Engineering Selection Recommendations
Primary Substitute: CTVS06RF-11-98S-506
The CTVS06RF-11-98S-506 manufactured by Amphenol Aerospace Operations is the recommended primary substitute. This connector maintains full electrical and mechanical compatibility with the ACT96MB98SN across all critical parameters: 6-position configuration, 11-98 shell size, crimp termination, threaded fastening, gold-plated contacts at 50.0µin thickness, shielded design, and -65°C to 200°C operating range. The part is currently active in production with 2254 units in stock. ROHS3 compliance provides regulatory advantage for new system designs and procurement cycles.
Secondary Substitute: D38999/26FB98SN
The D38999/26FB98SN manufactured by Amphenol Aerospace Operations provides an alternative with aluminum shell construction instead of composite. This variant maintains MIL-DTL-38999 Series III qualification and all electrical parameters. The aluminum shell offers enhanced mechanical durability and environmental protection. ROHS3 compliance and active production status support long-term availability. Current inventory: 872 units.
Tertiary Substitute: D38999/26MB98SN
The D38999/26MB98SN manufactured by Souriau-Sunbank by Eaton is functionally equivalent with composite shell construction matching the original ACT96MB98SN. This part provides IP67 ingress protection (dust tight, waterproof) exceeding the environment-resistant rating of the original. Current inventory: 867 units. RoHS non-compliance status aligns with the original part specification.
Alternative Substitute: D38999/26SB98SN
The D38999/26SB98SN manufactured by Corsair maintains full mechanical and electrical compatibility. This connector is currently active with 1081 units in stock. RoHS non-compliance status matches the original part. Selection of this variant should be based on procurement availability and supply chain requirements.
Frequently Asked Questions (FAQ)
Q: Can CTVS06RF-11-98S-506 directly replace ACT96MB98SN in existing assemblies?
A: Yes. Both connectors maintain identical mechanical interfaces (11-98 shell size, threaded fastening, free-hanging in-line mounting) and electrical specifications (6 positions, crimp termination, gold-plated contacts, 7.5A current capacity, -65°C to 200°C operating range). Physical mating and functional performance are equivalent.
Q: What is the difference between composite and aluminum shell variants?
A: Composite-shell variants (ACT96MB98SN, CTVS06RF-11-98S-506, D38999/26MB98SN) provide lightweight construction suitable for weight-sensitive applications. Aluminum-shell variants (D38999/26FB98SN) offer enhanced mechanical strength and thermal conductivity. Both maintain MIL-DTL-38999 Series III qualification and equivalent electrical performance. Selection depends on application-specific mechanical and thermal requirements.
Q: Does RoHS3 compliance affect electrical performance?
A: No. RoHS3 compliance addresses material composition and hazardous substance restrictions but does not alter electrical or mechanical performance. CTVS06RF-11-98S-506 and D38999/26FB98SN are ROHS3 compliant and maintain identical electrical specifications to the original ACT96MB98SN.
Q: Are all substitute parts qualified to MIL-DTL-38999 Series III?
A: Yes. All recommended substitutes (CTVS06RF-11-98S-506, D38999/26FB98SN, D38999/26MB98SN, D38999/26SB98SN) are qualified to MIL-DTL-38999 Series III, ensuring compliance with military and aerospace specifications.
Q: What is the significance of 50.0µin (1.27µm) contact finish thickness?
A: This specification defines the gold plating thickness on mating contacts. All substitute parts maintain this identical thickness, ensuring equivalent contact resistance, wear characteristics, and long-term reliability in mating cycles.
Q: Can I mix composite and aluminum shell connectors in the same system?
A: Mechanical and electrical compatibility exists between composite and aluminum variants due to standardized shell sizing (11-98) and contact specifications. System-level integration decisions should consider thermal management, weight distribution, and environmental exposure requirements specific to the application.
Q: What inventory levels support procurement decisions?
A: CTVS06RF-11-98S-506 offers the highest current inventory (2254 units), followed by D38999/26SB98SN (1081 units), D38999/26MB98SN (867 units), and D38999/26FB98SN (872 units). Inventory levels support both immediate procurement and long-term supply chain planning for aerospace and military applications.
Q: Is the IP67 rating of D38999/26MB98SN a functional upgrade?
A: IP67 (dust tight, waterproof) provides enhanced environmental protection compared to the environment-resistant rating of the original ACT96MB98SN. This represents an improvement in ingress protection capability without altering core electrical or mechanical specifications. Selection should be based on application environmental exposure requirements.
