AT04-4P-SR02RED Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR02RED is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component belongs to the ATSeries™SR02 product line and is classified as a rectangular connector housing designed for free-hanging, in-line applications. The housing features a red thermoplastic body with integrated strain relief, reduced wire seals, and environmental sealing rated to IP68 and IP69K standards.

The AT04-4P-SR02RED maintains Active product status with 746 units currently in stock. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific application requirements necessitate alternative configurations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-SR02RED are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector Type: Receptacle housing only
• Number of Positions: 4-position configuration
• Number of Rows: 2-row arrangement
• Contact Type: Male pin acceptance
• Mounting Type: Free hanging, in-line orientation
• Contact Termination: Crimp termination method
• Fastening Type: Latch holder mechanism
• Features: Cap/cover, IP68/IP69K sealing, reduced wire seals, strain relief
• Insulation Material: Thermoplastic construction
• Operating Temperature Range: -55°C to 125°C
• Series: ATSeries™SR02
• Manufacturer: Amphenol Sine Systems Corp
• Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts differ only in housing color, which does not affect electrical performance or mechanical compatibility. All substitute parts maintain identical functional specifications and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-SR02RED and AT04-4P-SR02GRY maintain Active product status with full ROHS3 compliance and REACH unaffected certification. These parts are functionally equivalent across all electrical and mechanical specifications.

Selection between these parts is determined by application requirements related to housing color identification or system-level color coding standards. The AT04-4P-SR02GRY offers higher inventory availability at 1482 units compared to 746 units for the red variant, which may influence lead time considerations for high-volume procurement.

Both parts are suitable for applications requiring IP68 and IP69K environmental sealing across the full operating temperature range of -55°C to 125°C. The thermoplastic insulation material, crimp termination method, and latch holder fastening mechanism are identical across both variants.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-SR02RED and AT04-4P-SR02GRY electrically interchangeable?

A: Yes. Both parts are electrically identical. They feature the same 4-position, 2-row configuration with male pin contact acceptance, crimp termination, and latch holder fastening. Electrical performance and signal integrity are equivalent.

Q: What is the only difference between these substitute parts?

A: The housing color is the only difference. AT04-4P-SR02RED features a red thermoplastic body, while AT04-4P-SR02GRY features a gray thermoplastic body. All other specifications, including environmental ratings, operating temperature range, and mechanical features, are identical.

Q: Can I use AT04-4P-SR02GRY as a direct replacement for AT04-4P-SR02RED in existing assemblies?

A: Direct mechanical and electrical replacement is possible. However, if the application requires specific color identification for system integration, wiring harness organization, or visual circuit identification, the color difference must be evaluated against application requirements.

Q: Do both parts include contacts?

A: The AT04-4P-SR02RED includes contacts as part of the standard package. The AT04-4P-SR02GRY is specified as "Contacts Not Included," meaning contacts must be sourced separately for this variant.

Q: What environmental sealing ratings do these connectors provide?

A: Both parts are rated to IP68 and IP69K standards, providing protection against dust ingress and high-pressure water jets. These ratings apply across the full operating temperature range of -55°C to 125°C.

Q: Are these parts suitable for outdoor or harsh environment applications?

A: Yes. The IP68 and IP69K ratings, combined with thermoplastic insulation material, reduced wire seals, and strain relief features, make these connectors suitable for harsh environment applications. The operating temperature range of -55°C to 125°C supports both cold and elevated temperature environments.

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

A: The base product number is AT04-4P. The suffixes "-SR02RED" and "-SR02GRY" indicate the specific series variant and housing color.
