Equivalent & Substitute Parts Reference for FMB-2204

Part Overview

The Sanken Electric USA Inc. FMB-2204 is an obsolete diode array, Schottky type, part of the Diodes, Rectifiers category. It features a 1 Pair Common Cathode configuration, rated for 40 V reverse voltage and 20A average rectified current per diode, with fast recovery and through-hole TO-220-3 Full Pack packaging. Due to its obsolete status and inventory constraints, sourcing alternative or equivalent models is necessary for ongoing production, maintenance, and repair requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the FMB-2204 relies strictly on the following parameters: diode configuration (1 Pair Common Cathode), maximum DC reverse voltage (40 V), average rectified current per diode (20A or similar), voltage forward maximum at specified current (550 mV @ 10 A), Schottky technology, mounting type (Through Hole), package compatibility (TO-220-3 Full Pack or TO-220FN), product status, and compliance with RoHS and MSL standards. Only parts matching or closely aligning with these specifications are included in the substitute list.

Parameter Comparison

Engineering Selection Recommendations

For replacing the obsolete FMB-2204, select only substitute diode parts that meet the specified compliance criteria (RoHS, MSL levels) and offer equivalent packaging and electrical ratings according to provided data. The FMW-2204 is parametric equivalent, matching electrical and package parameters precisely. The RB215T-40 offers similar configuration and voltage ratings, but with a reduced average rectified current per diode (10A vs. 20A), and remains active in production.

Frequently Asked Questions (FAQ)

Q1: What are the necessary parameters for substituting FMB-2204?
A1: Substitute parts must match diode configuration, maximum DC reverse voltage, average rectified current per diode, voltage-forward characteristics, technology (Schottky), mounting type, and package.

Q2: Are substitutes required to have identical package types?
A2: Substitute package must be TO-220-3 Full Pack or a package noted as compatible by the manufacturer for this category.

Q3: Can RB215T-40 be used directly in FMB-2204 applications?
A3: RB215T-40 matches diode configuration, voltage, technology, and package but offers 10A average rectified current per diode versus 20A. Usage is determined strictly by current requirements of the specific application.

Q4: Is RoHS status important for substitution?
A4: Substitute parts must match or exceed RoHS compliance level specified for the target application.

Q5: Why is FMW-2204 considered a parametric equivalent?
A5: FMW-2204 matches all critical electrical and mechanical parameters specified for FMB-2204.
