Both parts support identical frequency ranges up to 26.5 GHz and operating temperature ranges from -65°C to 165°C, ensuring functional interchangeability in RF coaxial connector applications.

Frequently Asked Questions (FAQ)

Q: Are RFSMAAJB and RFSMAAJA directly interchangeable?

A: Yes. Both parts are identical across all provided electrical, mechanical, and environmental parameters. They share the same SMA connector style, 50 Ohm impedance, panel mount bulkhead configuration, solder termination, frequency rating of 26.5 GHz, and operating temperature range of -65°C to 165°C.

Q: What determines substitution eligibility for SMA coaxial connectors?

A: Substitution eligibility is determined by matching connector style, connector type (jack/female socket), impedance (50 Ohms), mounting type (panel mount), mounting feature (bulkhead), contact and shield termination methods (solder), frequency rating, voltage rating, operating temperature range, and compliance certifications (ROHS3).

Q: Can these connectors be used in applications requiring frequencies above 26.5 GHz?

A: No. Both RFSMAAJB and RFSMAAJA are rated for a maximum frequency of 26.5 GHz. Applications requiring higher frequency operation require alternative connector specifications.

Q: What is the significance of the 500 mating cycles rating?

A: The 500 mating cycles specification indicates the mechanical durability of the connector interface. Both parts support 500 connection and disconnection cycles before potential degradation of electrical or mechanical performance.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both RFSMAAJB and RFSMAAJA support operating temperatures from -65°C to 165°C, making them suitable for applications across this temperature range.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance indicates that both parts meet Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment.

Q: Is there a difference in packaging between these two part numbers?

A: Both parts are supplied in Bulk packaging. No packaging differences exist between RFSMAAJB and RFSMAAJA.
