Engineering Selection Recommendations
Primary Substitute: RFSMAA4JCCA (Bulgin)
The RFSMAA4JCCA represents the closest functional equivalent to the RFSMAA4JAAA. Both parts are manufactured by Bulgin and share identical electrical and mechanical specifications across all documented parameters. Both maintain Active product status and RoHS3 compliance. The RFSMAA4JCCA is suitable for direct substitution in applications where Bulgin component continuity is preferred or required by design specifications.
Alternative Substitutes: VC06FS001 and VC06FS002 (WITHWAVE CO LTD)
The VC06FS001 and VC06FS002 connectors manufactured by WITHWAVE CO LTD provide functional equivalence based on matching core RF and mechanical parameters: SMA connector style, female socket jack configuration, 50 Ohms impedance, 26.5 GHz maximum frequency, compression contact termination, screw shield termination, panel mount flange configuration, and threaded fastening. Both parts feature beryllium copper center contacts and stainless steel bodies with gold plating on center contacts.
The VC06FS001 and VC06FS002 do not specify operating temperature range, voltage rating, or mating cycle ratings in the provided documentation. Selection of these alternatives is appropriate when component sourcing from alternative manufacturers is acceptable and when the application environment does not require explicit validation of temperature or voltage specifications beyond the SMA standard.
Compliance Considerations:
All four parts maintain compliance with ECCN EAR99 and HTSUS 8536.69.4010 classifications. The Bulgin parts (RFSMAA4JAAA and RFSMAA4JCCA) provide documented RoHS3 compliance and MSL 1 rating. Component selection should align with procurement specifications and supply chain requirements.
Frequently Asked Questions (FAQ)
Q: Can RFSMAA4JCCA be used as a direct replacement for RFSMAA4JAAA?
A: Yes. The RFSMAA4JCCA is a parametric equivalent with identical electrical specifications (50 Ohms, 26.5 GHz maximum frequency, compression termination), mechanical mounting configuration (panel mount flange with threaded fastening), and environmental ratings (-65°C to 165°C operating temperature, 335 V voltage rating). Both parts are manufactured by Bulgin and maintain RoHS3 compliance.
Q: What are the differences between Bulgin and WITHWAVE substitute parts?
A: The Bulgin parts (RFSMAA4JAAA and RFSMAA4JCCA) provide complete specification documentation including operating temperature range (-65°C ~ 165°C), voltage rating (335 V), mating cycle rating (500 cycles), and RoHS3 compliance certification. The WITHWAVE parts (VC06FS001 and VC06FS002) match all critical RF and mechanical parameters but do not specify operating temperature, voltage rating, or mating cycle performance in the provided data. Both manufacturers' parts share identical connector style, impedance, frequency rating, and contact materials.
Q: Are the WITHWAVE VC06FS001 and VC06FS002 interchangeable with each other?
A: Yes. Both WITHWAVE parts share identical electrical and mechanical specifications. Selection between VC06FS001 and VC06FS002 may be determined by inventory availability or specific procurement requirements, as both provide equivalent RF performance and mechanical compatibility.
Q: What mounting hardware is required for installation?
A: All four substitute parts feature flange-mounted design with threaded fastening. The RFSMAA4JAAA documentation specifies four mounting holes. Installation requires threaded fasteners appropriate for the panel thickness and material. Screw shield termination is standard across all parts.
Q: Can these connectors be used in high-frequency applications above 20 GHz?
A: Yes. All four substitute parts are rated for maximum frequency of 26.5 GHz, supporting RF applications across the full SMA operating bandwidth including millimeter-wave frequencies up to 26.5 GHz.
Q: What is the significance of the compression contact termination?
A: Compression termination provides mechanical and electrical connection to the cable conductor without soldering. This contact method is standard for SMA connectors and is consistent across all four substitute parts, ensuring equivalent signal integrity and connection reliability.
Q: Are there any environmental restrictions for these connectors?
A: The Bulgin parts (RFSMAA4JAAA and RFSMAA4JCCA) are rated for operating temperatures from -65°C to 165°C and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related handling restrictions. The WITHWAVE parts do not specify environmental ratings in the provided documentation.
