RFSMAA2JCCDGCI SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2JCCDGCI is an SMA connector jack (female socket) manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount through-hole solder termination. This coaxial connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures between -65°C and 165°C. The connector features a flanged mounting configuration with two mounting holes and extended insulation for enhanced electrical performance.

The part is currently in active production status with 948 units in stock. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical mounting compatibility, and material composition. Alternative part numbers are necessary when specific mounting hole configurations or inventory availability require component substitution while maintaining functional equivalence in RF circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JCCDGCI are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Connector style: SMA
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 26.5 GHz
• Operating temperature range: -65°C ~ 165°C
• Voltage rating: 335 V
• Contact and shield termination: Solder

Mechanical Parameters (Must Match):

• Mounting type: Panel Mount, Through Hole
• Mounting feature: Flange
• Fastening type: Threaded
• Center contact material: Beryllium Copper
• Body material: Stainless Steel
• Dielectric material: Polyetherimide (PEI)

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99

The RFSMAA2JCCDGCI features a 2-hole flange mounting configuration. Substitute part RFSMAA2JEGACDD maintains identical specifications including the 2-hole configuration. Substitute part RFSMAA4JCCACDD differs only in the mounting hole count (4-hole configuration) while maintaining all electrical and material specifications. The 4-hole variant provides alternative mechanical mounting options for panel integration where additional fastening points are required.

Parameter Comparison

Engineering Selection Recommendations

RFSMAA2JEGACDD is a direct parametric equivalent to RFSMAA2JCCDGCI. Both parts maintain identical electrical specifications, material composition, and 2-hole flange mounting configuration. Selection between these two parts is determined by inventory availability and supply chain considerations. Both parts are active production items with ROHS3 compliance and unlimited moisture sensitivity rating, suitable for immediate deployment in RF circuit applications.

RFSMAA4JCCACDD provides functional equivalence with a mechanical variation: the 4-hole flange mounting configuration. This part is selected when panel integration requires four mounting points for enhanced mechanical stability or when existing panel designs specify 4-hole flange mounting. All electrical parameters, operating ranges, and compliance certifications remain identical to the 2-hole variants. The 4-hole configuration does not affect RF performance, impedance matching, or frequency response characteristics.

Selection criteria are based on:

• Matching electrical specifications (50 Ohm impedance, 26.5 GHz maximum frequency, 335 V rating)
• Identical material composition and contact termination methods
• Active production status and ROHS3 compliance
• Mechanical mounting hole configuration requirements for panel integration

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGACDD be used as a direct replacement for RFSMAA2JCCDGCI?

A: Yes. RFSMAA2JEGACDD is a parametric equivalent with identical electrical specifications, material composition, operating temperature range, voltage rating, and 2-hole flange mounting configuration. Both parts are manufactured by Bulgin and maintain 50 Ohm impedance across the 26.5 GHz frequency range.

Q: What is the difference between the 2-hole and 4-hole mounting configurations?

A: The RFSMAA2JCCDGCI and RFSMAA2JEGACDD feature 2-hole flange mounting, while RFSMAA4JCCACDD features 4-hole flange mounting. The mounting hole count affects panel integration and mechanical fastening options. The 4-hole configuration provides additional mounting points for enhanced structural support. All electrical and RF performance characteristics remain identical across both configurations.

Q: Are all three parts RoHS compliant?

A: Yes. RFSMAA2JCCDGCI, RFSMAA2JEGACDD, and RFSMAA4JCCACDD are all ROHS3 compliant. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Can the 4-hole variant be used in applications designed for 2-hole connectors?

A: The 4-hole variant (RFSMAA4JCCACDD) can be used in applications designed for 2-hole connectors only if the panel layout accommodates the additional mounting holes. The electrical and RF performance characteristics are identical. Panel mechanical design must be evaluated to confirm compatibility with the 4-hole flange configuration.

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

A: All three parts (RFSMAA2JCCDGCI, RFSMAA2JEGACDD, and RFSMAA4JCCACDD) are rated for maximum frequency operation of 26.5 GHz, maintaining 50 Ohm impedance across this frequency range.

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

A: Yes. All three parts are rated for operating temperatures from -65°C to 165°C. The stainless steel body material and polyetherimide dielectric provide thermal stability across this temperature range.

Q: What termination method is used for these connectors?

A: Both the center contact and shield termination use solder attachment. These are through-hole solder connectors designed for PCB integration via wave soldering or selective soldering processes.
