RFSSMAA2JEGD Equivalent & Substitute Parts
Part Overview
The RFSSMAA2JEGD is an SSMA Connector Jack with female socket configuration manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation. This coaxial connector features compression contact termination and screw shield termination, rated for operation across -65°C to 165°C with a maximum frequency of 40 GHz. The part is currently active in production status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part number is unavailable or when alternative mounting configurations are necessary.

Substitute Part Grouping Explanation
Substitute parts for the RFSSMAA2JEGD are identified based on electrical and mechanical parameter equivalence within the SSMA connector family. The substitution logic is structured as follows:
Primary Substitution Criteria:
- Connector style (SSMA)
- Connector type (Jack, Female Socket)
- Impedance (50 Ohms)
- Contact termination method (Compression)
- Shield termination method (Screw)
- Mounting type (Panel Mount)
- Frequency rating (40 GHz maximum)
- Operating temperature range (-65°C ~ 165°C)
- Material composition (Beryllium Copper center contact, Stainless Steel body, PTFE dielectric)
- Compliance status (ROHS3 Compliant)
Secondary Variation Parameters:
- Mounting feature configuration (2-hole flange vs. 4-hole flange)
- Voltage rating (350 V vs. 335 V)
Parts meeting all primary criteria are classified as parametric equivalents. Variations in mounting hole count and minor voltage rating differences represent acceptable substitutions for applications where the mechanical mounting interface and electrical stress requirements align with the substitute part specifications.

Engineering Selection Recommendations
RFSSMAA2JEGA Selection Criteria: The RFSSMAA2JEGA is a direct parametric equivalent to the RFSSMAA2JEGD. Both parts share identical electrical specifications, material composition, and mounting configuration with 2-hole flange mounting. Selection of RFSSMAA2JEGA is appropriate when RFSSMAA2JEGD availability is constrained. Both parts maintain ROHS3 compliance and equivalent performance across the specified frequency and temperature ranges.
RFSSMAA4JCCA Selection Criteria: The RFSSMAA4JCCA is a parametric equivalent with a 4-hole flange mounting configuration in place of the 2-hole design. This part is suitable for applications where panel mounting requires four fastening points. The voltage rating of 335 V on RFSSMAA4JCCA is 15 V lower than the RFSSMAA2JEGD specification of 350 V; selection requires confirmation that the application voltage stress does not exceed 335 V. All other electrical and material parameters remain equivalent. ROHS3 compliance is maintained.
Compliance and Production Status: All three parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment for applications subject to environmental restrictions.
Frequently Asked Questions (FAQ)
Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JEGD?
A: Yes. RFSSMAA2JEGA is a parametric equivalent with identical electrical specifications, material composition, mounting configuration, and compliance status. No design modifications are required for substitution.
Q: What is the primary difference between RFSSMAA2JEGD and RFSSMAA4JCCA?
A: The primary difference is the mounting feature configuration. RFSSMAA2JEGD uses a 2-hole flange mount, while RFSSMAA4JCCA uses a 4-hole flange mount. Additionally, RFSSMAA4JCCA has a voltage rating of 335 V compared to 350 V for RFSSMAA2JEGD. The 4-hole configuration provides additional mechanical stability for applications requiring four fastening points.
Q: Is the 15 V voltage rating difference between RFSSMAA2JEGD (350 V) and RFSSMAA4JCCA (335 V) significant for substitution?
A: The voltage rating difference must be evaluated against the application's maximum operating voltage. If the application operates at or below 335 V, RFSSMAA4JCCA is suitable. If the application requires the full 350 V rating, RFSSMAA4JCCA is not appropriate.
Q: Are all three parts ROHS3 compliant?
A: Yes. RFSSMAA2JEGD, RFSSMAA2JEGA, and RFSSMAA4JCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
Q: What is the maximum operating frequency for these SSMA connectors?
A: All three parts are rated for a maximum frequency of 40 GHz, supporting high-frequency RF applications within this specification.
Q: Can these connectors be used interchangeably in terms of RF performance?
A: Yes, within their respective voltage and mounting specifications. All three parts maintain 50 Ohm impedance, identical dielectric material (PTFE), and equivalent contact materials (Beryllium Copper), ensuring consistent RF performance across the 40 GHz frequency range.
Q: What is the operating temperature range for these connectors?
A: All three parts operate across -65°C to 165°C, providing performance stability across extended temperature environments.
