Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MG41SN is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 41 positions
• 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 requirement: Shielded
• Contact finish: Gold plating on mating surfaces
• Orientation: Normal (N)

Allowable Variations:

• Shell finish color (Nickel to Olive Drab Cadmium)
• Contact finish thickness (50.0µin to 100.0µin)
• Operating temperature upper limit (200°C to 175°C)
• Manufacturer and base product number
• Current rating specification presence

The CTVP00RW-21-41JN from Amphenol Aerospace Operations satisfies all critical matching parameters while maintaining MIL-DTL-38999 Series III compliance.

Parameter Comparison

Engineering Selection Recommendations

The CTVP00RW-21-41JN from Amphenol Aerospace Operations is a direct functional equivalent to the discontinued ACT90MG41SN. Both connectors comply with MIL-DTL-38999 Series III specifications and share identical critical parameters: 41-position configuration, shell size 21-41, panel-mount flange design, threaded fastening, crimp termination, and shielded construction with gold-plated contacts.

The primary distinction is product status: the ACT90MG41SN is discontinued, while the CTVP00RW-21-41JN maintains active production status with 1085 units in stock. Both parts carry identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS codes, indicating equivalent regulatory treatment.

The CTVP00RW-21-41JN exhibits a higher contact finish thickness (100.0µin versus 50.0µin), which provides enhanced durability in mating cycles. The operating temperature upper limit of 175°C on the Amphenol part is 25°C lower than the TE Connectivity specification; this difference is application-dependent and must be evaluated against specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-41JN directly replace the ACT90MG41SN in existing assemblies?

A: Yes. Both connectors meet MIL-DTL-38999 Series III specifications with identical position counts (41), shell sizes (21-41), mounting configurations (panel mount with flange), termination methods (crimp), and fastening types (threaded). Mechanical and electrical interfaces are compatible.

Q: What is the significance of the different shell finishes (Nickel versus Olive Drab Cadmium)?

A: Shell finish is a cosmetic and corrosion-resistance property. Nickel provides standard corrosion protection, while Olive Drab Cadmium offers enhanced environmental resistance, particularly in marine and harsh outdoor applications. Both finishes are compliant with MIL-DTL-38999 Series III. Selection depends on environmental exposure requirements.

Q: Does the higher contact finish thickness on the Amphenol part affect performance?

A: Contact finish thickness (100.0µin on CTVP00RW-21-41JN versus 50.0µin on ACT90MG41SN) influences contact durability and mating cycle life. The thicker plating on the Amphenol connector provides extended wear resistance. Both thicknesses meet MIL-DTL-38999 Series III requirements.

Q: Why is the operating temperature range different between the two parts?

A: The ACT90MG41SN supports -65°C to 200°C, while the CTVP00RW-21-41JN supports -65°C to 175°C. This difference reflects design variations between manufacturers. Applications requiring operation above 175°C must use the TE Connectivity part or identify alternative solutions. Most aerospace and military applications operate within the 175°C upper limit.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS non-compliant, carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, and maintain MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory treatment is equivalent.

Q: What is the inventory status for each part?

A: The ACT90MG41SN has 662 units in stock but is discontinued at DiGi Electronics. The CTVP00RW-21-41JN has 1085 units in stock and maintains active production status, ensuring long-term availability.
