RFSSMAA4JCCA Equivalent & Substitute Parts
Part Overview
The RFSSMAA4JCCA is an SSMA Connector Jack with female socket configuration manufactured by Bulgin. This coaxial RF connector is designed for panel mount applications with flange mounting and four-hole fastening. The connector operates at 50 Ohms impedance with a maximum frequency rating of 40 GHz, making it suitable for high-frequency RF applications. The product is currently active and in stock with 1026 units available. Substitute parts are identified to provide alternative mounting configurations while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation
The RFSSMAA4JCCA and RFSSMAA2JEGA are functionally equivalent SSMA coaxial connectors that share identical electrical specifications and core mechanical characteristics. Both connectors maintain the same impedance (50 Ohms), frequency rating (40 GHz), connector type (Jack, Female Socket), contact termination method (Compression), and operating temperature range (-65°C ~ 165°C).
The primary difference between these parts is the mounting hole configuration: the RFSSMAA4JCCA features four-hole flange mounting, while the RFSSMAA2JEGA features two-hole flange mounting. This distinction affects only the panel mounting interface and does not impact electrical performance or RF characteristics.
Substitution is valid when the application permits the alternative mounting hole pattern. Both parts are manufactured by Bulgin, maintain ROHS3 compliance, and are classified under the same base product number (RFSSMA).

Engineering Selection Recommendations
Both RFSSMAA4JCCA and RFSSMAA2JEGA are active products with ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for production applications. Selection between these parts is determined by panel mounting hole requirements.
The RFSSMAA4JCCA is specified for applications requiring four-hole flange mounting. The RFSSMAA2JEGA is specified for applications requiring two-hole flange mounting. The voltage rating difference (335 V versus 350 V) is not a limiting factor for typical RF applications and does not restrict substitution eligibility.
Both connectors maintain identical RF performance characteristics, mechanical durability (500 mating cycles), and environmental operating specifications. Component selection should be based on the specific panel hole pattern available in the target application.
Frequently Asked Questions (FAQ)
Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA4JCCA?
A: Electrical and RF substitution is valid. The RFSSMAA2JEGA maintains identical impedance, frequency rating, operating temperature, and contact termination specifications. Substitution is contingent on the application panel accommodating two-hole mounting instead of four-hole mounting.
Q: What is the primary difference between these two connector models?
A: The primary difference is the flange mounting hole configuration. RFSSMAA4JCCA features four mounting holes, while RFSSMAA2JEGA features two mounting holes. All electrical and RF characteristics are identical.
Q: Are both parts RoHS compliant?
A: Yes, both RFSSMAA4JCCA and RFSSMAA2JEGA are ROHS3 compliant.
Q: Do these connectors have different voltage ratings?
A: The RFSSMAA4JCCA is rated at 335 V, while the RFSSMAA2JEGA is rated at 350 V. Both ratings are suitable for standard RF applications and do not restrict substitution.
Q: What is the maximum operating frequency for both connectors?
A: Both connectors operate at a maximum frequency of 40 GHz with 50 Ohms impedance.
Q: Are the mating cycle specifications identical?
A: Yes, both connectors are rated for 500 mating cycles.
Q: What materials are used in the connector construction?
A: Both connectors feature beryllium copper center contacts, stainless steel bodies, and polytetrafluoroethylene (PTFE) dielectric material.
