Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RF55-33B-T-00-50-A-SH are qualified based on the following critical parameters that must remain constant:

• Connector Style: SMB, Fakra
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Through Hole, Right Angle
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 4 GHz
• Number of Ports: 1
• Operating Temperature: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variations in center contact material, body finish, and body material are permitted when all electrical and mechanical interface parameters remain equivalent. The substitute parts RF55-23B-T-00-50-G-A-SH and RF55-32B-T-00-50-A-SH satisfy these criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance. Selection between RF55-33B-T-00-50-A-SH, RF55-23B-T-00-50-G-A-SH, and RF55-32B-T-00-50-A-SH is determined by availability and material specifications. RF55-23B-T-00-50-G-A-SH features brass center contact material with gold body finish. RF55-32B-T-00-50-A-SH uses phosphor bronze center contact with tin and nickel body finish. RF55-33B-T-00-50-A-SH combines phosphor bronze center contact with gold and nickel body finish. All parts satisfy identical electrical interface requirements and operating conditions.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts maintain equivalent electrical and mechanical parameters including 50 Ohm impedance, 4 GHz maximum frequency, through-hole right-angle solder termination, and identical operating temperature range. Differences in center contact material (brass versus phosphor bronze) and body finish do not affect connector interface compatibility.

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

A: Both parts use phosphor bronze center contact material. The primary difference is body finish: RF55-32B-T-00-50-A-SH features tin and nickel finish, while RF55-33B-T-00-50-A-SH features gold and nickel finish. Electrical performance and mechanical interface remain equivalent.

Q: Are all three parts ROHS3 compliant?

A: Yes. RF55-33B-T-00-50-A-SH, RF55-23B-T-00-50-G-A-SH, and RF55-32B-T-00-50-A-SH are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: What packaging is supplied for these connectors?

A: All three parts are supplied in Tray packaging.

Q: Do these connectors support frequencies above 4 GHz?

A: No. The maximum frequency specification for all three parts is 4 GHz. Applications requiring higher frequency operation require alternative connector designs.
