AT04-4P-SR01WHT Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR01WHT is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component belongs to the ATSeries™SR01 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 974 units available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector housings within the same series. Alternative part numbers may be required due to color availability, inventory allocation, or specific application requirements where housing color does not affect functional performance.

Engineering Selection Recommendations

Both the AT04-4P-SR01WHT and AT04-4P-SR01GRY are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application-specific requirements rather than technical performance differences.

The AT04-4P-SR01WHT (white housing) and AT04-4P-SR01GRY (gray housing) are functionally equivalent rectangular connector receptacles. Both parts maintain identical electrical specifications, mechanical dimensions, environmental protection ratings (IP68, IP69K), and operating temperature ranges (-55°C ~ 125°C).

Part selection should be based on:

Visual identification requirements: Applications requiring color-coded connector identification
Inventory availability: Current stock levels support both options
Regulatory compliance: Both parts satisfy ROHS3 and REACH requirements
Environmental specifications: Both parts provide sealed, strain-relieved housings with identical protection ratings

The AT04-4P-SR01GRY substitute maintains 1094 units in new original inventory, compared to 974 units for the main part number.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-SR01WHT and AT04-4P-SR01GRY mechanically compatible?

A: Yes. Both parts are 4-position rectangular connector receptacles with identical mechanical specifications, including mounting type (free hanging, in-line), fastening mechanism (latch holder), and housing dimensions. The only difference is housing color.

Q: Can these parts be used interchangeably in the same application?

A: Yes, provided that housing color does not affect application requirements. Both parts maintain identical electrical performance, environmental protection (IP68, IP69K), and operating temperature ranges (-55°C ~ 125°C).

Q: What is the difference between the main part and the substitute?

A: The AT04-4P-SR01WHT features a white housing, while the AT04-4P-SR01GRY features a gray housing. All other specifications, including connector type, position count, row configuration, termination method, and environmental ratings, are identical.

Q: Are both parts currently in production?

A: Yes. Both the AT04-4P-SR01WHT and AT04-4P-SR01GRY are classified as active production parts with current inventory availability.

Q: Do these parts require contacts to be purchased separately?

A: The AT04-4P-SR01GRY specification indicates that contacts are not included. Verify contact requirements for your specific application configuration.

Q: What environmental protection do these connectors provide?

A: Both parts provide IP68 and IP69K protection ratings with sealed housings and strain relief features, suitable for sealed, in-line connector applications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the AT04-4P-SR01WHT and AT04-4P-SR01GRY are ROHS3 compliant and REACH unaffected.
