RFSSMAA4JAAA Equivalent & Substitute Parts

Part Overview

The RFSSMAA4JAAA is an SSMA Connector Jack with female socket configuration manufactured by Bulgin, designed for 50 Ohm RF coaxial applications. This panel mount connector features a flange with four-hole mounting and compression contact termination. The part is Active in product status and ROHS3 compliant, supporting frequencies up to 40 GHz with an operating temperature range of -65°C to 165°C. Substitute parts are identified when mechanical mounting configurations or voltage specifications differ while maintaining electrical compatibility across core RF parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA4JAAA are identified based on electrical and mechanical compatibility within the SSMA connector family. The substitution logic is determined by the following core parameters:

Electrical Compatibility Parameters:

• Connector Style: SSMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 40 GHz
• Contact Termination: Compression
• Shield Termination: Screw
• Center Contact Material: Beryllium Copper
• Dielectric Material: PTFE
• Operating Temperature: -65°C ~ 165°C
• Mating Cycles: 500

Mechanical Variation Parameters:

• Mounting Feature: Flange (4-hole vs. 2-hole configurations)
• Voltage Rating: 335 V or 350 V

Substitute parts maintain identical electrical performance and RF characteristics while differing in panel mounting hole count or voltage specification. All substitute parts share the same base product number (RFSSMA) and are manufactured by Bulgin with Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

RFSSMAA4JCCA is electrically and mechanically equivalent to RFSSMAA4JAAA. Both parts feature identical 4-hole flange mounting configurations and 335 V voltage ratings. Selection between these two parts is based on inventory availability and procurement lead times. Both parts maintain Active product status and ROHS3 compliance.

RFSSMAA2JEGA is electrically equivalent to RFSSMAA4JAAA with a mechanical variation in mounting configuration. This part features a 2-hole flange instead of 4-hole flange and provides a higher voltage rating of 350 V. Selection of RFSSMAA2JEGA is appropriate when panel layout requires 2-hole mounting geometry or when the higher voltage specification is required for the application. This part maintains Active product status and ROHS3 compliance.

All three parts are suitable for RF applications requiring 50 Ohm impedance, compression contact termination, and operation up to 40 GHz. Selection among these parts is determined by mechanical mounting requirements and voltage specification compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA4JAAA?

A: RFSSMAA2JEGA is electrically compatible with RFSSMAA4JAAA across all RF parameters. However, the mechanical mounting configuration differs: RFSSMAA2JEGA features 2-hole flange mounting while RFSSMAA4JAAA features 4-hole flange mounting. Substitution is valid only when the panel layout accommodates 2-hole mounting geometry.

Q: What is the difference between RFSSMAA4JAAA and RFSSMAA4JCCA?

A: Both parts are identical in electrical performance, impedance, frequency range, and mounting configuration (4-hole flange). Both maintain 335 V voltage rating and 50 Ohm impedance. These parts are interchangeable from an engineering standpoint.

Q: Does the voltage rating difference between RFSSMAA4JAAA (335 V) and RFSSMAA2JEGA (350 V) affect RF performance?

A: The voltage rating difference does not affect RF performance characteristics. Both parts maintain identical impedance, frequency response, and contact termination specifications. The voltage rating difference reflects the dielectric withstand capability and is application-dependent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RFSSMAA4JAAA, RFSSMAA4JCCA, and RFSSMAA2JEGA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What determines whether a part can substitute for RFSSMAA4JAAA?

A: Substitution is determined by matching core electrical parameters: SSMA connector style, Jack female socket type, 50 Ohm impedance, compression contact termination, screw shield termination, 40 GHz maximum frequency, -65°C to 165°C operating temperature, and 500 mating cycles. Mechanical variations in flange hole count and voltage rating do not prevent substitution when the application accommodates these differences.
