Parameter Comparison

Engineering Selection Recommendations

000-49000 (Standard Configuration)

Select this part for applications operating within the -55°C to 85°C temperature range where standard silver plating and copolymer dielectric material meet performance requirements. This configuration provides the baseline specification for N Type 50 ohm panel mount receptacles with solder cup termination.

000-49000-RFX (Nickel Body Finish with Gold Plating)

Select this part for applications requiring extended operating temperature range (-65°C to 165°C) and enhanced corrosion resistance through nickel body finish. The gold-plated center contact provides superior contact reliability in high-cycle mating applications. The PTFE dielectric material offers improved electrical performance at elevated temperatures.

000-49000-SRFX (Silver Body Finish with Gold Plating)

Select this part for applications requiring extended operating temperature range (-65°C to 165°C) with silver body finish and gold-plated center contact. The PTFE dielectric material provides enhanced thermal stability. This configuration combines the aesthetic properties of silver finish with the performance benefits of gold plating and PTFE dielectric.

All three parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory conformance across all substitute options.

Frequently Asked Questions (FAQ)

Q: Can 000-49000-RFX be used as a direct replacement for 000-49000?

A: Yes. The 000-49000-RFX maintains all core electrical and mechanical parameters including connector style, impedance, frequency rating, and voltage rating. The differences in body finish (nickel vs. silver), center contact plating (gold vs. silver), and dielectric material (PTFE vs. copolymer) do not affect functional compatibility. The extended operating temperature range (-65°C to 165°C) provides additional capability for demanding environments.

Q: What is the primary difference between 000-49000-RFX and 000-49000-SRFX?

A: The primary difference is body finish. The 000-49000-RFX features a nickel body finish, while the 000-49000-SRFX features a silver body finish. Both parts share identical center contact plating (gold), dielectric material (PTFE), and operating temperature range (-65°C to 165°C). Selection between these two depends on application-specific requirements for corrosion resistance and aesthetic considerations.

Q: Are there any impedance or frequency differences between these parts?

A: No. All three parts (000-49000, 000-49000-RFX, and 000-49000-SRFX) maintain identical impedance (50 ohms) and maximum frequency rating (11 GHz). These core RF parameters are fixed across all substitute configurations.

Q: Which part should be selected for high-temperature applications?

A: Both 000-49000-RFX and 000-49000-SRFX are rated for operating temperatures up to 165°C, compared to 85°C for the standard 000-49000. Either substitute part is suitable for high-temperature applications. Selection between the two depends on body finish requirements (nickel vs. silver).

Q: Do all parts have the same mating cycle rating?

A: Yes. All three parts are rated for 500 mating cycles, indicating identical mechanical durability and contact reliability specifications.

Q: Are there compliance differences between the substitute parts?

A: No. All three parts maintain identical RoHS3 compliance and REACH affected status, ensuring regulatory conformance across all configurations.

Q: What is the significance of PTFE dielectric material in the substitute parts?

A: PTFE (Polytetrafluoroethylene) dielectric material in 000-49000-RFX and 000-49000-SRFX provides improved electrical performance and thermal stability compared to the copolymer dielectric in the standard 000-49000. This enhancement supports the extended operating temperature range and is particularly beneficial in high-frequency applications.

Q: Can these parts be intermixed in the same assembly?

A: Yes. All three parts are mechanically and electrically compatible due to identical connector style, type, impedance, and mounting specifications. Intermixing is permissible from a functional standpoint, though design consistency may warrant using a single part number throughout an assembly.
