AT04-3P-MM01 Equivalent & Substitute Parts

Part Overview

The AT04-3P-MM01 is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the AT Series™ product line and is classified as an active product with full availability. The connector is designed for applications requiring free-hanging, in-line mounting with crimp termination and latch holder fastening. Substitute parts are identified when inventory constraints, lead time requirements, or specific application needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-3P-MM01 is determined by strict alignment of the following critical parameters:

Mandatory Matching 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
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Compliance: ROHS3 Compliant
• REACH Status: REACH Unaffected

The DT04-3P-CE01 manufactured by TE Connectivity Deutsch Connectors satisfies all mandatory matching parameters and is therefore classified as a direct substitute. Both components are receptacle housings with identical position counts, row configurations, mounting methods, and termination specifications. Both operate across the same temperature range and meet equivalent regulatory compliance standards.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-3P-MM01 and DT04-3P-CE01 are active products with full regulatory compliance under ROHS3 and REACH standards. Selection between these components is based on application-specific requirements and availability considerations.

The AT04-3P-MM01 features thermoplastic insulation material with sealed design characteristics. The DT04-3P-CE01 features polyamide (PA66) nylon 6/6 glass-filled insulation with enhanced environmental protection ratings (IP68, IP6K9K) and reduced wire seals. The DT04-3P-CE01 is suitable for applications requiring higher ingress protection ratings and superior chemical resistance. The AT04-3P-MM01 is suitable for standard sealed applications where thermoplastic insulation meets performance requirements.

Both components share identical electrical and mechanical specifications for connector type, position count, row configuration, mounting method, termination type, and fastening mechanism. Both operate across the full -55°C to 125°C temperature range and meet equivalent regulatory compliance standards.

Frequently Asked Questions (FAQ)

Q: What makes the DT04-3P-CE01 a valid substitute for the AT04-3P-MM01?

A: The DT04-3P-CE01 matches all critical electrical and mechanical parameters of the AT04-3P-MM01, including connector type (receptacle), contact type (male pin), position count (3), row configuration (2), mounting method (free hanging in-line), termination type (crimp), fastening mechanism (latch holder), and operating temperature range (-55°C to 125°C). Both components are ROHS3 compliant and REACH unaffected.

Q: Are there differences in material composition between these parts?

A: Yes. The AT04-3P-MM01 uses thermoplastic insulation material, while the DT04-3P-CE01 uses polyamide (PA66) nylon 6/6 glass-filled insulation. The DT04-3P-CE01 also includes enhanced environmental protection features (IP68, IP6K9K ratings) and reduced wire seals. These material and feature differences do not affect substitution eligibility when electrical and mechanical parameters are identical.

Q: Do these connectors require contacts to be purchased separately?

A: Yes. Both the AT04-3P-MM01 and DT04-3P-CE01 are connector housings supplied without contacts. Contacts must be sourced and crimped separately according to application requirements.

Q: Are both parts available in the same packaging format?

A: Both components are supplied in bulk packaging. The AT04-3P-MM01 has 1203 pieces in stock, and the DT04-3P-CE01 has 2437 pieces in stock.

Q: What is the difference between the sealed design and IP68/IP6K9K ratings?

A: The AT04-3P-MM01 features a sealed design with cap (cover). The DT04-3P-CE01 features a sealed design with cap (cover) plus IP68 and IP6K9K environmental protection ratings. IP68 indicates protection against continuous immersion in water beyond 1 meter depth. IP6K9K indicates protection against high-pressure water jets. These enhanced ratings provide superior environmental protection in demanding applications.

Q: Can these parts be used interchangeably in existing designs?

A: Substitution is valid when the application requirements align with the specified electrical and mechanical parameters. Both components share identical connector type, position count, row configuration, mounting method, termination type, and fastening mechanism. Material and feature differences must be evaluated against specific application environmental and performance requirements.
