RFSMAA4PCCB Equivalent & Substitute Parts

Part Overview

The RFSMAA4PCCB is an SMA Connector Plug with male pin configuration manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation with flange-mounted, four-hole fastening. This coaxial connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures between -65°C and 165°C. The connector utilizes compression contact termination with screw shield termination, making it suitable for high-frequency signal transmission in aerospace, telecommunications, and industrial RF systems.

The RFSMAA4PCCB maintains Active product status and is ROHS3 compliant. Substitute parts are identified based on electrical parameter equivalence and mechanical compatibility within the SMA connector family, allowing for component interchangeability in applications where specific mounting configurations may vary.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA4PCCB are identified based on strict electrical and mechanical parameter equivalence within the Bulgin SMA connector product line. The substitution logic is determined by the following critical parameters:

Electrical Equivalence Parameters:

• 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
• Mating Cycles: 500

Mechanical Compatibility Parameters:

• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Number of Ports: 1

The identified substitute parts maintain identical electrical performance characteristics and are compatible with the same RF signal transmission requirements. Mechanical differences are limited to the number of mounting holes, which represents a variation in panel attachment configuration rather than a functional incompatibility. Both substitute parts operate within the same frequency range, impedance specification, and environmental conditions as the primary part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA4PCCB, RFSMAA2PEGA, and RFSMAA4PCCA—are Active status products manufactured by Bulgin and maintain ROHS3 compliance. Selection between these parts is determined by panel mounting hole configuration requirements rather than electrical or environmental performance differences.

RFSMAA4PCCB and RFSMAA4PCCA are functionally identical with four-hole flange mounting configurations. Both parts support identical RF performance specifications, operating conditions, and mechanical interfaces. Selection between these two parts depends on component availability and supply chain considerations.

RFSMAA2PEGA provides equivalent electrical performance and environmental ratings with a two-hole flange mounting configuration. This part is suitable for applications where panel geometry or fastening requirements specify two-point attachment rather than four-point attachment.

All three parts maintain the same impedance (50 Ohms), frequency capability (26.5 GHz), contact termination method (compression), and operating temperature range (-65°C to 165°C). The Moisture Sensitivity Level of 1 (Unlimited) indicates no special storage or handling requirements for any of these parts.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PEGA be used as a direct replacement for RFSMAA4PCCB?

A: RFSMAA2PEGA is electrically and functionally equivalent to RFSMAA4PCCB. The primary difference is the mounting hole configuration: RFSMAA2PEGA uses two mounting holes while RFSMAA4PCCB uses four mounting holes. Substitution is possible if the panel design accommodates two-hole flange mounting. RF performance, impedance, frequency response, and environmental ratings are identical.

Q: What is the difference between RFSMAA4PCCB and RFSMAA4PCCA?

A: Both parts feature four-hole flange mounting and are electrically identical. They share the same impedance (50 Ohms), maximum frequency (26.5 GHz), contact termination method (compression), and operating temperature range (-65°C to 165°C). These parts are interchangeable from an electrical and mechanical standpoint.

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

A: Yes. RFSMAA4PCCB, RFSMAA2PEGA, and RFSMAA4PCCA all support frequencies up to 26.5 GHz with 50 Ohm impedance. Frequency performance is not a differentiating factor between these parts.

Q: What determines whether I should use a two-hole or four-hole mounting configuration?

A: The choice between two-hole (RFSMAA2PEGA) and four-hole (RFSMAA4PCCB or RFSMAA4PCCA) mounting is determined by panel design specifications and mechanical fastening requirements. Four-hole configurations provide increased mechanical stability and are preferred for high-vibration environments or applications requiring maximum panel retention force. Two-hole configurations are suitable for standard panel mount applications with adequate structural support.

Q: Do these parts require special handling or storage?

A: No. All three parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity concerns. Standard component storage practices are sufficient.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSMAA4PCCB, RFSMAA2PEGA, and RFSMAA4PCCA are all ROHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.

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

A: All three parts operate across the temperature range of -65°C to 165°C, providing performance in both cryogenic and elevated temperature applications.
