Engineering Selection Recommendations
Primary Substitute: CTVS06RF-11-98S-506
The CTVS06RF-11-98S-506 manufactured by Amphenol Aerospace Operations is the preferred substitute. This connector maintains all critical mechanical and electrical parameters of the ACT96WB98SN-3025, including 6-position configuration, 11-98 shell size, crimp termination, and threaded fastening. The part is qualified to MIL-DTL-38999 Series III and features an extended operating temperature range of -65°C to 200°C, exceeding the original specification. The CTVS06RF-11-98S-506 is ROHS3 compliant and currently in active production with 2254 units in stock.
Secondary Substitute: D38999/26MB98SN
The D38999/26MB98SN manufactured by Souriau-Sunbank by Eaton provides functional equivalence with identical position count, shell size, and current rating of 7.5A. This connector maintains MIL-DTL-38999 Series III qualification and composite shell construction. The operating temperature range extends to 200°C. However, this part is RoHS non-compliant, matching the original part's compliance status. The D38999/26MB98SN is actively produced with 867 units available.
Tertiary Substitute: D38999/26FB98SN
The D38999/26FB98SN manufactured by Amphenol Aerospace Operations meets all critical substitution parameters with aluminum shell construction and electroless nickel finish. This connector is ROHS3 compliant and qualified to MIL-DTL-38999 Series III with an extended operating temperature range to 200°C. The aluminum shell provides enhanced durability for demanding aerospace and military applications. 872 units are in stock.
Alternative Substitute: D38999/26SB98SN
The D38999/26SB98SN manufactured by Corsair maintains the required 6-position, 11-98 shell size configuration with gold-plated contacts and shielded construction. This connector supports the same crimp termination and threaded fastening. The part is actively produced with 1081 units available. RoHS compliance status matches the original part.
Frequently Asked Questions (FAQ)
Q: Can the CTVS06RF-11-98S-506 directly replace the ACT96WB98SN-3025 in existing assemblies?
A: Yes. The CTVS06RF-11-98S-506 maintains identical connector geometry, position count, shell size, and contact configuration. The threaded fastening and crimp termination are equivalent. The extended operating temperature range of -65°C to 200°C provides additional thermal margin beyond the original -65°C to 175°C specification.
Q: What is the difference between composite and aluminum shell materials in these connectors?
A: Both materials are qualified to MIL-DTL-38999 Series III. Composite shells (ACT96WB98SN-3025, CTVS06RF-11-98S-506, D38999/26MB98SN) provide weight reduction and corrosion resistance. Aluminum shells (D38999/26FB98SN) offer enhanced mechanical strength and thermal conductivity. Selection depends on application-specific requirements for weight, durability, and environmental exposure.
Q: Are there RoHS compliance considerations for substitute selection?
A: The original ACT96WB98SN-3025 is RoHS non-compliant. Substitutes CTVS06RF-11-98S-506 and D38999/26FB98SN are ROHS3 compliant, offering improved environmental compliance for new designs. D38999/26MB98SN and D38999/26SB98SN maintain RoHS non-compliant status, matching the original part's regulatory posture for legacy system maintenance.
Q: Do all substitute parts support the same 7.5A current rating?
A: The ACT96WB98SN-3025 and D38999/26MB98SN are both rated for 7.5A. Current ratings for CTVS06RF-11-98S-506, D38999/26FB98SN, and D38999/26SB98SN are not specified in available documentation. Verify current-carrying requirements with the connector manufacturer for applications exceeding 5A.
Q: What is the significance of the Tri-Start™ TV designation on Amphenol connectors?
A: Tri-Start™ TV is Amphenol's designation for MIL-DTL-38999 Series III connectors meeting military specifications. This designation confirms qualification to the same standard as the original ACT96WB98SN-3025 and ensures mechanical and electrical compatibility.
Q: Can these connectors be intermated with different manufacturers' components?
A: All listed substitutes are qualified to MIL-DTL-38999 Series III with identical shell sizes (11-98, MIL Size B) and contact configurations. Intermating between manufacturers' connectors is supported by the military standard specification. Verify contact size and material compatibility for specific applications.
Q: What packaging options are available for these substitute parts?
A: CTVS06RF-11-98S-506, D38999/26FB98SN, and D38999/26KB98SN are supplied in bulk packaging. D38999/26MB98SN and D38999/26SB98SN are supplied in bag packaging. Packaging selection does not affect connector functionality or performance.
Q: How do operating temperature ranges compare across substitute options?
A: The original ACT96WB98SN-3025 operates from -65°C to 175°C. All primary substitutes (CTVS06RF-11-98S-506, D38999/26FB98SN, D38999/26MB98SN) extend the upper limit to 200°C, providing 25°C additional thermal margin. This extended range supports applications in higher-temperature environments without performance degradation.
