DTS20F25-19SA Equivalent & Substitute Parts

Part Overview

The DTS20F25-19SA is a 19-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, conforming to MIL-DTL-38999 Series III specifications. This female socket connector features crimp termination, panel mount configuration with threaded fastening, and gold-plated mating contacts rated for 23A continuous current. The connector is designed for aerospace, marine, and military applications requiring sealed environmental protection across an operating temperature range of -65°C to 200°C.

The DTS20F25-19SA is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing harness designs and system requirements. Substitute connectors must preserve the 19-position configuration, shell size 25-19, crimp termination method, panel mount flange, and threaded fastening to ensure direct replacement capability.

Engineering Selection Recommendations

CTVP00RW-25-19SA (Amphenol Aerospace Operations)

This substitute maintains full mechanical and electrical compatibility with the DTS20F25-19SA across all primary substitution criteria. The connector is currently in active production status, ensuring long-term availability and supply chain stability. Both connectors conform to MIL-DTL-38999 Series III specifications with identical shell size 25-19, 19-position configuration, crimp termination, and gold-plated copper alloy contacts.

The CTVP00RW-25-19SA operates across -65°C to 175°C, which covers the lower end of the DTS20F25-19SA temperature range (-65°C to 200°C). Applications requiring operation above 175°C require evaluation against specific system thermal requirements. The substitute features shielded construction and environment-resistant ingress protection, providing enhanced electromagnetic compatibility compared to the original part.

RoHS compliance differs between the two connectors: the DTS20F25-19SA is ROHS3 compliant, while the CTVP00RW-25-19SA is RoHS non-compliant. Systems subject to RoHS regulatory requirements must account for this distinction in component selection.

CTVPS00RF-25-19SA-LC (Amphenol Aerospace Operations)

This substitute is a receptacle housing assembly designed for female socket contacts, requiring separate contact procurement and assembly. The housing maintains full mechanical compatibility with the DTS20F25-19SA, including identical shell size 25-19, 19-position configuration, panel mount flange, and threaded fastening. The connector operates across -65°C to 200°C, matching the full temperature range of the original part.

The CTVPS00RF-25-19SA-LC is currently in active production and ROHS3 compliant, aligning with regulatory requirements of the discontinued DTS20F25-19SA. The housing features shielded construction and environment-resistant ingress protection. This option is suitable for applications where contact replacement or custom contact configurations are required, but necessitates additional procurement and assembly steps compared to fully assembled alternatives.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-25-19SA directly replace the DTS20F25-19SA in existing harnesses?

A: The CTVP00RW-25-19SA maintains mechanical and electrical compatibility across all primary substitution criteria, including shell size 25-19, 19-position configuration, crimp termination, panel mount flange, and threaded fastening. Direct replacement is supported for applications operating within the -65°C to 175°C temperature range. Applications requiring operation above 175°C require thermal evaluation against system specifications.

Q: What is the difference between the CTVP00RW-25-19SA and CTVPS00RF-25-19SA-LC?

A: The CTVP00RW-25-19SA is a fully assembled receptacle connector with integrated female socket contacts ready for installation. The CTVPS00RF-25-19SA-LC is a receptacle housing assembly without contacts included, requiring separate contact procurement and manual assembly. Both maintain identical mechanical compatibility with the DTS20F25-19SA. The housing-only option is selected when custom contact configurations or replacement of damaged contacts is required.

Q: Are there RoHS compliance differences between substitute options?

A: The CTVP00RW-25-19SA is RoHS non-compliant, while the CTVPS00RF-25-19SA-LC is ROHS3 compliant. The original DTS20F25-19SA is ROHS3 compliant. Systems subject to RoHS regulatory requirements must select the CTVPS00RF-25-19SA-LC or identify alternative compliant sources.

Q: What is the operating temperature limitation of the CTVP00RW-25-19SA?

A: The CTVP00RW-25-19SA operates across -65°C to 175°C, compared to the DTS20F25-19SA range of -65°C to 200°C. The 25°C upper temperature difference must be evaluated against specific application thermal requirements. Applications with sustained operation above 175°C require alternative component selection or thermal management review.

Q: Do the substitute connectors maintain the same current rating as the DTS20F25-19SA?

A: The DTS20F25-19SA specifies a 23A current rating. The CTVP00RW-25-19SA and CTVPS00RF-25-19SA-LC do not provide explicit current rating specifications in available documentation. Current capacity must be confirmed through manufacturer technical specifications or application engineering review prior to deployment in high-current circuits.

Q: What is the difference between "Environment Sealed" and "Environment Resistant" ingress protection?

A: The DTS20F25-19SA specifies "Environment Sealed" ingress protection, while both substitute connectors specify "Environment Resistant." Both classifications provide protection against environmental contamination in aerospace, marine, and military applications. The specific performance differences between these classifications are determined by MIL-DTL-38999 Series III specifications and must be confirmed through detailed environmental testing requirements for the application.

Q: Are the substitute connectors available in the same quantities as the discontinued DTS20F25-19SA?

A: Current inventory for the CTVP00RW-25-19SA is 975 pieces and for the CTVPS00RF-25-19SA-LC is 1061 pieces, compared to 1067 pieces available for the discontinued DTS20F25-19SA. Both substitute options maintain adequate stock levels for immediate procurement.
