Y50EA08-04ZJ2 Circular Connector, Y50 Series

The Y50EA08-04ZJ2 is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It belongs to the Y50 series connector family (style EA). Note: The Y50 series is a distinct connector standard, separate from MIL-DTL-38999 / GJB599, MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), JY27466 (GJB), and 8D series, and is not directly form-fit-function interchangeable with D38999/J599 Series III, MS27484, MS27497, MS27508, JY27466, or 8D series connectors unless confirmed by the supplier.

This connector features shell size 08 (approximately equivalent to D38999 shell size A / 9), insert arrangement 04 (3 contacts: 3 x #16S power, Service Class I - non-sealed), and the "EA" style designation indicates a specific connector configuration within the Y50 series (confirm exact style meaning with supplier). The "Z" designator likely indicates a finish or material code, and "J2" indicates a keying or variant code — both require supplier confirmation. The design supports EMI shielding and removable crimp contacts.

Part Number Breakdown

Related options: Y50EA08-04ZJ2 with opposite contact gender (confirm part number with supplier); Y50EA10-04ZJ2 for larger shell size 10 (approx. D38999 size B / 11); Y50EA08-35ZJ2 sealed signal arrangement (Service Class M, 13 x #22D); Y50EA06-04ZJ2 for smaller shell size 06. Important: Y50 series, 8D series, JY27466 (GJB), MS27484 (MIL-DTL-27484), MS27497 (MIL-DTL-27497), MS27508 (MIL-DTL-27508), and D38999/J599 (MIL-DTL-38999/GJB599) are separate standards and are NOT form-fit-function interchangeable unless confirmed by supplier. The "EA" style code, "Z" designator, "J2" keying code, contact gender, and exact Y50 series standard must be confirmed with supplier.

Compatible Applications

The Y50EA08-04ZJ2 connector is intended for platforms that require Y50 series compliant interconnects with low-count non-sealed power circuits in shell size 08. Typical use cases include:

• Aircraft and helicopter wiring harness interconnects (Y50 series standard)
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and industrial equipment requiring power circular connectors
• Programs that standardize on Y50 series interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, contact gender, and keying before mating. Confirm the meaning of the "EA" style code, "Z" designator, "J2" keying code, and contact gender with supplier.
• Use the correct crimp tooling for #16S power contacts specified by arrangement 04.
• Fully engage the coupling mechanism with the mating Y50 series connector until securely seated.
• Mate only with Y50 series connectors of the same shell size, arrangement, opposite contact gender, and compatible keying. Note: arrangement 04 is Service Class I (non-sealed) — not suitable for applications requiring environmental sealing.
• Do NOT attempt to mate with D38999/J599 Series III, MS27484, MS27497, MS27508, JY27466, or 8D series connectors — Y50 series is a different standard and is not interchangeable unless confirmed by supplier.

Why Choose Y50EA08-04ZJ2

Y50 Series Compliance

Choosing Y50EA08-04ZJ2 ensures compliance with Y50 series requirements for programs that mandate this specific connector family. The connector geometry supports reliable interconnect with non-sealed power capability for aerospace and industrial systems. Note: this connector is NOT a direct replacement for D38999/J599 Series III, MS27484, MS27497, MS27508, JY27466, or 8D series parts. Confirm exact specifications, "EA" style meaning, "Z" designator meaning, "J2" keying code meaning, contact gender, and interchangeability with supplier.

Ordering Information

Order by the designation Y50EA08-04ZJ2. When requesting a quote, please confirm mating connector part number (opposite contact gender), shell finish, contact plating, "EA" style code meaning, "Z" designator meaning, "J2" keying code meaning, contact gender, exact Y50 series standard, and required quantity. Note: arrangement 04 is Service Class I (non-sealed); specify arrangement 35 for sealed signal applications.
