RFSSMAA2JEGC Equivalent & Substitute Parts

Part Overview

The RFSSMAA2JEGC 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 1097 pieces in stock inventory. 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 voltage ratings permit substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFSSMAA2JEGC are identified based on electrical and mechanical parameter equivalence within the SSMA connector family. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Connector style: SSMA
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 40 GHz
• Contact termination: Compression
• Shield termination: Screw
• Operating temperature range: -65°C ~ 165°C
• Mating cycles: 500

Mechanical Parameters (Must Match):

• Mounting type: Panel Mount
• Center contact material: Beryllium Copper
• Body material: Stainless Steel
• Dielectric material: Polytetrafluoroethylene (PTFE)

Allowable Variations:

• Mounting feature configuration (flange hole count: 2-hole vs. 4-hole)
• Voltage rating (350 V vs. 335 V)

The RFSSMAA2JEGC maintains full electrical and mechanical compatibility with substitute parts RFSSMAA2JEGA and RFSSMAA4JCCA. The primary difference between RFSSMAA2JEGC and RFSSMAA2JEGA is manufacturing origin or internal specification revision while maintaining identical external parameters. The RFSSMAA4JCCA variant differs in mounting feature configuration (4-hole flange versus 2-hole flange) and has a marginally lower voltage rating of 335 V versus 350 V.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RFSSMAA2JEGC, RFSSMAA2JEGA, and RFSSMAA4JCCA—are active production components manufactured by Bulgin with ROHS3 compliance and EAR99 export classification. Selection between these parts is determined by specific application requirements:

RFSSMAA2JEGC Selection Criteria: Select this part when a 2-hole flange mounting configuration is required and the application operates at or near the maximum 350 V rating. This part has the highest current inventory availability at 1097 pieces.

RFSSMAA2JEGA Selection Criteria: This part is electrically and mechanically identical to RFSSMAA2JEGC with the same 2-hole flange configuration and 350 V voltage rating. Selection between RFSSMAA2JEGC and RFSSMAA2JEGA is based on procurement source or internal specification revision requirements. Inventory availability is 978 pieces.

RFSSMAA4JCCA Selection Criteria: Select this part when a 4-hole flange mounting configuration is required for panel integration. The voltage rating of 335 V is suitable for applications not requiring the full 350 V specification. This part has 1026 pieces in inventory. The 4-hole flange provides additional mechanical stability in high-vibration or high-stress mounting environments.

All three parts maintain identical RF performance characteristics, operating temperature range, mating cycle rating, and material composition. Substitution is permissible where mounting hole configuration and voltage rating requirements are compatible with the application design.

Frequently Asked Questions (FAQ)

Q: Can RFSSMAA2JEGA be used as a direct replacement for RFSSMAA2JEGC?

A: Yes. RFSSMAA2JEGA is a direct parametric equivalent with identical electrical specifications, mechanical configuration, voltage rating (350 V), and 2-hole flange mounting feature. Both parts are ROHS3 compliant and maintain the same operating temperature range and mating cycle rating.

Q: What is the primary difference between RFSSMAA2JEGC and RFSSMAA4JCCA?

A: The primary difference is the mounting feature configuration. RFSSMAA2JEGC uses a 2-hole flange, while RFSSMAA4JCCA uses a 4-hole flange. Additionally, RFSSMAA4JCCA has a voltage rating of 335 V compared to 350 V for RFSSMAA2JEGC. All other electrical and mechanical parameters are identical.

Q: Can RFSSMAA4JCCA be substituted for RFSSMAA2JEGC in existing designs?

A: Substitution is permissible only if the application design accommodates a 4-hole flange mounting configuration and does not require operation at voltages exceeding 335 V. The RF performance characteristics, impedance, frequency range, and operating temperature specifications are fully compatible.

Q: Are all three parts RoHS compliant?

A: Yes. RFSSMAA2JEGC, RFSSMAA2JEGA, and RFSSMAA4JCCA are all ROHS3 compliant and suitable for applications requiring environmental compliance certification.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.

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, making them suitable for identical RF applications.

Q: What is the mating cycle rating for these connectors?

A: All three parts are rated for 500 mating cycles, indicating the same mechanical durability and connection reliability.

Q: Are there any material differences between the three parts?

A: No. All three parts use identical materials: beryllium copper center contacts, stainless steel body, and polytetrafluoroethylene (PTFE) dielectric material.
