AT04-2P-SR02WHT Equivalent & Substitute Parts

Part Overview

The AT04-2P-SR02WHT is a 2-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 mounting applications. The housing features crimp contact termination with latch holder fastening and includes integrated strain relief, reduced wire seals, and environmental protection rated to IP68 and IP69K standards.

The AT04-2P-SR02WHT maintains Active product status with 982 units currently in stock. Substitute parts are identified based on identical electrical and mechanical specifications with variations limited to housing color. Color variants do not affect connector functionality, electrical performance, or environmental ratings, making them direct functional equivalents for applications where housing color is not a critical design parameter.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-2P-SR02WHT are identified within the ATSeries™SR02 rectangular connector housing family. Substitution is valid when all electrical and mechanical parameters remain identical across the following critical specifications:

Substitution-Determining Parameters:

• Connector Type: Receptacle
• Number of Positions: 2
• Contact Type: Male Pin
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Features: Cap (Cover), IP68, IP69K, Reduced Wire Seals, Strain Relief
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Base Product Number: AT04-2P
• Series: ATSeries™SR02
• Manufacturer: Amphenol Sine Systems Corp

The identified substitute parts AT04-2P-SR02GRY and AT04-2P-SR02RED differ only in housing color (Gray and Red, respectively). Housing color is a cosmetic and identification parameter that does not affect electrical performance, mechanical compatibility, environmental protection ratings, or thermal operating characteristics. All substitute parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and are classified as Active products.

Parameter Comparison

Engineering Selection Recommendations

All three rectangular connector housings—AT04-2P-SR02WHT, AT04-2P-SR02GRY, and AT04-2P-SR02RED—are functionally equivalent for applications requiring a 2-position receptacle connector with crimp termination, latch holder fastening, and IP68/IP69K environmental protection.

Selection Criteria Based on Product Status and Compliance:

All substitute parts maintain Active product status, confirming ongoing manufacturer support and availability. All parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement in regulated industries.

Inventory Availability:

The AT04-2P-SR02GRY variant has the highest inventory level at 1565 units, followed by AT04-2P-SR02RED at 1160 units, and AT04-2P-SR02WHT at 982 units. Selection between color variants may be influenced by supply chain requirements and lead time considerations.

Application-Specific Considerations:

Housing color selection should be based on system integration requirements, cable identification protocols, or visual assembly verification procedures. The thermoplastic insulation material and operating temperature range of -55°C to 125°C are identical across all variants, confirming suitability for equivalent thermal environments.

Frequently Asked Questions (FAQ)

Q: Can AT04-2P-SR02GRY or AT04-2P-SR02RED be used as direct replacements for AT04-2P-SR02WHT?

A: Yes. All three parts share identical electrical and mechanical specifications, including connector type, position count, contact termination method, fastening mechanism, and environmental ratings. The only difference is housing color, which does not affect functional performance or compatibility.

Q: Are there any compatibility issues when substituting between color variants?

A: No. The rectangular connector housings are mechanically and electrically interchangeable. Mating connectors, contact pins, and all interface specifications remain unchanged across color variants.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -55°C to 125°C, confirming thermal equivalence for applications requiring extended temperature performance.

Q: What is the significance of the Base Product Number AT04-2P?

A: The Base Product Number AT04-2P identifies the core connector housing design within the ATSeries™SR02 family. Color variants (WHT, GRY, RED) are designated by the suffix following SR02, indicating that all variants share the same fundamental design and specifications.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. All three rectangular connector housings—AT04-2P-SR02WHT, AT04-2P-SR02GRY, and AT04-2P-SR02RED—are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for procurement in restricted substance environments.

Q: What does the IP68 and IP69K rating indicate?

A: IP68 and IP69K are ingress protection ratings. IP68 indicates complete dust protection and submersion capability up to specified depths. IP69K indicates high-pressure, high-temperature jet protection. Both ratings are present on all substitute parts, confirming equivalent environmental sealing performance.

Q: Is there a difference in packaging between the color variants?

A: All parts are supplied in Box packaging. Packaging format is consistent across all substitute parts.

Q: What is the contact termination method for these connectors?

A: All parts use crimp contact termination, requiring specialized crimping tools and procedures for wire attachment. This termination method is identical across all color variants.
