Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R124153003 is determined by strict adherence to the following core parameters:

Critical Parameters (Must Match):

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Contact Termination: Solder
• Shield Termination: Solder
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line), Right Angle
• Cable Group: RG-405 (.085" Semi Rigid)
• Fastening Type: Threaded
• Frequency - Max: 12.4 GHz
• Number of Ports: 1
• Operating Temperature: -65°C ~ 105°C
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Packaging (Bulk or Box)
• Body Material (Brass or Stainless Steel)
• Mating Cycles (100 or 500)
• Voltage Rating (250 V or 335 V)
• Includes (with or without end cap)

All four substitute parts (R124153003W, R125153000, R125153000W, R125153002) maintain identical RF performance characteristics and are functionally interchangeable within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the primary part R124153003.

R124153003W is a direct parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Box versus Bulk). This part is suitable for applications requiring boxed delivery while maintaining all RF performance characteristics.

R125153000 and R125153002 feature stainless steel body construction compared to the brass body of R124153003, providing enhanced durability for applications requiring extended mating cycles (500 cycles versus 100 cycles). Both parts maintain the 335 V voltage rating and all RF specifications. R125153002 includes an end cap accessory.

R125153000W is a stainless steel variant with boxed packaging and 500 mating cycles. The voltage rating is reduced to 250 V, which remains suitable for standard RF applications but should be evaluated against specific circuit requirements if higher voltage margins are necessary.

Selection between substitute parts should be based on packaging requirements (Bulk or Box), body material durability needs, mating cycle expectations, and voltage rating specifications for the intended application.

Frequently Asked Questions (FAQ)

Q: Can R124153003W be used as a direct replacement for R124153003?

A: Yes. R124153003W is a parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Box instead of Bulk). All RF performance characteristics, impedance, frequency rating, and operating temperature range are identical.

Q: What is the primary difference between the brass body (R124153003) and stainless steel body (R125153000, R125153000W, R125153002) variants?

A: The stainless steel body variants support 500 mating cycles compared to 100 mating cycles for the brass body variant. Both materials maintain identical RF performance at 50 Ohms impedance and 12.4 GHz maximum frequency. Stainless steel construction provides enhanced durability for applications requiring frequent connector engagement and disengagement.

Q: Is R125153000W suitable for high-voltage applications?

A: R125153000W has a voltage rating of 250 V, which is lower than the 335 V rating of R124153003, R124153003W, R125153000, and R125153002. Applications requiring voltage margins above 250 V should use alternative parts with the 335 V rating.

Q: What does the "W" designation indicate in part numbers R124153003W and R125153000W?

A: The "W" designation indicates Box packaging format. Parts without the "W" designation are supplied in Bulk packaging. All electrical and mechanical specifications remain identical between "W" and non-"W" variants of the same base part number.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed (R124153003, R124153003W, R125153000, R125153000W, R125153002) are ROHS3 compliant and suitable for applications with RoHS regulatory requirements.

Q: What is included with R125153002?

A: R125153002 includes 2 pieces: 1 Connector and 1 End Cap. Other variants include only the connector without the end cap accessory.

Q: Can these connectors be used with cable types other than RG-405?

A: All listed parts are specified for RG-405 (.085" semi-rigid) cable. Use only with this cable group to maintain the specified 50 Ohms impedance and RF performance characteristics.

Q: What is the operating temperature range for all substitute parts?

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