Substitute Part Grouping Explanation

Substitution of the 02K721-40MS3 is determined by strict equivalence across the following critical parameters:

Connector style (2.92mm)
Connector type (Jack, Female Socket)
Impedance (50 Ohms)
Contact termination (Compression)
Shield termination (Screw)
Mounting type (Panel Mount with Flange)
Fastening type (Threaded)
Frequency rating (40 GHz maximum)
Number of ports (1)

All identified substitute parts match these core electrical and mechanical specifications. Variations in body material, dielectric material, operating temperature range, and insertion loss are noted but do not prevent functional substitution when application requirements permit.

Engineering Selection Recommendations

All substitute parts listed are active production components with equivalent 2.92mm jack female socket configuration, 50 ohm impedance, and 40 GHz frequency rating. Selection among substitutes depends on application-specific requirements:

Rosenberger 02K722-40MS3 provides direct manufacturer equivalence with identical mechanical and electrical interface. Taoglas PCB.292FST series (2H, 4H variants) and VMPCB.292FST.A.XS offer brass body construction with extended low-temperature capability (-55°C minimum) and are ROHS3 compliant. Bulgin RF292A2JEGA and RF292DJB provide stainless steel construction with extended operating temperature ranges (-40°C to 85°C and -55°C to 125°C respectively) and are ROHS3 compliant. WITHWAVE VC03FS001 and VC03FS002 provide stainless steel construction with gold plating and active product status.

All parts maintain 50 ohm impedance, compression contact termination, screw shield termination, panel mount flange configuration, and 500 mating cycle rating. Insertion loss specifications are provided for Rosenberger and Taoglas parts; Bulgin and WITHWAVE specifications are not documented in available data.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 02K721-40MS3 with any of the listed parts?

A: Yes. All listed parts share the critical substitution parameters: 2.92mm connector style, jack female socket type, 50 ohm impedance, compression contact termination, screw shield termination, panel mount flange mounting, and 40 GHz frequency rating. Mechanical and electrical interfaces are equivalent.

Q: What are the differences between Rosenberger and Taoglas substitutes?

A: Rosenberger 02K721-40MS3 and 02K722-40MS3 use stainless steel bodies with PTFE dielectric and operate from 0°C to 85°C. Taoglas PCB.292FST and VMPCB.292FST series use brass bodies with gold finish, PEI dielectric, and operate from -55°C to 50°C. Taoglas parts specify 0.38dB insertion loss versus 0.25dB for the main part.

Q: Are Bulgin RF292 parts suitable for extended temperature applications?

A: Yes. Bulgin RF292A2JEGA operates from -40°C to 85°C, and RF292DJB operates from -55°C to 125°C, providing wider temperature ranges than the 02K721-40MS3 (0°C to 85°C). Both are ROHS3 compliant and maintain 50 ohm impedance and 40 GHz frequency rating.

Q: What compliance certifications apply to all substitutes?

A: All listed parts are ROHS3 compliant and active production status. Rosenberger, Taoglas, and Bulgin parts carry ROHS3 certification. WITHWAVE VC03FS001 and VC03FS002 are active but compliance documentation is not provided in available data.

Q: Does insertion loss affect substitution suitability?

A: Insertion loss is a performance characteristic, not a substitution criterion. The 02K721-40MS3 specifies 0.25dB. Taoglas parts specify 0.38dB. Bulgin and WITHWAVE insertion loss is not documented. Selection should account for application insertion loss budgets.

Q: Are there packaging or lead time considerations?

A: All parts are available in bulk packaging. Inventory levels vary: 02K721-40MS3 (1114 pcs), 02K722-40MS3 (759 pcs), Taoglas variants (770-1034 pcs), Bulgin variants (783-863 pcs), and WITHWAVE variants (1027-1110 pcs). Availability should be confirmed with suppliers for specific procurement timelines.
