Equivalent & Substitute Parts Reference for FML-12S

Part Overview

The FML-12S, manufactured by Sanken Electric USA Inc., is an obsolete diode array product in the Diodes, Rectifiers category. It features a 1 Pair Common Cathode configuration, a 200 V maximum reverse voltage, 5A average rectified current per diode, and a TO-220-3 Full Pack package suitable for through-hole mounting. As the FML-12S is marked as obsolete, sourcing alternative models with strictly equivalent electrical, mechanical, and compliance parameters is required for continued product support and drop-in replacement in legacy designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution grouping is performed strictly according to the following key parameters: diode configuration (1 Pair Common Cathode), voltage rating (200 V), similar or higher speed (≤500ns), mounting type (Through Hole), and compatible package/case (TO-220-3 Full Pack). Compliance requirements are matched on RoHS status and MSL rating. Parameters that may influence fit or function, such as average rectified current and reverse recovery time, are compared to ensure equivalent or safely derated operation.

Engineering Selection Recommendations

The FML-12S is obsolete. Substitute selection within the Diodes, Rectifiers product category must prioritize active status and strict matching of compliance certifications, including RoHS and MSL level. The RF601T2D from Rohm Semiconductor is active, ROHS3 compliant, and has an MSL rating of 1 (Unlimited), consistent with FML-12S compliance data. Both share the same ECCN and HTSUS codes, supporting regulatory equivalence.

Frequently Asked Questions (FAQ)

Q1: What are the core parameters necessary for substituting FML-12S in a design?
A1: Core parameters include diode configuration (1 Pair Common Cathode), maximum DC reverse voltage (200 V), rectified current rating, forward voltage, speed (reverse recovery time), mounting type, and package/case compatibility.

Q2: Does the RF601T2D have the same package footprint as FML-12S?
A2: Both FML-12S and RF601T2D use the TO-220-3 Full Pack package, suitable for through-hole mounting.

Q3: Is there any difference in compliance or certification status between FML-12S and the substitute?
A3: Both parts meet RoHS compliance and have a moisture sensitivity level (MSL) of 1 (Unlimited). They share the same ECCN (EAR99) and HTSUS classification.

Q4: Are there differences in electrical ratings to consider?
A4: The FML-12S is rated at 5A per diode, while the RF601T2D is rated at 3A per diode. Reverse voltage and speed parameters are equivalent.

Q5: Can the substitute be used in the same operating temperature range?
A5: Both parts share a maximum operating junction temperature of 150°C; the FML-12S lists a range starting from -40°C, while the RF601T2D lists only the maximum.

Q6: Are the supplier device package codes for the substitute and original part interchangeable?
A6: FML-12S specifies TO-220F-3 and RF601T2D specifies TO-220FN; these refer to mechanically equivalent packages within the TO-220-3 Full Pack family for through-hole mounting.
