Parameter Comparison

Engineering Selection Recommendations

All three parts—R125154002, R124154003W, and R125154000—are Active products manufactured by Radiall USA, Inc., and are ROHS3 compliant with EAR99 export classification. Selection between these parts is determined by application-specific requirements for voltage rating and mating cycle durability.

R125154002 provides a balanced specification with 335 V rating and 500 mating cycles, suitable for standard RF applications requiring moderate voltage handling and connector durability.

R124154003W features a brass body material with a 250 V voltage rating and 100 mating cycles. This part is appropriate for applications with lower voltage requirements and less frequent connector engagement cycles. The brass body construction differs from the stainless steel body of the main part.

R125154000 offers the highest voltage rating at 500 V with 500 mating cycles and maintains stainless steel body construction identical to the main part. This configuration is suitable for high-voltage RF applications requiring extended connector lifecycle.

All three parts maintain identical RF performance characteristics, impedance, frequency rating, and operating temperature range. Selection should be based on the specific voltage and mating cycle requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can R124154003W be used as a direct replacement for R125154002?

A: R124154003W is electrically and mechanically compatible for RF applications up to 12.4 GHz with 50 Ohm impedance. However, it has a lower voltage rating (250 V versus 335 V) and reduced mating cycle specification (100 versus 500). Substitution is valid only if the application voltage does not exceed 250 V and connector engagement cycles remain below 100.

Q: What is the primary difference between R125154002 and R125154000?

A: Both parts share identical stainless steel body construction and 500 mating cycle ratings. The primary difference is voltage rating: R125154002 is rated for 335 V while R125154000 is rated for 500 V. R125154000 is suitable for applications requiring higher voltage handling capability.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts—R125154002, R124154003W, and R125154000—are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: Does body material affect RF performance?

A: Body material composition (stainless steel versus brass) does not affect the RF electrical performance of these connectors. Both materials maintain the specified 50 Ohm impedance and 12.4 GHz frequency rating. Material selection impacts mechanical durability and corrosion resistance characteristics.

Q: What is the significance of mating cycle ratings?

A: Mating cycle ratings indicate the number of times a connector can be engaged and disengaged while maintaining electrical and mechanical specifications. R125154002 and R125154000 support 500 cycles, while R124154003W supports 100 cycles. Applications with frequent connector changes require higher mating cycle specifications.

Q: Are these connectors compatible with RG-402 cable only?

A: These connectors are specified for RG-402 (.141" semi-rigid) cable. All three parts maintain this cable group specification and are not interchangeable with connectors designed for different cable diameters or types.

Q: What operating temperature range applies to all three parts?

A: All three parts operate across the identical temperature range of -65°C to 105°C, ensuring consistent thermal performance across all substitute options.
