MS27473T20F35SN Threaded Plug, MIL-DTL-27473
The MS27473T20F35SN is a triple-start threaded circular electrical connector threaded plug designed for aerospace, avionics, and industrial platforms. It conforms to MIL-DTL-27473 (formerly MS27473) requirements. Note: MIL-DTL-27473 is a distinct standard, separate from MIL-DTL-38999 / GJB599, MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), MIL-DTL-26482 (62GB), JY27466 (GJB), 8D series, Y50 series, YLH series, ZH8525 series, YH3116 series, YW1 series, and SMA RF coaxial connectors, and is not directly form-fit-function interchangeable with any of those connectors unless confirmed by the supplier.
This threaded plug features shell size 20 (approximately equivalent to D38999 shell size G / 21), shell letter F, insert arrangement 20F-35 (13 contacts: 13 x #22D signal, Service Class M - sealed), socket contacts (S), and normal keying (N). The "T" style designation indicates a threaded coupling type. The design supports EMI shielding, scoop-proof mating, self-locking threaded coupling, and removable crimp contacts.

Installation Notes
- Verify shell size 20, insert arrangement 20F-35, socket contacts, and normal keying before mating.
- Use the correct crimp tooling for #22D signal contacts specified by arrangement 20F-35.
- Fully engage the triple-start threaded coupling with the mating MS27473 connector until securely seated.
- Mate only with MIL-DTL-27473 (MS27473) connectors of the same shell size 20, shell letter F, arrangement 20F-35, opposite contact gender (pin), and normal keying. Note: arrangement 20F-35 is Service Class M (sealed) — suitable for environments requiring environmental sealing.
- Do NOT attempt to mate with D38999/J599 Series III, MS27484, MS27497, MS27508, 62GB/MIL-DTL-26482, JY27466, 8D, Y50, YLH, ZH8525, YH3116, YW1 series, or SMA RF coaxial connectors — MIL-DTL-27473 is a different standard and is not interchangeable unless confirmed by supplier.
