ACT90MG35PN Equivalent & Substitute Parts

Part Overview

The ACT90MG35PN is a 79-position circular connector receptacle with male pins, manufactured by TE Connectivity Deutsch Connectors. This MIL-DTL-38999 Series III connector features crimp termination, panel mount flange configuration, and gold-plated mating contacts rated for 5A continuous current. The connector is designed for aerospace and military applications requiring shielded, environment-resistant interconnection in temperature ranges from -65°C to 200°C.

The ACT90MG35PN is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from active manufacturers including Amphenol Aerospace Operations and Conesys, providing functional alternatives that maintain MIL-DTL-38999 Series III compliance and core electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MG35PN are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector type: Receptacle with male pins
• Position count: 79 positions
• Shell size: 21-35 insert designation
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening: Threaded coupling
• Shielding: Shielded construction
• Contact finish: Gold plating on mating surfaces
• Series compliance: MIL-DTL-38999 Series III

Secondary Compatibility Considerations:

• Operating temperature range (minimum -65°C, maximum 175°C to 200°C)
• Contact material: Copper alloy
• Ingress protection: Environment resistant
• RoHS compliance status

Substitutes are grouped into two categories based on shell material composition and orientation specifications. All listed substitutes maintain the core 79-position, 21-35 shell size, crimp termination, and MIL-DTL-38999 Series III compliance required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Identical Orientation (Normal):

The D38999/20FG35PN from Conesys provides the closest functional equivalent to the ACT90MG35PN. Both connectors share identical orientation (N - Normal), shell size MIL designation (G), operating temperature range (-65°C to 200°C), contact finish thickness (50.0µin), and all core mechanical specifications. The D38999/20FG35PN is currently active in production and carries ROHS3 compliance certification, offering improved environmental compliance over the discontinued ACT90MG35PN. The primary difference is shell material composition: aluminum with electroless nickel finish versus composite with nickel finish.

The CTVP00RW-21-35HN from Amphenol Aerospace Operations also provides functional equivalence with identical normal orientation. This connector maintains all critical mechanical parameters and operates across the same temperature range as the ACT90MG35PN. The CTVP00RW-21-35HN features composite shell construction with olive drab cadmium finish and thicker gold plating (100.0µin versus 50.0µin), providing enhanced corrosion resistance. This part is currently active in production.

For Applications Requiring Alternate Orientation:

The CTVP00RW-21-35HA from Amphenol Aerospace Operations is functionally equivalent with the exception of connector orientation (A versus N). This part is suitable for applications where the alternate orientation is mechanically compatible with the installation envelope. Operating temperature range is -65°C to 175°C, which is 25°C lower than the ACT90MG35PN maximum specification.

For Limited Technical Data Applications:

The CTVP00RW-21-35P from Amphenol Aerospace Operations is listed as an active substitute with incomplete technical documentation in available sources. This part is suitable for applications where full parameter verification through manufacturer documentation is feasible.

Compliance Considerations:

Applications requiring RoHS3 compliance should specify the D38999/20FG35PN. Applications without RoHS compliance requirements may select from all listed substitutes based on mechanical and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can the D38999/20FG35PN directly replace the ACT90MG35PN in existing installations?

A: The D38999/20FG35PN is mechanically and electrically compatible for direct replacement. Both connectors share identical 79-position, 21-35 shell size, normal orientation, crimp termination, and threaded fastening specifications. The primary difference is shell material: the D38999/20FG35PN uses aluminum with electroless nickel finish, while the ACT90MG35PN uses composite with nickel finish. Both operate across -65°C to 200°C. Verify mechanical fit in the specific installation before deployment.

Q: What is the difference between the CTVP00RW-21-35HN and CTVP00RW-21-35HA?

A: Both connectors are functionally identical 79-position, 21-35 shell size, cri
