AT04-4P-SR01YEL Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR01YEL is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the ATSeries™SR01 product line and is classified as an active product. The housing features a yellow thermoplastic body with integrated strain relief, sealed design rated to IP68 and IP69K standards, and a latch holder fastening mechanism. This connector is designed for free-hanging in-line mounting applications requiring crimp-type contact termination.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications where alternative housing colors or inventory availability necessitate component substitution while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-SR01YEL are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 4
• Number of Rows: 2
• Contact Type: Male Pin
• Contact Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Latch Holder
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Features: Cap (Cover), IP68, IP69K, Sealed, Strain Relief
• Series: ATSeries™SR01
• Base Product Number: AT04-4P
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameters (Non-Critical for Substitution):

• Housing Color (Yellow vs. Gray)

Parts meeting all mandatory parameter requirements are classified as direct substitutes. Housing color variation does not affect electrical or mechanical compatibility and is therefore permitted as a substitution variable.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-SR01YEL and AT04-4P-SR01GRY maintain active product status within the ATSeries™SR01 line, ensuring continued manufacturer support and availability. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on application-specific requirements:

AT04-4P-SR01YEL (Yellow Housing): Select this part when yellow housing color is specified in design documentation, assembly procedures, or visual identification protocols.

AT04-4P-SR01GRY (Gray Housing): Select this part when gray housing color is required or when yellow housing is unavailable. This substitute provides identical electrical and mechanical performance.

Both parts are suitable for applications requiring sealed, weatherproof connections across the -55°C to 125°C operating temperature range with IP68 and IP69K environmental protection ratings.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-SR01YEL and AT04-4P-SR01GRY electrically interchangeable?

A: Yes. Both parts are electrically identical. They share the same connector type, contact configuration, termination method, and operating specifications. Housing color does not affect electrical performance or signal integrity.

Q: Can I substitute AT04-4P-SR01GRY for AT04-4P-SR01YEL in an existing assembly?

A: Yes, provided that housing color is not a functional or identification requirement in your application. Both parts maintain identical mechanical fit, mating characteristics, and environmental sealing performance.

Q: Do these parts require the same contact pins and accessories?

A: Both housings are compatible with the same crimp-type male pin contacts designed for the ATSeries™SR01 line. Verify contact specifications separately, as housing and contacts are typically ordered as separate components.

Q: What is the difference between these two parts?

A: The only difference is housing color. AT04-4P-SR01YEL features a yellow thermoplastic housing, while AT04-4P-SR01GRY features a gray thermoplastic housing. All other specifications, including connector type, position count, row configuration, fastening mechanism, environmental ratings, and operating temperature range, are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both AT04-4P-SR01YEL and AT04-4P-SR01GRY are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for use in regulated markets and applications.

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

A: Both parts operate across -55°C to 125°C, supporting applications in extreme thermal environments including automotive, industrial, and outdoor installations.

Q: Do these housings include protective caps?

A: Yes. Both AT04-4P-SR01YEL and AT04-4P-SR01GRY include integrated protective caps (covers) as part of the standard housing design, providing additional environmental protection when connectors are unmated.
