Equivalent & Substitute Parts Reference: DAP222MT2L

Part Overview

DAP222MT2L by Rohm Semiconductor is a diode array designed for general-purpose rectification, featuring a common anode configuration. It is classified under the Diodes, Rectifiers category and supplied in a SOT-723 surface-mount package. Key electrical parameters include an 80V DC reverse voltage, 100mA average rectified current per diode, 1.2V maximum forward voltage at 100mA, and 4ns reverse recovery time. DAP222MT2L is currently listed as obsolete, necessitating the identification of equivalent or substitute models to maintain design continuity in existing applications requiring matching electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on the provided electrical and mechanical parameters: diode configuration (1 pair common anode), maximum DC reverse voltage, average rectified current per diode, forward voltage, reverse recovery time, reverse leakage current, junction temperature rating, package type (surface mount), and compliance certifications (RoHS, REACH, MSL). Substitutes are grouped as parametric equivalents (identical key parameters and package) and similar parts (matching main function but varying voltage, current, or package).

Engineering Selection Recommendations

Selection should prioritize substitute parts with active status to ensure future availability. DAP222ZMT2L and MMBD1205 are active and meet RoHS3 and REACH compliance requirements, with MSL rated at 1 (Unlimited). DAP222ZMT2L retains identical electrical characteristics and packaging to DAP222MT2L, minimizing qualification effort for existing designs in SOT-723. MMBD1205 offers matching functional configuration but differs in electrical ratings and physical package. Both substitutes are suitable for applications requiring compliance with RoHS and REACH and ensuring uninterrupted production.

Frequently Asked Questions (FAQ)

Q1: What is the most direct replacement for DAP222MT2L in terms of parametric and mechanical compatibility?
A1: DAP222ZMT2L is an active model with identical electrical parameters and SOT-723 packaging.

Q2: Can MMBD1205 be used as a substitute for DAP222MT2L in SOT-723 designs?
A2: MMBD1205 matches the diode configuration but differs in package type and specific electrical ratings; suitability depends on package compatibility with the existing PCB footprint.

Q3: Are the substitute parts RoHS and REACH compliant?
A3: All referenced substitute parts are listed as ROHS3 compliant and REACH unaffected.

Q4: What criteria are used to select equivalent or substitute diode arrays?
