DA221MT2L Equivalent & Substitute Parts Reference

Part Overview

The DA221MT2L by Rohm Semiconductor is a surface mount diode array configured as 1 pair in series connection, with a maximum reverse voltage of 20 V and an average rectified current per diode of 100 mA. It is housed in a SOT-723 (VMD3) package. The product is classified as obsolete. Sourcing alternatives is essential to maintain design continuity and component availability. Alternative models must meet or exceed the specified electrical, mechanical, compliance, and package-related parameters.

Engineering Selection Recommendations

The DA221MT2L is obsolete. DA221ZMT2L is a parametric equivalent from the same manufacturer with matching electrical, mechanical, and compliance attributes and is active in production. BAV199,215 from Nexperia USA Inc. aligns in key parameters for diode configuration, mounting, and compliance. All listed substitutes are ROHS3 compliant, REACH unaffected, and share MSL rating 1. Substitute selection may be governed by current product status and required compliance documentation.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when substituting DA221MT2L with another diode array?
A1: Key parameters include diode configuration, maximum DC reverse voltage, average rectified current, forward voltage at a specified current, reverse leakage, speed class, operating temperature, mounting type, package, RoHS and REACH statuses, and MSL rating.

Q2: Does DA221MT2L have a direct parametric equivalent?
A2: Yes. DA221ZMT2L from Rohm Semiconductor matches all specified parameters and is in active production.

Q3: Is the package type critical when selecting a substitute?
A3: Yes. The mounting type and package/case (e.g., SOT-723) must conform to the original design to ensure mechanical and assembly compatibility.

Q4: Are the listed substitutes compliant with RoHS3 and REACH?
A4: All listed substitutes, including DA221ZMT2L and BAV199,215, are specified as ROHS3 compliant and REACH unaffected.

Q5: Can higher voltage or current ratings be used as substitutes?
A5: Substitutes with equal or higher voltage and current specifications are acceptable if all other parameters match, as listed in the table.

Q6: What is the significance of product status in selecting a substitute?
A6: Active production status ensures continued supply and availability, as DA221MT2L is obsolete.
