RFSMAA2JCCDQ SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The RFSMAA2JCCDQ is an SMA Connector Jack, Female Socket manufactured by Bulgin, designed for 50 Ohms RF coaxial applications. This panel mount, through-hole solder connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures from -65°C to 165°C. The part is Active in product status and ROHS3 Compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector series, enabling direct replacement in applications where mounting hole configuration or specific connector variants do not restrict interchangeability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JCCDQ are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 26.5 GHz
• Voltage Rating: 335 V
• Operating Temperature: -65°C ~ 165°C

Mechanical Parameters (Must Match):

• Mounting Type: Panel Mount, Through Hole
• Mounting Feature: Flange
• Contact Termination: Solder
• Shield Termination: Solder
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polyetherimide (PEI)
• Mating Cycles: 500

Compliance Parameters (Must Match):

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

Substitute parts may differ in the number of mounting holes (flange hole configuration) while maintaining all other parameters. This variation does not affect electrical performance but impacts physical board layout and mechanical mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JCCDQ, RFSMAA2JEGDQ, and RFSMAA4JCCDQ—are Active products manufactured by Bulgin and maintain ROHS3 Compliance with Moisture Sensitivity Level 1 (Unlimited). Selection between these parts is determined by mounting hole configuration requirements:

RFSMAA2JCCDQ and RFSMAA2JEGDQ are functionally equivalent SMA connectors with two-hole flange mounting configurations. Both support identical electrical performance across the 50 Ohm, 26.5 GHz operating range and identical mechanical specifications.

RFSMAA4JCCDQ provides a four-hole flange mounting configuration while maintaining all electrical and material specifications of the two-hole variants. This part is selected when PCB layout or mechanical assembly requirements specify four mounting holes for increased mechanical stability or compliance with specific mounting standards.

All three parts are suitable for direct substitution within their respective mounting hole categories, provided that the target application's PCB footprint and mechanical mounting design accommodate the flange hole configuration of the selected connector.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JCCDQ be replaced with RFSMAA4JCCDQ?

A: Both parts are electrically and mechanically equivalent SMA connectors with identical 50 Ohm impedance, 26.5 GHz frequency rating, and operating specifications. The primary difference is the flange mounting hole configuration: RFSMAA2JCCDQ has two mounting holes, while RFSMAA4JCCDQ has four mounting holes. Substitution is possible only if the target PCB footprint and mechanical assembly design support the four-hole configuration.

Q: What is the difference between RFSMAA2JCCDQ and RFSMAA2JEGDQ?

A: Both parts are two-hole flange-mounted SMA connectors with identical electrical and mechanical specifications. They are parametric equivalents and can be used interchangeably in applications where the two-hole mounting configuration is required.

Q: Are all three parts ROHS3 Compliant?

A: Yes. RFSMAA2JCCDQ, RFSMAA2JEGDQ, and RFSMAA4JCCDQ are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

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

A: All three SMA connectors operate at a maximum frequency of 26.5 GHz and maintain 50 Ohm impedance across this range.

Q: What is the operating temperature range?

A: All three parts operate across the temperature range of -65°C to 165°C.

Q: What materials are used in the connector construction?

A: All three parts feature Beryllium Copper center contacts, Stainless Steel body material, and Polyetherimide (PEI) dielectric material.

Q: How many mating cycles are rated for these connectors?

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

Q: What is the voltage rating?

A: All three parts have a voltage rating of 335 V.
