AT04-4P-SR02WHT Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR02WHT 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 part is currently in active production status with 878 units available in new original inventory.

Substitute parts are identified when alternative models maintain identical electrical and mechanical specifications while differing only in non-functional attributes such as color or packaging configuration. Identifying equivalent parts ensures design flexibility, supply chain continuity, and component availability across manufacturing environments.

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-SR02WHT are identified based on strict equivalence across all functional and mechanical parameters. The substitution logic is based on the following criteria:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 4
• Number of Rows: 2
• 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
• Series: ATSeries™SR02
• Manufacturer: Amphenol Sine Systems Corp
• Base Product Number: AT04-4P

Allowable Variation:

• Color (White vs. Gray)
• Inventory levels
• Packaging configuration

Parts that maintain all mandatory matching parameters are classified as parametric equivalents and direct substitutes regardless of color designation.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-SR02WHT and AT04-4P-SR02GRY maintain active product status with full compliance to ROHS3 and REACH regulations. Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and trade purposes.

Selection between these parts is determined by application-specific requirements:

AT04-4P-SR02WHT (White): Primary selection when color specification is white or when color is not a constraint. Current inventory: 878 units.

AT04-4P-SR02GRY (Gray): Direct functional substitute when gray color is required or preferred. Current inventory: 1482 units. Note that contacts are not included with this variant.

Both parts support identical operating temperature ranges (-55°C to 125°C), feature sets (IP68, IP69K, reduced wire seals, strain relief), and mechanical configurations. Substitution between these parts introduces no electrical or mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can AT04-4P-SR02GRY be used as a direct replacement for AT04-4P-SR02WHT?

A: Yes. Both parts are parametric equivalents sharing identical connector type, position count, row configuration, mounting method, termination type, fastening mechanism, protective features, insulation material, and operating temperature range. The only difference is housing color.

Q: What does "Contacts Not Included" mean for the AT04-4P-SR02GRY variant?

A: This notation indicates that the gray housing is supplied without pre-installed contacts. The white variant (AT04-4P-SR02WHT) includes this same specification in its standard configuration. Contact procurement must be handled separately for both variants if required.

Q: Are there electrical performance differences between the white and gray versions?

A: No. Both versions maintain identical electrical specifications, including contact type (male pin), termination method (crimp), and protective ratings (IP68, IP69K).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection depends on color requirements and inventory availability. Both parts carry active product status and full regulatory compliance.

Q: Are these parts interchangeable in existing assemblies?

A: Yes, provided that color is not a functional or aesthetic requirement. All mechanical and electrical parameters are identical between the two variants.

Q: What is the significance of the ATSeries™SR02 designation?

A: This designation identifies the product family and series. Both substitute parts belong to the same series, confirming design compatibility and standardized specifications across the product line.
