Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MH35SN is determined by strict equivalence across the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle with female sockets
• Position count: 100 positions
• Shell size: 23-35 insert designation
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening: Threaded
• Orientation: Normal (N)
• Shell material: Composite
• Contact finish: Gold plating on mating surfaces
• Shielding: Shielded construction
• Series compliance: MIL-DTL-38999 Series III

Secondary Compatibility Parameters:

• Operating temperature range
• Contact material composition
• Shell finish specifications
• RoHS compliance status

The substitute parts listed maintain equivalence across all primary criteria. Variations in secondary parameters such as shell finish (nickel versus electroless nickel versus cadmium), operating temperature upper limits, and RoHS compliance status are noted for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

CTVPS00RF-23-35JN is the primary substitute for ACT90MH35SN. This part maintains full functional equivalence across all critical parameters, including the complete operating temperature range of -65°C to 200°C. CTVPS00RF-23-35JN is currently in active production status with 938 units in stock. The part achieves ROHS3 compliance, providing regulatory advantage for new system designs and procurement cycles. The electroless nickel shell finish and increased contact finish thickness (100.0µin versus 50.0µin) provide enhanced corrosion resistance and contact durability compared to the original part.

CTVP00RW-23-35JN serves as an alternative substitute with equivalent mechanical and electrical characteristics. This part operates within a reduced temperature range (-65°C to 175°C), which is suitable for applications not requiring the full 200°C upper limit of the original ACT90MH35SN. CTVP00RW-23-35JN features olive drab cadmium shell finish and is available in active production status with 1173 units in stock. This part remains RoHS non-compliant.

Housing-Only Alternatives: CTVP00RW-23-35JN-LC and CTVPS00RF-23-35JN-LC are receptacle housing components without integrated contacts. These parts are suitable for applications requiring separate contact procurement and assembly. CTVPS00RF-23-35JN-LC maintains the full -65°C to 200°C operating range and ROHS3 compliance.

For applications requiring the original operating temperature specification of -65°C to 200°C, CTVPS00RF-23-35JN is the recommended selection. For applications with reduced temperature requirements, CTVP00RW-23-35JN provides equivalent functionality with established production availability.

Frequently Asked Questions (FAQ)

Q: Can CTVPS00RF-23-35JN directly replace ACT90MH35SN in existing assemblies?

A: Yes. Both connectors maintain identical mechanical interfaces (panel mount flange, threaded fastening, 100-position 23-35 shell size) and electrical characteristics (crimp termination, gold-plated copper alloy contacts, shielded construction). Physical mounting and mating with existing cable assemblies is compatible.

Q: What is the significance of the contact finish thickness difference between ACT90MH35SN (50.0µin) and CTVPS00RF-23-35JN (100.0µin)?

A: The increased contact finish thickness in CTVPS00RF-23-35JN provides extended service life through enhanced resistance to wear and corrosion. This thicker gold plating maintains contact integrity across repeated mating cycles and environmental exposure, particularly in aerospace and military applications.

Q: Why does CTVP00RW-23-35JN have a lower operating temperature maximum (175°C versus 200°C)?

A: The temperature rating reflects the thermal design specifications of the Tri-Start™ TV series connector housing and insert materials. Applications operating above 175°C require CTVPS00RF-23-35JN to ensure material stability and electrical performance.

Q: Is ROHS3 compliance required for my application?

A: ROHS3 compliance is mandatory for products sold into European Union markets and many aerospace supply chains. CTVPS00RF-23-35JN meets ROHS3 requirements, while ACT90MH35SN and CTVP00RW-23-35JN do not. Verify regulatory requirements for your specific application and end-use market.

Q: What is the difference between CTVPS00RF-23-35JN and CTVPS00RF-23-35JN-LC?

A: CTVPS00RF-23-35JN is a complete connector receptacle with integrated female socket contacts. CTVPS00RF-23-35JN-LC is a housing-only component without contacts included. The housing-only variant is used when contacts are procured separately or when existing contacts require reuse.

Q: Are the shell finish variations (nickel, cadmium, electroless nickel) interchangeable?

A: Shell finish variations are mechanically and electrically interchangeable. Selection depends on environmental exposure requirements and corrosion resistance specifications. Electroless nickel (CTVPS00RF series) provides superior corrosion resistance in harsh environments. Cadmium (CTVP00RW series) offers established aerospace heritage. Nickel (ACT90MH35SN) provides baseline protection.

Q: What inventory status should I consider for procurement?

A: ACT90MH35SN is discontinued and no longer available through DiGi Electronics. CTVPS00RF-23-35JN (938 units), CTVP00RW-23-35JN (1173 units), and housing variants maintain active production status with current stock availability. For new designs and long-term supply assurance, specify CTVPS00RF-23-35JN or CTVP00RW-23-35JN.
