Product details

75 Ohm MCX Plug for RG-179-Class Coax

The Amphenol RF 919-137P-71SX is an MCX-style plug (male pin) built for 75 Ohm signal paths — the impedance that matters for video, broadcast, and telecom, not the 50 Ohm version common in radio. It mates with any standard 75 Ohm MCX jack via a snap-on fastening, giving a positive lock without threads. This is the crimp-shield, solder-contact variant: you crimp the braid over the ferrule and solder the centre conductor into the pin. Rated to 6 GHz with 0.15 dB insertion loss — clean through C-band.

Cable Compatibility — No Guessing

This plug is dimensioned for RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179. That covers the common 75 Ohm miniature coax types used in CCTV, SDI video, and baseband data links.

Listed as Active — no end-of-life notice or last-time-buy on this order code.

Frequently asked questions

What is the replacement for 919-137P-71SX?

Part is Not For New Designs, so buyers need a functional alternative to avoid redesign.

Is 919-137P-71SX in stock and what is the lead time?

Immediate availability drives purchasing decisions and project schedules.

What cable types does the 919-137P-71SX work with?

Engineers must confirm cable group compatibility before ordering to ensure proper fit.

What is the price for 919-137P-71SX in bulk?

Sourcing buyers need pricing for BOM cost estimation and comparison.

Is 919-137P-71SX equivalent to a 75 ohm BNC plug from another manufacturer?

Cross-referencing ensures alternative sources if Amphenol RF stock is low.

What is the insertion loss of 919-137P-71SX?

Signal integrity matters for RF designs; datasheet value (0.15dB) must be confirmed.
