The RF55-33H-T-00-50-A-SH features phosphor bronze center contact material with nickel body finish, while the RF55-23H-T-00-50-G-A-SH features brass center contact material with gold body finish. Both configurations maintain 50 Ohm impedance and 4 GHz frequency performance. Current inventory shows 817 units of RF55-33H-T-00-50-A-SH and 1158 units of RF55-23H-T-00-50-G-A-SH available.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors maintain identical electrical specifications (50 Ohm impedance, 4 GHz maximum frequency), mechanical interface (SMB Fakra plug, male pin, through-hole right-angle solder termination), and environmental ratings (-40°C to 85°C operating temperature, MSL 1). Direct substitution is supported without circuit redesign.

Q: What are the material differences between these two parts?

A: RF55-33H-T-00-50-A-SH uses phosphor bronze center contact with nickel body finish. RF55-23H-T-00-50-G-A-SH uses brass center contact with gold body finish. Both achieve equivalent electrical performance and comply with identical regulatory standards.

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

A: Both parts are rated for operation up to 4 GHz and are designed for 50 Ohm coaxial RF applications. Frequency performance is equivalent across both part numbers.

Q: What is the significance of the Code H feature designation?

A: Code H is a feature designation common to both connectors, indicating a specific connector configuration within the SMB Fakra product family. This designation is maintained across both substitute parts.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions. Standard component storage practices apply.
