RFSMAA2JDFACDD SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JDFACDD 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 frequencies up to 26.5 GHz. The connector is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, enabling component interchangeability in applications where mounting hole configuration or specific flange geometry variations are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RFSMAA2JDFACDD is determined by strict equivalence across the following critical parameters: connector style (SMA), connector type (Jack, Female Socket), impedance (50 Ohms), mounting type (Panel Mount, Through Hole), contact and shield termination methods (Solder), maximum frequency (26.5 GHz), operating temperature range (-65°C ~ 165°C), voltage rating (335 V), mating cycles (500), and regulatory compliance (ROHS3).

The identified substitute parts maintain all electrical and thermal specifications. Variations in mounting hole configuration (2-hole versus 4-hole flange design) represent mechanical differences that do not affect RF performance or electrical compatibility. Both substitute parts are manufactured by Bulgin, carry Active product status, and meet identical compliance requirements. Selection between the main part and substitutes depends solely on panel layout requirements and available mounting hole spacing.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JDFACDD, RFSMAA2JEGACDD, and RFSMAA4JCCACDD—are Active status products manufactured by Bulgin with identical ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on mechanical mounting requirements rather than electrical performance.

RFSMAA2JDFACDD and RFSMAA2JEGACDD are functionally equivalent with 2-hole flange mounting configurations. Both support identical RF specifications and environmental operating conditions.

RFSMAA4JCCACDD provides a 4-hole flange mounting option while maintaining all electrical and thermal specifications. This variant accommodates panel designs requiring four mounting points for enhanced mechanical stability or specific PCB layout constraints.

Component selection should be determined by available panel mounting hole spacing and mechanical fastening requirements. All three parts deliver equivalent RF performance across the 26.5 GHz frequency range and identical reliability metrics.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JDFACDD be directly replaced with RFSMAA2JEGACDD?

A: Yes. Both parts are 2-hole flange SMA female jack connectors with identical electrical specifications, impedance, frequency range, and operating temperature. They are parametric equivalents.

Q: What is the primary difference between RFSMAA2JDFACDD and RFSMAA4JCCACDD?

A: The primary difference is the mounting hole configuration. RFSMAA2JDFACDD features a 2-hole flange, while RFSMAA4JCCACDD features a 4-hole flange. All RF electrical parameters remain identical.

Q: Are these connectors suitable for high-frequency applications?

A: Yes. All three parts support frequencies up to 26.5 GHz with 50 Ohm impedance, making them suitable for microwave and RF applications within this frequency range.

Q: Do all three parts meet the same compliance standards?

A: Yes. RFSMAA2JDFACDD, RFSMAA2JEGACDD, and RFSMAA4JCCACDD are all ROHS3 compliant with identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4010).

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

A: All three parts operate across -65°C to 165°C, providing performance across extended industrial and aerospace temperature ranges.

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

A: All three parts are rated for 500 mating cycles, defining the expected mechanical durability for repeated connection and disconnection operations.

Q: Can these connectors be used interchangeably in the same application?

A: Interchangeability depends on panel mounting hole availability. If the panel accommodates the specific flange hole configuration (2-hole or 4-hole), the parts are electrically and mechanically interchangeable.
