AT04-4P-SR02YEL Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR02YEL is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the ATSeries™SR02 product line and is classified as an active product. The yellow housing variant is designed for applications requiring free-hanging, in-line mounting with crimp contact termination. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative housing colors or inventory considerations necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-SR02YEL are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector type (Receptacle)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (2)
• Mounting type (Free Hanging, In-Line)
• Contact termination method (Crimp)
• Fastening type (Latch Holder)
• Operating temperature range (-55°C ~ 125°C)
• Feature set (Cap/Cover, IP68, IP69K, Reduced Wire Seals, Strain Relief)
• Insulation material (Thermoplastic)
• Series designation (ATSeries™SR02)
• Base product number (AT04-4P)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

Variations in housing color alone do not affect functional or electrical compatibility. The AT04-4P-SR02GRY substitute maintains all specified parameters while offering an alternative gray housing option.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-SR02YEL and AT04-4P-SR02GRY are active products with identical regulatory compliance certifications. Selection between these parts is determined by application-specific requirements for housing color identification or visual coding standards. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental regulations. The gray variant (AT04-4P-SR02GRY) currently maintains higher inventory availability at 1482 pieces compared to 1113 pieces for the yellow variant. Component selection should be based on documented color-coding requirements within the system design or application specification.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-SR02YEL and AT04-4P-SR02GRY electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications, including connector type, contact configuration, termination method, and operating temperature range. The housing color difference does not affect electrical performance or signal integrity.

Q: What is the primary difference between these substitute parts?

A: The primary difference is housing color. The AT04-4P-SR02YEL features a yellow housing, while the AT04-4P-SR02GRY features a gray housing. All other mechanical and electrical parameters are equivalent.

Q: Can I use AT04-4P-SR02GRY as a direct replacement for AT04-4P-SR02YEL in existing assemblies?

A: Direct replacement is possible from an electrical and mechanical standpoint. However, if the application requires specific color coding for identification, traceability, or visual system organization, the color difference must be evaluated against application requirements.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both AT04-4P-SR02YEL and AT04-4P-SR02GRY are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: What mounting configuration do these connectors support?

A: Both parts support free-hanging, in-line mounting with crimp contact termination and latch holder fastening. The thermoplastic insulation material and strain relief features provide mechanical stability in this configuration.

Q: Do these connectors include contacts?

A: The AT04-4P-SR02YEL includes contacts as part of the standard package. The AT04-4P-SR02GRY is supplied as a housing without contacts included, requiring separate contact procurement.

Q: What environmental protection ratings do these connectors provide?

A: Both parts feature IP68 and IP69K ratings, indicating protection against dust ingress and high-pressure water jets. Reduced wire seals and strain relief features enhance environmental sealing performance.
