RFSMAA4JCCACDD SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA4JCCACDD 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 four-hole flange mounting configuration and operates across frequencies up to 26.5 GHz. The connector is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when mechanical mounting configurations differ while maintaining identical electrical and RF performance characteristics, allowing for design flexibility in panel layout and PCB integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RFSMAA4JCCACDD is determined by equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Connector style: SMA
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 26.5 GHz
• Contact termination: Solder
• Shield termination: Solder
• Voltage rating: 335 V
• Operating temperature range: -65°C to 165°C
• Mating cycles: 500

Mechanical Compatibility Parameters:

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

Regulatory & Compliance Equivalence:

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

The RFSMAA2JEGACDD qualifies as a parametric equivalent substitute with one mechanical variation: the flange mounting configuration changes from four holes to two holes. All electrical, RF, thermal, and regulatory parameters remain identical.

Engineering Selection Recommendations

Both the RFSMAA4JCCACDD and RFSMAA2JEGACDD maintain Active product status with full manufacturing support and availability. Selection between these parts is determined solely by panel mounting hole pattern requirements:

RFSMAA4JCCACDD Selection Criteria:

• Applications requiring four-hole flange mounting configuration
• PCB layouts with four-hole mounting pattern spacing
• Designs prioritizing maximum mechanical stability through four-point fastening

RFSMAA2JEGACDD Selection Criteria:

• Applications requiring two-hole flange mounting configuration
• PCB layouts with two-hole mounting pattern spacing
• Designs with space constraints limiting fastening points

Both parts carry identical RoHS3 compliance certification and REACH unaffected status, ensuring regulatory equivalence for all markets and applications. Electrical performance, RF characteristics, thermal operating range, and reliability metrics are identical across both variants. The selection between these parts is a mechanical design decision with no impact on electrical functionality or compliance status.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGACDD be used as a direct replacement for RFSMAA4JCCACDD?

A: The RFSMAA2JEGACDD is electrically and RF equivalent to the RFSMAA4JCCACDD. The only difference is the flange mounting configuration: two holes versus four holes. Direct replacement is possible only if the PCB or panel layout accommodates the two-hole mounting pattern. If the design requires four-hole mounting, the RFSMAA4JCCACDD must be used.

Q: Are the RF performance characteristics identical between these two parts?

A: Yes. Both parts operate at 50 Ohms impedance, support frequencies to 26.5 GHz, and maintain identical electrical specifications including voltage rating, operating temperature range, and mating cycle ratings.

Q: What is the difference in mechanical mounting between these connectors?

A: The RFSMAA4JCCACDD features a four-hole flange mounting configuration, while the RFSMAA2JEGACDD features a two-hole flange mounting configuration. Both use threaded fastening and panel mount, through-hole solder termination. The mounting hole pattern is the only mechanical difference.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the RFSMAA4JCCACDD and RFSMAA2JEGACDD are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited) rating.

Q: Which part should be selected for new designs?

A: Selection depends on the mechanical mounting requirements of the application. If the PCB or panel design accommodates either mounting pattern, both parts are functionally equivalent. Verify the mounting hole spacing in your design documentation to determine which part is appropriate.

Q: Are there any performance differences in solder termination between these parts?

A: No. Both parts use identical solder termination for both contact and shield connections. Soldering procedures and thermal profiles are equivalent.

Q: What is the inventory status for these parts?

A: RFSMAA4JCCACDD has 1066 pieces in stock. RFSMAA2JEGACDD has 1172 pieces in stock. Both are available as new original components in bulk packaging.
