ACT90WG41SN Equivalent & Substitute Parts

Part Overview

The ACT90WG41SN is a 41-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors. This female socket connector features crimp termination, panel mount flange configuration, and is designed for aerospace and military applications. The connector is compliant with MIL-DTL-38999 Series III specifications and provides shielded, environment-resistant performance across an operating temperature range of -65°C to 175°C.

The ACT90WG41SN is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new production requirements where this connector specification is mandated.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90WG41SN are identified based on strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Connector type: Receptacle with female sockets
• Position count: 41 positions
• Shell size classification: 21-41 insert size
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Orientation: Normal (N)

Environmental & Material Equivalence Criteria:

• Shell material: Composite construction
• Shell finish: Olive Drab Cadmium
• Contact finish: Gold plating on mating surfaces
• Shielding: Shielded configuration
• Operating temperature range: -65°C to 175°C
• Contact material: Copper alloy
• Insert material: Thermoplastic

Compliance Equivalence Criteria:

• MIL-DTL-38999 Series III compliance
• RoHS non-compliant status
• MSL Level 1 (Unlimited)

The CTVP00RW-21-41JN from Amphenol Aerospace Operations meets all functional, environmental, and compliance equivalence criteria, establishing it as a direct substitute for the discontinued ACT90WG41SN.

Parameter Comparison

Engineering Selection Recommendations

The CTVP00RW-21-41JN is a direct functional equivalent to the ACT90WG41SN. Both connectors comply with MIL-DTL-38999 Series III specifications and share identical electrical, mechanical, and environmental characteristics across all critical parameters.

Product Status Consideration: The ACT90WG41SN is discontinued at DiGi Electronics, whereas the CTVP00RW-21-41JN maintains active product status with current inventory availability. This status differential establishes the Amphenol Aerospace connector as the appropriate selection for ongoing procurement requirements.

Compliance Alignment: Both parts maintain identical RoHS non-compliant status, MSL Level 1 classification, ECCN designation (EAR99), and HTSUS coding (8536.69.4020). No compliance barriers exist for substitution.

Contact Finish Specification: The ACT90WG41SN specifies 50.0µin (1.27µm) gold contact finish thickness, while the CTVP00RW-21-41JN specifies 100.0µin (2.54µm). The Amphenol part provides enhanced gold plating thickness, which extends contact durability and mating cycle performance.

Current Rating Difference: The ACT90WG41SN specifies 7.5A current rating. The CTVP00RW-21-41JN does not provide a current rating specification in available documentation. Applications requiring explicit current rating verification should reference manufacturer datasheets.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-41JN directly replace the ACT90WG41SN in existing assemblies?

A: Yes. Both connectors are 41-position receptacles with identical shell size (21-41), mounting configuration (panel mount flange), termination method (crimp), and fastening type (threaded). They share the same operating temperature range (-65°C to 175°C), shielding, and material specifications. Direct mechanical and electrical compatibility is established.

Q: What is the significance of the different contact finish thicknesses?

A: The ACT90WG41SN specifies 50.0µin (1.27µm) gold plating, while the CTVP00RW-21-41JN specifies 100.0µin (2.54µm). The thicker gold plating on the Amphenol connector provides increased resistance to wear and corrosion during mating cycles, potentially extending connector service life in high-cycle applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both connectors maintain identical RoHS non-compliant status, MSL Level 1 classification, ECCN designation (EAR99), and HTSUS coding (8536.69.4020). They are equivalent from a regulatory and compliance standpoint.

Q: Why is the ACT90WG41SN discontinued?

A: The ACT90WG41SN is discontinued at DiGi Electronics. The CTVP00RW-21-41JN maintains active product status and represents the current market availability for this connector specification.

Q: What applications are these connectors designed for?

A: The ACT90WG41SN is specified for aerospace and military applications. The CTVP00RW-21-41JN is specified for aviation, marine, and military applications. Both are MIL-DTL-38999 Series III compliant and suitable for demanding environmental conditions.

Q: Are there inventory considerations for these parts?

A: Current inventory shows 1090 pieces of the ACT90WG41SN and 1085 pieces of the CTVP00RW-21-41JN available as new original stock. Inventory levels should be verified with suppliers for time-sensitive procurement requirements.

Q: What is the difference between the ACT and Tri-Start™ TV series designations?

A: The ACT90WG41SN belongs to the TE Connectivity Deutsch ACT series, while the CTVP00RW-21-41JN belongs to the Amphenol Aerospace Tri-Start™ TV series. Both series comply with MIL-DTL-38999 Series III specifications. The series designation reflects manufacturer product line classification rather than functional differences.
