Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90WG41PN is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 41
• Shell size insert designation: 21-41
• Series compliance: MIL-DTL-38999 Series III
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding: Shielded construction
• Operating temperature range: -65°C to 175°C
• Contact finish: Gold plating on mating surfaces
• Shell material: Composite construction
• Shell finish: Olive drab cadmium

The CTVP00RW-21-41HN from Amphenol Aerospace Operations satisfies all mandatory parameters and qualifies as a direct substitute. Both connectors conform to MIL-DTL-38999 Series III specifications and maintain identical mechanical and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The CTVP00RW-21-41HN serves as a direct functional equivalent to the ACT90WG41PN. Both connectors comply with MIL-DTL-38999 Series III specifications and maintain identical mechanical interfaces, electrical characteristics, and environmental ratings required for aerospace and military applications.

Product Status Consideration: The ACT90WG41PN is discontinued at DiGi Electronics, while the CTVP00RW-21-41HN maintains active product status with higher current inventory availability (915 units versus 692 units). This status differential supports selection of the Amphenol alternative for new procurement activities.

Compliance Alignment: Both parts carry identical RoHS non-compliant status, ECCN classification (EAR99), and HTSUS codes (8536.69.4020), ensuring regulatory consistency in system integration.

Contact Finish Specification: The CTVP00RW-21-41HN features 100.0µin (2.54µm) contact finish thickness compared to 50.0µin (1.27µm) on the ACT90WG41PN. This increased thickness on the substitute part provides enhanced durability and mating cycle performance while maintaining gold plating specification.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-41HN directly replace the ACT90WG41PN in existing assemblies?

A: Yes. Both connectors conform to MIL-DTL-38999 Series III specifications with identical 41-position, size 21-41 configurations. Mechanical and electrical interfaces are fully compatible. Pin assignments and mating cycles are equivalent.

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

A: The CTVP00RW-21-41HN provides 100.0µin (2.54µm) gold plating versus 50.0µin (1.27µm) on the ACT90WG41PN. Both thicknesses satisfy MIL-DTL-38999 Series III requirements. The increased thickness on the substitute part extends contact life and improves resistance to wear during mating operations.

Q: Are there differences in current rating specifications?

A: The ACT90WG41PN specifies 7.5A current rating. The CTVP00RW-21-41HN does not provide a current rating specification in available documentation. For applications requiring explicit current rating verification, consult manufacturer datasheets or contact the supplier directly.

Q: Do both connectors support identical operating temperature ranges?

A: Yes. Both the ACT90WG41PN and CTVP00RW-21-41HN operate across -65°C to 175°C, meeting aerospace and military environmental specifications.

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

A: Both connectors comply with MIL-DTL-38999 Series III. The ACT designation identifies the TE Connectivity product line, while Tri-Start™ TV identifies the Amphenol Aerospace Operations product line. Series III compliance ensures mechanical and electrical interchangeability.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both connectors carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: What applications are supported by the CTVP00RW-21-41HN?

A: The substitute part supports aviation, marine, and military applications. The original ACT90WG41PN is specified for aerospace and military use. The expanded application range of the substitute part maintains compatibility with original system requirements.
