Key Parameters

Substitute Part Grouping Explanation

The RFSMAA2PEGA and RFSMAA4PCCA are classified as parametric equivalents within the SMA coaxial connector category. Substitution between these parts is valid based on the following matching electrical and mechanical parameters:

Matching Parameters:

• 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
• Moisture Sensitivity Level: 1 (Unlimited)

Distinguishing Parameter:

• Mounting Feature Detail: RFSMAA2PEGA features 2-hole flange mounting; RFSMAA4PCCA features 4-hole flange mounting

The primary distinction between these parts is the number of mounting holes in the flange, which affects panel installation configuration. Both parts maintain identical electrical performance and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RFSMAA2PEGA and RFSMAA4PCCA are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by panel mounting hole configuration requirements:

RFSMAA2PEGA Selection Criteria:

• Applications requiring 2-hole flange mounting configuration
• Panel designs with 2-hole mounting pattern spacing
• Current inventory: 741 units available

RFSMAA4PCCA Selection Criteria:

• Applications requiring 4-hole flange mounting configuration
• Panel designs with 4-hole mounting pattern spacing
• Current inventory: 1057 units available

Both connectors deliver identical electrical performance across the specified frequency range (26.5 GHz maximum), temperature operating range (-65°C to 165°C), and voltage rating (335 V). The choice between these parts is purely mechanical, based on the panel mounting hole pattern of the target application.
