AT04-2P-SR02YEL Equivalent & Substitute Parts

Part Overview

The AT04-2P-SR02YEL is a 2-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 mounting applications. The housing features a yellow thermoplastic body with integrated strain relief, reduced wire seals, and IP68/IP69K environmental protection ratings.

The part maintains Active product status with full ROHS3 compliance and REACH unaffected classification. Substitute parts are necessary when application-specific requirements dictate alternative housing colors while maintaining identical electrical and mechanical specifications, or when inventory availability requires sourcing from equivalent alternatives within the same product series.

Substitute Part Grouping Explanation

Substitute parts for the AT04-2P-SR02YEL are determined by strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Mandatory Matching 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
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Features: Cap (Cover), IP68, IP69K, Reduced Wire Seals, Strain Relief
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Substitution Basis):

• Housing Color: Yellow (primary part) | Gray (substitute) | Red (substitute)

All substitute parts maintain identical form, fit, and function characteristics. Housing color variation does not affect electrical performance, mechanical compatibility, or environmental protection ratings. Substitutes are interchangeable at the connector housing level within the same assembly design.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AT04-2P-SR02YEL, AT04-2P-SR02GRY, and AT04-2P-SR02RED—are Active status products with full ROHS3 compliance and REACH unaffected classification. Each part is manufactured by Amphenol Sine Systems Corp and carries identical electrical and mechanical specifications.

Selection between these parts is determined by application-specific requirements for housing color identification or visual circuit board marking standards. The parts are functionally equivalent and interchangeable in any application where the AT04-2P-SR02 series 2-position receptacle housing is specified.

All substitute parts maintain the same environmental protection ratings (IP68, IP69K), operating temperature range (-55°C ~ 125°C), and mechanical features including strain relief and reduced wire seals. Compliance certifications are uniform across all three variants.

Frequently Asked Questions (FAQ)

Q: Are AT04-2P-SR02GRY and AT04-2P-SR02RED direct substitutes for AT04-2P-SR02YEL?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The only difference is housing color. All three parts share the same base product number (AT04-2P), series designation (ATSeries™SR02), connector type, contact configuration, mounting method, and environmental ratings.

Q: Does housing color affect connector performance or compatibility?

A: No. Housing color is a visual identification feature only. It does not impact electrical performance, mechanical fit, environmental protection ratings, or temperature operating range. All three variants provide identical IP68/IP69K protection and operate across the same -55°C ~ 125°C temperature range.

Q: Can I use AT04-2P-SR02GRY or AT04-2P-SR02RED in place of AT04-2P-SR02YEL in existing designs?

A: Yes, provided the application does not require specific color coding for circuit board identification or assembly documentation. The parts are mechanically and electrically interchangeable at the connector housing level.

Q: What is the difference between these parts and the base product number AT04-2P?

A: The base product number AT04-2P represents the core 2-position receptacle housing design. The suffix "-SR02" indicates the specific series variant. The final color designation (YEL, GRY, RED) specifies the housing color. All variants within this grouping share identical form, fit, and function.

Q: Are contacts included with these connector housings?

A: The AT04-2P-SR02YEL and AT04-2P-SR02RED are supplied as housings. The AT04-2P-SR02GRY is noted as "Contacts Not Included." Verify contact requirements separately when sourcing replacement parts.

Q: What certifications apply to all three substitute parts?

A: All three parts carry ROHS3 compliance and REACH unaffected status. Both certifications are uniform across AT04-2P-SR02YEL, AT04-2P-SR02GRY, and AT04-2P-SR02RED.

Q: Are these parts suitable for IP68 and IP69K rated applications?

A: Yes. All three parts feature integrated IP68 and IP69K environmental protection ratings, reduced wire seals, and strain relief. They are suitable for sealed connector applications requiring high-pressure water jet resistance.
