Engineering Selection Recommendations

CTVPS00RF-11-99SA is the primary substitute for ACT90MB99SA. This part maintains identical contact finish thickness (50.0µin / 1.27µm) and all functional parameters. The connector is manufactured by Amphenol Aerospace Operations with active product status and ROHS3 compliance certification, providing long-term availability and regulatory alignment.

CTVPS00RF-11-99JA is an alternative substitute with identical functional compatibility. This part features increased contact finish thickness (100.0µin / 2.54µm), which provides enhanced durability in high-cycle mating applications. ROHS3 compliance and active product status are maintained.

Both substitute parts eliminate the obsolescence risk associated with the discontinued ACT90MB99SA while maintaining full mechanical and electrical compatibility with existing installations and mating connectors.

Frequently Asked Questions (FAQ)

Q: Are CTVPS00RF-11-99SA and CTVPS00RF-11-99JA fully compatible with ACT90MB99SA?

A: Both parts are functionally and mechanically equivalent. They share identical connector type, position count, shell size, mounting configuration, termination method, and operating temperature range. All critical parameters for mating interface compatibility are identical.

Q: What is the difference between CTVPS00RF-11-99SA and CTVPS00RF-11-99JA?

A: The primary difference is contact finish thickness. CTVPS00RF-11-99SA has 50.0µin (1.27µm) gold plating, matching the original ACT90MB99SA specification. CTVPS00RF-11-99JA has 100.0µin (2.54µm) gold plating, providing increased contact durability. Both maintain identical functional compatibility.

Q: Why is the ACT90MB99SA discontinued?

A: The ACT90MB99SA is discontinued at DiGi Electronics. Amphenol Aerospace Operations maintains active production of functionally equivalent alternatives through the CTVPS00RF series.

Q: Are the substitute parts RoHS compliant?

A: Both CTVPS00RF-11-99SA and CTVPS00RF-11-99JA are ROHS3 compliant. The original ACT90MB99SA is RoHS non-compliant. Substitution provides regulatory compliance improvement for new designs and procurement.

Q: Can I use these connectors interchangeably in existing assemblies?

A: Yes. The substitute parts maintain identical shell size (11-99), mounting feature (flange), fastening type (threaded), and orientation (A). They are directly compatible with existing mating connectors and panel cutouts.

Q: What is the current inventory status?

A: CTVPS00RF-11-99JA has 1266 units in stock. CTVPS00RF-11-99SA has 739 units in stock. Both are available as new original parts.
