The FA1-NBRP-PCB-9: It uses a locking ramp fastening system — the ramp clicks into the mating receptacle and holds under vibration, which is why Fakra connectors are common in automotive antenna and infotainment harnesses. Code B keying means the housing plastic has a specific mechanical key position — a Code B plug only mates with a Code B receptacle, preventing cross-mating in multi-port systems.
Sourcing Reality — Obsolete, Sourced to Order
This part is officially listed as Obsolete. Amphenol RF no longer manufactures it as a standard catalog item. No official successor order code appears on record.
This plug mates with any SMB Fakra Code B receptacle — the locking ramp and keying are the interface, not the brand.
