RFSMAA2PCED SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2PCED 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 equivalent electrical and mechanical parameters are required for applications where the original part number is unavailable or when alternative mounting configurations are necessary.

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2PCED are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is structured as follows:

Primary Substitution Criteria:

• Connector style, type, and gender must be identical (SMA, Plug, Male Pin)
• Impedance specification must match exactly (50 Ohms)
• Contact and shield termination methods must be equivalent (Compression contact, Screw shield)
• Operating temperature range must be identical (-65°C ~ 165°C)
• Voltage rating must be identical (335 V)
• Frequency maximum must be identical (26.5 GHz)
• Material composition must be identical (Beryllium Copper center contact, Stainless Steel body, Polyetherimide dielectric)
• Mating cycle rating must be identical (500 cycles)
• Compliance certifications must be equivalent (ROHS3 Compliant)

Secondary Variation Allowed:

• Mounting configuration (flange hole count) may vary between 2-hole and 4-hole configurations while maintaining panel mount flange type
• Inventory availability and packaging quantity do not affect substitution eligibility

The RFSMAA2PCED is directly substitutable with RFSMAA2PEGA (identical 2-hole flange configuration) and RFSMAA4PCCA (4-hole flange configuration variant).

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (RFSMAA2PCED, RFSMAA2PEGA, and RFSMAA4PCCA) maintain Active product status and full ROHS3 compliance, confirming their suitability for current design implementations. Selection between these equivalents is determined by panel mounting hole configuration requirements:

RFSMAA2PCED and RFSMAA2PEGA are direct equivalents with identical 2-hole flange mounting configuration. These parts are interchangeable for applications where the panel cutout and fastening holes are designed for 2-hole flange mounting.

RFSMAA4PCCA provides equivalent electrical and thermal performance with a 4-hole flange mounting configuration. This variant is selected when panel design incorporates 4-hole flange mounting specifications.

All three connectors deliver identical RF performance characteristics, operating temperature range, voltage handling, and mechanical durability across 500 mating cycles. The choice between 2-hole and 4-hole configurations is purely a mechanical interface decision based on panel design requirements.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PCED be replaced with RFSMAA2PEGA in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical 2-hole flange mounting. They share the same SMA connector style, 50 Ohm impedance, compression contact termination, and operating specifications. Direct substitution is valid for applications currently using RFSMAA2PCED.

Q: What is the difference between RFSMAA2PCED and RFSMAA4PCCA?

A: The primary difference is the flange mounting configuration. RFSMAA2PCED uses 2-hole flange mounting, while RFSMAA4PCCA uses 4-hole flange mounting. All electrical parameters, impedance, frequency response, temperature range, and material composition are identical. Selection depends on panel hole pattern design.

Q: Are these connectors suitable for high-frequency RF applications?

A: Yes. All three part numbers support frequencies up to 26.5 GHz with 50 Ohm impedance, making them suitable for microwave and high-frequency RF applications. The Beryllium Copper center contact and Polyetherimide dielectric ensure consistent performance across the specified frequency range.

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

A: All three connectors operate across -65°C to 165°C, providing performance in both cryogenic and elevated temperature environments. This range is identical across RFSMAA2PCED, RFSMAA2PEGA, and RFSMAA4PCCA.

Q: Are these connectors RoHS compliant?

A: Yes. All three part numbers are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: How many mating cycles are these connectors rated for?

A: All three connectors are rated for 500 mating cycles, providing consistent mechanical durability across repeated connection and disconnection operations.

Q: What materials are used in the connector construction?

A: The center contact is Beryllium Copper, the body is Stainless Steel, and the dielectric material is Polyetherimide (PEI). These materials are identical across all three part numbers and provide corrosion resistance and electrical performance stability.

Q: Can I use a 4-hole flange connector in a 2-hole mounting application?

A: No. The flange mounting configuration is a mechanical interface specification. A 4-hole connector requires a panel cutout and fastening holes designed for 4-hole mounting. Using RFSMAA4PCCA in a 2-hole panel design is not mechanically compatible.
