RFSMAA2PCEA SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2PCEA is an SMA connector plug manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation with flange-mounted configuration and two-hole fastening. 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 full ROHS3 compliance. Substitute parts are identified when design requirements necessitate alternative mounting configurations, inventory constraints occur, or equivalent electrical and mechanical specifications are required for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2PCEA are identified based on strict equivalence of electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence Parameters:

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

Mechanical Equivalence Parameters:

• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Contact Termination: Compression
• Shield Termination: Screw
• Fastening Type: Threaded

Material and Compliance Parameters:

• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polyetherimide (PEI)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitutes maintain full electrical compatibility and material specifications. Differences exist only in the number of mounting holes (2-hole versus 4-hole configurations), which represents a mechanical variation within the same connector family while preserving all electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2PCEA, RFSMAA2PEGA, and RFSMAA4PCCA—are classified as Active product status and maintain identical electrical specifications, material composition, and regulatory compliance. Selection between these parts is determined by panel mounting hole requirements:

RFSMAA2PCEA and RFSMAA2PEGA are functionally equivalent with 2-hole flange mounting configurations. Both parts support identical RF performance up to 26.5 GHz, operate across the full temperature range of -65°C to 165°C, and comply with ROHS3 standards. These parts are suitable for applications requiring two-point mechanical fastening.

RFSMAA4PCCA provides a 4-hole flange mounting configuration while maintaining all electrical and material specifications identical to the 2-hole variants. This configuration accommodates panel designs requiring four-point mechanical fastening for enhanced structural stability or specific mounting hole patterns.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical voltage and frequency performance characteristics. Selection is based solely on mechanical mounting hole requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Are RFSMAA2PCEA and RFSMAA2PEGA electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 50 Ohm impedance, 26.5 GHz maximum frequency, 335 V voltage rating, and -65°C to 165°C operating temperature range. Both utilize compression contact termination and screw shield termination with identical material composition.

Q: What is the primary difference between the 2-hole and 4-hole mounting configurations?

A: The RFSMAA2PCEA and RFSMAA2PEGA feature 2-hole flange mounting, while the RFSMAA4PCCA features 4-hole flange mounting. All other electrical and mechanical specifications remain identical. Selection depends on the panel hole pattern and mechanical fastening requirements of the target application.

Q: Can RFSMAA4PCCA be used in place of RFSMAA2PCEA?

A: RFSMAA4PCCA is electrically equivalent to RFSMAA2PCEA and maintains identical RF performance. However, the 4-hole mounting configuration requires a panel with four mounting holes instead of two. Physical panel compatibility must be verified before substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSMAA2PCEA, RFSMAA2PEGA, and RFSMAA4PCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for applications requiring regulatory compliance.

Q: What is the mating cycle rating for these connectors?

A: All three parts are rated for 500 mating cycles, indicating the number of times the connector can be mated and unmated while maintaining electrical and mechanical specifications.

Q: Do these connectors require any special handling or storage conditions?

A: All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage practices apply.

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

A: The center contact is constructed from Beryllium Copper, and the body is constructed from Stainless Steel. The dielectric material is Polyetherimide (PEI). These materials are consistent across all three part numbers.
