AT04-4P-WHT Equivalent & Substitute Parts

Part Overview

The AT04-4P-WHT is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp as part of the AT Series™ product line. This component functions as a receptacle housing for male pin contacts in free-hanging, in-line configurations. The part is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative color options or inventory availability necessitate component selection from the AT04-4P base product family.

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-WHT are identified from the AT04-4P base product family. All substitute parts share identical electrical and mechanical specifications with the main part, including connector type, contact type, number of positions, number of rows, mounting type, contact termination method, fastening type, insulation material, operating temperature range, sealed features, and compliance certifications. The substitution logic is based on the base product number AT04-4P, which defines the core connector architecture. Variations exist only in housing color, which does not affect electrical or mechanical compatibility. All substitute parts maintain the same RoHS3 compliance, MSL rating, and REACH status. Substitute parts are functionally interchangeable when color differentiation is not a design requirement.

Engineering Selection Recommendations

All substitute parts listed—AT04-4P-BLU, AT04-4P-BRN, AT04-4P-GRN, and AT04-4P-ORG—are Active product status components with identical electrical and mechanical specifications to the AT04-4P-WHT. Each substitute part carries full RoHS3 compliance certification and maintains REACH unaffected status. All parts are manufactured by Amphenol Sine Systems Corp within the AT Series™ product line. Selection among these parts is determined by application-specific color requirements for circuit identification, wiring harness organization, or system documentation standards. When color differentiation is not a functional requirement, any substitute part from this group provides equivalent performance and reliability characteristics. All parts are packaged in boxes and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-WHT and AT04-4P-BLU electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including connector type (receptacle), contact type (male pin), number of positions (4), number of rows (2), contact termination method (crimp), and fastening type (latch holder). The only difference is housing color.

Q: Can I substitute AT04-4P-ORG for AT04-4P-WHT in my assembly?

A: Yes, provided color differentiation is not a design requirement. All mechanical and electrical parameters are identical, including operating temperature range (-55°C ~ 125°C), sealed features, thermoplastic insulation material, and compliance certifications.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. All parts in this group—AT04-4P-WHT, AT04-4P-BLU, AT04-4P-BRN, AT04-4P-GRN, and AT04-4P-ORG—are RoHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited).

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

A: The base product number is AT04-4P. All substitute parts are variants of this base product, differentiated only by housing color designation.

Q: Are contacts included with these receptacle housings?

A: No. All parts in this group are housings only. Contacts are not included and must be sourced separately.

Q: What mounting configuration do these connectors support?

A: All parts support free-hanging, in-line mounting type with latch holder fastening. Contact termination is crimp-style.

Q: Can I use these parts in high-temperature applications?

A: Yes. All parts maintain operating temperature range of -55°C ~ 125°C, supporting both low and high-temperature industrial applications.
