Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MG35SN are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 79 positions
• Shell size designation: 21-35
• 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 Variations:

• Shell finish color (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 (5A vs. not specified)
• Manufacturer and base product number

The CTVP00RW-21-35JN from Amphenol Aerospace Operations meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

ACT90MG35SN (TE Connectivity Deutsch Connectors): Product status is discontinued at DiGi Electronics. This part remains suitable for applications where existing inventory is available and replacement stock is not required. Current inventory of 1030 pieces is available through original stock channels.

CTVP00RW-21-35JN (Amphenol Aerospace Operations): Product status is active with 1056 pieces in current inventory. This substitute part is recommended for new procurement and system maintenance where component replacement is necessary. The active product status ensures long-term availability and supply chain continuity. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, confirming regulatory equivalence for export and tariff purposes.

The operating temperature upper limit of the Amphenol part is 175°C compared to 200°C for the TE Connectivity part. Applications requiring sustained operation above 175°C require verification against specific system thermal requirements. The Amphenol part provides thicker gold plating (100.0µin vs. 50.0µin), which may provide enhanced contact durability in high-cycle mating applications.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-35JN directly replace the ACT90MG35SN in existing assemblies?

A: Yes. Both connectors are 79-position receptacles with identical shell size (21-35), mounting configuration (panel mount flange), termination method (crimp), and fastening type (threaded). Mechanical and electrical interfaces are equivalent. The substitute part maintains MIL-DTL-38999 Series III compliance and identical contact finish (gold) on mating surfaces.

Q: What is the significance of the operating temperature difference?

A: The ACT90MG35SN operates from -65°C to 200°C, while the CTVP00RW-21-35JN operates from -65°C to 175°C. The lower upper temperature limit of the Amphenol part represents a 25°C reduction. Applications with sustained operation above 175°C require assessment against actual system thermal profiles to determine if this difference impacts suitability.

Q: Are there differences in contact plating that affect performance?

A: The ACT90MG35SN features 50.0µin (1.27µm) gold plating on mating contacts, while the CTVP00RW-21-35JN features 100.0µin (2.54µm) gold plating. The thicker plating on the Amphenol part provides increased contact durability and may extend service life in applications with frequent mating cycles. Both thicknesses meet MIL-DTL-38999 Series III specifications.

Q: Do both parts have identical environmental protection ratings?

A: Yes. Both the ACT90MG35SN and CTVP00RW-21-35JN are rated as environment resistant and shielded. Both carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no moisture sensitivity constraints during storage or handling.

Q: What is the difference between the shell finishes?

A: The ACT90MG35SN features a nickel shell finish in silver color, while the CTVP00RW-21-35JN features an olive drab cadmium shell finish. Both finishes provide corrosion resistance suitable for aerospace and military applications. Shell finish selection may be driven by system-level color coding or environmental specifications rather than functional performance.

Q: Are both parts compliant with the same regulatory classifications?

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, confirming equivalence for export control and tariff purposes. Both parts are RoHS non-compliant, consistent with military and aerospace connector standards.

Q: What is the current availability status of each part?

A: The ACT90MG35SN is discontinued at DiGi Electronics with 1030 pieces available through original stock channels. The CTVP00RW-21-35JN is active with 1056 pieces in current inventory, providing assured long-term supply chain access for new procurement and maintenance applications.
