RFSMAA4PAAD Equivalent & Substitute Parts

Part Overview

The RFSMAA4PAAD is an SMA Connector Plug with male pin configuration manufactured by Bulgin, designed for 50 Ohms RF coaxial applications. This panel mount connector features compression contact termination, screw shield termination, and a four-hole flange mounting configuration. The connector is rated for frequencies up to 26.5 GHz and operates across a temperature range of -65°C to 165°C. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified to address specific mounting configuration requirements while maintaining electrical and mechanical compatibility within the SMA connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4PAAD are identified based on strict electrical and mechanical parameter equivalence within the SMA connector category. The substitution logic is based on the following criteria:

Electrical Equivalence Parameters:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Compression
• Shield Termination: Screw
• Frequency - Max: 26.5 GHz
• Operating Temperature: -65°C ~ 165°C
• Voltage Rating: 335 V
• Mating Cycles: 500

Mechanical Equivalence Parameters:

• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polyetherimide (PEI)

Compliance Parameters:

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

The identified substitute parts maintain full electrical and material compatibility. Differences exist only in the mounting hole configuration, which is a mechanical design parameter that does not affect electrical performance or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA4PAAD, RFSMAA2PEGA, and RFSMAA4PCCA—maintain Active product status and are ROHS3 compliant. Selection between these parts is determined by panel mounting hole requirements:

RFSMAA4PAAD is specified for applications requiring four-hole flange mounting configuration.

RFSMAA2PEGA is specified for applications requiring two-hole flange mounting configuration. This part provides electrical and thermal equivalence to RFSMAA4PAAD with a reduced mounting hole count.

RFSMAA4PCCA is specified for applications requiring four-hole flange mounting configuration and serves as a direct mechanical and electrical equivalent to RFSMAA4PAAD.

All parts share identical electrical performance characteristics, material composition, temperature ratings, and compliance certifications. The selection between RFSMAA4PAAD and RFSMAA4PCCA depends on panel design specifications and mechanical fastening requirements. The selection of RFSMAA2PEGA is appropriate only when panel design accommodates two-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PEGA be used as a substitute for RFSMAA4PAAD?

A: RFSMAA2PEGA is electrically and thermally equivalent to RFSMAA4PAAD. The difference is the mounting hole configuration: RFSMAA2PEGA features a two-hole flange while RFSMAA4PAAD features a four-hole flange. Substitution is possible only if the panel design accommodates two-hole mounting.

Q: What is the difference between RFSMAA4PAAD and RFSMAA4PCCA?

A: Both parts share identical electrical specifications, impedance, frequency rating, operating temperature range, and material composition. Both feature four-hole flange mounting. The parts are mechanically and electrically interchangeable.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSMAA4PAAD, RFSMAA2PEGA, and RFSMAA4PCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the maximum frequency rating for these SMA connectors?

A: All three parts are rated for frequencies up to 26.5 GHz.

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.

Q: What materials are used in the center contact and body?

A: The center contact is Beryllium Copper. The body is Stainless Steel. The dielectric material is Polyetherimide (PEI). These material specifications are identical across all three parts.

Q: What is the impedance rating for these connectors?
