Compatibility with Connector

TVP00RF-23-151SA-LC vs TVP00RF-23-151S-LC are compatible with TVP00RF-23-151PA mating connector. What are the differences?

I don’t believe CTVP00RF-23-151SA-LC or TVP00RF-23-151S-LC would be compatible with TVP00RF-23-151PA Amphenol Corporation | Circular Connector Assemblies | DigiKey Marketplace. It looks like you’re trying to mate a panel mount receptacle (female sockets) with another panel mount receptacle (male pins) and the added A suffix is alternate keying option, so a PA would not mate with an S.
