RFSSMAA4JCCD Equivalent & Substitute Parts

Part Overview

The RFSSMAA4JCCD is an SSMA Connector Jack with female socket configuration, manufactured by Bulgin for RF coaxial applications. This panel mount connector features compression contact termination and screw shield termination, rated for 50 Ohms impedance and operation up to 40 GHz. The part is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, specific mounting hole configurations, or voltage rating requirements while maintaining electrical and mechanical compatibility within the SSMA connector family.

Engineering Selection Recommendations

All three parts—RFSSMAA4JCCD, RFSSMAA4JCCA, and RFSSMAA2JEGA—are active products manufactured by Bulgin with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by mechanical mounting requirements and voltage rating specifications.

RFSSMAA4JCCD and RFSSMAA4JCCA are functionally equivalent with 4-hole flange mounting configurations and 335 V voltage rating. These parts are interchangeable for applications requiring four-point panel mount fastening.

RFSSMAA2JEGA provides a 2-hole flange mounting configuration with a 350 V voltage rating. This part is suitable for applications with two-point panel mount fastening requirements or where the higher voltage rating is specified.

Selection should be based on panel cutout design and mounting hole spacing. All parts maintain identical RF performance characteristics, impedance matching, and thermal operating specifications.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA4JCCD?

A: RFSSMAA2JEGA is electrically equivalent but differs in mounting hole configuration. The main part features a 4-hole flange, while RFSSMAA2JEGA features a 2-hole flange. Direct substitution is possible only if the panel cutout and fastening design accommodate the 2-hole configuration.

Q: What is the difference between RFSSMAA4JCCD and RFSSMAA4JCCA?

A: Both parts share identical electrical and mechanical specifications, including 4-hole flange mounting and 335 V voltage rating. The parts are functionally interchangeable with no performance differences.

Q: Does the voltage rating difference between RFSSMAA4JCCD (335 V) and RFSSMAA2JEGA (350 V) affect RF performance?

A: Voltage rating does not affect RF performance, impedance, or frequency response. The voltage rating specifies the maximum electrical potential the connector can withstand. Selection should be based on application voltage requirements and mounting hole configuration.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSSMAA4JCCD, RFSSMAA4JCCA, and RFSSMAA2JEGA are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What determines whether a substitute part is compatible?

A: Compatibility is determined by matching connector style (SSMA), connector type (Jack, Female Socket), impedance (50 Ohms), contact termination (Compression), shield termination (Screw), frequency rating (40 GHz), and operating temperature range (-65°C ~ 165°C). Mounting hole configuration and voltage rating may vary based on application requirements.

Q: Can these connectors be used interchangeably in high-frequency applications?

A: Yes. All three parts are rated to 40 GHz with identical impedance (50 Ohms), dielectric material (PTFE), and center contact material (Beryllium Copper). RF performance is equivalent across all three part numbers.
