RFSMAA4PAAA SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA4PAAA is an SMA connector plug manufactured by Bulgin, designed for 50 Ohm RF coaxial applications requiring panel mount installation. This male pin connector features compression contact termination and screw shield termination, rated for frequencies up to 26.5 GHz. The connector is constructed with beryllium copper center contacts and stainless steel body, operating across a temperature range of -65°C to 165°C. The part is ROHS3 compliant and maintains active product status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, enabling component interchangeability in system designs where specific mounting hole configurations are not critical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4PAAA are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Compression
• Shield Termination: Screw
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Frequency - Max: 26.5 GHz
• Operating Temperature: -65°C ~ 165°C
• Voltage Rating: 335 V
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polyetherimide (PEI)
• RoHS Status: ROHS3 Compliant
• Mating Cycles: 500
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts maintain all electrical performance characteristics and material specifications. Variations in mounting hole configuration (4-hole versus 2-hole flange design) represent mechanical design differences that do not affect RF performance or electrical compatibility, provided the panel mounting interface accommodates the specific flange geometry.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA4PAAA, RFSMAA2PEGA, and RFSMAA4PCCA—are active Bulgin products with ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by panel mounting hole configuration requirements:

RFSMAA4PAAA and RFSMAA4PCCA both feature 4-hole flange mounting configurations and are electrically and mechanically equivalent. Both maintain 905 and 1057 units in stock respectively.

RFSMAA2PEGA features a 2-hole flange mounting configuration while maintaining all electrical performance parameters. This variant is selected when panel designs specify 2-hole mounting geometry.

All three parts support identical RF performance to 26.5 GHz, operate across -65°C to 165°C, and maintain 50 Ohm impedance with compression contact termination. Component selection is based on mechanical panel interface compatibility rather than electrical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PEGA be used as a direct replacement for RFSMAA4PAAA?

A: RFSMAA2PEGA is electrically equivalent to RFSMAA4PAAA across all RF and electrical parameters. However, the 2-hole flange configuration differs from the 4-hole design. Substitution is valid only when the panel mounting interface accommodates the 2-hole flange geometry.

Q: What is the primary difference between RFSMAA4PAAA and RFSMAA4PCCA?

A: Both parts share identical electrical specifications, impedance, frequency rating, temperature range, and material composition. The distinction lies in manufacturing or design revision designation. Both are suitable for equivalent applications with 4-hole flange mounting.

Q: Are all three parts rated for the same frequency range?

A: Yes. RFSMAA4PAAA, RFSMAA2PEGA, and RFSMAA4PCCA are all rated to 26.5 GHz maximum frequency with 50 Ohm impedance.

Q: Do these connectors support the same operating temperature range?

A: Yes. All three parts operate across -65°C to 165°C, with identical voltage rating of 335 V and mating cycle specification of 500 cycles.

Q: What material composition is used for the center contact?

A: All three parts use beryllium copper for center contacts with stainless steel body construction and polyetherimide dielectric material.

Q: Are all parts ROHS3 compliant?

A: Yes. RFSMAA4PAAA, RFSMAA2PEGA, and RFSMAA4PCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the primary selection criterion between these three parts?

A: Panel mounting hole configuration is the primary selection criterion. Choose 4-hole variants (RFSMAA4PAAA or RFSMAA4PCCA) for panels designed with 4-hole flange mounting. Choose the 2-hole variant (RFSMAA2PEGA) for panels designed with 2-hole flange mounting. Electrical performance is identical across all three options.
