Frequently Asked Questions (FAQ)

Q: Can SF62G or SF62GH be used as direct replacements for SF62G-TP in existing designs?

A: Yes. Both substitute parts meet all critical electrical parameters: 100 V reverse voltage, 6 A average rectified current, 975 mV forward voltage drop at 6 A, 35 ns reverse recovery time, and identical thermal operating range (-55°C to 150°C). The DO-201AD axial through-hole package is identical, enabling direct board-level substitution.

Q: What is the difference between SF62G and SF62GH?

A: The SF62G and SF62GH are electrically identical. The SF62GH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. Both parts have identical electrical specifications and package configurations. Selection between them depends on application requirements and qualification mandates.

Q: Does the capacitance difference between SF62G-TP (120 pF) and the substitutes (100 pF) affect circuit performance?

A: The capacitance variation (120 pF versus 100 pF at 4 V, 1 MHz) does not affect functional equivalence for standard rectification applications. This parameter variation is within acceptable tolerances for general-purpose rectifier diodes and does not impact switching characteristics or reverse recovery behavior.

Q: Are all substitute parts RoHS compliant?

A: Yes. SF62G and SF62GH are both ROHS3 compliant, matching the compliance status of the SF62G-TP. All parts carry REACH Unaffected status and are classified under ECCN EAR99.

Q: What is the inventory status of substitute parts?

A: SF62G has 659 pieces in stock, and SF62GH has 660 pieces in stock. Both substitute parts are available as new original components in tape and reel packaging.
