AT04-6P-SR02YEL Equivalent & Substitute Parts

Part Overview

The AT04-6P-SR02YEL is a 6-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp, part of the ATSeries™SR02 product line. This connector housing is designed for free-hanging, in-line applications with crimp contact termination and latch holder fastening. The yellow housing variant is actively produced and stocked with 1024 units in inventory.

Substitute parts are necessary when specific color coding requirements differ from the primary yellow housing, while maintaining identical electrical and mechanical specifications. All substitute parts share the same base product number (AT04-6P) and connector architecture, ensuring direct functional interchangeability.

Substitute Part Grouping Explanation

The AT04-6P-SR02YEL connector housing has four parametric equivalents that differ only in housing color. Substitution is valid based on the following criteria:

Substitution-Determining Parameters:

Base Product Number: AT04-6P (identical across all variants)
Connector Type: Receptacle (identical)
Number of Positions: 6 (identical)
Number of Rows: 3 (identical)
Contact Type: Male Pin (identical)
Mounting Type: Free Hanging (In-Line) (identical)
Contact Termination: Crimp (identical)
Fastening Type: Latch Holder (identical)
Operating Temperature Range: -55°C ~ 125°C (identical)
Features: Cap (Cover), IP68, IP69K, Reduced Wire Seals, Strain Relief (identical)
Insulation Material: Thermoplastic (identical)
Compliance: ROHS3 Compliant, REACH Unaffected (identical)

Variable Parameter:

Housing Color: Yellow (primary), Blue, Gray, Red, White (substitutes)

All substitute parts maintain identical electrical and mechanical performance characteristics. Housing color selection is determined by application-specific requirements such as circuit identification, wiring harness organization, or system design standards.

Frequently Asked Questions (FAQ)

Q: Can AT04-6P-SR02BLU be used as a direct replacement for AT04-6P-SR02YEL?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, position count, row configuration, contact termination method, fastening mechanism, operating temperature range, and protective features. The only difference is housing color.

Q: Are there any performance differences between the color variants?

A: No. All color variants of the AT04-6P-SR02 series maintain identical performance characteristics. Housing color is a cosmetic and identification feature only and does not affect electrical or mechanical function.

Q: What is the purpose of offering multiple housing colors?

A: Housing color variants enable circuit identification, wiring harness organization, and compliance with system design standards. Color coding improves assembly accuracy and maintenance procedures in complex connector systems.

Q: Are contacts included with these connector housings?

A: The AT04-6P-SR02GRY variant is documented as "Contacts Not Included." Verify contact inclusion status with the supplier for all other color variants before procurement.

Q: Do all variants support the same operating temperature range?

A: Yes. All AT04-6P-SR02 color variants operate across the identical temperature range of -55°C to 125°C.

Q: What is the significance of the IP68 and IP69K ratings?

A: These ingress protection ratings indicate the connector housing provides complete dust protection (IP68) and high-pressure water jet protection (IP69K), suitable for harsh environmental applications.

Q: Can these connectors be used interchangeably in the same assembly?

A: Yes, from a functional standpoint. However, application-specific color coding requirements may restrict substitution based on system design specifications or assembly procedures.
