AT04-3P-SR02RED Equivalent & Substitute Parts

Part Overview

The AT04-3P-SR02RED is a 3-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 red housing variant is actively produced and maintained in inventory.

Substitute parts are identified to provide alternative options when the primary red housing variant is unavailable or when application requirements permit housing color variation while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The AT04-3P-SR02RED receptacle housing is substitutable with the AT04-3P-SR02GRY based on the following criteria:

Both parts share identical specifications across all critical electrical and mechanical parameters:

• Same base product number (AT04-3P)
• Same connector type (Receptacle)
• Same contact type (Male Pin)
• Same number of positions (3)
• Same number of rows (2)
• Same mounting type (Free Hanging, In-Line)
• Same contact termination method (Crimp)
• Same fastening type (Latch Holder)
• Identical feature set (Cap/Cover, IP68, IP69K, Reduced Wire Seals, Strain Relief)
• Same insulation material (Thermoplastic)
• Same operating temperature range (-55°C ~ 125°C)
• Same RoHS compliance status (ROHS3 Compliant)
• Same REACH status (REACH Unaffected)
• Same ECCN classification (EAR99)
• Same HTSUS code (8538.90.6000)

The only difference between these parts is the housing color: red versus gray. This substitution is valid when application requirements do not mandate a specific housing color.

Parameter Comparison

Engineering Selection Recommendations

Both AT04-3P-SR02RED and AT04-3P-SR02GRY are active products with full ROHS3 compliance and REACH unaffected status. Both maintain identical electrical performance, mechanical compatibility, and environmental ratings (IP68, IP69K).

Selection between these parts should be based on application-specific requirements:

• AT04-3P-SR02RED: Select when red housing color is specified or required for circuit identification, wiring harness organization, or system design standards.

• AT04-3P-SR02GRY: Select when gray housing color is acceptable or preferred, or when the red variant is unavailable. This variant currently maintains higher inventory levels (1489 pieces versus 620 pieces).

Both parts are suitable for applications requiring crimp termination, free-hanging mounting, and operation across the -55°C to 125°C temperature range. The choice between red and gray housing does not affect connector performance, durability, or compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can AT04-3P-SR02GRY be used as a direct replacement for AT04-3P-SR02RED?

A: Yes, the gray variant (AT04-3P-SR02GRY) is a direct functional equivalent to the red variant (AT04-3P-SR02RED). All electrical, mechanical, and environmental specifications are identical. The only difference is housing color.

Q: Are there any compatibility issues when substituting the gray housing for the red housing?

A: No compatibility issues exist from an electrical or mechanical standpoint. Both housings accept the same male pin contacts, use identical crimp termination, and feature the same latch holder fastening system. Substitution is valid unless application documentation specifically requires red housing color.

Q: Do both parts support the same operating temperature range?

A: Yes, both AT04-3P-SR02RED and AT04-3P-SR02GRY operate across the identical temperature range of -55°C to 125°C.

Q: Are both parts RoHS compliant?

A: Yes, both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between these two part numbers?

A: The only difference is the housing color. AT04-3P-SR02RED features a red housing, while AT04-3P-SR02GRY features a gray housing. All other specifications, including connector type, position count, termination method, and performance ratings, are identical.

Q: Can I mix red and gray housings in the same application?

A: Yes, from a technical standpoint, red and gray housings can be used together in the same application without functional issues. However, application design standards or wiring harness organization schemes may dictate housing color consistency.

Q: What is the base product number for both parts?

A: Both AT04-3P-SR02RED and AT04-3P-SR02GRY share the base product number AT04-3P, indicating they are variants of the same core connector housing design.

Q: Are contacts included with these housings?

A: The AT04-3P-SR02RED includes contacts as part of the standard package. The AT04-3P-SR02GRY is supplied as a housing only, with contacts not included. Verify contact requirements when selecting between these variants.
