DAN202FMFHT106 Equivalent & Substitute Parts – Diodes, Rectifiers Reference

Part Overview

The DAN202FMFHT106, manufactured by Rohm Semiconductor, is a diode array featuring a 1 Pair Common Cathode configuration with 80 V maximum reverse voltage and 100 mA average rectified current per diode. This device is provided in a SC-70 (SOT-323) surface-mount package, is designed for small signal rectification, and includes AEC-Q101 automotive qualification and ROHS3 compliance. The product holds an active status. Engineering teams may require alternative models for supply chain flexibility, procurement objectives, or to maintain compliance with qualification and environmental standards.

Substitute Part Grouping Explanation

Substitute parts are selected strictly on the basis of matching the following key parameters: diode configuration (1 Pair Common Cathode), maximum reverse voltage (80 V), average rectified current per diode (100 mA), forward voltage at specified current (1.2 V @ 100 mA), reverse recovery time (4 ns), surface-mount package type (SC-70/SOT-323), and RoHS3/environmental status. Only parts fulfilling every explicitly provided parameter—including compliance and automotive qualification when indicated—are listed as valid substitutes.

Engineering Selection Recommendations

When selecting substitute parts for DAN202FMFHT106, only parts matching RoHS3 compliance and, where required, AEC-Q101 automotive qualification should be considered for applications where these certifications are mandated. Active product status is essential for ongoing designs. Note that 1SS301,LF does not specify AEC-Q101 qualification and has a lower maximum junction temperature. DAN202UT106 is not for new designs. For automotive or high-temperature environments, prioritize parts that match both the qualification and maximum junction temperature ratings as provided.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting an equivalent substitute for DAN202FMFHT106?
A1: Key substitution criteria include diode configuration, reverse voltage rating, average rectified current, forward voltage at specified current, reverse recovery time, package type, mounting method, environmental/RoHS compliance, and automotive qualification when required.

Q2: Are all packages and supplier device packages compatible?
A2: All listed substitutes use the SC-70, SOT-323 package or equivalent (UMD3, SC-70). Mechanical footprint and mounting compatibility should be verified strictly based on provided package specifications.

Q3: How important is AEC-Q101 qualification?
A3: AEC-Q101 qualification is mandatory for automotive-grade designs. Only parts explicitly marked with this qualification are suitable for such applications.

Q4: Is RoHS3 compliance maintained across all substitutes?
A4: All listed substitute parts provide ROHS3 compliance per supplied data.

Q5: Can substitute parts with lower maximum junction temperature be used?
A5: Application suitability depends on required operating temperature. Only use substitute parts with specified maximum junction temperature that meets or exceeds application requirements as provided.
