AT04-4P-RED Equivalent & Substitute Parts
Part Overview
The AT04-4P-RED is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp as part of the AT Series™ product line. This component functions as a receptacle housing for male pin contacts in free-hanging, in-line configurations. The part is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative color options or inventory availability necessitate component selection from the AT04-4P base product family.

Substitute Part Grouping Explanation
Substitute parts for the AT04-4P-RED are determined by equivalence across all electrical and mechanical parameters while permitting variation in color designation only. The substitution logic is based on the following criteria:
Invariant Parameters (Must Match for Substitution):
- Base Product Number: AT04-4P
- Connector Type: Receptacle
- Contact Type: Male Pin
- Number of Positions: 4
- Number of Rows: 2
- Mounting Type: Free Hanging (In-Line)
- Contact Termination: Crimp
- Fastening Type: Latch Holder
- Features: Sealed
- Insulation Material: Thermoplastic
- Operating Temperature Range: -55°C ~ 125°C
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level: 1 (Unlimited)
- REACH Status: REACH Unaffected
- Product Status: Active
Variable Parameter (Permits Substitution Variation):
- Color: Red, Blue, Brown, Green, Orange
All substitute parts maintain identical functional and environmental specifications. Color selection is determined by application requirements, circuit identification standards, or inventory availability without affecting electrical or mechanical performance.

Engineering Selection Recommendations
All substitute parts listed—AT04-4P-BLU, AT04-4P-BRN, AT04-4P-GRN, and AT04-4P-ORG—maintain Active product status with identical compliance certifications. Each part carries ROHS3 compliance and REACH unaffected designation, ensuring regulatory equivalence across all variants.
Selection among substitute parts is determined by application-specific requirements including circuit identification color coding standards, system documentation specifications, or inventory availability. All variants support identical electrical performance, environmental operating ranges, and mechanical interface specifications.
The sealed housing design with thermoplastic insulation material and latch holder fastening provides consistent environmental protection across all color variants. Crimp contact termination and free-hanging in-line mounting configuration remain uniform across the product family.
Frequently Asked Questions (FAQ)
Q: Are all AT04-4P color variants electrically identical?
A: Yes. All substitute parts maintain identical electrical specifications, contact configurations, and operating parameters. Color designation is the only variable parameter and does not affect electrical performance or mechanical compatibility.
Q: Can AT04-4P-RED be directly replaced with AT04-4P-BLU in an existing assembly?
A: Yes, provided the application does not require specific color identification for circuit tracing or documentation purposes. All substitute parts share identical connector type, position count, row configuration, mounting method, and contact termination specifications.
Q: What is the significance of the base product number AT04-4P?
A: The base product number AT04-4P identifies the core connector housing design. All color variants (RED, BLU, BRN, GRN, ORG) are derived from this base design and share all mechanical and electrical characteristics except color.
Q: Are contacts included with these connector housings?
A: No. All AT04-4P variants are supplied as housings only. Male pin contacts must be sourced separately and installed via crimp termination.
Q: What is the operating temperature range for all AT04-4P variants?
A: All substitute parts operate across the range of -55°C to 125°C, providing consistent thermal performance across the product family.
Q: Do all variants carry the same regulatory compliance?
A: Yes. All AT04-4P color variants are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), ensuring equivalent regulatory status across all substitutes.
Q: What is the sealed feature in these connectors?
A: The sealed feature indicates environmental protection against moisture and contaminant ingress. This specification is uniform across all AT04-4P color variants.
