Substitute Part Grouping Explanation

Substitute parts for the AT04-2P-SR02BLU are determined by equivalence across all electrical and mechanical parameters while permitting variation in housing color. The substitution logic is based on the following criteria:

Substitution-Determining Parameters:

• Manufacturer: Amphenol Sine Systems Corp
• Series: ATSeries™SR02
• Base Product Number: AT04-2P
• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 2
• Number of Rows: 1
• 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
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter:

• Housing Color: Blue (primary), Gray (substitute), Red (substitute)

All substitute parts maintain identical functional and environmental specifications. Housing color selection is determined by application requirements, visual identification needs, or inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AT04-2P-SR02BLU, AT04-2P-SR02GRY, and AT04-2P-SR02RED—are functionally equivalent rectangular connector receptacles within the ATSeries™SR02 product line. Each part maintains Active product status and full ROHS3 compliance with REACH Unaffected designation.

Selection between these parts is based on housing color requirements:

AT04-2P-SR02BLU (Blue Housing): Primary specification with 1084 units in stock. Use when blue color identification or circuit board color matching is required.

AT04-2P-SR02GRY (Gray Housing): Parametric equivalent with 1565 units in stock. Use when gray color identification is specified or when maximum inventory availability is prioritized.

AT04-2P-SR02RED (Red Housing): Parametric equivalent with 1160 units in stock. Use when red color identification or visual distinction is required for application-specific purposes.

All parts support identical electrical performance across the -55°C to 125°C operating temperature range and deliver equivalent environmental protection through IP68 and IP69K ratings. Contact termination, mounting configuration, and fastening mechanisms are identical across all three variants.

Frequently Asked Questions (FAQ)

Q: Are AT04-2P-SR02BLU, AT04-2P-SR02GRY, and AT04-2P-SR02RED electrically interchangeable?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical connector type, contact configuration, number of positions, termination method, and operating specifications. The only difference is housing color.

Q: What determines whether I should use the blue, gray, or red variant?

A: Housing color selection is application-dependent. Use blue when the original specification calls for blue color identification. Use gray or red when alternative color identification is acceptable or when color-coded circuit organization is required. Color selection does not affect electrical performance or environmental ratings.

Q: Are all three parts ROHS3 compliant?

A: Yes. AT04-2P-SR02BLU, AT04-2P-SR02GRY, and AT04-2P-SR02RED are all ROHS3 compliant with REACH Unaffected status.

Q: Can I substitute one color variant for another in an existing assembly?

A: Substitution is permissible from an electrical and mechanical standpoint. However, verify that color-coding requirements or visual identification schemes in your assembly documentation do not restrict color selection.

Q: What is the operating temperature range for these connectors?

A: All three variants operate across -55°C to 125°C. This range applies to all substitute parts without variation.

Q: Do these connectors include contacts?

A: The AT04-2P-SR02BLU and AT04-2P-SR02RED include contacts. The AT04-2P-SR02GRY is specified as a housing without contacts included. Verify contact inclusion requirements before ordering.

Q: What environmental protection do these connectors provide?

A: All three parts feature IP68 and IP69K ratings, indicating protection against dust ingress and high-pressure water jets. Reduced wire seals and strain relief are included on all variants.

Q: Are these parts suitable for free-hanging applications?

A: Yes. All three parts are rated for free-hanging, in-line mounting. Latch holder fastening is standard across all variants.
