RFSSMAA2JCEE Equivalent & Substitute Parts

Part Overview

The RFSSMAA2JCEE is an SSMA Connector Jack with female socket configuration manufactured by Bulgin. This coaxial RF connector is designed for 50 Ohm panel mount applications with compression contact termination and screw shield termination. The connector operates across a frequency range up to 40 GHz and is rated for 350 V with an operating temperature range of -65°C to 165°C. The part is currently active in production status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, allowing for interchangeability in circuit designs and system implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA2JCEE are identified based on electrical and mechanical parameter equivalence within the SSMA connector family. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Connector style (SSMA)
• Connector type (Jack, Female Socket)
• Impedance (50 Ohms)
• Frequency maximum rating (40 GHz)
• Voltage rating (350 V or higher)
• Operating temperature range (-65°C ~ 165°C)

Mechanical Parameters:

• Mounting type (Panel Mount)
• Mounting feature (Flange)
• Contact termination (Compression)
• Shield termination (Screw)
• Center contact material (Beryllium Copper)
• Body material (Stainless Steel)
• Dielectric material (PTFE)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The RFSSMAA2JCEE has two identified substitutes: RFSSMAA2JEGA and RFSSMAA4JCCA. Both maintain all critical electrical and mechanical parameters. The primary distinction between these parts is the mounting hole configuration: RFSSMAA2JCEE and RFSSMAA2JEGA feature 2-hole flange mounting, while RFSSMAA4JCCA features 4-hole flange mounting. This difference affects panel integration but does not alter electrical performance or connector interface specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSSMAA2JCEE, RFSSMAA2JEGA, and RFSSMAA4JCCA—are active production components manufactured by Bulgin and maintain ROHS3 compliance with Moisture Sensitivity Level 1. These parts are electrically equivalent across all critical RF parameters including impedance, frequency response, and operating temperature range.

RFSSMAA2JCEE and RFSSMAA2JEGA are direct electrical and mechanical equivalents, differing only in internal design or manufacturing process. Both feature 2-hole flange mounting configurations suitable for standard panel integration.

RFSSMAA4JCCA provides an alternative with 4-hole flange mounting, offering enhanced mechanical stability for applications requiring additional fastening points. The voltage rating of RFSSMAA4JCCA is 335 V compared to 350 V for the other variants; this difference remains within acceptable operating margins for most RF applications operating below 335 V.

Selection between these parts should be based on panel mounting hole requirements and available inventory. All three parts maintain identical RF performance characteristics and environmental compliance specifications.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JCEE?

A: Yes. RFSSMAA2JEGA maintains identical electrical and mechanical specifications as RFSSMAA2JCEE, including connector style, impedance, frequency rating, operating temperature, and mounting configuration. Both feature 2-hole flange mounting.

Q: What is the primary difference between RFSSMAA4JCCA and the 2-hole variants?

A: RFSSMAA4JCCA features 4-hole flange mounting instead of 2-hole mounting. This provides additional mechanical fastening points for panel integration. All electrical RF parameters remain identical.

Q: Is the voltage rating difference between RFSSMAA4JCCA (335 V) and RFSSMAA2JCEE (350 V) significant?

A: The 15 V difference is a specification variance within the SSMA connector family. Selection should be based on application voltage requirements. For applications operating at or below 335 V, RFSSMAA4JCCA is suitable. For applications requiring the full 350 V rating, RFSSMAA2JCEE or RFSSMAA2JEGA should be selected.

Q: Are all three parts RoHS3 compliant?

A: Yes. RFSSMAA2JCEE, RFSSMAA2JEGA, and RFSSMAA4JCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What mounting hole configuration should I select for my application?

A: Select 2-hole mounting (RFSSMAA2JCEE or RFSSMAA2JEGA) for standard panel designs. Select 4-hole mounting (RFSSMAA4JCCA) for applications requiring enhanced mechanical stability or where panel design specifies four fastening points.

Q: Do these connectors support the same frequency range?

A: Yes. All three parts support operation up to 40 GHz with 50 Ohm impedance, making them suitable for identical RF applications.

Q: What is the operating temperature range for all variants?

A: All three parts operate across -65°C to 165°C, providing equivalent thermal performance across the substitute group.
