RFSSMAA2JCEC Equivalent & Substitute Parts

Part Overview

The RFSSMAA2JCEC 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 with 943 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, allowing for interchangeability in applications where specific mounting configurations or inventory availability require alternative part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA2JCEC are identified based on electrical and mechanical parameter equivalence within the SSMA connector family. The primary substitution criteria include:

Electrical Parameters (Must Match):

• Connector Style: SSMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 40 GHz
• Operating Temperature: -65°C ~ 165°C
• Mating Cycles: 500
• Center Contact Material: Beryllium Copper
• Dielectric Material: PTFE

Mechanical Parameters (Must Match):

• Mounting Type: Panel Mount
• Contact Termination: Compression
• Shield Termination: Screw
• Body Material: Stainless Steel
• Housing Color: Silver

Allowable Variations:

• Mounting Feature: Flange configuration (2-hole vs. 4-hole)
• Voltage Rating: Minor variations acceptable (350 V to 335 V)

The RFSSMAA2JCEC maintains a 2-hole flange mounting configuration. Substitute parts within this group preserve all core electrical and mechanical characteristics while accommodating different panel mounting hole patterns or minor voltage rating adjustments.

Parameter Comparison

Engineering Selection Recommendations

RFSSMAA2JEGA Selection Criteria: The RFSSMAA2JEGA is a direct parametric equivalent to the RFSSMAA2JCEC. Both parts maintain identical electrical specifications, mechanical configuration, and compliance certifications. The RFSSMAA2JEGA is suitable for applications requiring the same 2-hole flange mounting pattern. Selection between these two parts is based on inventory availability or procurement lead time, as no functional differences exist between them. Both parts are ROHS3 compliant and carry MSL 1 rating.

RFSSMAA4JCCA Selection Criteria: The RFSSMAA4JCCA is functionally equivalent to the RFSSMAA2JCEC with the primary distinction being a 4-hole flange mounting configuration instead of 2-hole. This part is suitable for applications where panel mounting requires four fastening points. The voltage rating is 335 V compared to 350 V in the RFSSMAA2JCEC; this 15 V reduction does not affect compatibility in standard 50 Ohm RF applications. All other electrical parameters, including frequency response, impedance, operating temperature, and mating cycle rating, remain identical. The RFSSMAA4JCCA is ROHS3 compliant with MSL 1 rating.

Compliance and Certification: All three parts maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Selection should be based on specific panel mounting hole pattern requirements and voltage margin requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JCEC?

A: Yes. The RFSSMAA2JEGA is a parametric equivalent with identical electrical specifications, mechanical configuration, and compliance certifications. Both parts feature 2-hole flange mounting, 50 Ohm impedance, 40 GHz maximum frequency, and 350 V voltage rating. No functional differences exist between these parts.

Q: What is the primary difference between RFSSMAA2JCEC and RFSSMAA4JCCA?

A: The primary difference is the mounting feature. The RFSSMAA2JCEC uses a 2-hole flange configuration, while the RFSSMAA4JCCA uses a 4-hole flange configuration. The RFSSMAA4JCCA also has a 335 V voltage rating compared to 350 V in the RFSSMAA2JCEC. All other electrical and mechanical parameters are identical.

Q: Is the 15 V voltage rating difference between RFSSMAA2JCEC (350 V) and RFSSMAA4JCCA (335 V) significant?

A: The voltage rating difference is not significant for standard 50 Ohm RF coaxial connector applications. Both ratings exceed typical operating voltages in RF systems. Selection between these parts should be based on mounting hole pattern requirements rather than voltage margin considerations.

Q: Can RFSSMAA4JCCA be used in applications designed for RFSSMAA2JCEC?

A: RFSSMAA4JCCA can be used only if the panel mounting design accommodates a 4-hole flange pattern. The electrical performance is equivalent, but the mechanical mounting configuration must match the application requirements. If the panel is designed for 2-hole mounting, RFSSMAA4JCCA is not suitable without panel modification.

Q: Are all three parts ROHS3 compliant?

A: Yes. RFSSMAA2JCEC, RFSSMAA2JEGA, and RFSSMAA4JCCA are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level.

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

A: All three parts operate across the temperature range of -65°C to 165°C, providing compatibility across industrial and aerospace applications.

Q: Do these connectors support the same frequency range?

A: Yes. All three parts support a maximum frequency of 40 GHz with 50 Ohm impedance, maintaining RF performance equivalence across the connector family.
