RFSMAA2PCEC SMA Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RFSMAA2PCEC is an SMA connector plug manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation with flange mounting and compression termination. This coaxial connector operates across frequencies up to 26.5 GHz and is rated for operating temperatures between -65°C and 165°C. The part is currently active in production status with 902 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, enabling direct replacement in applications where mounting hole configuration or specific connector variants do not impose design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSMAA2PCEC are identified based on strict equivalence of electrical and mechanical parameters. The primary substitution criteria include:

Electrical Parameters (Must Match):

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

Mechanical Parameters (Must Match):

• Contact Termination: Compression
• Shield Termination: Screw
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polyetherimide (PEI)
• Mating Cycles: 500

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

The identified substitutes maintain all critical electrical and mechanical specifications. Variations in mounting hole configuration (2-hole versus 4-hole flange) represent the only physical difference between substitute parts and do not affect RF performance or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSMAA2PCEC, RFSMAA2PEGA, and RFSMAA4PCCA—are active production components manufactured by Bulgin with ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by panel mounting hole requirements:

RFSMAA2PCEC and RFSMAA2PEGA feature 2-hole flange mounting configurations and are electrically and mechanically equivalent. Both maintain 50 Ohm impedance, compression termination, and screw shield termination across the full 26.5 GHz frequency range.

RFSMAA4PCCA provides a 4-hole flange mounting configuration while maintaining all electrical parameters and material specifications of the 2-hole variants. This part is selected when panel design requires four mounting points for enhanced mechanical stability or when existing panel tooling specifies 4-hole flange geometry.

All three parts operate within the -65°C to 165°C temperature range, support 500 mating cycles, and carry unlimited moisture sensitivity classification. Component selection is based solely on mounting hole configuration requirements and panel design specifications.

Frequently Asked Questions (FAQ)

Q: Can RFSMAA2PCEC be directly replaced with RFSMAA2PEGA?

A: Yes. Both parts are electrically and mechanically equivalent with identical 50 Ohm impedance, compression termination, frequency response to 26.5 GHz, and operating temperature range. Both feature 2-hole flange mounting. Selection between these parts depends on inventory availability and supply chain considerations.

Q: What is the difference between RFSMAA2PCEC and RFSMAA4PCCA?

A: The primary difference is the mounting hole configuration. RFSMAA2PCEC features a 2-hole flange mount, while RFSMAA4PCCA features a 4-hole flange mount. All electrical parameters, impedance, frequency response, and material specifications are identical. Selection depends on panel design and mounting hole requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSMAA2PCEC, RFSMAA2PEGA, and RFSMAA4PCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can RFSMAA4PCCA be used in applications designed for 2-hole mounting?

A: No. RFSMAA4PCCA has a 4-hole flange configuration and cannot be mechanically installed in panels designed for 2-hole mounting. Panel tooling and hole spacing must match the connector flange specification.

Q: Do these connectors support the same frequency range?

A: Yes. All three parts—RFSMAA2PCEC, RFSMAA2PEGA, and RFSMAA4PCCA—support frequencies up to 26.5 GHz with 50 Ohm impedance.

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

A: All three parts operate across -65°C to 165°C, supporting both cryogenic and elevated temperature applications.

Q: Are the center contact materials identical across all three parts?

A: Yes. All three parts use Beryllium Copper center contacts with Stainless Steel bodies and Polyetherimide (PEI) dielectric material.
