J36B-74T Circular Connector, J36B Series (GJB)

The J36B-74T is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It conforms to J36B (GJB) series requirements. Note: J36B is a distinct standard, separate from MIL-DTL-26482 Series 1 (MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-38999 / GJB599, MIL-DTL-27473 (MS27473), MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), JY27466 (GJB), JY3470 (GJB), J30J series (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 connector features configuration 74 (shell size/arrangement — confirm exact meaning with supplier), "T" style code (connector type/design variant — confirm exact meaning with supplier), and contact gender/keying not explicitly designated in the part number (confirm with supplier). The design supports EMI shielding, threaded coupling, and removable crimp contacts.

Selection Guide

Installation Notes

• Verify configuration 74, "T" style code, contact gender, and keying before mating. Confirm the configuration 74 meaning, "T" style code meaning, contact gender, and keying with supplier.
• Use the correct crimp tooling for the contact type specified by configuration 74 (confirm contact size with supplier).
• Fully engage the threaded coupling with the mating J36B connector until securely seated.
• Mate only with J36B (GJB) connectors of the same configuration 74, "T" style, and opposite contact gender.
• Do NOT attempt to mate with MIL-DTL-26482 Series 1 (MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-27473, MIL-DTL-27484, D38999/J599 Series III, MS27497, MS27508, JY27466, JY3470, J30J, 8D, Y50, YLH, ZH8525, YH3116, YW1 series, or SMA RF coaxial connectors — J36B is a different standard and is not interchangeable unless confirmed by supplier.
