Parameter Comparison

Engineering Selection Recommendations

RFSMAA4JCCA (Bulgin): This substitute maintains complete electrical and mechanical equivalence to the RFSMAA2JEGC. The primary design difference is the mounting flange configuration, which changes from 2-hole to 4-hole mounting. Both parts share identical impedance, frequency rating, operating temperature range, voltage rating, and mating cycle specifications. Both are ROHS3 Compliant with MSL 1 rating. This part is suitable for direct substitution where panel mounting hole patterns accommodate the 4-hole flange design.

VC06FS001 (WITHWAVE CO LTD): This substitute maintains electrical equivalence across all critical RF parameters including 50 Ohm impedance, 26.5 GHz maximum frequency, compression contact termination, and screw shield termination. The connector features gold-plated center contacts. Operating temperature, mating cycle specifications, and RoHS compliance status are not provided in the available data. This part is suitable for substitution in applications where center contact plating material differences are acceptable.

VC06FS002 (WITHWAVE CO LTD): This substitute maintains electrical equivalence across all critical RF parameters including 50 Ohm impedance, 26.5 GHz maximum frequency, compression contact termination, and screw shield termination. The connector features gold-plated center contacts. Operating temperature, mating cycle specifications, and RoHS compliance status are not provided in the available data. This part is suitable for substitution in applications where center contact plating material differences are acceptable.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the RFSMAA2JEGC?

A: Substitute parts must maintain identical SMA connector style, jack female socket type, 50 Ohm impedance, compression contact termination, screw shield termination, panel mount configuration with flange, threaded fastening, and 26.5 GHz maximum frequency rating. All substitute parts listed meet these core electrical and mechanical requirements.

Q: What is the primary difference between RFSMAA2JEGC and RFSMAA4JCCA?

A: Both parts are manufactured by Bulgin and share identical electrical specifications and operating parameters. The difference is in the mounting flange design: RFSMAA2JEGC features a 2-hole flange mount, while RFSMAA4JCCA features a 4-hole flange mount. Selection depends on the panel mounting hole pattern in your application.

Q: How do the WITHWAVE parts (VC06FS001 and VC06FS002) differ from the Bulgin parts?

A: The WITHWAVE parts maintain electrical equivalence in impedance, frequency rating, connector type, and termination methods. The primary difference is center contact plating: WITHWAVE parts feature gold plating, while the Bulgin RFSMAA2JEGC does not specify plating material. Operating temperature range, mating cycle count, and RoHS compliance details are not provided for WITHWAVE parts in the available specifications.

Q: Can I use VC06FS001 or VC06FS002 in place of RFSMAA2JEGC without additional testing?

A: Both WITHWAVE parts maintain the critical electrical parameters required for SMA 50 Ohm RF applications at frequencies up to 26.5 GHz. However, operating temperature range, mating cycle specifications, and environmental compliance certifications differ in available documentation. Application-specific requirements should be evaluated before selection.

Q: Are all substitute parts RoHS3 compliant?

A: RFSMAA2JEGC and RFSMAA4JCCA are both explicitly ROHS3 Compliant. RoHS compliance status for VC06FS001 and VC06FS002 is not specified in the available data.

Q: What is the inventory status for each part?

A: RFSMAA2JEGC: 966 units in stock; RFSMAA4JCCA: 1150 units in stock; VC06FS001: 841 units in stock; VC06FS002: 1012 units in stock. All parts are listed as Active product status.

Q: Do all parts support the same operating temperature range?

A: RFSMAA2JEGC and RFSMAA4JCCA both operate from -65°C to 165°C. Operating temperature specifications for VC06FS001 and VC06FS002 are not provided in the available data.
