The JY3470A2039PN is a bayonet-coupling circular electrical connector receptacle designed for aerospace, avionics, and industrial platforms. It conforms to GJB598 Series 2 / JY3470 requirements and is interchangeable with the MS3470A20-39PN designation used in MIL-DTL-26482 Series II supply chains.
This Class A narrow-flange panel receptacle features shell size 20, insert arrangement 20-39 (39 contacts), pin contacts (P), and normal keying (N). The design supports environment-resistant sealing, scoop-proof bayonet mating, and removable crimp contacts for reliable signal and power interconnect.

Related options: JY3470L2039PN / MS3470L20-39PN uses electroless nickel finish (L); socket versions use S contacts; alternate keying uses A–W positions as applicable. Wide-flange and jam-nut receptacles are covered by JY3472 / JY3474 families. There is no functional difference between JY3470 and MS3470 prefixes for form-fit-function mating within the same Series II family.
The JY3470A2039PN narrow flange receptacle is intended for platforms that require compact, environment-resistant bayonet interconnects with high contact count. Typical use cases include:
| Requirement | Recommended Choice |
|---|---|
| Narrow flange receptacle, size 20 / arrangement 39 / pins / keying N | JY3470A2039PN - this product |
| Same receptacle with nickel finish | JY3470L2039PN (MS3470L20-39PN) |
| Matching plug with socket contacts | JY3475 / JY3476, shell size 20, arrangement 39, S contacts, keying N |
| Wide flange or jam-nut mounting | JY3472 or JY3474 series with the same size, arrangement, and keying |
Choosing JY3470A2039PN ensures form-fit-function compatibility with MS3470A20-39PN supply chains while meeting GJB598 Series 2 requirements. The narrow-flange bayonet receptacle geometry supports fast mating, environmental durability, and reliable multi-circuit interconnect in aerospace and industrial systems.
Order by the GJB598 designation JY3470A2039PN (also written JY3470A20-39PN), or cross-reference as MS3470A20-39PN, depending on your procurement standard. When requesting a quote, please confirm mating plug part number, contact plating, mounting panel cut-out, and required quantity.
