AT04-12PC Equivalent & Substitute Parts

Part Overview

The AT04-12PC is a 12-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This connector is designed for applications requiring free-hanging, in-line mounting with crimp termination and latch holder fastening. The part is currently active in production with 1,158 units in stock.

Substitute parts are identified when equivalent rectangular connectors share the same critical functional parameters: 12-position capacity, receptacle configuration, male pin contact type, 2-row arrangement, free-hanging mounting, crimp termination, and latch holder fastening. Substitutes maintain compatibility across the operating temperature range of -55°C to 125°C and comply with equivalent regulatory standards.

Substitute Part Grouping Explanation

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

Connector Configuration: Receptacle housing with 12 positions arranged in 2 rows
Contact Interface: Male pin contact type for mating compatibility
Termination Method: Crimp contact termination
Mechanical Fastening: Latch holder fastening mechanism
Installation Format: Free-hanging, in-line mounting orientation
Thermal Performance: Operating temperature range of -55°C to 125°C
Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute parts DT04-12PC and DT04-12PC-B016, both manufactured by TE Connectivity Deutsch Connectors, meet all these equivalence criteria. Both parts are active products with confirmed inventory availability.

Engineering Selection Recommendations

Both DT04-12PC and DT04-12PC-B016 are qualified substitutes for the AT04-12PC based on functional equivalence across all critical parameters. Selection between these options is determined by application-specific requirements and inventory considerations.

DT04-12PC is suitable for applications requiring enhanced environmental protection, as this variant includes IP68 and IP6K9K ratings. The insulation material is specified as polyamide (PA) nylon with glass filling, providing increased mechanical durability. This part carries ROHS3 compliance and REACH unaffected status with 4,073 units currently in stock.

DT04-12PC-B016 provides an alternative TE Connectivity option with equivalent functional parameters. The insulation material is specified as plastic. This variant maintains ROHS3 compliance, MSL rating of 1 (Unlimited), and REACH unaffected status with 1,310 units in stock.

Both substitute parts maintain the same operating temperature range, termination method, and fastening mechanism as the original AT04-12PC. All three parts are active products with confirmed availability.

Frequently Asked Questions (FAQ)

Q: What makes DT04-12PC and DT04-12PC-B016 equivalent to AT04-12PC?

A: Both substitute parts share the same critical functional parameters: 12-position receptacle configuration, male pin contacts, 2-row arrangement, free-hanging mounting, crimp termination, latch holder fastening, and -55°C to 125°C operating temperature range. All three parts are ROHS3 compliant and REACH unaffected.

Q: Are there differences in insulation material between the substitute parts?

A: Yes. The AT04-12PC uses thermoplastic insulation. DT04-12PC uses polyamide (PA) nylon with glass filling. DT04-12PC-B016 uses plastic insulation. These material differences do not affect functional equivalence for the specified operating parameters.

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

A: Both parts are functionally equivalent with identical connector specifications. DT04-12PC includes IP68 and IP6K9K environmental protection ratings and polyamide glass-filled insulation. DT04-12PC-B016 uses plastic insulation without the additional IP ratings. Both maintain the same operating temperature range and termination specifications.

Q: Do these connectors include contacts?

A: No. All three parts (AT04-12PC, DT04-12PC, and DT04-12PC-B016) are connector housings only. Contacts are not included and must be sourced separately.

Q: Can I use these parts interchangeably in my application?

A: Substitution is valid when the application requirements align with the specified parameters: 12-position capacity, receptacle configuration, male pin interface, crimp termination, and the -55°C to 125°C operating temperature range. The connector housings are mechanically and electrically compatible across all three part numbers.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: AT04-12PC and DT04-12PC-B016 both carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. DT04-12PC lists MSL as Not Applicable, which does not affect substitution eligibility for standard applications.
