Part 0734040812 offers 1,396 pieces in stock. Operating temperature and mating cycle specifications are not provided for this part; engineering review is required if these parameters are critical to the application.

Part 0734036802 (main part) maintains 690 pieces in inventory and serves as the reference specification.

Frequently Asked Questions (FAQ)

Q: Can 0734035112 be used as a direct replacement for 0734036802?

A: Yes. Both parts share identical electrical specifications (50 Ohm impedance, 6 GHz maximum frequency, 335 V rating), mechanical configuration (SMB Fakra Jack, through-hole right-angle solder mount), and compliance status (ROHS3 Active). Variations in body material composition do not affect functional performance.

Q: What is the difference between 0734040812 and the main part?

A: The 0734040812 maintains electrical and mechanical compatibility. Operating temperature range and mating cycle specifications are not provided for this part. If these parameters are application-critical, the main part 0734036802 or substitute 0734035112 should be selected.

Q: Are all three parts suitable for 50 Ohm RF applications up to 6 GHz?

A: Yes. All three parts are rated for 50 Ohm impedance and 6 GHz maximum frequency operation.

Q: What is the significance of Code C in the Features field?

A: Code C is a Fakra connector coding designation that ensures mechanical and electrical compatibility between mating connectors. All three parts carry this designation.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in Tray packaging.

Q: Which part should be selected for new designs?

A: Any of the three parts meets the specified electrical and mechanical requirements. Selection should be based on inventory availability, lead time, and procurement strategy. Part 0734035112 offers the highest stock level.
