Substitute Part Grouping Explanation
The RFSSMAA2JEGA and RFSSMAA4JCCA are functionally equivalent SSMA coaxial connectors within the same product family. Both parts share identical electrical and RF characteristics including 50 Ohms impedance, 40 GHz maximum frequency, compression contact termination, and screw shield termination. The primary distinction between these parts is the mounting feature configuration: the RFSSMAA2JEGA utilizes a 2-hole flange mount, while the RFSSMAA4JCCA utilizes a 4-hole flange mount. This difference affects only the mechanical panel mounting interface and does not impact electrical performance or RF specifications. Both parts maintain identical operating temperature ranges (-65°C ~ 165°C), mating cycle ratings (500 cycles), and RoHS3 compliance status. The substitution is valid when the target application accommodates the alternative mounting hole configuration.

Engineering Selection Recommendations
Both RFSSMAA2JEGA and RFSSMAA4JCCA are Active products manufactured by Bulgin with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts is determined by panel mounting hole configuration requirements. The RFSSMAA2JEGA is specified for applications requiring 2-hole flange mounting, while the RFSSMAA4JCCA accommodates 4-hole flange mounting. The voltage rating differential (350 V versus 335 V) is negligible for most RF applications and does not constitute a limiting factor in substitution decisions. Both parts maintain identical RF performance characteristics, operating temperature ranges, and mating cycle specifications. Component selection should be based on the mechanical panel interface design of the target application.
Frequently Asked Questions (FAQ)
Q: Can RFSSMAA4JCCA be used as a direct replacement for RFSSMAA2JEGA?
A: Electrical and RF substitution is valid. The RFSSMAA4JCCA provides identical 50 Ohms impedance, 40 GHz frequency capability, and compression termination. Mechanical compatibility depends on panel hole configuration. If the application panel is designed for 2-hole mounting, the 4-hole variant requires panel modification or adapter hardware.
Q: What is the primary difference between these two part numbers?
A: The mounting feature configuration differs. RFSSMAA2JEGA uses a 2-hole flange mount, while RFSSMAA4JCCA uses a 4-hole flange mount. All electrical, RF, and environmental specifications remain identical.
Q: Are both parts RoHS compliant?
A: Yes, both RFSSMAA2JEGA and RFSSMAA4JCCA are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
Q: What is the maximum operating frequency for both connectors?
A: Both parts are rated for maximum frequency operation up to 40 GHz.
Q: Do these connectors support the same mating cycle count?
A: Yes, both parts are rated for 500 mating cycles.
Q: What temperature range do these connectors support?
A: Both RFSSMAA2JEGA and RFSSMAA4JCCA operate across the temperature range of -65°C to 165°C.
Q: Is there a significant difference in voltage rating between the two parts?
A: The RFSSMAA2JEGA is rated at 350 V while the RFSSMAA4JCCA is rated at 335 V. This 15 V differential is not significant for typical RF coaxial connector applications.
Q: What materials are used in the connector construction?
A: Both parts feature stainless steel bodies, beryllium copper center contacts, and PTFE dielectric material.
