Engineering Selection Recommendations

All listed substitute parts are active and ROHS3 compliant. When automotive qualification (AEC-Q101) is required, select only models with explicit certification such as BAS40-05HYFHT116 and BAS40-05HYT116. For applications not requiring AEC-Q101 or automotive grade, selection can be based on package type and inventory availability as all substitutes maintain required safety, compliance, and electrical ratings.

Frequently Asked Questions (FAQ)

Q1: What are the criteria for substituting BAS40-05HMFHT116 in an assembly?
A1: Substitution requires matching diode configuration, Schottky technology, maximum reverse voltage, average rectified current per diode, forward voltage at specified current, reverse leakage current, operating temperature, mounting type, and package specifications. Compliance and qualification must be maintained for regulated applications.

Q2: Are package variants interchangeable among substitute part numbers?
A2: All listed substitute parts are compatible with surface mount technology and available in TO-236-3, SC-59, and SOT-23-3 package formats, ensuring direct interchangeability on PCBs designed for these cases.

Q3: How does automotive qualification (AEC-Q101) affect substitute selection?
A3: For automotive-grade assemblies, only substitutes explicitly qualified to AEC-Q101 are suitable. This includes BAS40-05HYFHT116 and BAS40-05HYT116.

Q4: Will substituting a part with higher average rectified current create compatibility issues?
A4: Substitute parts with ≥120mA rating are electrically compatible provided all other parameters are matched. Substitute parts with a higher current rating may offer additional headroom without compromising performance.

Q5: Are there differences in RoHS or REACH compliance among substitutes?
A5: All listed substitutes are ROHS3 compliant and REACH unaffected, confirming regulatory compatibility for global applications.
