RFSSMAA4JAACFEC Equivalent & Substitute Parts

Part Overview

The RFSSMAA4JAACFEC is an SSMA Connector Jack with female socket configuration, rated for 50 Ohms impedance and designed for panel mount through-hole solder applications. This coaxial RF connector operates across frequencies up to 40 GHz and features a four-hole flange mounting configuration. The part is currently active in production status with 1124 units in stock. Substitute parts are identified to address application requirements where alternative mounting hole configurations or inventory availability necessitate component selection from the qualified equivalent parts list.

Key Parameters

Substitute Part Grouping Explanation

Substitution between RFSSMAA4JAACFEC and RFSSMAA2JCCAFEC is based on electrical and mechanical compatibility within the SSMA connector family. Both parts maintain identical electrical specifications including 50 Ohms impedance, 40 GHz maximum frequency, 335 V voltage rating, and -65°C to 165°C operating temperature range. Both employ solder termination for contact and shield, feature beryllium copper center contacts, stainless steel bodies, and PTFE dielectric material. The primary distinction between these parts is the mounting hole configuration: RFSSMAA4JAACFEC provides four mounting holes while RFSSMAA2JCCAFEC provides two mounting holes. This difference affects only the mechanical mounting interface and does not alter electrical performance or RF characteristics. Both parts are ROHS3 compliant, carry MSL 1 rating, and share the same base product number RFSSMA.

Parameter Comparison

Engineering Selection Recommendations

Both RFSSMAA4JAACFEC and RFSSMAA2JCCAFEC are active production parts with ROHS3 compliance and MSL 1 rating, indicating equivalent regulatory and environmental qualification. Selection between these parts is determined by panel mounting hole requirements. The RFSSMAA4JAACFEC four-hole configuration provides increased mechanical stability and load distribution across the mounting interface, suitable for applications requiring robust panel attachment. The RFSSMAA2JCCAFEC two-hole configuration accommodates panel designs with space constraints or alternative mounting geometries. Both parts maintain identical electrical performance across the full 40 GHz frequency range and identical environmental operating specifications. Component selection should be based on PCB or panel hole pattern compatibility and mechanical mounting requirements rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JCCAFEC be used as a direct replacement for RFSSMAA4JAACFEC?

A: Electrical substitution is valid. Both parts are SSMA female jack connectors with identical 50 Ohms impedance, 40 GHz frequency rating, and solder termination. Mechanical compatibility depends on panel hole pattern. The two-hole configuration of RFSSMAA2JCCAFEC differs from the four-hole configuration of RFSSMAA4JAACFEC, requiring verification that the target panel accommodates the two-hole mounting pattern.

Q: What is the primary difference between these two connector models?

A: The sole difference is the flange mounting hole configuration. RFSSMAA4JAACFEC provides four mounting holes while RFSSMAA2JCCAFEC provides two mounting holes. All electrical parameters, frequency response, impedance, temperature rating, and material specifications are identical.

Q: Are both parts suitable for high-frequency RF applications?

A: Both parts are rated to 40 GHz maximum frequency and maintain 50 Ohms impedance across this range. Both employ PTFE dielectric material and beryllium copper contacts, supporting high-frequency RF signal transmission without performance degradation.

Q: What are the environmental operating conditions for these connectors?

A: Both RFSSMAA4JAACFEC and RFSSMAA2JCCAFEC operate across -65°C to 165°C temperature range with MSL 1 (unlimited moisture sensitivity level) rating, indicating no moisture-related handling restrictions.

Q: Are these parts RoHS compliant?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.

Q: What termination method is used for these connectors?

A: Both parts employ solder termination for both center contact and shield. This requires PCB-level solder attachment during assembly and is not suitable for crimp or push-on applications.
