Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-4P-SR01RED is determined by strict equivalence across the following critical parameters:

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, Sealed, Strain Relief
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Series: ATSeries™SR01
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter Permitted for Substitution:

• Color: Housing color variation is permitted when electrical and mechanical specifications remain identical

The substitute part AT04-4P-SR01GRY meets all mandatory parameters and differs only in housing color (Gray versus Red), making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both AT04-4P-SR01RED and AT04-4P-SR01GRY maintain Active product status and carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Both parts are manufactured by Amphenol Sine Systems Corp within the ATSeries™SR01 product line.

Selection between these parts should be based on:

1. Color Requirement: If housing color is specified in the application design or assembly documentation, select the corresponding part number. If color is not a functional requirement, either part is electrically and mechanically equivalent.

2. Inventory Availability: AT04-4P-SR01GRY currently maintains higher inventory levels (1094 units) compared to AT04-4P-SR01RED (759 units), which may influence procurement lead time considerations.

3. Compliance Alignment: Both parts satisfy identical regulatory requirements and are suitable for applications requiring IP68/IP69K sealed connectors with operating temperatures from -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can AT04-4P-SR01GRY be used as a direct replacement for AT04-4P-SR01RED?

A: Yes. The AT04-4P-SR01GRY is a direct functional equivalent. Both parts share identical electrical specifications, mechanical dimensions, mounting characteristics, and performance ratings. The only difference is housing color (Gray versus Red).

Q: Are there any electrical performance differences between the red and gray variants?

A: No. Both variants are manufactured to identical electrical specifications, including contact type, termination method, and operating temperature range. Housing color does not affect electrical performance.

Q: What does the base product number AT04-4P indicate?

A: The base product number AT04-4P identifies the core connector housing design with 4 positions in 2 rows. The suffix "-SR01RED" or "-SR01GRY" specifies the series variant and color option.

Q: Are contacts included with these connector housings?

A: The AT04-4P-SR01RED includes contacts as part of the standard assembly. The AT04-4P-SR01GRY is supplied as a housing only, with contacts not included. Verify contact requirements when selecting between these variants.

Q: What sealing ratings do these connectors provide?

A: Both connectors meet IP68 and IP69K sealing standards, providing protection against dust ingress and high-pressure water jets. The sealed design with strain relief ensures environmental protection in demanding applications.

Q: Can these connectors be used in temperature-critical applications?

A: Yes. Both variants operate across the temperature range of -55°C to 125°C, making them suitable for applications requiring extended thermal performance.

Q: What is the fastening mechanism for these connectors?

A: Both parts use a Latch Holder fastening type, providing secure mechanical connection without additional hardware.
