AT04-12PC-MM01 Equivalent & Substitute Parts

Part Overview

The AT04-12PC-MM01 is a 12-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 RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative manufacturer selection.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by alignment across the following critical parameters:

Connector Type & Contact Configuration: Both the main part and substitute must function as receptacles with male pin contacts
Position Count & Row Configuration: 12-position, 2-row arrangement must be maintained
Mounting & Termination Method: Free-hanging, in-line mounting with crimp termination is required
Fastening Mechanism: Latch holder fastening type must be preserved
Environmental Specifications: Operating temperature range of -55°C to 125°C must be supported
Regulatory Compliance: RoHS3 compliance is mandatory

The DT04-12PC-CE07 manufactured by TE Connectivity Deutsch Connectors satisfies all substitution criteria. This part maintains identical core electrical and mechanical specifications while offering enhanced features including IP68/IP6K9K sealing ratings and advanced keying mechanisms.

Engineering Selection Recommendations

Both the AT04-12PC-MM01 and DT04-12PC-CE07 are active production parts with full RoHS3 compliance, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on the following factors:

AT04-12PC-MM01 (Amphenol Sine Systems Corp): Select this part when standard sealed receptacle housing functionality is required. The part carries MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

DT04-12PC-CE07 (TE Connectivity Deutsch Connectors): Select this part when enhanced environmental protection is required. This substitute provides IP68 and IP6K9K sealing ratings, advanced keying features, and reduced wire seals. The polyamide glass-filled insulation material offers improved mechanical properties compared to standard thermoplastic construction.

Both parts are suitable for direct substitution in applications where the core 12-position, 2-row receptacle housing with crimp termination and latch fastening is specified. Inventory availability differs between manufacturers, with TE Connectivity currently maintaining higher stock levels (1131 pcs vs. 719 pcs).

Frequently Asked Questions (FAQ)

Q: Can DT04-12PC-CE07 be used as a direct replacement for AT04-12PC-MM01?

A: Yes. Both parts share identical core specifications: 12-position receptacle housing, 2-row configuration, male pin contacts, crimp termination, latch holder fastening, and -55°C to 125°C operating range. The DT04-12PC-CE07 includes additional features (IP68/IP6K9K sealing, enhanced keying) that do not prevent compatibility with applications designed for the AT04-12PC-MM01.

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

A: The AT04-12PC-MM01 uses thermoplastic insulation material. The DT04-12PC-CE07 uses polyamide (PA) nylon with glass filling. Glass-filled polyamide provides enhanced mechanical strength and thermal stability, making it suitable for more demanding environmental conditions.

Q: Are there differences in moisture sensitivity handling?

A: The AT04-12PC-MM01 carries MSL 1 (unlimited), indicating no moisture sensitivity constraints. The DT04-12PC-CE07 lists MSL as Not Applicable, reflecting its enhanced sealing design (IP68/IP6K9K) that eliminates moisture sensitivity concerns through superior environmental protection.

Q: Do both parts require separate contact purchases?

A: Yes. Both the AT04-12PC-MM01 and DT04-12PC-CE07 are housing-only components. Contacts are not included and must be sourced separately according to your wire gauge and termination requirements (14-20 AWG for the AT04-12PC-MM01).

Q: What are the regulatory compliance differences?

A: Both parts are RoHS3 compliant and carry EAR99 ECCN classification. The AT04-12PC-MM01 is REACH Unaffected. The DT04-12PC-CE07 lists REACH status as Vendor Undefined. Both parts meet current regulatory requirements for industrial and commercial applications.

Q: Can these parts be intermixed in the same connector assembly?

A: These are housing components only. Compatibility depends on contact specifications and mating connector design. Verify that mating plugs are compatible with both the AT Series™ and DT Series connector families before intermixing in production assemblies.
