RFSSMAA4JCCB Equivalent & Substitute Parts

Part Overview

The RFSSMAA4JCCB is an SSMA Connector Jack with female socket configuration, manufactured by Bulgin for RF coaxial applications. This panel mount connector features compression contact termination and screw shield termination, rated for 50 Ohms impedance and operation up to 40 GHz. The part is actively produced and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, enabling direct replacement in applications where mounting hole configuration permits.

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA4JCCB are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Body Material: Stainless Steel
• Housing Color: Silver

Compliance Equivalence Criteria:

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction between substitute parts lies in the number of mounting holes (4-hole versus 2-hole flange configuration) and minor voltage rating variations. These differences do not affect electrical performance or RF characteristics but determine physical panel integration requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSSMAA4JCCB, RFSSMAA4JCCA, and RFSSMAA2JEGA—maintain active product status and ROHS3 compliance. Selection between these coaxial connectors is determined by panel mounting hole configuration requirements:

RFSSMAA4JCCB and RFSSMAA4JCCA are functionally equivalent 4-hole flange mount connectors. Both support identical electrical specifications and operating parameters. Selection between these two 4-hole variants depends on application-specific voltage margin requirements, with RFSSMAA4JCCA and RFSSMAA4JCCB both rated at 335 V.

RFSSMAA2JEGA provides equivalent electrical and RF performance with a 2-hole flange mount configuration. This variant accommodates panel designs with 2-hole mounting patterns and offers a marginally higher voltage rating of 350 V. All three parts share identical impedance, frequency response, temperature range, and contact materials.

Selection should be based on panel mounting hole count and physical space constraints. All parts are suitable for direct substitution where mounting hole configuration permits.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA replace RFSSMAA4JCCB in an existing application?

A: Electrical and RF substitution is valid. Physical substitution requires that the panel mounting pattern accommodates a 2-hole flange configuration instead of 4-hole. Verify panel hole spacing and count before implementation.

Q: What is the primary difference between RFSSMAA4JCCB and RFSSMAA4JCCA?

A: Both are 4-hole flange mount SSMA connectors with identical electrical specifications. The parts are functionally equivalent for RF applications. Voltage rating is 335 V for both variants.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSSMAA4JCCB, RFSSMAA4JCCA, and RFSSMAA2JEGA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the maximum operating frequency for these connectors?

A: All three parts support operation up to 40 GHz with 50 Ohms impedance.

Q: Do these connectors support the same temperature range?

A: Yes. All three parts operate across -65°C to 165°C.

Q: What is the mating cycle rating for these connectors?

A: All three parts are rated for 500 mating cycles.

Q: Can I use RFSSMAA4JCCA as a direct replacement for RFSSMAA4JCCB?

A: Yes. Both parts share identical mounting hole configuration (4-hole), electrical specifications, and RF characteristics. Direct substitution is valid.

Q: What materials are used in the center contact and dielectric?

A: Center contacts are Beryllium Copper. Dielectric material is Polytetrafluoroethylene (PTFE) for all three variants.
