Parameter Comparison

Engineering Selection Recommendations

RFSMAA4JCCA (Bulgin): This part is a direct parametric equivalent to the RFSMAA4JAAB, manufactured by the same supplier. Both parts maintain identical electrical, mechanical, and environmental specifications. RFSMAA4JCCA carries ROHS3 Compliance and is Active in product status with 1150 units in inventory, providing increased stock availability.

VC06FS001 (WITHWAVE CO LTD): This part maintains all critical electrical and mechanical parameters required for SMA panel mount compression connector applications. The part is Active in product status with 841 units in inventory. Operating temperature and mating cycle specifications are not provided in the available data. Center contact plating is specified as Gold, differing from the primary part specification.

VC06FS002 (WITHWAVE CO LTD): This part maintains all critical electrical and mechanical parameters required for SMA panel mount compression connector applications. The part is Active in product status with 1012 units in inventory. Operating temperature and mating cycle specifications are not provided in the available data. Center contact plating is specified as Gold, differing from the primary part specification.

All substitute parts are ROHS3 Compliant and classified under ECCN EAR99 and HTSUS 8536.69.4010, consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA4JCCA be used as a direct replacement for RFSMAA4JAAB?

A: Yes. RFSMAA4JCCA is a parametric equivalent manufactured by Bulgin with identical specifications across all electrical, mechanical, and environmental parameters. Both parts are SMA Jack Female Socket connectors rated for 50 Ohms, 26.5 GHz maximum frequency, panel mount flange configuration, and -65°C to 165°C operating temperature range.

Q: What are the differences between Bulgin and WITHWAVE substitute parts?

A: RFSMAA4JCCA is manufactured by Bulgin and maintains complete specification parity with the primary part, including operating temperature (-65°C ~ 165°C), voltage rating (335 V), and mating cycles (500). VC06FS001 and VC06FS002 are manufactured by WITHWAVE CO LTD and maintain all critical electrical and mechanical parameters. Operating temperature, voltage rating, and mating cycle specifications are not provided for the WITHWAVE parts. Both WITHWAVE parts specify Gold center contact plating, whereas the Bulgin parts do not specify plating material.

Q: Are all substitute parts ROHS3 Compliant?

A: RFSMAA4JAAB and RFSMAA4JCCA are explicitly specified as ROHS3 Compliant. RoHS compliance status is not specified in the available data for VC06FS001 and VC06FS002.

Q: What is the maximum frequency rating for all listed parts?

A: All parts listed, including the primary RFSMAA4JAAB and all substitutes, are rated for a maximum frequency of 26.5 GHz.

Q: Do all parts support the same mounting configuration?

A: Yes. All parts are configured for panel mount installation with flange mounting feature and threaded fastening type, ensuring mechanical compatibility in identical mounting applications.

Q: What inventory levels are available for each part?

A: RFSMAA4JAAB: 892 units; RFSMAA4JCCA: 1150 units; VC06FS001: 841 units; VC06FS002: 1012 units.

Q: Are there differences in center contact material specifications?

A: All parts specify Beryllium Copper as the center contact material. Center contact plating is not specified for Bulgin parts (RFSMAA4JAAB and RFSMAA4JCCA). WITHWAVE parts (VC06FS001 and VC06FS002) specify Gold plating for the center contact.
