Parameter Comparison

Engineering Selection Recommendations

The CDBP00340-HF serves as the direct functional equivalent to the obsolete CDBP00340. Selection of the CDBP00340-HF is supported by the following factors:

All electrical parameters are identical across both parts, including reverse voltage rating, forward voltage drop, reverse leakage current, and junction capacitance. Both components maintain the same SOD-723 surface mount package geometry and pinout, ensuring mechanical compatibility in existing PCB layouts without design modification.

The CDBP00340-HF carries active product status from Comchip Technology, providing assured long-term availability and manufacturing continuity. Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and moisture sensitivity requirements.

The primary distinction is packaging format: the CDBP00340-HF is supplied in Tape & Reel format, which is the standard distribution method for high-volume surface mount component procurement.

Frequently Asked Questions (FAQ)

Q: Can the CDBP00340-HF be used as a direct replacement for the CDBP00340?
