AT04-12PC-EC01 Equivalent & Substitute Parts

Part Overview

The AT04-12PC-EC01 is a 12-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This connector belongs to the AT Series™ product line and is designed for free-hanging, in-line applications requiring crimp termination with latch holder fastening. The part is actively produced and maintains full compliance with RoHS3 and REACH regulations. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative connector specifications from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-12PC-EC01 is determined by strict equivalence across the following critical parameters:

Connector Type: Must be Receptacle
Contact Type: Must be Male Pin
Number of Positions: Must be 12
Number of Rows: Must be 2
Mounting Type: Must be Free Hanging (In-Line)
Contact Termination: Must be Crimp
Fastening Type: Must be Latch Holder
Operating Temperature Range: Must support -55°C ~ 125°C
Regulatory Compliance: Must maintain RoHS3 and REACH compliance

The DT04-12PC-BE02 manufactured by TE Connectivity Deutsch Connectors satisfies all substitution criteria. Both parts share identical functional specifications for connector configuration, termination method, and environmental operating parameters. Variations in insulation material composition and additional features do not preclude substitution when electrical and mechanical interface requirements are met.

Engineering Selection Recommendations

Both the AT04-12PC-EC01 and DT04-12PC-BE02 are active production parts with full regulatory compliance. Selection between these parts should be based on:

AT04-12PC-EC01 (Amphenol Sine Systems Corp)

Primary choice when Amphenol AT Series™ ecosystem integration is required
Suitable for applications where thermoplastic insulation material is specified
Moisture Sensitivity Level 1 (Unlimited) provides maximum handling flexibility

DT04-12PC-BE02 (TE Connectivity Deutsch Connectors)

Alternative source when TE Connectivity supply chain is preferred
Enhanced keying and IP68/IP6K9K ratings provide additional environmental protection features
Glass-filled polyamide insulation offers enhanced mechanical durability
Appropriate for applications requiring higher ingress protection ratings

Both parts maintain identical electrical and mechanical interface specifications, ensuring direct substitution capability in applications where the core 12-position, 2-row receptacle housing with crimp termination is required.

Frequently Asked Questions (FAQ)

Q: Can DT04-12PC-BE02 be used as a direct replacement for AT04-12PC-EC01?

A: Yes. Both parts are 12-position receptacle housings with identical connector type, contact configuration, mounting method, and operating temperature range. The parts are electrically and mechanically interchangeable for applications requiring these specifications.

Q: What is the significance of the different insulation materials?

A: The AT04-12PC-EC01 uses thermoplastic insulation, while the DT04-12PC-BE02 uses glass-filled polyamide. Both materials satisfy the operating temperature range of -55°C ~ 125°C and maintain RoHS3 compliance. Material selection does not affect substitution eligibility when mechanical and electrical requirements are met.

Q: Does the DT04-12PC-BE02 include additional features that affect compatibility?

A: The DT04-12PC-BE02 includes enhanced keying, IP68, and IP6K9K ratings. These features provide additional environmental protection but do not compromise compatibility with applications designed for the AT04-12PC-EC01. Applications not requiring these enhanced features remain fully compatible.

Q: Are contacts included with either part?

A: No. Both the AT04-12PC-EC01 and DT04-12PC-BE02 are connector housings supplied without contacts. Contacts must be sourced separately and must be compatible with crimp termination specifications.

Q: What is the difference in Moisture Sensitivity Level between the parts?

A: The AT04-12PC-EC01 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The DT04-12PC-BE02 lists MSL as Not Applicable, indicating the part does not require moisture sensitivity classification. Both parts are suitable for standard handling and storage conditions.

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

A: Yes, provided the design does not specify manufacturer-specific requirements or require features unique to one supplier. The identical 12-position, 2-row configuration with crimp termination and latch holder fastening ensures mechanical and electrical compatibility.
