AT04-08PC-MM01 Equivalent & Substitute Parts

Part Overview

The AT04-08PC-MM01 is an 8-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component belongs to the AT Series™ product line and is designed for applications requiring free-hanging, in-line connectivity with crimp termination. The part is actively produced and maintains full inventory availability with 978 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain continuity, or application-specific feature requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-08PC-MM01 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Connector Type: Receptacle
Contact Type: Male Pin
Number of Positions: 8
Number of Rows: 2
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Fastening Type: Latch Holder
Operating Temperature Range: -55°C ~ 125°C

Allowable Variations:

Insulation Material: Thermoplastic or Plastic
Features: Additional sealing or protection features (Cap/Cover, IP ratings, wire seals) do not disqualify substitution
Manufacturer: Different manufacturers permitted if all mandatory parameters align
Inventory Status: Substitute availability independent of main part stock levels

The DT04-08PC-CE01 manufactured by TE Connectivity Deutsch Connectors meets all mandatory parameter requirements and qualifies as a direct substitute for the AT04-08PC-MM01.

Engineering Selection Recommendations

Both the AT04-08PC-MM01 and DT04-08PC-CE01 are active products with full regulatory compliance. Selection between these rectangular connector housings should be based on the following factors:

AT04-08PC-MM01 (Amphenol Sine Systems Corp):

Primary choice when Amphenol component standardization is required
Suitable for applications with standard sealing requirements
Current inventory: 978 units

DT04-08PC-CE01 (TE Connectivity Deutsch Connectors):

Primary choice when enhanced environmental protection is required (IP68, IP6K9K ratings)
Suitable for applications requiring reduced wire seals
Current inventory: 1,294 units
Recommended when supply chain continuity for Amphenol parts is constrained

Both parts satisfy ROHS3 and REACH compliance requirements. The DT04-08PC-CE01 provides additional environmental sealing features without compromising core electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DT04-08PC-CE01 be used as a direct replacement for the AT04-08PC-MM01?

A: Yes. Both parts are 8-position rectangular connector receptacles with identical core specifications: 2-row configuration, crimp termination, latch holder fastening, free-hanging mounting, and -55°C to 125°C operating temperature range. The DT04-08PC-CE01 includes additional IP68 and IP6K9K environmental protection features.

Q: What is the difference in insulation material between these parts?

A: The AT04-08PC-MM01 uses thermoplastic insulation, while the DT04-08PC-CE01 uses plastic insulation. Both materials are compatible with the specified operating temperature range and provide equivalent electrical performance for this connector category.

Q: Are contacts included with these connector housings?

A: No. Both the AT04-08PC-MM01 and DT04-08PC-CE01 are receptacle housings only. Contacts must be sourced separately and are not included with these parts.

Q: What does "Contacts Not Included" mean for connector selection?

A: The part number specifies the housing assembly only. Male pin contacts compatible with 14-20 AWG wire gauge must be procured separately and crimped into the housing during assembly.

Q: Are there any restrictions on mixing these parts in the same application?

A: No restrictions exist. Both parts meet identical electrical and mechanical requirements. They can be used interchangeably within the same system or assembly.

Q: What is the significance of the IP68 and IP6K9K ratings on the DT04-08PC-CE01?

A: IP68 indicates protection against continuous immersion in water. IP6K9K indicates protection against high-pressure water jets. These ratings provide enhanced environmental sealing compared to the standard sealed design of the AT04-08PC-MM01.

Q: How do the base product numbers relate to these parts?

A: The AT04-08PC-MM01 has base product number AT04-08PC. The DT04-08PC-CE01 has base product number DT04. Base product numbers identify the core connector family; the full part number includes packaging and configuration variants.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the AT04-08PC-MM01 and DT04-08PC-CE01 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
