Parameter Comparison

Engineering Selection Recommendations

RFSMAA4JCCA (Bulgin): This part is a parametric equivalent to the RFSMAA4JAAC, manufactured by the same supplier. Both parts share identical electrical and mechanical specifications, including operating temperature range (-65°C ~ 165°C), voltage rating (335 V), and mating cycle rating (500). Both are ROHS3 compliant with MSL rating of 1. This substitute provides direct interchangeability with equivalent performance characteristics and is suitable for applications requiring identical specifications.

VC06FS001 (WITHWAVE CO LTD): This connector maintains all critical electrical and mechanical parameters including SMA style, 50-ohm impedance, 26.5 GHz frequency capability, compression contact termination, and screw shield termination. The part features gold-plated center contacts. Operating temperature, voltage rating, and mating cycle specifications are not provided in the available data. This part is suitable for applications where the core RF and mechanical interface requirements are the primary selection criteria.

VC06FS002 (WITHWAVE CO LTD): This connector is functionally equivalent to VC06FS001, maintaining all specified electrical and mechanical parameters with gold-plated center contacts. Operating temperature, voltage rating, and mating cycle specifications are not provided. This part is suitable for applications where the core RF and mechanical interface requirements are the primary selection criteria.

All substitute parts are active products with current inventory availability and maintain compliance with applicable standards and regulations.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA4JCCA be used as a direct replacement for RFSMAA4JAAC?

A: Yes. RFSMAA4JCCA is a parametric equivalent manufactured by Bulgin with identical electrical specifications (50 ohms, 26.5 GHz maximum frequency), mechanical configuration (SMA jack, female socket, panel mount flange), contact termination (compression), and environmental ratings (-65°C ~ 165°C operating temperature, 335 V voltage rating, 500 mating cycles). Both parts are ROHS3 compliant with MSL rating 1.

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

A: The Bulgin substitute (RFSMAA4JCCA) provides complete specification matching including operating temperature range, voltage rating, and mating cycle specifications. The WITHWAVE parts (VC06FS001 and VC06FS002) maintain all critical RF and mechanical interface parameters but do not provide operating temperature, voltage rating, or mating cycle data in the available specifications. Both WITHWAVE parts feature gold-plated center contacts compared to unspecified plating on the Bulgin parts.

Q: Are the WITHWAVE connectors (VC06FS001 and VC06FS002) suitable for high-temperature applications?

A: Operating temperature specifications are not provided for the WITHWAVE parts. The RFSMAA4JAAC and RFSMAA4JCCA are rated for -65°C ~ 165°C operation. For applications requiring confirmed high-temperature performance, the Bulgin parts with specified temperature ratings are the appropriate selection.

Q: What is the significance of gold plating on the WITHWAVE connectors?

A: The WITHWAVE parts (VC06FS001 and VC06FS002) feature gold-plated center contacts. The center contact plating specification is not provided for the Bulgin parts. Gold plating provides enhanced corrosion resistance and contact reliability. The selection between gold-plated and unspecified plating depends on application environmental requirements and contact durability expectations.

Q: Can these connectors be used interchangeably in the same application?

A: All four parts maintain identical SMA connector style, female socket configuration, 50-ohm impedance, 26.5 GHz frequency capability, compression contact termination, and screw shield termination. Mechanical compatibility is ensured through matching panel mount flange configuration with threaded fastening. Interchangeability is supported for applications where the specified electrical and mechanical parameters are the primary requirements. Applications with specific environmental or performance requirements should reference the complete specification data for each part.

Q: What inventory levels are available for each part?

A: RFSMAA4JAAC: 1151 pieces in stock; RFSMAA4JCCA: 1150 pieces in stock; VC06FS001: 841 pieces in stock; VC06FS002: 1012 pieces in stock. All parts are available in bulk packaging.
