RFSMAEJ SMA Connector Jack Equivalent & Substitute Parts
Part Overview
The RFSMAEJ is an SMA Connector Jack, Female Socket manufactured by Bulgin, designed for board edge end launch applications in 50 Ohm RF systems. This coaxial connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures from -55°C to 155°C. The connector features compression contact termination with screw shield termination and is constructed from stainless steel with beryllium copper center contacts. The RFSMAEJ maintains Active product status and is RoHS3 compliant with REACH Unaffected classification.
Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the SMA connector jack category, specifically for board edge end launch configurations with identical impedance, contact termination, and mounting specifications.

Engineering Selection Recommendations
All substitute parts maintain Active product status and are suitable for direct substitution in applications requiring SMA connector jacks with board edge end launch configuration and 50 Ohm impedance up to 26.5 GHz.
The RFSMAEJ is RoHS3 compliant and REACH unaffected. Compliance documentation should be verified for the substitute parts when regulatory requirements are specified in the application.
The RFSMAEJ specifies operating temperature range of -55°C to 155°C and mating cycle rating of 500 cycles. Substitute parts from WITHWAVE CO LTD do not provide published operating temperature or mating cycle specifications in the available data. Applications requiring documented thermal performance or cycle life specifications should reference the RFSMAEJ or obtain detailed specifications from the substitute manufacturer.
Dielectric material differs between the main part (Polyetherimide) and substitute parts (Polytetrafluoroethylene). Both materials are suitable for RF applications at the specified frequency range. Center contact plating is specified as Gold for all substitute parts, while the main part does not specify plating material.
All parts are packaged in Bulk format and carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.
Frequently Asked Questions (FAQ)
Q: Can SM06FS001, SM06FS002, SM06FS003, SM06FS004, or SM06FS005 be used as direct replacements for RFSMAEJ?
A: Yes. All substitute parts maintain identical electrical and mechanical parameters across connector style, type, impedance, frequency rating, mounting configuration, contact termination, and body materials. Direct substitution is valid for applications where the specified parameters are the primary selection criteria.
Q: What is the difference between the RFSMAEJ and the WITHWAVE substitute parts?
A: The primary differences are dielectric material (Polyetherimide versus Polytetrafluoroethylene) and center contact plating specification (not specified versus Gold). Both dielectric materials are suitable for RF applications at 26.5 GHz. The substitute parts specify Gold plating on center contacts, while the RFSMAEJ does not specify plating material.
Q: Are operating temperature and mating cycle specifications available for the substitute parts?
A: Operating temperature and mating cycle specifications are not provided in the available data for the WITHWAVE substitute parts. The RFSMAEJ specifies -55°C to 155°C operating temperature and 500 mating cycles. Applications with specific thermal or cycle life requirements should obtain detailed specifications from WITHWAVE CO LTD or select the RFSMAEJ.
Q: Do all parts carry the same regulatory compliance?
A: The RFSMAEJ is RoHS3 compliant and REACH unaffected. Regulatory compliance status for the WITHWAVE substitute parts is not specified in the available data. Compliance documentation should be obtained from the manufacturer when regulatory requirements are specified.
Q: Are there inventory differences between the main part and substitutes?
A: Yes. RFSMAEJ inventory is 827 pieces. WITHWAVE substitute inventory ranges from 702 to 1159 pieces across the five part numbers. Inventory availability should be confirmed with the supplier for production requirements.
Q: What is the significance of the different part numbers (SM06FS001 through SM06FS005)?
A: The substitute parts are listed as separate part numbers by WITHWAVE CO LTD. Specific differentiation between these part numbers is not provided in the available data. The manufacturer should be consulted to determine if these represent different configurations, revisions, or manufacturing variants.
