DAP202UMTL Equivalent & Substitute Parts Reference, Diodes, Rectifiers

Part Overview

DAP202UMTL from Rohm Semiconductor is a diode array with a 1 pair common anode configuration, rated at 80 V reverse voltage and 100 mA average rectified current per diode. Offered in surface mount SC-85 (UMD3F), it is suited for general purpose rectification and signal routing in compact circuits. Currently in active production with substantial inventory available. Evaluating alternative models is necessary for risk mitigation, supply chain continuity, and ensuring compatibility in case of product status change, allocation, or design migration.

Substitute Part Grouping Explanation

Substitution is determined strictly by electrical and mounting parameters, including diode configuration, reverse voltage, average rectified current, forward voltage, reverse recovery time, leakage current, maximum junction temperature, surface mount packaging, and compliance status. All parts listed feature 1 pair common anode configuration, 80 V reverse voltage rating, similar or higher current capability, compatible forward voltage, comparable reverse recovery, surface mount packages, and relevant compliance (RoHS, REACH, ECCN). Product status and automotive qualification are also presented for engineering risk analysis per supplied parameters.

Engineering Selection Recommendations

DAP202UMTL (Active) is suitable for ongoing and new designs. DAP202UMFHTL is not for new designs and includes automotive grade and AEC-Q101 qualification. 1PS300,115 is active and automotive qualified. All substitutes are RoHS3 compliant, REACH unaffected, and have MSL 1 (unlimited) rating. Selection should be based on product status, required automotive qualifications, and package compatibility as per specified parameters.

Frequently Asked Questions (FAQ)

Q: Which key electrical parameters must match for acceptable substitution?
A: Diode configuration, maximum reverse voltage (Vr), average rectified current (Io), forward voltage (Vf), reverse recovery time (trr), reverse leakage current, and maximum junction temperature must match or meet application requirements.

Q: Are all substitute diodes compatible in terms of mounting and package?
A: Substitute parts utilize surface mount packages; specifically, DAP202UMTL and DAP202UMFHTL use SC-85 (UMD3F), while 1PS300,115 uses SC-70, SOT-323. Ensure PCB layout is designed for the selected package.

Q: What compliance levels are maintained across all options?
A: All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: Can automotive grade or AEC-Q101 qualification be a selection criterion?
A: DAP202UMFHTL and 1PS300,115 include automotive grade and AEC-Q101 qualification; DAP202UMTL does not specify these grades.

Q: Is product status important for long-term design support?
A: Active status indicates support for new and ongoing designs; “Not For New Designs” status may limit future availability.

Q: How does reverse leakage current differ among substitutes?
A: DAP202UMTL and DAP202UMFHTL specify 100 nA @ 70 V; 1PS300,115 specifies 500 nA @ 80 V. Confirm suitability per application.
