RFSMAA4PAAE SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA4PAAE 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 with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when design requirements necessitate alternative mounting hole configurations or when inventory constraints require equivalent electrical and mechanical performance from alternative part numbers within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4PAAE are determined by electrical and mechanical parameter equivalence within the Bulgin SMA connector family. The primary substitution criteria are:

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
• Operating Temperature: -65°C ~ 165°C
• Voltage Rating: 335 V
• Mating Cycles: 500

Mechanical Parameters (Must Match):

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

Allowable Variation:

• Mounting hole configuration (4-hole vs. 2-hole flange design)

The RFSMAA4PAAE features a 4-hole flange mounting configuration. Substitute part RFSMAA2PEGA provides equivalent electrical performance with a 2-hole flange configuration. Substitute part RFSMAA4PCCA maintains the 4-hole flange configuration with identical electrical specifications. All substitute parts maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

RFSMAA4PAAE Primary Selection: The RFSMAA4PAAE is the specified part number for applications requiring a 4-hole flange-mounted SMA connector plug with 50 Ohm impedance and compression contact termination. This part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, suitable for deployment in RF systems operating up to 26.5 GHz.

RFSMAA4PCCA Direct Equivalent: The RFSMAA4PCCA provides direct electrical and mechanical equivalence to the RFSMAA4PAAE, maintaining identical 4-hole flange configuration. This part is suitable for direct substitution when the primary part number is unavailable. Both parts share identical electrical specifications, operating parameters, and compliance certifications.

RFSMAA2PEGA Alternative Configuration: The RFSMAA2PEGA is electrically equivalent to the RFSMAA4PAAE but features a 2-hole flange mounting configuration instead of 4-hole. This part is suitable for applications where panel design accommodates 2-hole flange mounting. Selection of this alternative requires verification that the mechanical mounting interface supports 2-hole flange geometry.

All substitute parts maintain Active product status, ROHS3 compliance, and identical electrical performance specifications across the full operating temperature range and frequency bandwidth.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PEGA be used as a direct replacement for RFSMAA4PAAE?

A: RFSMAA2PEGA is electrically equivalent to RFSMAA4PAAE with identical RF performance, impedance, frequency response, and operating specifications. The primary difference is the mounting hole configuration: RFSMAA2PEGA features 2-hole flange mounting while RFSMAA4PAAE features 4-hole flange mounting. Substitution is possible only if the panel design accommodates 2-hole flange geometry.

Q: What is the difference between RFSMAA4PAAE and RFSMAA4PCCA?

A: Both RFSMAA4PAAE and RFSMAA4PCCA are 4-hole flange-mounted SMA connector plugs with identical electrical specifications, impedance, frequency range, and operating parameters. These parts are direct equivalents and interchangeable for applications requiring 4-hole flange mounting.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RFSMAA4PAAE, RFSMAA2PEGA, and RFSMAA4PCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for applications requiring environmental compliance certification.

Q: What mounting configurations are available?

A: The RFSMAA4PAAE and RFSMAA4PCCA provide 4-hole flange mounting. The RFSMAA2PEGA provides 2-hole flange mounting. All three parts are panel mount connectors with flange-based fastening using threaded fasteners.

Q: Do all substitute parts operate across the same temperature range?

A: Yes. RFSMAA4PAAE, RFSMAA2PEGA, and RFSMAA4PCCA all operate across the identical temperature range of -65°C to 165°C with 335 V voltage rating and 500 mating cycles.

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

A: All three parts (RFSMAA4PAAE, RFSMAA2PEGA, and RFSMAA4PCCA) support operation up to 26.5 GHz with 50 Ohm impedance, suitable for microwave and millimeter-wave RF applications.

Q: Are these parts suitable for compression cable termination?

A: Yes. All substitute parts utilize compression contact termination with screw shield termination, designed for direct cable connection without soldering.
