RFSMAA2JCCACDD SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JCCACDD is an SMA connector jack (female socket) manufactured by Bulgin, designed for 50 Ohm RF applications with panel mount, through-hole solder termination. This connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures from -65°C to 165°C. The part is currently active in production with 991 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family. Alternative models may be required due to inventory availability, specific mounting hole configurations, or procurement lead times while maintaining full functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JCCACDD are qualified based on strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

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

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)

Reliability Parameters (Must Match):

• Mating Cycles: 500
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitutes differ only in mounting hole configuration (2-hole versus 4-hole flange design), which represents a mechanical variation that does not affect electrical performance or functional compatibility in applications where the mounting hole pattern accommodates the alternative design.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2JCCACDD, RFSMAA2JEGACDD, and RFSMAA4JCCACDD—are active production components manufactured by Bulgin with ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by mounting hole configuration requirements:

RFSMAA2JCCACDD and RFSMAA2JEGACDD feature 2-hole flange mounting and are electrically and mechanically equivalent. Both are suitable for applications requiring two-point panel mounting.

RFSMAA4JCCACDD features 4-hole flange mounting and is suitable for applications requiring four-point panel mounting. This part maintains all electrical parameters and operating characteristics identical to the 2-hole variants.

Component selection should be based on the specific mounting hole pattern required by the application's panel design. All three parts maintain equivalent RF performance, impedance characteristics, and environmental operating specifications.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JCCACDD be directly replaced with RFSMAA2JEGACDD?

A: Yes. Both parts are electrically and mechanically equivalent SMA jack connectors with 2-hole flange mounting. They share identical impedance (50 Ohms), frequency response (26.5 GHz maximum), operating temperature range (-65°C to 165°C), and all material specifications. Substitution is valid when the application accommodates 2-hole flange mounting.

Q: What is the difference between RFSMAA2JCCACDD and RFSMAA4JCCACDD?

A: The primary difference is the mounting hole configuration. RFSMAA2JCCACDD features a 2-hole flange, while RFSMAA4JCCACDD features a 4-hole flange. All electrical parameters, impedance, frequency response, and operating characteristics are identical. Selection depends on the panel mounting hole pattern required by the application.

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

A: Yes. All three parts are rated for frequencies up to 26.5 GHz and maintain 50 Ohm impedance across this range. They are suitable for RF and microwave applications within this frequency specification.

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, making them suitable for both industrial and military applications requiring extended temperature performance.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: RFSMAA2JCCACDD and RFSMAA2JEGACDD can be used interchangeably in applications with 2-hole flange mounting. RFSMAA4JCCACDD can be substituted only in applications where 4-hole flange mounting is accommodated by the panel design. Electrical performance is equivalent across all three parts.
