AT04-3P-WHT Equivalent & Substitute Parts
Part Overview
The AT04-3P-WHT is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp in the AT Series™. 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 and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative color options or inventory availability necessitate component selection from the AT04-3P family.

Substitute Part Grouping Explanation
Substitute parts for the AT04-3P-WHT are determined by equivalence across all electrical and mechanical parameters within the AT04-3P base product family. The substitution logic is based on the following criteria:
Substitution-Determining Parameters:
- Connector Type: Receptacle
- Contact Type: Male Pin
- Number of Positions: 3
- Number of Rows: 2
- Mounting Type: Free Hanging (In-Line)
- Contact Termination: Crimp
- Fastening Type: Latch Holder
- Insulation Material: Thermoplastic
- Operating Temperature Range: -55°C ~ 125°C
- Features: Sealed
- RoHS Status: ROHS3 Compliant
- MSL: 1 (Unlimited)
- REACH Status: REACH Unaffected
Variable Parameter:
- Color: The only parameter that differs among substitute parts. Color variants do not affect electrical or mechanical compatibility.
All substitute parts maintain identical functional specifications and are manufactured by Amphenol Sine Systems Corp within the AT Series™. Substitution is valid when color differentiation is not a functional requirement.

Engineering Selection Recommendations
All substitute parts within the AT04-3P family are Active product status and maintain full ROHS3 compliance and REACH Unaffected certification. Selection among AT04-3P-WHT, AT04-3P-BLU, AT04-3P-GRN, AT04-3P-ORG, and AT04-3P-YEL is determined by color requirement and inventory availability.
The AT04-3P-GRN variant currently maintains the highest inventory level at 1,776 pieces. The AT04-3P-WHT maintains 828 pieces in stock. All variants are functionally equivalent for applications requiring 3-position rectangular connector receptacle housings with male pin contacts, crimp termination, latch fastening, sealed construction, and operation across the -55°C to 125°C temperature range.
Component selection should be based on color coding requirements within the application. When color is not a functional constraint, any variant from the AT04-3P family provides equivalent electrical and mechanical performance.
Frequently Asked Questions (FAQ)
Q: Can AT04-3P-BLU be used in place of AT04-3P-WHT?
A: Yes. Both parts are functionally equivalent rectangular connector receptacle housings with identical electrical and mechanical specifications. The only difference is housing color. Substitution is valid when color coding is not a functional requirement.
Q: Are all AT04-3P variants compatible with the same male pin contacts?
A: Yes. All AT04-3P variants accept the same male pin contacts. The housing color does not affect contact compatibility or electrical performance.
Q: What is the operating temperature range for these connector housings?
A: All AT04-3P variants operate across -55°C to 125°C. This range is consistent across all color options.
Q: Are these parts RoHS compliant?
A: Yes. All AT04-3P variants are ROHS3 compliant and REACH Unaffected.
Q: What does MSL 1 (Unlimited) mean for these parts?
A: MSL 1 indicates Moisture Sensitivity Level 1, which means unlimited shelf life without special moisture control storage requirements.
Q: Can I substitute AT04-3P-ORG for AT04-3P-WHT in a production assembly?
A: Substitution is valid from an electrical and mechanical standpoint. However, if the assembly design specifies white housing for color-coded identification or traceability purposes, substitution would not be appropriate. Verify color requirements in the application specification.
Q: What is the difference between the AT04-3P variants?
A: The AT04-3P variants differ only in housing color. All other parameters including connector type, position count, row configuration, mounting type, termination method, fastening type, insulation material, temperature range, and compliance certifications are identical.
Q: Are contacts included with these connector housings?
A: No. All AT04-3P variants are housings only. Male pin contacts must be sourced separately and crimped into the housing.
