Substitute Part Grouping Explanation

Substitute or equivalent diodes for the RB088BM-40TL are selected strictly based on the following parameters: identical diode configuration (1 pair common cathode), technology (Schottky), maximum reverse voltage (40 V), average rectified current rating (10A per diode), forward voltage drop (770 mV @ 5 A), reverse leakage current (3 µA @ 40 V), fast recovery speed (≤ 500 ns), junction temperature (150°C), and mechanical compatibility with the TO-252-3, DPAK (2 Leads + Tab), SC-63 surface-mount package. All substitutes listed conform to regulatory standards (RoHS3, REACH), have the same MSL, and share identical compliance designators.

Parameter Comparison

Engineering Selection Recommendations

Selection between RB088BM-40TL and RB088BM-40FHTL is based on product status, compliance certifications, and package compatibility. Both parts are active, ROHS3 compliant, REACH unaffected, have MSL 1 (unlimited), and identical mechanical footprint. Qualification for automotive standards (AEC-Q101) is an additional attribute for RB088BM-40FHTL but does not impact general substitutability based on provided parameters.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting RB088BM-40TL in an application?
A1: The substitute part must match the diode configuration, technology, voltage and current ratings, forward voltage drop, reverse leakage, speed, operating temperature, mounting type, and package, as well as meet the same regulatory compliance and mechanical standards.

Q2: Are RB088BM-40TL and RB088BM-40FHTL interchangeable without PCB modifications?
A2: Both parts are provided in the TO-252-3, DPAK (2 Leads + Tab), SC-63 surface-mount package and share identical mechanical dimensions, enabling direct interchangeability on compatible PCBs.

Q3: Do compliance and qualification differences affect substitution?
A3: Both parts are ROHS3 compliant and REACH unaffected. RB088BM-40FHTL includes automotive AEC-Q101 qualification, but this does not restrict its substitutability for general applications based solely on the provided parameters.

Q4: Is there any impact on moisture sensitivity when substituting these parts?
A4: Both RB088BM-40TL and RB088BM-40FHTL have a moisture sensitivity level (MSL) of 1 (unlimited), so there is no difference in handling or storage requirements.

Q5: Can supply format (Tape & Reel, Cut Tape, Digi-Reel®) affect interchangeability?
A5: Supply format differences are not relevant to electrical or mechanical compatibility, provided the mounting and package remain consistent.
