Electrical Wire Circular Connector 8da5-17z35sn 8da5 Series Amphenol Standard

8DA5-17Z35SN Circular Connector, 8D Series

The 8DA5-17Z35SN is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It belongs to the 8D series connector family (style A5). Note: The 8D series is a distinct connector standard, separate from MIL-DTL-38999 / GJB599, MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), and JY27466 (GJB), and is not directly form-fit-function interchangeable with D38999/J599 Series III, MS27484, MS27497, MS27508, or JY27466 connectors unless confirmed by the supplier.

This connector features shell size 17 (approximately equivalent to D38999 shell size E / 17), insert arrangement 35 (13 contacts: 13 x #22D signal, Service Class M - sealed), socket contacts (S), and normal keying (N). The "A5" style designation indicates a specific connector configuration within the 8D series (confirm exact style meaning with supplier). The shell letter "Z" is a non-standard designator — confirm exact meaning with supplier. The design supports EMI shielding and removable crimp contacts.

Related options: 8DA5-17Z35PN with pin contacts; 8DA5-15Z35SN for smaller shell size 15 (approx. D38999 size D / 15); 8DA5-19Z35SN for larger shell size 19 (approx. D38999 size F / 19); 8DA5-17Z02SN non-sealed power arrangement (Service Class I). Important: 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 "A5" style code, "Z" shell letter, and exact 8D series standard must be confirmed with supplier.

Compatible Applications

The 8DA5-17Z35SN connector is intended for platforms that require 8D series compliant interconnects with medium-count sealed signal circuits in shell size 17, using socket contacts. Typical use cases include:

• Aircraft and helicopter wiring harness interconnects (8D series standard)
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and outdoor equipment requiring sealed circular connectors
• Programs that standardize on 8D series interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, contact gender, and normal keying before mating. Confirm the meaning of the "A5" style code and "Z" shell letter with supplier.
• Use the correct crimp tooling for #22D signal contacts specified by arrangement 35.
• Fully engage the coupling mechanism with the mating 8D series connector until securely seated.
• Mate only with 8D series connectors of the same shell size, arrangement, opposite contact gender (pin), and normal keying. Note: arrangement 35 is Service Class M (sealed) — suitable for applications requiring environmental sealing.
• Do NOT attempt to mate with D38999/J599 Series III, MS27484, MS27497, MS27508, or JY27466 connectors — 8D series is a different standard and is not interchangeable unless confirmed by supplier.

Why Choose 8DA5-17Z35SN

8D Series Compliance

Choosing 8DA5-17Z35SN ensures compliance with 8D series requirements for programs that mandate this specific connector family. The connector geometry supports reliable interconnect with sealed signal capability, socket contacts, and normal keying for aerospace and industrial systems. Note: this connector is NOT a direct replacement for D38999/J599 Series III, MS27484, MS27497, MS27508, or JY27466 parts. Confirm exact specifications, "A5" style meaning, "Z" shell letter meaning, and interchangeability with supplier.

Ordering Information

Order by the designation 8DA5-17Z35SN. When requesting a quote, please confirm mating connector part number (pin contacts), shell finish, contact plating, "A5" style code meaning, "Z" shell letter meaning, exact 8D series standard, and required quantity. Note: arrangement 35 is Service Class M (sealed); specify arrangement 02 for non-sealed power applications.
