RF292EJ 2.92mm Coaxial Connector Jack Equivalent & Substitute Parts
Part Overview
The Bulgin RF292EJ is a 2.92mm coaxial connector jack designed for board edge, end launch applications. This female socket connector operates at 50 ohms impedance and supports frequencies up to 40 GHz, making it suitable for high-frequency RF and microwave applications. The connector features compression contact termination with screw shield termination and is rated for 500 mating cycles. The RF292EJ maintains active product status with full RoHS3 compliance and REACH unaffected designation. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific material or performance characteristics are required for particular applications.

Engineering Selection Recommendations
EMPCB.292FST.A.XS (Taoglas Limited) is the primary substitute for RF292EJ. This part maintains full electrical and mechanical compatibility with identical core RF parameters, 500 mating cycle rating, and RoHS3 compliance. The operating temperature range of -55°C to 50°C is narrower than the RF292EJ specification of -55°C to 125°C. Selection of EMPCB.292FST.A.XS is appropriate for applications operating within the -55°C to 50°C temperature envelope. The part features brass body construction with gold plating and gold center contact plating, differing from the RF292EJ stainless steel construction.
SM03FS002, SM03FS003, SM03FS004, and SM03FS005 (WITHWAVE CO LTD) are secondary substitutes. These parts maintain all critical RF and mechanical parameters including 2.92mm connector style, 50 ohms impedance, 40 GHz frequency capability, compression termination, and screw shield termination. These WITHWAVE parts feature stainless steel body construction matching the RF292EJ material specification. Complete operating temperature and mating cycle specifications are not provided in available documentation for these parts. Selection of WITHWAVE substitutes is appropriate when stainless steel body construction is required and when operating conditions fall within standard industrial RF connector ranges.
All identified substitutes maintain RoHS3 compliance status and REACH unaffected designation consistent with the RF292EJ primary part.
Frequently Asked Questions (FAQ)
Q: What are the core electrical parameters that define substitution compatibility for the RF292EJ?
A: The RF292EJ substitutes are defined by 2.92mm connector style, 50 ohms impedance, 40 GHz maximum frequency operation, and jack female socket configuration. All identified substitutes maintain these electrical parameters without deviation.
Q: Can EMPCB.292FST.A.XS be used in applications requiring operation above 50°C?
A: No. The EMPCB.292FST.A.XS operating temperature specification is -55°C to 50°C. Applications requiring operation above 50°C require the RF292EJ or substitutes with extended temperature ratings.
Q: What is the difference between the RF292EJ and EMPCB.292FST.A.XS body materials?
A: The RF292EJ features stainless steel body construction. The EMPCB.292FST.A.XS features brass body construction with gold plating. Both materials are suitable for RF connector applications and maintain equivalent electrical performance at 50 ohms impedance and 40 GHz frequency.
Q: Are the WITHWAVE SM03FS series parts suitable for high-reliability applications?
A: The WITHWAVE SM03FS002, SM03FS003, SM03FS004, and SM03FS005 parts maintain all critical RF and mechanical parameters required for 2.92mm coaxial connector applications. Complete mating cycle and operating temperature specifications are not provided in available documentation. Selection for high-reliability applications requires verification of these parameters against specific application requirements.
Q: Do all substitute parts maintain RoHS3 compliance?
A: The RF292EJ and EMPCB.292FST.A.XS are explicitly specified as RoHS3 compliant. RoHS3 compliance status is not specified in available documentation for the WITHWAVE SM03FS series parts. Applications requiring RoHS3 compliance should prioritize EMPCB.292FST.A.XS or confirm compliance status with WITHWAVE for SM03FS parts.
Q: What is the mating cycle rating for the WITHWAVE substitutes?
A: Mating cycle specifications are not provided in available documentation for SM03FS002, SM03FS003, SM03FS004, and SM03FS005. The RF292EJ and EMPCB.292FST.A.XS are both rated for 500 mating cycles.
Q: Can these 2.92mm connectors be used interchangeably with other connector styles?
A: No. The 2.92mm connector style is specific to these parts. Mechanical and electrical compatibility is limited to 2.92mm connectors. Other connector styles such as 3.5mm, 2.4mm, or 1.85mm are not compatible.
Q: What packaging is available for these coaxial connector parts?
A: All identified parts are supplied in bulk packaging. Specific quantity per package is not specified in available documentation.
