Engineering Selection Recommendations

CTVPS00RF-15-35JN (Amphenol Aerospace Operations)

This substitute part is the primary selection for new designs and replacement applications. It maintains full electrical and mechanical compatibility with the ACT90MD35SN across all critical parameters. The CTVPS00RF-15-35JN offers the following advantages:

• Active product status with confirmed inventory availability (661 pcs)
• Operating temperature range of -65°C to 200°C, matching the original specification
• RoHS3 compliance, meeting current environmental and regulatory requirements
• Electroless nickel shell finish with 100.0µin gold contact plating, providing enhanced corrosion resistance
• MIL-DTL-38999 Series III qualification maintained

CTVP00RW-15-35JN (Amphenol Aerospace Operations)

This substitute part provides an alternative with active product status and higher inventory availability (1056 pcs). Selection of this part requires consideration of the following:

• Operating temperature upper limit of 175°C, which is 25°C below the original specification
• Olive Drab Cadmium shell finish, suitable for military applications with specific environmental requirements
• RoHS non-compliant status, consistent with the original part
• 100.0µin gold contact plating thickness, exceeding the original specification

The CTVP00RW-15-35JN is suitable for applications where the 175°C upper temperature limit is acceptable and where Olive Drab Cadmium finish is specified or preferred.

Frequently Asked Questions (FAQ)

Q: Can the CTVPS00RF-15-35JN be used as a direct replacement for the ACT90MD35SN?

A: Yes. The CTVPS00RF-15-35JN meets all mandatory electrical and mechanical parameters. Both connectors are 37-position receptacles with crimp termination, composite shells, gold-plated contacts, and MIL-DTL-38999 Series III qualification. The primary differences are shell finish material and RoHS compliance status.

Q: What is the significance of the operating temperature difference between the ACT90MD35SN and CTVP00RW-15-35JN?

A: The ACT90MD35SN operates to 200°C, while the CTVP00RW-15-35JN operates to 175°C. Applications requiring sustained operation above 175°C must use the CTVPS00RF-15-35JN, which maintains the 200°C upper limit. Applications with maximum operating temperatures at or below 175°C can use either substitute.

Q: Are there compatibility concerns with mating connectors?

A: No. All three connectors share identical shell size (15-35), position count (37), mounting configuration (panel mount flange), and fastening type (threaded). Mating plugs designed for the ACT90MD35SN are compatible with both substitute receptacles.

Q: What does RoHS3 compliance mean for the CTVPS00RF-15-35JN?

A: RoHS3 compliance indicates the connector meets current European Union Restriction of Hazardous Substances regulations. This is relevant for applications subject to environmental compliance requirements or procurement specifications mandating RoHS compliance. The original ACT90MD35SN and CTVP00RW-15-35JN are RoHS non-compliant.

Q: How do the contact finish thicknesses compare?

A: The ACT90MD35SN has 50.0µin (1.27µm) gold plating on mating contacts. Both Amphenol substitutes provide 100.0µin (2.54µm) gold plating, which exceeds the original specification and provides enhanced durability and corrosion resistance.

Q: What is the difference between Nickel, Olive Drab Cadmium, and Electroless Nickel shell finishes?

A: Shell finish affects corrosion resistance and environmental suitability. Nickel provides standard corrosion protection. Olive Drab Cadmium is specified for military applications with specific environmental requirements. Electroless Nickel provides enhanced corrosion resistance and is compatible with RoHS compliance. Selection depends on application environment and procurement specifications.

Q: Are both Amphenol substitutes available in the same quantities?

A: No. The CTVP00RW-15-35JN has 1056 pcs in stock, while the CTVPS00RF-15-35JN has 661 pcs in stock. Availability should be confirmed at the time of procurement.

Q: Can the shell finish be changed after manufacturing?

A: No. Shell finish is applied during manufacturing and cannot be altered. Selection of the appropriate finish must occur at the procurement stage based on application requirements.
