Equivalent & Substitute Parts Reference: FMB-29L

Part Overview

The Sanken Electric USA Inc. FMB-29L is a Diode Array Schottky, housed in a TO-220-3 Full Pack package. It features a 1 Pair Common Cathode configuration, designed for fast recovery applications with a maximum reverse voltage of 90 V and a rectified current of 8A per diode. The product status is listed as Obsolete. When a component is discontinued, identifying compatible substitutes with matching electrical ratings and package types is required to maintain system continuity and facilitate ongoing maintenance or production.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the FMB-29L is determined exclusively by matching the following key parameters: diode configuration (1 Pair Common Cathode), technology type (Schottky), maximum DC reverse voltage (Vr), average rectified current per diode (Io), forward voltage (Vf) at specified current, recovery speed, reverse leakage current, operating temperature range, mounting type, package/case type (TO-220-3 Full Pack), RoHS compliance, and moisture sensitivity level. Only substitutes whose specifications align with these criteria are presented.

Parameter Comparison

Engineering Selection Recommendations

The FMB-29L is designated as obsolete; therefore, selection should be limited to substitute parts with active product status and comparable compliance certifications. Substitute components RB085T-60 and SRF1090 C0G are both listed as active products, possess RoHS3 compliance, and an MSL of 1 (Unlimited), aligning with the original part's environmental and handling certifications.

Frequently Asked Questions (FAQ)

Q1: What are the critical electrical parameters for substituting FMB-29L?
A1: The essential electrical substitution parameters are diode configuration (1 Pair Common Cathode), Schottky technology, DC reverse voltage (Vr), average rectified current (Io), forward voltage (Vf) at specified current, recovery speed, and reverse leakage current.

Q2: Are the substitute parts compatible in terms of mounting and package type?
A2: All listed substitutes feature Through Hole mounting and TO-220-3 Full Pack package compatibility. The SRF1090 C0G variant additionally includes an isolated tab, which may provide supplementary mounting isolation properties.

Q3: What environmental criteria must substitute parts meet?
A3: Substitute components must possess equivalent RoHS compliance and moisture sensitivity level (MSL 1, Unlimited), ensuring storage and handling congruency with the FMB-29L.

Q4: How does the product status affect part selection?
A4: Only active substitute parts are considered suitable, consistent with procurement and inventory continuity following the FMB-29L's obsolete status. Active status ensures ongoing manufacturer support and availability.

Q5: How should forward voltage and reverse leakage values be considered?
A5: Substitute parts present distinct forward voltage and reverse leakage values within the Schottky diode category. Only values cited in the provided parameters are considered during substitution.
