Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2JDFFFGE are identified based on strict equivalence of 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
• Operating Temperature Range: -65°C ~ 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)

Compliance Parameters (Must Match):

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

The RFSMAA2JDFFFGE features a 2-hole flange mounting configuration. Substitute RFSMAA2JEGACDD maintains identical specifications including the 2-hole flange design. The RFSMAA4JCCACDD variant differs only in mounting hole count (4-hole flange) while maintaining all electrical and material specifications, making it suitable for applications where panel hole patterns accommodate the 4-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

RFSMAA2JEGACDD is a direct parametric equivalent to RFSMAA2JDFFFGE. Both parts maintain identical electrical specifications, material composition, and mounting configuration with 2-hole flange design. Both are Active product status with ROHS3 Compliance and unlimited moisture sensitivity rating. Selection between these two parts is based on inventory availability and supply chain considerations, as they are functionally interchangeable.

RFSMAA4JCCACDD is a parametric equivalent with a single mechanical variation: the 4-hole flange mounting configuration replaces the 2-hole design. All electrical parameters, material specifications, operating ranges, and compliance certifications remain identical. This part is suitable for applications where the panel mounting interface requires four fastening points instead of two. The 4-hole configuration does not affect RF performance, impedance, frequency response, or thermal operating range.

All three parts maintain Active product status, ROHS3 Compliance, and EAR99 export classification. Selection should be based on panel hole pattern requirements and inventory status.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2JEGACDD be used as a direct replacement for RFSMAA2JDFFFGE?

A: Yes. RFSMAA2JEGACDD is a parametric equivalent with identical electrical specifications, material composition, impedance, frequency response, operating temperature range, voltage rating, and 2-hole flange mounting configuration. Both parts are Active status and ROHS3 Compliant.

Q: What is the difference between RFSMAA2JDFFFGE and RFSMAA4JCCACDD?

A: The primary difference is the mounting hole count. RFSMAA2JDFFFGE features a 2-hole flange, while RFSMAA4JCCACDD features a 4-hole flange. All electrical parameters, impedance, frequency response, operating temperature, voltage rating, and material specifications are identical. Selection depends on panel mounting hole pattern requirements.

Q: Are all three parts suitable for 50 Ohm RF applications up to 26.5 GHz?

A: Yes. All three parts (RFSMAA2JDFFFGE, RFSMAA2JEGACDD, and RFSMAA4JCCACDD) are rated for 50 Ohm impedance and support frequencies up to 26.5 GHz. They are electrically equivalent for RF performance.

Q: Do these connectors require special handling or storage?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Can the 4-hole variant RFSMAA4JCCACDD be used in applications designed for the 2-hole variant?

A: The 4-hole variant can be used only if the panel mounting interface accommodates four fastening points. The electrical and RF performance characteristics are identical, but mechanical compatibility with the panel hole pattern must be verified.

Q: Are these parts compliant with environmental regulations?

A: Yes. All three parts are ROHS3 Compliant and classified as EAR99 for export purposes. RFSMAA2JEGACDD and RFSMAA4JCCACDD are additionally noted as REACH Unaffected.

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

A: All three parts operate across -65°C to 165°C, supporting applications in both extreme cold and high-temperature environments.
