's connector needs a class waiver or an individual waiver to count. Large lots for new production usually go unrestricted to the manufacturers.
