Parameter Comparison

Engineering Selection Recommendations

All three parts—RF55-33A-T-00-50-A-SH, RF55-23A-T-00-50-G-A-SH, and RF55-32A-T-00-50-A-SH—maintain Active product status and full compliance with ROHS3 and REACH regulations. Each part carries identical electrical specifications (50 Ohm impedance, 4 GHz maximum frequency) and mechanical form factors (SMB Fakra plug, through-hole right-angle solder mount).

Variations in center contact material (Phosphor Bronze versus Brass) and body finish (Gold/Nickel, Gold only, or Tin/Nickel) do not alter functional interchangeability within the specified operating temperature range of -40°C to 85°C. Selection among these parts may be driven by inventory availability, supply chain considerations, or specific finish requirements for corrosion resistance in particular environmental applications.

Frequently Asked Questions (FAQ)

Q: Can RF55-23A-T-00-50-G-A-SH replace RF55-33A-T-00-50-A-SH in existing designs?

A: Yes. Both parts share identical electrical parameters (50 Ohm impedance, 4 GHz frequency rating), mechanical mounting configuration (through-hole right-angle), and connector interface (SMB Fakra male plug). The difference in center contact material (Brass versus Phosphor Bronze) and body finish does not affect electrical performance or mechanical fit.

Q: What is the significance of the different body finishes across these parts?

A: Body finish variations (Gold/Nickel, Gold only, Tin/Nickel) provide different corrosion resistance profiles. Selection depends on environmental exposure and application requirements. All finishes maintain compliance with ROHS3 and operate within the specified -40°C to 85°C temperature range.

Q: Are all three parts suitable for high-frequency RF applications?

A: Yes. All three parts are rated to 4 GHz maximum frequency and maintain 50 Ohm impedance, making them suitable for identical RF circuit applications.

Q: Do packaging differences affect substitution?

A: No. All three parts are supplied in Tray packaging and carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), ensuring equivalent handling and storage requirements.

Q: Are there any regulatory or compliance differences between these parts?

A: No. All three parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8536.69.4010.
