AT04-3P-ORG Equivalent & Substitute Parts

Part Overview

The AT04-3P-ORG is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp in the AT Series™. This component is a sealed, free-hanging connector housing designed for crimp termination with male pin contacts. The part is currently Active in product status and is ROHS3 compliant. Substitute parts are necessary when specific color coding requirements differ from the orange housing of the primary part, while maintaining identical electrical and mechanical specifications across the connector family.

Substitute Part Grouping Explanation

All substitute parts for the AT04-3P-ORG are derived from the same base product number AT04-3P and share identical electrical and mechanical specifications. Substitution is determined by the following key parameters that remain constant across all variants:

Connector Type: Receptacle
Contact Type: Male Pin
Number of Positions: 3
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

The only variable parameter across the substitute family is the housing color. All parts within this family are functionally and mechanically interchangeable, with color serving as the sole differentiator for circuit identification and wiring harness organization purposes.

Engineering Selection Recommendations

All substitute parts listed are Active products with ROHS3 compliance and REACH Unaffected status, meeting the same regulatory and environmental standards as the primary AT04-3P-ORG part. Selection among the substitute family should be based on color-coding requirements for circuit identification and harness organization within the application.

The AT04-3P-GRN variant currently maintains the highest inventory level at 1776 pieces, followed by AT04-3P-RED at 1614 pieces. The AT04-3P-BRN variant is available with 887 pieces in stock. All parts are packaged in boxes and are suitable for immediate deployment in production environments.

Contacts are not included with any housing variant and must be sourced separately according to application requirements.

Frequently Asked Questions (FAQ)

Q: Are all AT04-3P color variants electrically identical?

A: Yes. All variants within the AT04-3P family share identical electrical specifications, including connector type, contact configuration, termination method, and operating temperature range. Color is the only differentiating parameter.

Q: Can I substitute AT04-3P-ORG with AT04-3P-BLU in my application?

A: Substitution is valid from an electrical and mechanical standpoint. Both parts are receptacle housings with 3 positions, 2 rows, crimp termination, and sealed construction. Color substitution is acceptable if circuit identification requirements permit the change.

Q: What is the operating temperature range for all AT04-3P variants?

A: All variants operate across the temperature range of -55°C to 125°C, supporting applications in both industrial and automotive environments.

Q: Are contacts included with the AT04-3P-ORG housing?

A: No. All AT04-3P housing variants are supplied without contacts. Contacts must be procured separately and crimped into the housing according to application specifications.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: All AT04-3P variants carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are all AT04-3P variants ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between the base product number AT04-3P and the full part numbers like AT04-3P-ORG?

A: The base product number AT04-3P identifies the core connector family. The suffix (such as -ORG, -BLU, -GRN) designates the housing color variant. All variants share the same base specifications.

Q: Can I use AT04-3P-BRN as a direct replacement for AT04-3P-ORG?

A: From a functional and mechanical perspective, yes. Both are 3-position receptacle housings with identical electrical characteristics. The substitution is valid if your application does not require specific color coding.
