JY27467T13B308PN Bayonet Circular Connector Plug, GJB599 Series I / D38999 Series I
The JY27467T13B308PN 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 MS27467T13B308PN designation used in D38999 Series I / HE308-style supply chains.
This T-class plug features a threaded rear for backshell accessories, shell size 13, olive drab cadmium finish (B), insert arrangement 308, pin contacts (P), and normal keying (N). The design supports EMI/RFI shielding, scoop-proof mating, and removable crimp contacts in a compact Series I package.
Product Features
- Conformant to GJB599A Series I (equivalent to D38999 / MS27467 / HE308 Series I style)
- Interchangeable with cross-reference part number MS27467T13B308PN
- Three-point bayonet quick-coupling for fast, vibration-resistant mating
- Threaded rear (T class) for GJB1784 / M85049 style backshell accessories
- Olive drab cadmium shell finish (B) for corrosion resistance and conductivity
- Pin contact configuration (P) with insert arrangement 308 (commonly aligned with shell-13 eight-contact layouts such as 13-08 / 8 x #20; confirm on chart)
- Five-key polarization with normal keying (N) for standard anti-mismatch mating

Related options: JY27467T13F308PN uses electroless nickel finish; socket versions use S contacts; alternate keying uses A–E. If your drawing calls out arrangement 08 / 13-08, confirm whether JY27467T13B08PN is the required cross-reference before ordering. There is no functional difference between JY and MS prefixes for form-fit-function mating within the same Series I family.
Compatible Applications
The JY27467T13B308PN circular plug is intended for platforms that require compact, sealed 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
