AT04-12PA Equivalent & Substitute Parts

Part Overview

The AT04-12PA is a 12-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This connector is designed for applications requiring crimp-terminated male pin contacts with free-hanging in-line mounting. The part is currently active in production with 11,619 units in stock.

Substitute parts are identified when equivalent rectangular connectors share the same functional specifications: 12-position capacity, receptacle configuration, male pin contact type, crimp termination, latch holder fastening, and identical operating temperature range. Substitutes become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements permit cross-manufacturer compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-12PA are qualified based on strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 12
• 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 substitute parts DT04-12PA and DT04-12PA-B016 meet all functional equivalence criteria. Both are manufactured by TE Connectivity Deutsch Connectors and maintain identical electrical and mechanical specifications to the AT04-12PA. The primary distinction between substitutes is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

AT04-12PA (Primary Part): The AT04-12PA is the recommended selection for new designs and applications. This part maintains active production status with robust inventory availability (11,619 units). Full ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for industrial and commercial applications.

DT04-12PA-B016 (Preferred Substitute): The DT04-12PA-B016 is the primary substitute option. This part is currently active in production with adequate inventory (5,198 units) and identical functional specifications to the AT04-12PA. Bulk packaging matches the primary part configuration. Selection of this substitute is appropriate when AT04-12PA availability is constrained or when design flexibility permits cross-manufacturer sourcing.

DT04-12PA (Secondary Substitute): The DT04-12PA is functionally equivalent but carries discontinued status at DiGi Electronics. This part should be selected only when inventory from alternative distribution channels is confirmed available and when design timelines permit extended lead time procurement. The reduced inventory level (2,100 units) indicates limited availability.

All three parts satisfy identical compliance requirements (ROHS3, REACH Unaffected) and operate within the same temperature specification (-55°C ~ 125°C).

Frequently Asked Questions (FAQ)

Q: Can DT04-12PA and DT04-12PA-B016 be used interchangeably with AT04-12PA?

A: Yes. Both DT04-12PA and DT04-12PA-B016 are functionally equivalent to AT04-12PA across all critical parameters: 12-position receptacle configuration, male pin contacts, crimp termination, latch holder fastening, and identical operating temperature range. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference between DT04-12PA and DT04-12PA-B016?

A: Both parts are manufactured by TE Connectivity Deutsch Connectors and share identical electrical and mechanical specifications. The primary differences are: DT04-12PA is discontinued at DiGi Electronics with 2,100 units in stock, while DT04-12PA-B016 is active in production with 5,198 units in stock. DT04-12PA-B016 specifies bulk packaging, matching the AT04-12PA configuration.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist when substituting between AT04-12PA, DT04-12PA, and DT04-12PA-B016. All three parts maintain identical connector type, contact configuration, position count, mounting method, and termination approach. Mating connectors and contact pins designed for one part are compatible with all three.

Q: What is the significance of the "-B016" suffix in DT04-12PA-B016?

A: The "-B016" suffix indicates a specific packaging or configuration variant within the DT04-12PA product line. This variant is specified as bulk packaging, consistent with the AT04-12PA packaging designation.

Q: Which substitute should be selected for new production designs?

A: DT04-12PA-B016 is the recommended substitute for new production designs. This part is active in production, maintains adequate inventory levels, and carries identical specifications to the AT04-12PA. The active status ensures long-term availability and supply chain stability.

Q: Are all three parts suitable for applications requiring ROHS3 compliance?

A: Yes. AT04-12PA, DT04-12PA, and DT04-12PA-B016 are all ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for applications in regulated industries and markets requiring environmental compliance certification.
