Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Full Compatibility:

The CTVPS00RF-19-35SA-LC (Amphenol Aerospace Operations) is the recommended substitute for the DTS20F19-35SA. This part maintains complete electrical and mechanical compatibility with all critical parameters: 66 positions, 19-35 shell size, panel mount flange configuration, crimp termination, threaded fastening, and full -65°C to 200°C operating temperature range. The part is ROHS3 compliant and carries active product status with 816 units in stock. The composite shell construction with electroless nickel finish provides equivalent environmental sealing performance.

Alternative Substitute - Full Compatibility:

The CTVPS00RF-19-35JA (Amphenol Aerospace Operations) provides complete functional equivalence with the added benefit of increased contact finish thickness (100.0µin versus 50.0µin), enhancing contact durability. This part is ROHS3 compliant, active, and available with 953 units in stock. The -65°C to 200°C operating temperature range matches the original specification exactly.

Secondary Substitute - Temperature Consideration:

The CTVP00RW-19-35SA-LC (Amphenol Aerospace Operations) is functionally equivalent with one exception: the maximum operating temperature is limited to -65°C to 175°C, which is 25°C below the DTS20F19-35SA specification. This part is suitable only for applications where the upper temperature limit does not exceed 175°C. The part is RoHS non-compliant and available with 940 units in stock.

Alternative Substitute - Direct Equivalent:

The D38999/20FF35SA (Souriau-Sunbank by Eaton) provides direct electrical and mechanical equivalence with aluminum alloy shell construction and nickel finish matching the original design. This part is ROHS3 compliant, active, and available with 689 units in stock. The IP67 ingress protection rating and self-locking feature provide enhanced environmental performance.

Connector Housing-Only Substitutes:

The CTVP00RW-19-35SA-LC and CTVPS00RF-19-35JA-LC are receptacle housings without integrated contacts. These parts are suitable only for applications where contacts are sourced separately and installed into the housing. Both parts maintain the 66-position, 19-35 shell size, panel mount flange configuration, and threaded fastening of the original part.

Frequently Asked Questions (FAQ)

Q: Can the CTVPS00RF-19-35SA-LC be used as a direct replacement for the DTS20F19-35SA?

A: Yes. The CTVPS00RF-19-35SA-LC maintains all critical electrical and mechanical parameters: 66 positions, 19-35 shell size, panel mount flange, crimp termination, threaded fastening, and -65°C to 200°C operating temperature range. Both parts are MIL-DTL-38999 Series III qualified and ROHS3 compliant.

Q: What is the difference between CTVPS00RF-19-35SA-LC and CTVPS00RF-19-35JA-LC?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is the housing color designation (SA versus JA suffix). Both maintain full compatibility with the DTS20F19-35SA and operate across -65°C to 200°C.

Q: Why does the CTVP00RW-19-35SA-LC have a lower maximum operating temperature?

A: The CTVP00RW-19-35SA-LC is specified for -65°C to 175°C operation, which is 25°C below the DTS20F19-35SA maximum of 200°C. This part is suitable only for applications where the upper temperature limit does not exceed 175°C.

Q: What does the "-LC" suffix indicate on Amphenol parts?

A: The "-LC" suffix indicates a receptacle housing configuration without integrated contacts. Contacts must be sourced and installed separately. Parts without this suffix include integrated female sockets.

Q: Are all substitute parts ROHS3 compliant?

A: No. The CTVP00RW-19-35SA-LC is RoHS non-compliant. All other substitutes listed (CTVPS00RF-19-35JA, CTVPS00RF-19-35JA-LC, CTVPS00RF-19-35SA-LC, and D38999/20FF35SA) are ROHS3 compliant.

Q: What is the difference between aluminum and composite shell materials?

A: The DTS20F19-35SA uses aluminum shell construction, while most Amphenol substitutes use composite materials. Both materials provide equivalent environmental sealing and mechanical performance for MIL-DTL-38999 Series III applications. The D38999/20FF35SA uses aluminum alloy construction, matching the original material.

Q: Can I use a connector housing part (with "-LC" suffix) as a direct replacement?

A: No. Connector housing parts (CTVP00RW-19-35SA-LC, CTVPS00RF-19-35JA-LC, CTVPS00RF-19-35SA-LC) do not include integrated contacts. These parts require separate contact procurement and installation. Use only parts without the "-LC" suffix for direct replacement applications.

Q: What is the contact finish thickness difference between substitutes?

A: The DTS20F19-35SA and D38999/20FF35SA specify 50.0µin (1.27µm) gold plating. The CTVPS00RF-19-35JA specifies 100.0µin (2.54µm), providing double the plating thickness for enhanced contact durability and wear resistance.

Q: Are all substitutes qualified to MIL-DTL-38999 Series III?

A: Yes. All substitute parts listed are qualified to MIL-DTL-38999 Series III specifications, ensuring electrical and mechanical compatibility with the DTS20F19-35SA.
