Engineering Selection Recommendations

CTVP00RW-15-35JN (Amphenol Aerospace Operations)

This substitute maintains full electrical and mechanical compatibility with the ACT90WD35SN. Both connectors share identical shell size, position count, mounting configuration, and termination method. The CTVP00RW-15-35JN features increased contact finish thickness (100.0µin versus 50.0µin), providing enhanced durability. The part is currently active in production, ensuring availability. Shell finish remains Olive Drab Cadmium, matching the original specification. RoHS non-compliance status is consistent with the main part. This option is suitable for direct replacement in existing aerospace and military applications without design modification.

CTVPS00RF-15-35JN (Amphenol Aerospace Operations)

This substitute provides full compatibility across all critical mechanical and electrical parameters. The CTVPS00RF-15-35JN extends the operating temperature range to -65°C ~ 200°C, exceeding the original -65°C ~ 175°C specification. The shell finish differs, utilizing Electroless Nickel instead of Olive Drab Cadmium, and the connector color is Silver rather than Olive Drab. Contact finish thickness is increased to 100.0µin. Notably, this part achieves ROHS3 compliance, addressing environmental regulatory requirements where applicable. The extended temperature range and improved compliance status make this option suitable for applications requiring enhanced environmental performance or regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-15-35JN be used as a direct replacement for the ACT90WD35SN?

A: Yes. Both connectors are 37-position receptacles with identical shell size (15-35), panel mount flange configuration, crimp termination, and threaded fastening. They conform to MIL-DTL-38999 Series III and operate across the same temperature range (-65°C ~ 175°C). The CTVP00RW-15-35JN is currently in active production, addressing the discontinuation of the ACT90WD35SN.

Q: What is the difference between the two Amphenol substitutes?

A: The primary differences are shell finish and operating temperature range. The CTVP00RW-15-35JN maintains Olive Drab Cadmium finish matching the original part. The CTVPS00RF-15-35JN uses Electroless Nickel finish and extends the maximum operating temperature to 200°C. Additionally, the CTVPS00RF-15-35JN is ROHS3 compliant, while the CTVP00RW-15-35JN is RoHS non-compliant.

Q: Are there any compatibility concerns with contact finish thickness differences?

A: No. The substitute parts feature increased contact finish thickness (100.0µin versus 50.0µin on the original). This enhancement provides greater durability and wear resistance without affecting electrical or mechanical compatibility. Both thicknesses satisfy MIL-DTL-38999 Series III requirements.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For direct replacement in existing systems, either substitute is acceptable. For applications requiring enhanced environmental compliance, the CTVPS00RF-15-35JN offers ROHS3 certification. For applications operating above 175°C, the CTVPS00RF-15-35JN supports temperatures to 200°C.

Q: Do the substitute parts maintain the same crimp contact specifications?

A: Yes. Both substitute connectors utilize crimp termination with copper alloy contacts and gold plating on mating surfaces. The increased contact finish thickness on the substitutes provides additional protection without altering the crimp interface or contact geometry.

Q: Are there any shell material or insert material differences?

A: No. All three connectors feature composite shell material and thermoplastic insert material. The substitutes maintain identical material composition and environmental resistance ratings.

Q: What is the significance of the different shell finishes?

A: Shell finish affects corrosion resistance and appearance. Olive Drab Cadmium (original and CTVP00RW-15-35JN) provides traditional military specification finish. Electroless Nickel (CTVPS00RF-15-35JN) offers improved corrosion resistance and is compatible with RoHS3 compliance requirements. Both finishes are environment resistant and suitable for aerospace and military applications.
