JY27467T19F08PA Bayonet Circular Connector Plug, GJB599 Series I / D38999 Series I

The JY27467T19F08PA is a bayonet-coupling circular electrical connector plug designed for aerospace, avionics, and industrial platforms. It conforms to GJB599A Series I requirements and is interchangeable with the MS27467T19F08PA designation used in D38999 Series I supply chains.

This T-class plug features a threaded rear for backshell accessories, shell size 19, electroless nickel finish (F), insert arrangement 08, pin contacts (P), and alternate keying position A. The design supports EMI/RFI shielding, scoop-proof mating, and removable crimp contacts in a compact, high-reliability interconnect package.

Product Features

• Conformant to GJB599A Series I (equivalent to D38999 / MS27467 Series I style)
• Interchangeable with cross-reference part number MS27467T19F08PA
• Three-point bayonet quick-coupling for fast, vibration-resistant mating
• Threaded rear (T class) for GJB1784 / M85049 style backshell accessories
• Electroless nickel shell finish (F) for corrosion resistance and conductivity

Part Number Breakdown

Related options: JY27467T19B08PA uses olive drab cadmium finish (B); socket versions use S contacts; normal keying uses N. Confirm insert arrangement contact sizes and counts from the official arrangement chart before harness design. There is no functional difference between JY and MS prefixes for form-fit-function mating within the same Series I family.

Compatible Applications

The JY27467T19F08PA circular plug is intended for platforms that require compact, sealed, EMI-capable bayonet interconnects with secure mating. Typical use cases include:

• Aircraft and helicopter wiring harnesses
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and outdoor equipment requiring sealed circular connectors
• Industrial systems that standardize on GJB599 / D38999 Series I interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, contact gender, finish, and keying before mating.
• Use the correct crimp tooling and contact size specified for arrangement 08.
• Keep connector interfaces clean and capped when not in use to protect sealing surfaces.
• Select a matching T-class compatible backshell for the 1.0625-18 UNEF rear thread.
• Apply the recommended coupling engagement and, where required, use anti-loosening methods on accessories such as safety wire or thread-locking compound.
