AT04-4P-SR01BLU Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR01BLU 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 with full ROHS3 compliance. The housing features a blue thermoplastic body with integrated strain relief, latch holder fastening, and sealed design rated for IP68 and IP69K protection standards.

Substitute parts are identified when alternative connector housings maintain identical electrical and mechanical specifications while differing only in non-functional attributes such as color. This allows for component interchangeability in applications where housing color does not impact circuit performance or system requirements.

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-SR01BLU are identified based on strict equivalence across all functional and mechanical parameters. The substitution logic is based on the following criteria:

Critical Matching Parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Number of rows (2)
• Contact type (Male Pin)
• Contact termination method (Crimp)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Latch Holder)
• Insulation material (Thermoplastic)
• Operating temperature range (-55°C ~ 125°C)
• Protection ratings (IP68, IP69K)
• Series designation (ATSeries™SR01)
• Base product number (AT04-4P)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

Non-Functional Differentiators:

• Housing color (Blue vs. Gray)

Parts that maintain identical specifications across all critical parameters are classified as parametric equivalents. Color variation alone does not affect electrical performance, mechanical fit, or environmental protection characteristics and therefore does not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-SR01BLU and AT04-4P-SR01GRY are active products with identical regulatory compliance certifications. Selection between these parts should be based on application-specific requirements:

AT04-4P-SR01BLU (Blue Housing): Select this part when system design specifications, wiring harness color-coding standards, or visual identification protocols require blue connector housings. Current inventory: 924 pieces.

AT04-4P-SR01GRY (Gray Housing): Select this part when system design specifications, wiring harness color-coding standards, or visual identification protocols require gray connector housings. Current inventory: 1094 pieces. Note that contacts are not included with this part number.

Both parts maintain full compliance with ROHS3 regulations and REACH directives. Both are classified under ECCN EAR99 and HTSUS code 8538.90.6000. The identical operating temperature range (-55°C ~ 125°C), protection ratings (IP68, IP69K), and mechanical specifications ensure functional interchangeability in all electrical and environmental applications.

Frequently Asked Questions (FAQ)

Q: Can AT04-4P-SR01GRY be used as a direct replacement for AT04-4P-SR01BLU?

A: Yes. Both parts are parametric equivalents with identical electrical, mechanical, and environmental specifications. The only difference is housing color. Substitution is valid when color is not a functional requirement.

Q: Are there any compatibility issues between the blue and gray versions?

A: No. Both versions use identical connector geometry, contact types, termination methods, and mounting configurations. They are fully compatible with the same mating connectors and contact sets.

Q: What is the difference in the number of rows between these parts?

A: Both parts have 2 rows of positions. There is no difference in row configuration.

Q: Do both parts include contacts?

A: The AT04-4P-SR01BLU specification indicates contacts are included as part of the housing assembly. The AT04-4P-SR01GRY specification explicitly notes that contacts are not included. Verify contact requirements for your application.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical range of -55°C to 125°C. There are no temperature-related limitations that would prevent substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both AT04-4P-SR01BLU and AT04-4P-SR01GRY are ROHS3 compliant and REACH unaffected. Both are classified under ECCN EAR99.

Q: What mounting configuration do these connectors use?

A: Both parts use free hanging in-line mounting with latch holder fastening. They are designed for crimp-style contact termination.

Q: What protection ratings do these connectors provide?

A: Both parts are sealed with IP68 and IP69K protection ratings. Both include integrated strain relief and protective caps.
