Need a custom version from drawing?
We coordinate supplier-qualified RF connector and cable assembly sourcing from drawings, samples, or BOM. Typical production lead time is 3–6 weeks after drawing/spec review; feasibility, MOQ, and fit are confirmed by RFQ.
Before RFQ Clear inputs speed up review. ⌄
- • Share the reference MPN and source brand if it matters.
- • Add the BOM and volume split for production projects.
- • Attach the drawing or the key fit requirements.

Description
Current reference data for 142-0701-421: 50 Ohms · 18 GHz · PCB Mount. The catalog currently lists the configuration as: Straight · Solder. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 18 GHz. The real operating limit still depends on the assembly, mating pair, and application context. For higher-frequency projects, include the drawing, cable path, and critical requirements in the first RFQ. Mounting is listed as PCB Mount. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. Material is listed as Brass. That is useful for review, but it does not replace full project stack-up confirmation. Use this page to shortlist before RFQ, not as the final sign-off.
Use this page to shortlist before RFQ. MOQ 200+ custom production and supply path are confirmed after drawing/spec/BOM review; no spot stock is assumed.
