ACT90MH53SN Equivalent & Substitute Parts

Part Overview

The ACT90MH53SN is a 53-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, designed for aerospace and military applications. This connector features female sockets with crimp termination, panel mount configuration with threaded fastening, and operates across a temperature range of -65°C to 200°C. The part is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain functional and electrical compatibility for ongoing system support and new procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MH53SN is determined by strict equivalence across the following critical parameters:

Primary Compatibility Criteria:

• 53-position configuration
• MIL-DTL-38999 Series III compliance
• Receptacle with female sockets
• Panel mount with flange
• Threaded fastening
• Crimp termination
• Composite shell construction
• Gold-plated mating contacts
• Shielded design
• Copper alloy contact material
• Thermoplastic insert material
• Environment resistant ingress protection

Allowable Variations:

• Shell finish (Nickel, Olive Drab Cadmium, Electroless Nickel)
• Housing color (Silver, Olive Drab)
• Contact finish thickness (50.0µin to 100.0µin)
• Operating temperature upper limit (175°C to 200°C)
• RoHS compliance status
• Manufacturer (TE Connectivity Deutsch Connectors, Amphenol Aerospace Operations)

Non-Substitutable Variants:

• Receptacle housing without integrated contacts (CTVP00RW-23-53JN-LC and CTVPS00RF-23-53JN-LC) are housing-only components and do not constitute complete connector substitutes

Engineering Selection Recommendations

Primary Substitute: CTVPS00RF-23-53JN

The CTVPS00RF-23-53JN is the preferred substitute for the ACT90MH53SN. This Amphenol Aerospace Operations connector maintains full functional equivalence across all critical parameters, including 53-position configuration, MIL-DTL-38999 Series III compliance, panel mount flange design, and threaded fastening. The operating temperature range extends to 200°C, matching the original specification. The CTVPS00RF-23-53JN is currently active in production with 985 units in stock. This part achieves ROHS3 compliance, providing regulatory advantage for new designs and procurement cycles.

Secondary Substitute: CTVP00RW-23-53JN

The CTVP00RW-23-53JN provides functional equivalence with one operational constraint. This Amphenol Aerospace connector maintains all critical mechanical and electrical parameters but operates to a maximum temperature of 175°C, compared to the 200°C specification of the original part. This connector is suitable for applications where the upper temperature limit does not exceed 175°C. The part is active in production with 1059 units in stock. Shell finish is Olive Drab Cadmium with RoHS non-compliant status.

Housing-Only Components:

The CTVP00RW-23-53JN-LC and CTVPS00RF-23-53JN-LC are receptacle housings without integrated contacts. These components are not direct substitutes for the complete ACT90MH53SN connector and are applicable only when housing replacement is required as a separate procurement action.

Frequently Asked Questions (FAQ)

Q: Can CTVPS00RF-23-53JN directly replace ACT90MH53SN in existing assemblies?

A: Yes. The CTVPS00RF-23-53JN maintains full mechanical and electrical compatibility with the ACT90MH53SN. Both connectors conform to MIL-DTL-38999 Series III, feature identical 53-position configuration, panel mount flange design, threaded fastening, and crimp termination. The mating interface, pin arrangement, and shell dimensions are equivalent.

Q: What is the difference between CTVPS00RF-23-53JN and CTVP00RW-23-53JN?

A: Both connectors are functionally equivalent with two distinctions. The CTVPS00RF-23-53JN operates to 200°C and achieves ROHS3 compliance, while the CTVP00RW-23-53JN operates to 175°C and is RoHS non-compliant. The CTVPS00RF-23-53JN features electroless nickel shell finish with silver housing color, while the CTVP00RW-23-53JN features olive drab cadmium finish with olive drab housing color.

Q: Why are CTVP00RW-23-53JN-LC and CTVPS00RF-23-53JN-LC not suitable substitutes?

A: These components are receptacle housings only and do not include integrated female socket contacts. They are designed for applications requiring housing replacement as a separate assembly step. The ACT90MH53SN is a complete connector assembly with integrated contacts and cannot be substituted by housing-only components.

Q: What is the significance of the contact finish thickness difference?

A: The ACT90MH53SN specifies 50.0µin (1.27µm) gold plating thickness, while CTVPS00RF-23-53JN and CTVP00RW-23-53JN specify 100.0µin (2.54µm). Both thicknesses meet MIL-DTL-38999 Series III requirements. The increased thickness in substitute parts provides enhanced wear resistance and extended contact life under repeated mating cycles.

Q: Is ROHS3 compliance required for my application?

A: ROHS3 compliance is determined by application requirements and regulatory jurisdiction. The CTVPS00RF-23-53JN achieves ROHS3 compliance, while the ACT90MH53SN and CTVP00RW-23-53JN are RoHS non-compliant. For new designs subject to ROHS3 regulations, the CTVPS00RF-23-53JN is the appropriate selection.

Q: Can I use CTVP00RW-23-53JN in applications requiring 200°C operation?

A: No. The CTVP00RW-23-53JN is rated to 175°C maximum operating temperature. Applications requiring sustained operation at temperatures between 175°C and 200°C must use the CTVPS00RF-23-53JN, which is rated to 200°C.

Q: Are the shell finishes (Nickel, Olive Drab Cadmium, Electroless Nickel) electrically equivalent?

A: Yes. All shell finishes provide equivalent electrical shielding and environmental protection. Shell finish selection is determined by application environment, corrosion resistance requirements, and aesthetic specifications rather than electrical performance.

Q: What is the current rating for these connectors?

A: The ACT90MH53SN specifies 7.5A current rating. The CTVPS00RF-23-53JN and CTVP00RW-23-53JN do not specify current rating in the provided technical data. Current capacity is determined by individual contact specifications and wire gauge, which are not included in this comparison.
