Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MG41PN are identified based on strict electrical and mechanical parameter alignment within the MIL-DTL-38999 Series III circular connector category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector type: Receptacle with male pins
• Position count: 41 positions
• Shell size insert designation: 21-41
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding: Shielded construction
• Contact finish: Gold plating on mating surfaces
• Series compliance: MIL-DTL-38999 Series III

Allowable Variation Parameters:

• Shell finish (Nickel vs. Olive Drab Cadmium)
• Operating temperature upper limit (200°C vs. 175°C)
• Contact finish thickness (50.0µin vs. 100.0µin)
• Current rating specification availability

Parts meeting all critical matching parameters qualify as functional equivalents despite variations in finish specifications and temperature ratings.

Engineering Selection Recommendations

ACT90MG41PN (TE Connectivity Deutsch Connectors)

This part is discontinued at DiGi Electronics. Current inventory of 842 pieces is available through existing stock channels. The part carries RoHS non-compliant status and operates to 200°C with 7.5A current rating. Selection of this part is limited to applications where existing inventory is accessible and discontinuation does not impact supply chain requirements.

CTVP00RW-21-41HN (Amphenol Aerospace Operations)

This part maintains active product status with 915 pieces in current inventory. It is functionally equivalent to the ACT90MG41PN across all critical mechanical and electrical parameters. The CTVP00RW-21-41HN operates to 175°C maximum temperature and features thicker gold plating (100.0µin vs. 50.0µin). Both parts comply with MIL-DTL-38999 Series III, carry EAR99 export classification, and share identical HTSUS coding. The Amphenol part is suitable for applications where the 175°C upper temperature limit is acceptable and where active product availability is required for ongoing production or maintenance programs.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-41HN directly replace the ACT90MG41PN in existing assemblies?

A: The CTVP00RW-21-41HN is mechanically and electrically compatible with the ACT90MG41PN. Both connectors share identical position count (41), shell size (21-41), mounting configuration (panel mount flange), termination method (crimp), and fastening type (threaded). Compatibility is established for applications operating within the CTVP00RW-21-41HN temperature range of -65°C to 175°C.

Q: What is the significance of the shell finish difference between these parts?

A: The ACT90MG41PN features nickel shell finish, while the CTVP00RW-21-41HN features olive drab cadmium finish. Both finishes provide corrosion resistance and environmental protection. Shell finish selection is typically driven by application-specific requirements, system color coding standards, or environmental specifications. The finish difference does not affect electrical performance or mechanical compatibility.

Q: How does the contact finish thickness difference impact connector performance?

A: The CTVP00RW-21-41HN provides 100.0µin (2.54µm) gold plating thickness compared to 50.0µin (1.27µm) on the ACT90MG41PN. Thicker gold plating extends contact life and improves resistance to wear during mating cycles. Both thicknesses meet MIL-DTL-38999 Series III requirements. The thicker plating on the Amphenol part provides enhanced durability for high-cycle applications.

Q: Why is the current rating not specified for the CTVP00RW-21-41HN?

A: The current rating specification is not provided in the available technical data for the CTVP00RW-21-41HN. Both connectors are MIL-DTL-38999 Series III compliant 41-position receptacles with identical contact materials (copper alloy) and configurations. For applications requiring specific current rating verification, manufacturer technical documentation should be consulted.

Q: Are both parts suitable for aerospace and military applications?

A: The ACT90MG41PN is specified for aerospace and military applications. The CTVP00RW-21-41HN is specified for aviation, marine, and military applications. Both parts comply with MIL-DTL-38999 Series III and carry EAR99 export classification. Both are RoHS non-compliant and share identical HTSUS coding (8536.69.4020), indicating equivalent regulatory and compliance status for aerospace and defense procurement.

Q: What is the operational temperature consideration when substituting these parts?

A: The ACT90MG41PN operates from -65°C to 200°C, while the CTVP00RW-21-41HN operates from -65°C to 175°C. The 25°C difference in upper temperature limit must be evaluated against specific application requirements. For applications operating above 175°C, the ACT90MG41PN is required. For applications operating at or below 175°C, both parts are suitable.

Q: Do both connectors have identical moisture sensitivity levels?

A: Both the ACT90MG41PN and CTVP00RW-21-41HN carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). This indicates no moisture sensitivity restrictions for storage, handling, or use. Both parts are suitable for standard industrial storage and handling conditions without special moisture control requirements.
