RFSMAA2JEGA SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The RFSMAA2JEGA is an SMA Connector Jack manufactured by Bulgin, classified as a Coaxial Connector (RF) for 50 Ohm impedance applications. This female socket panel mount connector features compression contact termination and screw shield termination, designed for RF signal transmission up to 26.5 GHz. The part is Active in product status with 755 units in current inventory stock.

Equivalent and substitute parts are identified when design requirements permit mechanical or electrical parameter variations while maintaining core functional compatibility within the SMA connector category. Substitution becomes necessary when primary part availability is limited, when alternative mounting configurations are required, or when sourcing from multiple manufacturers is strategically preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JEGA are identified based on strict electrical and mechanical parameter alignment within the SMA connector category. The substitution logic is based on the following core parameters that must remain constant:

Electrical Parameters (Non-Negotiable):

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 26.5 GHz
• Contact Termination: Compression
• Shield Termination: Screw
• Number of Ports: 1

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel

Environmental Parameters (Non-Negotiable):

• Operating Temperature: -65°C ~ 165°C
• Voltage Rating: 335 V
• Mating Cycles: 500

Compliance Parameters (Non-Negotiable):

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

Substitute parts may vary in the following parameters without affecting functional compatibility:

• Mounting hole configuration (2-hole vs. 4-hole flange)
• Center Contact Plating material
• Dielectric Material specification
• Manufacturer identity

Parameter Comparison

Engineering Selection Recommendations

RFSMAA2JEGA (Bulgin) - Primary Part

The RFSMAA2JEGA is the specified part with Active product status and full parameter documentation. This connector features a 2-hole flange mounting configuration and is ROHS3 compliant with MSL 1 rating. Selection of this part is appropriate when the 2-hole flange mounting pattern is required by the PCB or panel design.

RFSMAA4JCCA (Bulgin) - Parametric Equivalent

The RFSMAA4JCCA is a Bulgin-manufactured equivalent with identical electrical and environmental specifications to the RFSMAA2JEGA. The primary mechanical difference is the 4-hole flange mounting configuration. This part is ROHS3 compliant with MSL 1 rating and maintains all core electrical parameters. Selection of this part is appropriate when the 4-hole flange mounting pattern is required by the PCB or panel design, or when higher inventory availability (1150 units) is strategically preferred.

VC06FS001 and VC06FS002 (WITHWAVE CO LTD) - Cross-Manufacturer Equivalents

Both WITHWAVE parts (VC06FS001 and VC06FS002) are cross-manufacturer equivalents that maintain all core electrical, mechanical, and RF parameters. These parts feature gold-plated center contacts and are manufactured by WITHWAVE CO LTD. Operating temperature, voltage rating, and mating cycle specifications are not provided in available documentation for these parts. Selection of WITHWAVE parts is appropriate when cross-manufacturer sourcing is required or when gold-plated contact specifications are preferred. Both parts maintain Active product status with substantial inventory availability (841 and 1012 units respectively).

Frequently Asked Questions (FAQ)

Q: Can RFSMAA4JCCA be used as a direct replacement for RFSMAA2JEGA?

A: The RFSMAA4JCCA is electrically and environmentally equivalent to the RFSMAA2JEGA. The primary difference is the flange mounting hole configuration (4-hole vs. 2-hole). Direct substitution is possible only if the PCB or panel design accommodates the 4-hole flange pattern. Mechanical compatibility with the mounting surface must be verified before substitution.

Q: What is the difference between Bulgin and WITHWAVE substitute parts?

A: Both manufacturers provide SMA connectors with identical electrical specifications (50 Ohm impedance, 26.5 GHz maximum frequency, compression contact termination). The Bulgin parts (RFSMAA2JEGA and RFSMAA4JCCA) provide complete environmental specifications including operating temperature range (-65°C to 165°C), voltage rating (335 V), and mating cycle rating (500 cycles). The WITHWAVE parts (VC06FS001 and VC06FS002) feature gold-plated center contacts but do not provide operating temperature, voltage rating, or mating cycle specifications in available documentation.

Q: Are the WITHWAVE VC06FS001 and VC06FS002 parts interchangeable with each other?

A: Yes. Both WITHWAVE parts maintain identical electrical, mechanical, and RF specifications. The parts are functionally interchangeable. Selection between them may be based on inventory availability or specific procurement requirements.

Q: What does the flange mounting feature indicate?

A: The flange mounting feature indicates that the connector includes a mounting flange with threaded fastening holes for panel or PCB attachment. The RFSMAA2JEGA features a 2-hole flange, while the RFSMAA4JCCA features a 4-hole flange. The flange provides mechanical stability and RF shielding at the panel interface.

Q: Are all substitute parts ROHS3 compliant?

A: The Bulgin parts (RFSMAA2JEGA and RFSMAA4JCCA) are explicitly ROHS3 compliant with MSL 1 rating. RoHS compliance status is not specified in available documentation for the WITHWAVE parts (VC06FS001 and VC06FS002).

Q: What is the significance of the 50 Ohm impedance specification?

A: The 50 Ohm impedance is the standard characteristic impedance for RF coaxial connectors used in telecommunications, microwave, and RF applications. All substitute parts maintain this specification, ensuring signal integrity and impedance matching in RF transmission systems operating up to 26.5 GHz.

Q: Can these connectors be used in high-temperature applications?

A: The Bulgin parts (RFSMAA2JEGA and RFSMAA4JCCA) are rated for operating temperatures from -65°C to 165°C, suitable for industrial and aerospace applications. Operating temperature specifications are not provided for the WITHWAVE parts. Application requirements must be verified against available specifications before selection.

Q: What does compression contact termination mean?

A: Compression contact termination indicates that the cable is secured to the connector through a compression fitting mechanism rather than soldering. This method provides reliable mechanical and electrical connection while allowing for field assembly and disassembly without thermal stress to components.
