RFSSMAA2JCEB Equivalent & Substitute Parts

Part Overview

The RFSSMAA2JCEB is an SSMA Connector Jack with female socket configuration manufactured by Bulgin. This coaxial RF connector is designed for 50 Ohms impedance applications with panel mount flange installation and compression contact termination. The connector operates across a frequency range up to 40 GHz and maintains electrical performance across an operating temperature range of -65°C to 165°C.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for SSMA coaxial connector applications. Alternative models may be required due to inventory availability, specific mounting hole configurations, or procurement lead times while maintaining full functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA2JCEB are qualified based on the following critical parameters that define functional equivalence in SSMA coaxial connector applications:

Electrical Equivalence Parameters:

• Connector Style: SSMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 40 GHz
• Operating Temperature: -65°C ~ 165°C
• Contact Termination: Compression
• Shield Termination: Screw

Mechanical Equivalence Parameters:

• Mounting Type: Panel Mount
• Fastening Type: Threaded
• Center Contact Material: Beryllium Copper
• Body Material: Stainless Steel
• Dielectric Material: Polytetrafluoroethylene (PTFE)

Compliance Parameters:

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

Substitute parts maintain these core parameters while allowing variation in mounting hole configuration (flange hole count) and minor voltage rating differences within acceptable operating ranges for the application category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and identical moisture sensitivity classification. Selection between RFSSMAA2JCEB, RFSSMAA2JEGA, and RFSSMAA4JCCA is determined by panel mounting hole configuration requirements.

RFSSMAA2JCEB and RFSSMAA2JEGA are functionally identical with 2-hole flange mounting configurations. Both parts support the full 40 GHz frequency range, maintain 50 Ohms impedance, and operate across -65°C to 165°C. The RFSSMAA2JCEB carries a 350 V rating. These parts are interchangeable for applications requiring 2-hole panel mount installation.

RFSSMAA4JCCA provides a 4-hole flange mounting configuration while maintaining all electrical specifications including 40 GHz maximum frequency and 50 Ohms impedance. The voltage rating is 335 V, which remains within acceptable operating parameters for standard SSMA applications. This part is selected when panel mounting design requires four-hole fastening.

All substitute parts are manufactured by Bulgin, share identical contact and shield termination methods, and utilize the same material composition for center contact, body, and dielectric elements. Compliance certifications and reliability metrics (500 mating cycles) are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JCEB?

A: Yes. Both parts are SSMA Jack female socket connectors with identical electrical and mechanical specifications including 50 Ohms impedance, 40 GHz maximum frequency, compression contact termination, and 2-hole flange panel mount configuration. Both maintain 350 V voltage rating and operate across -65°C to 165°C.

Q: What is the primary difference between the 2-hole and 4-hole mounting variants?

A: The RFSSMAA2JCEB and RFSSMAA2JEGA feature 2-hole flange mounting, while RFSSMAA4JCCA provides 4-hole flange mounting. All other electrical and mechanical parameters remain equivalent. Selection depends on panel design and fastening hole layout requirements.

Q: Does the voltage rating difference between RFSSMAA2JCEB (350 V) and RFSSMAA4JCCA (335 V) affect compatibility?

A: Both voltage ratings are within acceptable operating parameters for SSMA connector applications. The 15 V difference does not impact functional compatibility in standard RF circuit applications. Selection should be based on specific circuit voltage requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RFSSMAA2JCEB, RFSSMAA2JEGA, and RFSSMAA4JCCA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: What is the maximum operating frequency for all substitute parts?

A: All three parts support 40 GHz maximum frequency operation, maintaining full RF performance across the SSMA connector specification range.

Q: Can these connectors be used interchangeably in high-frequency applications?

A: Yes, within the constraints of mounting hole configuration. All parts maintain 50 Ohms impedance, 40 GHz frequency capability, and identical contact materials (Beryllium Copper center contact with PTFE dielectric). Selection between 2-hole and 4-hole variants is determined by panel mounting design requirements only.
