AT04-3P-SR02WHT Equivalent & Substitute Parts

Part Overview

The AT04-3P-SR02WHT is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the ATSeries™SR02 product line and is classified as an active product. The housing is designed for free-hanging, in-line mounting applications with crimp contact termination and latch holder fastening. The white color variant is specified for applications requiring visual identification or aesthetic requirements. Substitute parts are identified to provide alternative options when the primary part is unavailable or when specific color or inventory requirements necessitate alternative selection.

Key Parameters

Substitute Part Grouping Explanation

The AT04-3P-SR02WHT has one identified parametric equivalent: AT04-3P-SR02GRY. Substitution between these parts is valid based on the following criteria:

Both parts share identical electrical and mechanical specifications across all critical parameters: connector type (receptacle), contact type (male pin), number of positions (3), number of rows (2), mounting type (free hanging in-line), contact termination method (crimp), fastening type (latch holder), and feature set (cap/cover, IP68, IP69K, reduced wire seals, strain relief). Both components operate across the same temperature range (-55°C ~ 125°C), utilize thermoplastic insulation material, and maintain equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected).

The primary distinction between these parts is the housing color: white for AT04-3P-SR02WHT and gray for AT04-3P-SR02GRY. This color variation does not affect functional compatibility or electrical performance. Both parts are manufactured by Amphenol Sine Systems Corp within the ATSeries™SR02 product line and share the same base product number (AT04-3P).

Parameter Comparison

Engineering Selection Recommendations

Both AT04-3P-SR02WHT and AT04-3P-SR02GRY are active products with equivalent compliance certifications. Selection between these parts should be based on application-specific requirements:

The AT04-3P-SR02WHT (white housing) is suitable for applications where color coding or visual identification is required. Current inventory status indicates 874 pieces available.

The AT04-3P-SR02GRY (gray housing) provides an alternative with higher current inventory availability at 1489 pieces. This part is functionally equivalent across all electrical and mechanical parameters. Note that the gray variant specification indicates contacts are not included with the housing.

Both parts maintain ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The identical operating temperature range (-55°C ~ 125°C), IP68/IP69K ratings, and feature set ensure functional interchangeability in applications where housing color does not present a constraint.

Frequently Asked Questions (FAQ)

Q: Can AT04-3P-SR02GRY be used as a direct replacement for AT04-3P-SR02WHT?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. The only difference is housing color (white versus gray). Substitution is valid when color specification is not a design requirement.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: connector type (receptacle), contact type (male pin), number of positions (3), number of rows (2), mounting type (free hanging in-line), contact termination method (crimp), fastening type (latch holder), operating temperature range (-55°C ~ 125°C), and feature set (cap/cover, IP68, IP69K, reduced wire seals, strain relief).

Q: Are there any compatibility issues between the white and gray variants?

A: No compatibility issues exist. Both variants are manufactured by Amphenol Sine Systems Corp within the same ATSeries™SR02 product line and share the base product number AT04-3P.

Q: What does the note "Contacts Not Included" on the gray variant mean?

A: This indicates that the AT04-3P-SR02GRY housing is supplied without pre-installed contacts. Contacts must be obtained separately and crimped into the housing during assembly. The white variant (AT04-3P-SR02WHT) specification does not include this note.

Q: Are both parts compliant with current regulations?

A: Yes. Both AT04-3P-SR02WHT and AT04-3P-SR02GRY are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent applications.
