AT04-3P-RED Equivalent & Substitute Parts

Part Overview

The AT04-3P-RED is a 3-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 with full product availability (1614 pieces in stock). Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative color designations are necessary for circuit identification, inventory management, or application-specific wiring standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-3P-RED are determined by equivalence across all electrical and mechanical parameters while varying only in color designation. The substitution logic is based on the following criteria:

Substitution-Determining Parameters:

• 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
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Features: Sealed
• Base Product Number: AT04-3P

All substitute parts maintain identical electrical and mechanical specifications. The only variable parameter is color, which serves as a visual identifier for circuit tracing, wiring standards compliance, or inventory organization. All substitute parts share the same base product number (AT04-3P) and are manufactured by Amphenol Sine Systems Corp within the AT Series™ line.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed (AT04-3P-BLU, AT04-3P-GRN, AT04-3P-ORG, AT04-3P-YEL) are Active products with full compliance to ROHS3 and REACH standards. Each part maintains identical electrical and mechanical specifications to the AT04-3P-RED, differing only in color designation.

Selection between equivalent parts should be based on:

1. Circuit Identification Requirements: Color coding serves as a visual identifier for circuit tracing and wiring organization within assemblies.

2. Inventory Availability: Current stock levels vary across color variants. AT04-3P-GRN maintains the highest inventory (1776 pieces), while AT04-3P-ORG maintains the lowest (792 pieces).

3. Application Standards: Specific industries or internal standards may mandate particular color assignments for signal types or circuit functions.

4. Compliance Verification: All substitute parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1), ensuring regulatory equivalence across all color variants.

Frequently Asked Questions (FAQ)

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

A: Yes. All AT04-3P variants (RED, BLU, GRN, ORG, YEL) maintain identical electrical specifications including connector type, contact configuration, termination method, operating temperature range, and sealed features. Color is the only differentiating parameter.

Q: Can I substitute AT04-3P-RED with AT04-3P-BLU in my assembly?

A: Substitution is valid from an electrical and mechanical standpoint. The parts are functionally equivalent. Substitution decisions should account for color-coding requirements in your circuit design or assembly documentation.

Q: What is the significance of the base product number AT04-3P?

A: The base product number AT04-3P identifies the core connector housing design shared across all color variants. The suffix (RED, BLU, GRN, ORG, YEL) designates the color variant only.

Q: Are contacts included with these receptacle housings?

A: No. All AT04-3P receptacle housings are supplied without contacts. Male pin contacts must be sourced separately and crimped into the housing according to Amphenol specifications.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts have unlimited shelf life and do not require special moisture-controlled storage conditions.

Q: Are all color variants ROHS3 compliant?

A: Yes. All AT04-3P color variants (RED, BLU, GRN, ORG, YEL) are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between a receptacle and a plug connector?

A: The AT04-3P-RED is a receptacle housing designed to accept male pin contacts. It is the female component of a connector pair. The mating plug connector would be a separate component designed to interface with this receptacle.

Q: Can I use these connectors in high-temperature applications?

A: Yes. All AT04-3P variants are rated for continuous operation across the temperature range of -55°C to 125°C, suitable for industrial and automotive applications within this thermal envelope.
