Frequently Asked Questions (FAQ)

Q: Can SE70PDHM3_A/H be used as a direct replacement for SE70PDHM3/86A?

A: Yes. SE70PDHM3_A/H is a direct substitute with identical electrical parameters (200 V, 2.9 A, 1.05 V forward voltage, 2.6 µs recovery time) and mechanical specifications (TO-277A SMPC package, surface mount). Both parts are AEC-Q101 qualified and RoHS3 compliant.

Q: What is the difference between SE70PD-M3/86A and SE70PD-M3/87A?

A: Both parts are parametric equivalents with identical electrical performance except for reverse recovery time. SE70PD-M3/86A specifies 2.6 µs trr, while SE70PD-M3/87A specifies 2.5 µs trr. This minor difference does not affect functional compatibility in standard rectification applications.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the TO-277A (SMPC) surface mount package with 3-PowerDFN case style. All are supplied in Tape & Reel (TR) packaging format, which is compatible with automated assembly processes.

Q: Do the substitute parts meet automotive qualification requirements?

A: SE70PDHM3_A/H and SE70PDHM3_A/I are both qualified to AEC-Q101 automotive standards. SE70PD-M3/86A and SE70PD-M3/87A do not list automotive grade or AEC-Q101 qualification in their specifications. For automotive applications requiring AEC-Q101 certification, use SE70PDHM3_A/H or SE70PDHM3_A/I.

Q: What is the moisture sensitivity level for these diodes?

A: All substitute parts carry MSL 1 (Unlimited) classification, indicating unlimited shelf life without moisture control requirements during storage and handling.

Q: Are these parts RoHS and REACH compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Which substitute part has the highest inventory availability?

A: SE70PD-M3/86A has the highest inventory with 1041 units in stock, followed by SE70PD-M3/87A with 840 units and SE70PDHM3_A/I with 747 units.
