RFSMAA4PAAB SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA4PAAB is an SMA connector plug manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation with flange-mounted configuration. This male pin connector utilizes compression contact termination and screw shield termination, operating across a frequency range up to 26.5 GHz. The connector is classified as Active product status and maintains ROHS3 compliance. Substitute parts are identified when design requirements necessitate alternative mounting hole configurations or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility within the same connector family.

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4PAAB are identified based on strict electrical and mechanical parameter alignment within the Bulgin SMA connector family. The substitution logic is governed by the following criteria:

Electrical Parameters (Must Match):

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

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

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

Variable Parameter (Allows Substitution):

  • Mounting Hole Configuration: The RFSMAA4PAAB features 4-hole flange mounting, while the RFSMAA2PEGA features 2-hole flange mounting. This difference permits substitution when panel design accommodates the alternative hole pattern.

All identified substitute parts maintain identical electrical performance, thermal characteristics, and compliance certifications. Substitution is valid only when the mounting hole configuration of the alternative part aligns with the panel design requirements.

Engineering Selection Recommendations

Selection between RFSMAA4PAAB, RFSMAA2PEGA, and RFSMAA4PCCA is determined by panel mounting hole configuration requirements. All three connectors maintain identical electrical specifications, thermal operating range, and compliance certifications.

RFSMAA4PAAB and RFSMAA4PCCA are directly interchangeable for applications requiring 4-hole flange mounting. Both parts deliver equivalent RF performance at frequencies up to 26.5 GHz with 50 Ohm impedance. Selection between these two 4-hole variants may be based on inventory availability or procurement lead time.

RFSMAA2PEGA provides equivalent electrical and thermal performance for applications where 2-hole flange mounting is specified. This variant maintains all compression contact and screw shield termination characteristics of the 4-hole configurations.

All substitute parts carry Active product status and ROHS3 compliance certification, confirming ongoing manufacturer support and regulatory alignment. Moisture Sensitivity Level 1 (Unlimited) classification indicates no special handling or storage requirements for any variant.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA4PAAB be replaced with RFSMAA2PEGA?

A: Substitution is valid when the panel design accommodates 2-hole flange mounting. Both connectors deliver identical electrical performance and thermal characteristics. The primary difference is the mounting hole pattern: RFSMAA4PAAB uses 4 holes while RFSMAA2PEGA uses 2 holes. Panel geometry must support the alternative hole configuration.

Q: What is the difference between RFSMAA4PAAB and RFSMAA4PCCA?

A: Both connectors feature 4-hole flange mounting and are electrically and mechanically equivalent. They maintain identical impedance (50 Ohms), frequency response (26.5 GHz maximum), operating temperature range (-65°C to 165°C), and compression contact termination. These parts are direct substitutes for one another.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSMAA4PAAB, RFSMAA2PEGA, and RFSMAA4PCCA all carry ROHS3 compliance certification. All three parts are suitable for applications requiring regulatory compliance with ROHS3 standards.

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

A: All three SMA connector variants operate across -65°C to 165°C. This temperature range applies to RFSMAA4PAAB, RFSMAA2PEGA, and RFSMAA4PCCA without variation.

Q: Do these connectors require special handling or storage?

A: No. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage and handling procedures apply.

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

A: All three connectors support operation up to 26.5 GHz. Frequency performance is identical across RFSMAA4PAAB, RFSMAA2PEGA, and RFSMAA4PCCA.

Q: Can these connectors be used interchangeably in RF applications?

A: Electrical interchangeability is confirmed for all three parts. Mechanical interchangeability depends on panel mounting hole configuration. Applications requiring 4-hole mounting accept RFSMAA4PAAB or RFSMAA4PCCA. Applications requiring 2-hole mounting accept RFSMAA2PEGA. RF performance characteristics remain constant across all variants.

Q: What materials are used in the connector construction?

A: All three connectors use stainless steel body material with beryllium copper center contacts and polyetherimide (PEI) dielectric material. Material composition is identical across RFSMAA4PAAB, RFSMAA2PEGA, and RFSMAA4PCCA.
