Substitute Part Grouping Explanation

Parametric equivalence for substitute diodes in the "Diodes, Rectifiers" category is determined exclusively by the following criteria:

Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io)
Voltage - Forward (Vf) (Max) @ If
Reverse Recovery Time (trr)
Current - Reverse Leakage @ Vr
Capacitance @ Vr, F
Speed Classification
Package / Case
Supplier Device Package
Mounting Type
Operating Temperature - Junction
Grade and Qualification (Automotive / AEC-Q101)
Compliance Status (RoHS3/REACH/MSL)

Only parts matching all the listed parameters qualify as parametric equivalents and substitutes.

Engineering Selection Recommendations

All listed substitute parts are active status products and RoHS3 compliant, with unlimited moisture sensitivity ratings (MSL 1) and REACH unaffected status. S2GHM3_A/I, S2GHE3_A/H, and S2GHE3_A/I are designated automotive grade and qualified to AEC-Q101. Selection among these substitutes should be based on required compliance criteria, especially for automotive or high-reliability environments. Supply chain and packaging requirements (Tape & Reel, Cut Tape, Digi-Reel®) are additional non-technical considerations.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to substitute a diode, rectifier part in this series?
A1: Voltage - DC Reverse (Vr), Current - Average Rectified (Io), Voltage - Forward (Vf) @ If, Reverse Recovery Time (trr), Current - Reverse Leakage @ Vr, Capacitance @ Vr and F, speed classification, mounting type, package/case, operating temperature range, grade, qualification, and compliance status must all match.

Q2: Is packaging a factor when selecting substitutes?
A2: Packaging type (Tape & Reel, Cut Tape, Digi-Reel®) does not affect electrical or mechanical compatibility but may be a consideration for manufacturing processes and inventory.

Q3: How important are grade and qualification for substitution?
A3: Grade and qualification (such as Automotive and AEC-Q101) are critical for use in automotive or stringent reliability applications. Substitute parts must carry the same qualification if the end-use requires it.

Q4: Are all parts listed mechanically and electrically identical?
A4: All parts listed match the key electrical, mechanical, and compliance parameters, enabling direct substitution within those constraints.

Q5: Does the supplier device package and mounting type affect compatibility?
A5: Yes, all substitutes must have the same supplier device package (DO-214AA, SMB) and support surface-mount mounting to be considered equivalent in form and fit.
