Engineering Selection Recommendations

All three parts—RF55-33E-T-00-50-A-SH, RF55-23E-T-00-50-G-A-SH, and RF55-32E-T-00-50-A-SH—are Active status components with full RoHS3 compliance and REACH unaffected certification. Selection among these substitutes is based on availability and material specifications rather than functional performance differences.

RF55-33E-T-00-50-A-SH features Phosphor Bronze center contacts with Gold and Nickel body finish. RF55-23E-T-00-50-G-A-SH uses Brass center contacts with Gold body finish and includes PTFE dielectric material specification. RF55-32E-T-00-50-A-SH combines Phosphor Bronze center contacts with Tin and Nickel body finish. All three maintain identical electrical impedance, frequency rating, temperature operating range, and solder termination configuration.

Current inventory levels are: RF55-33E-T-00-50-A-SH (1176 pcs), RF55-23E-T-00-50-G-A-SH (793 pcs), and RF55-32E-T-00-50-A-SH (1059 pcs).

Frequently Asked Questions (FAQ)

Q: Can RF55-23E-T-00-50-G-A-SH be used as a direct replacement for RF55-33E-T-00-50-A-SH?

A: Yes. Both parts share identical connector style (SMB, Fakra plug), impedance (50 Ohms), mounting configuration (through hole, right angle), termination method (solder), frequency rating (4 GHz maximum), and operating temperature range (-40°C to 85°C). The difference in center contact material (Brass vs. Phosphor Bronze) and body finish does not affect electrical performance within specified parameters.

Q: What is the difference between RF55-32E-T-00-50-A-SH and RF55-33E-T-00-50-A-SH?

A: Both parts use Phosphor Bronze center contacts and share all critical electrical and mechanical specifications. The primary difference is body finish: RF55-33E-T-00-50-A-SH has Gold and Nickel finish, while RF55-32E-T-00-50-A-SH has Tin and Nickel finish. This material variation does not affect functional interchangeability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RF55-33E-T-00-50-A-SH, RF55-23E-T-00-50-G-A-SH, and RF55-32E-T-00-50-A-SH are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What packaging format is used for these parts?

A: All three parts are supplied in Tray packaging.

Q: Can these connectors be used in applications exceeding 4 GHz?

A: No. The maximum frequency rating for all three parts is 4 GHz. Applications requiring higher frequency operation require alternative component selection.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -40°C to 85°C. Applications outside this range require alternative components.
