Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MD35PN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with male pins
• Position count: 37 positions
• Shell size insert: 15-35
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Orientation: Normal (N)
• Shell material: Composite
• Contact finish: Gold plating
• Shielding: Shielded design
• Operating temperature range: -65°C to 200°C
• Contact material: Copper alloy
• Insert material: Thermoplastic
• Series standard: MIL-DTL-38999 Series III compliance

The CTVPS00RF-15-35HN from Amphenol Aerospace Operations satisfies all mandatory matching parameters and qualifies as a direct substitute for the ACT90MD35PN.

Parameter Comparison

Engineering Selection Recommendations

The CTVPS00RF-15-35HN from Amphenol Aerospace Operations is a direct functional equivalent to the discontinued ACT90MD35PN. Selection of this substitute is supported by the following factors:

Functional Equivalence: All critical electrical and mechanical parameters match the original specification. Both connectors comply with MIL-DTL-38999 Series III standards and are rated for identical operating temperature ranges (-65°C to 200°C).

Enhanced Contact Plating: The CTVPS00RF-15-35HN provides 100.0µin (2.54µm) gold plating thickness on mating contacts, exceeding the original 50.0µin (1.27µm) specification. This enhancement provides improved durability and contact reliability.

Improved Compliance Status: The substitute part is ROHS3 compliant, whereas the original ACT90MD35PN is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for aerospace and military applications.

Active Product Status: The CTVPS00RF-15-35HN maintains active production status with confirmed inventory availability (1115 pieces in stock), ensuring supply chain continuity and long-term availability.

Identical Application Scope: Both connectors are qualified for aerospace, military, and related high-reliability applications requiring shielded, crimp-terminated circular connectors.

Frequently Asked Questions (FAQ)

Q: Can the CTVPS00RF-15-35HN be used as a direct replacement for the ACT90MD35PN in existing assemblies?

A: Yes. The CTVPS00RF-15-35HN is a direct functional equivalent. Both connectors share identical position counts (37), shell sizes (15-35), mounting configurations (panel mount with flange), termination methods (crimp), and operating temperature ranges (-65°C to 200°C). Mating interfaces and mechanical dimensions are equivalent.

Q: What is the difference between the nickel and electroless nickel shell finishes?

A: Both finishes provide equivalent corrosion resistance and environmental protection for composite shells. Electroless nickel (used in the CTVPS00RF-15-35HN) is applied through a chemical deposition process, while standard nickel (used in the ACT90MD35PN) is typically electroplated. Both finishes meet MIL-DTL-38999 Series III requirements.

Q: Why does the CTVPS00RF-15-35HN have thicker gold plating on the contacts?

A: The 100.0µin (2.54µm) gold plating thickness on the Amphenol connector exceeds the original 50.0µin (1.27µm) specification. This enhancement provides extended contact life, improved wear resistance, and superior performance in high-cycle mating applications.

Q: Is the CTVPS00RF-15-35HN suitable for aerospace and military applications?

A: Yes. The CTVPS00RF-15-35HN is qualified for aerospace, aviation, marine, and military applications. It complies with MIL-DTL-38999 Series III standards and maintains ROHS3 compliance, meeting current regulatory requirements for these sectors.

Q: What is the current availability of the CTVPS00RF-15-35HN?

A: The CTVPS00RF-15-35HN is an active product with 1115 pieces in stock as new original inventory. The ACT90MD35PN is discontinued at DiGi Electronics, making the Amphenol substitute the recommended selection for new procurements.

Q: Are the crimp termination specifications identical between both connectors?

A: Both connectors use crimp termination with copper alloy contacts and thermoplastic inserts. Crimp tool specifications and contact sizing are equivalent, allowing use of existing crimping equipment and procedures.

Q: Does the CTVPS00RF-15-35HN maintain the same shielding effectiveness as the ACT90MD35PN?

A: Yes. Both connectors feature shielded designs with composite shells and equivalent environmental resistance ratings. Shielding performance and electromagnetic interference protection are functionally equivalent.
