RFSSMAA2JCEA Equivalent & Substitute Parts

Part Overview

The RFSSMAA2JCEA is an SSMA Connector Jack with female socket configuration manufactured by Bulgin, designed for 50 Ohm RF applications requiring panel mount installation. This coaxial connector features compression contact termination and screw shield termination, rated for operation across -65°C to 165°C with a maximum frequency of 40 GHz. The part is currently active in production status and ROHS3 compliant. 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA2JCEA are identified based on strict equivalence of critical electrical and mechanical parameters. The substitution logic is organized into two categories:

Category 1: Direct Electrical Equivalents Parts that maintain identical electrical specifications including connector style (SSMA), connector type (Jack, Female Socket), impedance (50 Ohms), contact termination (Compression), shield termination (Screw), frequency rating (40 GHz), operating temperature range (-65°C ~ 165°C), voltage rating (350 V), and mating cycles (500). These parts differ only in mounting hole configuration but retain full functional compatibility.

Category 2: Mechanical Configuration Variants Parts that maintain all electrical parameters while providing alternative mounting hole patterns. The RFSSMAA4JCCA provides a 4-hole flange mount configuration compared to the 2-hole configuration of the RFSSMAA2JCEA, with a minor voltage rating variance (335 V versus 350 V).

All substitute parts share the following critical parameters with the main part:

• SSMA connector style
• Female socket jack configuration
• 50 Ohm impedance
• Compression contact termination
• Screw shield termination
• Panel mount with flange feature
• 40 GHz maximum frequency
• -65°C ~ 165°C operating temperature
• 500 mating cycles
• Beryllium copper center contact
• Stainless steel body
• PTFE dielectric material
• ROHS3 compliance
• MSL 1 rating

Engineering Selection Recommendations

RFSSMAA2JEGA Selection Criteria

The RFSSMAA2JEGA is a direct parametric equivalent to the RFSSMAA2JCEA, maintaining identical electrical specifications and 2-hole flange mount configuration. Both parts are ROHS3 compliant, carry MSL 1 rating, and share equivalent performance characteristics across all specified parameters. Selection of RFSSMAA2JEGA is appropriate when the RFSSMAA2JCEA is unavailable and identical mounting hole pattern is required. Current inventory availability for RFSSMAA2JEGA is 978 pieces.

RFSSMAA4JCCA Selection Criteria

The RFSSMAA4JCCA provides electrical equivalence to the RFSSMAA2JCEA with a 4-hole flange mount configuration in place of the 2-hole pattern. The voltage rating for RFSSMAA4JCCA is specified at 335 V compared to 350 V for the main part. All other electrical parameters, including impedance, frequency rating, operating temperature range, and mating cycles, remain equivalent. Selection of RFSSMAA4JCCA is appropriate when panel mounting design requires a 4-hole flange configuration and the reduced voltage rating is acceptable for the application. Current inventory availability for RFSSMAA4JCCA is 1026 pieces.

All substitute parts maintain active product status and full ROHS3 compliance, supporting equivalent regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JCEA?
