DT04-4P Equivalent & Substitute Parts

Part Overview

The DT04-4P is a 4-position rectangular connector housing manufactured by TE Connectivity Deutsch Connectors. This receptacle connector is designed for free-hanging, in-line applications with crimp termination and latch holder fastening. The part is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain functional compatibility for ongoing system support and new designs.

Substitute Part Grouping Explanation

Substitution of the DT04-4P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Connector Type: Receptacle
Contact Type: Male Pin
Number of Positions: 4
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

Identified Substitutes:

The AT04-4P (Amphenol Sine Systems Corp) and DTP10-4P (TE Connectivity Deutsch Connectors) satisfy all mandatory matching parameters. Both parts maintain identical functional specifications for connector configuration, termination method, and environmental operating conditions. The AT04-4P represents a cross-manufacturer alternative, while the DTP10-4P represents a same-manufacturer variant within the TE Connectivity Deutsch portfolio.

Engineering Selection Recommendations

AT04-4P Selection Criteria: The AT04-4P is an active product from Amphenol Sine Systems Corp with ROHS3 compliance and MSL 1 rating. This substitute provides cross-manufacturer compatibility while maintaining all functional parameters of the DT04-4P. Selection of the AT04-4P is appropriate for applications requiring immediate availability from an alternative supplier source.

DTP10-4P Selection Criteria: The DTP10-4P is an active product from TE Connectivity Deutsch Connectors with ROHS3 compliance. This substitute maintains same-manufacturer continuity within the TE Connectivity Deutsch portfolio. The primary distinction is housing color (black versus gray) and insulation material composition (PA46 versus PA). Selection of the DTP10-4P is appropriate for applications where manufacturer continuity and product status (active) are prioritized.

Both substitutes are functionally equivalent to the discontinued DT04-4P across all critical electrical and mechanical parameters. Selection between AT04-4P and DTP10-4P depends on supply chain requirements, color specification constraints, and manufacturer preference.

Frequently Asked Questions (FAQ)

Q: Can the AT04-4P directly replace the DT04-4P in existing assemblies?

A: The AT04-4P satisfies all functional parameters of the DT04-4P, including connector type, position count, mounting configuration, and operating temperature range. Direct substitution is supported from a functional standpoint. Physical verification of mating interface compatibility with existing harnesses is required.

Q: What is the difference between the DTP10-4P and DT04-4P?

A: Both parts are manufactured by TE Connectivity Deutsch Connectors and share identical functional specifications. The DTP10-4P is an active product, while the DT04-4P is discontinued. The DTP10-4P housing is black rather than gray, and the insulation material is specified as PA46 rather than PA. All electrical and mechanical parameters remain equivalent.

Q: Are there packaging differences between these substitutes?

A: The DT04-4P is packaged in bulk. The AT04-4P is packaged in bulk. The DTP10-4P is packaged in bulk. Packaging format is consistent across all three parts.

Q: Do these parts include contacts?

A: All three parts (DT04-4P, AT04-4P, and DTP10-4P) are connector housings only. Contacts are not included and must be sourced separately.

Q: What compliance certifications apply to these substitutes?

A: All three parts are ROHS3 compliant and REACH unaffected. The DT04-4P and AT04-4P carry MSL 1 (Unlimited) ratings. The DTP10-4P MSL status is not applicable.

Q: Can color differences affect substitution decisions?

A: The DT04-4P and AT04-4P are gray. The DTP10-4P is black. Color selection depends on application requirements and visual identification needs. Functional performance is not affected by housing color.
