RFSMAA2JDFDGCI SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JDFDGCI is an SMA connector jack manufactured by Bulgin, designed as a female socket for 50 Ohm RF applications. This panel mount, through-hole solder connector features a flanged design with two mounting holes and operates across a frequency range up to 26.5 GHz. The connector is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or specific mounting hole configurations necessitate alternative component selection while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JDFDGCI are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Primary Substitution Criteria:

• Connector Style: SMA (identical)
• Connector Type: Jack, Female Socket (identical)
• Impedance: 50 Ohms (identical)
• Mounting Type: Panel Mount, Through Hole (identical)
• Mounting Feature: Flange (identical)
• Contact Termination: Solder (identical)
• Shield Termination: Solder (identical)
• Frequency - Max: 26.5 GHz (identical)
• Operating Temperature Range: -65°C ~ 165°C (identical)
• Voltage Rating: 335 V (identical)
• Mating Cycles: 500 (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Mechanical Variation Allowed:

• Mounting hole configuration (2-hole vs. 4-hole flange design)

The RFSMAA2JDFDGCI features a 2-hole flange mounting configuration. Substitute part RFSMAA2JEGACDD maintains identical 2-hole configuration. Substitute part RFSMAA4JCCACDD features a 4-hole flange configuration, which represents a mechanical variation suitable for applications requiring additional mounting stability or different PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JDFDGCI, RFSMAA2JEGACDD, and RFSMAA4JCCACDD—are Active product status and ROHS3 compliant. Selection between these parts is determined by mounting hole configuration requirements:

RFSMAA2JDFDGCI and RFSMAA2JEGACDD are direct electrical and mechanical equivalents, both featuring 2-hole flange mounting. These parts are interchangeable for applications designed with 2-hole mounting hole patterns.

RFSMAA4JCCACDD provides identical electrical performance and operating characteristics but features a 4-hole flange mounting configuration. This variant is suitable for applications requiring four mounting points for enhanced mechanical stability or where PCB layout specifications mandate 4-hole mounting patterns.

All parts maintain compliance with ROHS3 regulations and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGACDD be used as a direct replacement for RFSMAA2JDFDGCI?

A: Yes. RFSMAA2JEGACDD is a parametric equivalent with identical electrical specifications, impedance, frequency range, operating temperature, voltage rating, and mounting configuration. Both feature 2-hole flange mounting and are electrically and mechanically interchangeable.

Q: What is the primary difference between RFSMAA2JDFDGCI and RFSMAA4JCCACDD?

A: The primary difference is the mounting hole configuration. RFSMAA2JDFDGCI features a 2-hole flange design, while RFSMAA4JCCACDD features a 4-hole flange design. All other electrical and mechanical parameters are identical. Selection depends on the PCB mounting hole pattern specification.

Q: Are all three parts suitable for the same frequency range?

A: Yes. All three parts—RFSMAA2JDFDGCI, RFSMAA2JEGACDD, and RFSMAA4JCCACDD—support operation up to 26.5 GHz and maintain 50 Ohm impedance across this frequency range.

Q: Do these connectors require special handling during assembly?

A: No. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: Can the 4-hole variant (RFSMAA4JCCACDD) be used in a 2-hole mounting application?

A: The 4-hole variant cannot be used in a 2-hole mounting application without PCB modification. The mounting hole pattern must match the connector flange design. Conversely, the 2-hole variants cannot be used in 4-hole mounting applications.

Q: Are all parts RoHS compliant?

A: Yes. All three parts—RFSMAA2JDFDGCI, RFSMAA2JEGACDD, and RFSMAA4JCCACDD—are ROHS3 compliant.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across the temperature range of -65°C to 165°C, suitable for industrial and high-temperature RF applications.
