Engineering Selection Recommendations

Primary Substitute - Same Manufacturer (Bulgin):

RF292A4JCCA is the direct Bulgin equivalent with identical electrical and thermal specifications. The distinction is the mounting hole configuration: four holes instead of two. This part is suitable for applications requiring additional mechanical stability or different PCB layout requirements. Both parts maintain ROHS3 compliance and identical operating parameters.

Secondary Substitutes - WITHWAVE PM03FS Series:

The WITHWAVE PM03FS series (PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS060, PM03FS061, PM03FS062, PM03FS063) provides electrical equivalence with the following considerations:

All PM03FS parts feature screw-type shield termination instead of solder termination. This termination method is functionally equivalent for RF performance at 50 ohms and 40 GHz operation.
Extended operating temperature range (-40°C to 135°C) provides thermal margin beyond the RF292A2JCEES specification (-40°C to 85°C).
Body material variations exist: PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS061, and PM03FS063 use stainless steel; PM03FS060 and PM03FS062 use brass with tin and nickel finish.
All PM03FS parts include gold plating on center contacts, enhancing corrosion resistance compared to the unplated beryllium copper of the main part.
All substitute parts are active products with confirmed inventory availability.

Selection Criteria:

Choose RF292A4JCCA when maintaining identical Bulgin manufacturing and solder shield termination is required, and when four mounting holes accommodate the mechanical design.

Choose PM03FS series parts when extended temperature operation is required, when screw-type shield termination is acceptable, or when alternative body material specifications align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can PM03FS series connectors replace RF292A2JCEES in all applications?

A: PM03FS series parts are electrically equivalent at 50 ohms impedance and 40 GHz frequency operation. The primary difference is shield termination method: PM03FS uses screw termination while RF292A2JCEES uses solder termination. Both methods provide equivalent RF performance. Verify that your assembly process accommodates screw-type termination if substituting. Extended operating temperature range of PM03FS parts (-40°C to 135°C) exceeds the main part specification and is suitable for higher temperature environments.

Q: What is the difference between RF292A2JCEES and RF292A4JCCA?

A: Both parts are manufactured by Bulgin and share identical electrical specifications: 2.92mm jack, female socket, 50 ohms, 40 GHz maximum frequency, solder termination, and -40°C to 85°C operating range. The distinction is mounting hole count: RF292A2JCEES has two mounting holes while RF292A4JCCA has four mounting holes. Select based on your PCB layout and mechanical mounting requirements.

Q: Are there compliance differences between the main part and substitutes?

A: All listed parts maintain ROHS3 compliance. The main part RF292A2JCEES and Bulgin substitute RF292A4JCCA are both ROHS3 compliant. WITHWAVE PM03FS series parts are active products with equivalent compliance status. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: Does center contact plating affect RF performance?

A: Center contact plating does not alter RF electrical performance at 50 ohms impedance and 40 GHz operation. The RF292A2JCEES features unplated beryllium copper contacts. WITHWAVE PM03FS series parts include gold plating on beryllium copper contacts, which enhances corrosion resistance and contact durability during mating cycles. Both configurations meet the electrical specifications.

Q: What is the significance of body material differences in PM03FS parts?

A: PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS061, and PM03FS063 use stainless steel bodies, matching the RF292A2JCEES material. PM03FS060 and PM03FS062 use brass bodies with tin and nickel finish. Both materials provide adequate structural integrity and RF shielding. Stainless steel offers superior corrosion resistance in harsh environments, while brass with plating provides cost-effective performance in standard applications. Selection depends on environmental exposure and cost considerations.

Q: Can I use PM03FS parts in applications requiring solder shield termination?

A: PM03FS series parts feature screw-type shield termination, not solder termination. If your assembly process specifically requires solder termination, use RF292A2JCEES or RF292A4JCCA. If screw termination is acceptable or preferred for your mechanical design, PM03FS parts are suitable substitutes with equivalent RF performance.

Q: What inventory considerations apply to these substitutes?

A: RF292A2JCEES has 954 pieces in stock. RF292A4JCCA has 1209 pieces in stock. WITHWAVE PM03FS series inventory ranges from 769 to 1144 pieces depending on specific part number. All parts are listed as new original stock. Verify current availability with your supplier for production quantities.
