Substitute Part Grouping Explanation

Substitute parts for BAT54SHMFHT116 are identified based on category (Diodes, Rectifiers), diode technology (Schottky), electrical configuration (1 Pair Series Connection), maximum reverse voltage (30 V), maximum average forward current (200 mA per diode), forward voltage characteristics, reverse recovery time, reverse leakage current, surface mount packaging (TO-236-3, SC-59, SOT-23-3), AEC-Q101 qualification (automotive grade when applicable), and regulatory compliance (ROHS3, REACH). Only models matching these critical parameters are considered equivalent or substitutable.

Engineering Selection Recommendations

All substitute parts listed are active status and ROHS3 compliant with MSL rating of “1 (Unlimited)” and “REACH Unaffected” status. AEC-Q101 automotive qualification is present for Rohm Semiconductor BAT54SHMFHT116, BAT54SHMT116, BAT54SHYFHT116, and BAT54SHYT116. Cross-manufacturer alternatives BAT54SLT1G and BAT54S_R1_00001 provide similar electrical and mechanical characteristics but do not list AEC-Q101 qualification.

Frequently Asked Questions (FAQ)

Q1: What parameters determine substitution for BAT54SHMFHT116 diodes?
A1: Substitute selections require matching diode configuration, technology (Schottky), maximum DC reverse voltage (30 V), average rectified current per diode (200 mA), forward voltage rating, reverse leakage, package type, mounting method, and relevant qualifications such as AEC-Q101 where required.

Q2: Do all substitutes have the same package as BAT54SHMFHT116?
A2: All listed substitute and similar parts are in TO-236-3, SC-59, or SOT-23-3 surface mount packages, ensuring mechanical compatibility.

Q3: What is the importance of AEC-Q101 qualification in substitute selection?
A3: AEC-Q101 qualification ensures automotive-grade reliability and is necessary for designs requiring automotive compliance. Only BAT54SHMFHT116, BAT54SHMT116, BAT54SHYFHT116, and BAT54SHYT116 provide AEC-Q101 qualification.

Q4: Are there differences in operating temperature among substitutes?
A4: BAT54SHMFHT116 and Rohm equivalents are rated up to 150°C, while BAT54SLT1G and BAT54S_R1_00001 specify a maximum of 125°C.

Q5: Does the forward voltage differ between substitutes?
A5: All Rohm and onsemi alternatives specify 800 mV @ 100 mA; BAT54S_R1_00001 specifies 600 mV @ 100 mA.

Q6: Are regulatory compliance and MSL the same among substitutes?
A6: All substitutes are ROHS3 compliant, MSL 1 (Unlimited), and REACH Unaffected according to provided input.
