Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MB98SN is determined by strict adherence to MIL-DTL-38999 Series III specifications. All substitute parts must maintain identical mechanical and electrical compatibility through the following critical parameters:

Mechanical Compatibility:

• 6-position configuration
• Shell size 11-98
• Panel mount flange orientation
• Threaded fastening
• Normal (N) orientation

Electrical Compatibility:

• Female socket receptacle type
• Crimp termination method
• Shielded design
• Gold-plated mating contacts
• Copper alloy contact material
• Thermoplastic insert material
• Environment resistant ingress protection

Operational Compatibility:

• Operating temperature range capability
• Current rating capacity
• MIL-DTL-38999 Series III compliance

The substitute parts CTVP00RW-11-98JN and CTVPS00RF-11-98JN satisfy these mechanical and electrical requirements while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

CTVPS00RF-11-98JN is the primary substitute for ACT90MB98SN. This part maintains full mechanical and electrical compatibility while offering the following advantages:

• Active product status with confirmed inventory availability
• Operating temperature range identical to the original part (-65°C ~ 200°C)
• RoHS3 compliance for regulatory alignment with modern procurement standards
• Electroless nickel shell finish providing enhanced corrosion resistance
• Silver color matching the original part aesthetic
• Increased contact finish thickness (100.0µin vs. 50.0µin) for improved durability
• MIL-DTL-38999 Series III Tri-Start™ TV series certification

CTVP00RW-11-98JN serves as a secondary substitute option. This part provides full mechanical and electrical compatibility with the following considerations:

• Active product status with high inventory availability
• Operating temperature range of -65°C ~ 175°C, which is 25°C lower than the original specification
• RoHS non-compliant status matching the original part
• Olive Drab Cadmium shell finish differing from the original silver finish
• Increased contact finish thickness (100.0µin vs. 50.0µin)
• MIL-DTL-38999 Series III Tri-Start™ TV series certification

Selection between CTVPS00RF-11-98JN and CTVP00RW-11-98JN depends on application-specific requirements regarding operating temperature limits, RoHS compliance mandates, and shell finish specifications.

Frequently Asked Questions (FAQ)

Q: Can CTVPS00RF-11-98JN directly replace ACT90MB98SN in existing assemblies?

A: Yes. Both connectors conform to MIL-DTL-38999 Series III specifications with identical mechanical interfaces (6-position, 11-98 shell size, panel mount flange, threaded fastening) and electrical characteristics (female socket receptacles, crimp termination, shielded design, gold-plated contacts, copper alloy contacts). The connectors are mechanically and electrically interchangeable.

Q: What is the significance of the contact finish thickness difference?

A: The substitute parts feature 100.0µin (2.54µm) gold plating compared to the original part's 50.0µin (1.27µm). Increased plating thickness provides enhanced durability and extended service life in high-cycle mating applications, representing an improvement over the original specification.

Q: Why does CTVP00RW-11-98JN have a lower operating temperature maximum?

A: CTVP00RW-11-98JN operates to -65°C ~ 175°C, which is 25°C lower than the original ACT90MB98SN specification of -65°C ~ 200°C. Applications requiring operation at temperatures exceeding 175°C must use CTVPS00RF-11-98JN, which maintains the full -65°C ~ 200°C range.

Q: What is the difference between Olive Drab Cadmium and Electroless Nickel finishes?

A: CTVP00RW-11-98JN features Olive Drab Cadmium shell finish, while CTVPS00RF-11-98JN features Electroless Nickel finish. Both provide corrosion resistance suitable for aerospace and military applications. Shell finish selection depends on application-specific environmental exposure and aesthetic requirements. The original ACT90MB98SN used Nickel finish, making CTVPS00RF-11-98JN the closer match.

Q: Are there RoHS compliance implications for substitution?

A: The original ACT90MB98SN is RoHS non-compliant. CTVP00RW-11-98JN maintains RoHS non-compliant status. CTVPS00RF-11-98JN is RoHS3 compliant. Applications subject to RoHS3 regulatory requirements must use CTVPS00RF-11-98JN. Applications without RoHS mandates may use either substitute.

Q: How do the Tri-Start™ TV series designations affect compatibility?

A: Both substitute parts belong to the MIL-DTL-38999 Series III Tri-Start™ TV series, which is a variant within the broader Series III standard. This designation indicates compatibility with Series III connector systems while offering specific design features of the Tri-Start™ TV product line. Compatibility with existing Series III mating plugs and assemblies is maintained.

Q: What inventory considerations apply to these substitutes?

A: ACT90MB98SN is discontinued with 900 pieces in stock. CTVP00RW-11-98JN is active with 1180 pieces available. CTVPS00RF-11-98JN is active with 892 pieces available. Both substitutes offer active product status with confirmed ongoing availability, addressing the discontinuation of the original part.
