Part Overview

The RF292A2JDFES is a 2.92mm coaxial connector jack with female socket configuration manufactured by Bulgin. This panel mount, through-hole solder connector operates at 50 ohms impedance with a maximum frequency rating of 40 GHz. The connector features a flanged mounting design with two mounting holes and is rated for 500 mating cycles. The part is currently active in production status with 1106 units in stock. Equivalent and substitute parts are identified for applications requiring alternative mounting configurations, extended operating temperature ranges, or different body material specifications while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RF292A2JDFES is determined by the following core parameters that must remain constant across all equivalent parts:

Critical Electrical Parameters:

• Connector style: 2.92mm
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 40 GHz
• Contact termination: Solder

Critical Mechanical Parameters:

• Mounting type: Panel Mount
• Mounting feature: Flange
• Fastening type: Threaded
• Center contact material: Beryllium Copper

Allowable Variations:

• Number of mounting holes (2-hole vs. 4-hole configurations)
• Shield termination method (Solder vs. Screw)
• Body material (Stainless Steel vs. Brass with finish)
• Center contact plating (presence or type)
• Operating temperature range (extended ranges acceptable)
• Dielectric material specification

All substitute parts listed maintain electrical compatibility at 50 ohms impedance and 40 GHz maximum frequency. Variations in body material, plating, and temperature ratings do not affect RF performance within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Same Manufacturer (Bulgin):

RF292A4JCCA is the direct Bulgin equivalent with identical electrical specifications and operating temperature range. The distinction is the mounting hole configuration: RF292A4JCCA provides four mounting holes versus the two holes on RF292A2JDFES. Both parts maintain ROHS3 compliance and identical impedance, frequency, and voltage ratings. Selection between these two Bulgin variants depends solely on PCB layout requirements and mechanical mounting hole spacing.

Cross-Manufacturer Substitutes (WITHWAVE CO LTD):

The PM03FS series connectors (PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS060, PM03FS061, PM03FS062, PM03FS063) provide electrical equivalence with extended operating temperature capability to 135°C. These parts maintain 50 ohms impedance and 40 GHz frequency rating. The primary differences are:

• Shield termination uses screw fastening instead of solder
• Center contact plating is gold-plated
• Body material varies between stainless steel and brass with tin/nickel finish
• Operating temperature range extends to 135°C

All WITHWAVE parts are active production status with inventory availability ranging from 769 to 1144 units.

Selection Criteria:

Choose RF292A4JCCA when four mounting holes are required and Bulgin sourcing is preferred. Choose WITHWAVE PM03FS series when extended temperature operation to 135°C is required or when screw-based shield termination is preferred over solder termination. All listed substitutes maintain full RF compatibility at 50 ohms and 40 GHz within their specified operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can RF292A2JDFES be replaced with RF292A4JCCA in all applications?

A: RF292A4JCCA is electrically and mechanically equivalent with one exception: it features four mounting holes instead of two. Substitution is valid only if the PCB layout accommodates four mounting holes. Both parts share identical impedance (50 ohms), frequency rating (40 GHz), operating temperature (-40°C to 85°C), and voltage rating (250 V).

Q: What is the primary difference between Bulgin RF292 series and WITHWAVE PM03FS series?

A: Both series maintain identical 50 ohms impedance and 40 GHz frequency rating. The WITHWAVE PM03FS series extends operating temperature to 135°C compared to 85°C for Bulgin RF292 series. WITHWAVE parts use screw-based shield termination and gold-plated center contacts, while Bulgin uses solder-based shield termination. Body material varies within the PM03FS series between stainless steel and brass.

Q: Are WITHWAVE PM03FS connectors suitable for high-temperature applications?

A: Yes. The PM03FS series is rated for -40°C to 135°C operating temperature, extending 50°C above the RF292A2JDFES specification. This extended range applies to all PM03FS variants listed. Applications requiring operation above 85°C must use WITHWAVE parts.

Q: Does shield termination method affect RF performance?

A: Shield termination method (solder versus screw) does not affect RF electrical performance at 50 ohms impedance and 40 GHz frequency. Selection between solder and screw termination is based on assembly process requirements and mechanical design constraints.

Q: What is the inventory status for substitute parts?

A: RF292A4JCCA (Bulgin): 1209 units. PM03FS056: 909 units. PM03FS057: 958 units. PM03FS058: 1009 units. PM03FS059: 997 units. PM03FS060: 769 units. PM03FS061: 1144 units. PM03FS062: 819 units. PM03FS063: 967 units. All parts are in stock as new original inventory.

Q: Are all substitute parts RoHS3 compliant?

A: RF292A2JDFES and RF292A4JCCA are explicitly ROHS3 compliant. RoHS compliance status for WITHWAVE PM03FS series is not specified in the provided data.

Q: Can RF292A2JDFES be used in applications requiring 500 mating cycles?

A: Yes. RF292A2JDFES is rated for 500 mating cycles. RF292A4JCCA also supports 500 mating cycles. Mating cycle specifications for WITHWAVE PM03FS series are not provided.

Q: What body material options are available in substitute parts?

A: RF292A2JDFES uses stainless steel. RF292A4JCCA uses stainless steel. WITHWAVE PM03FS series offers stainless steel (PM03FS056, PM03FS057, PM03FS058, PM03FS059, PM03FS061, PM03FS063) and brass with tin/nickel finish (PM03FS060, PM03FS062).
