RS1FLD-M3/I Equivalent & Substitute Parts

Part Overview

The RS1FLD-M3/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode is rated for 200 V DC reverse voltage with 1 A average rectified current and is packaged in the DO-219AB (SMF) form factor. The device is currently in active production status with 729 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs. Substitutes must maintain identical or superior ratings across all critical electrical parameters and share the same package specification.

Substitute Part Grouping Explanation

Substitution eligibility for the RS1FLD-M3/I is determined by strict equivalence across the following critical parameters:

Reverse Voltage Rating (Vr): Must equal 200 V maximum
Average Rectified Current (Io): Must equal 1 A
Forward Voltage (Vf): Must not exceed 1.2 V at 1 A
Reverse Recovery Time (trr): Must not exceed 500 ns
Reverse Leakage Current: Must not exceed 5 µA at 200 V
Package Specification: Must be DO-219AB (SMF) surface mount
Mounting Type: Must be surface mount compatible
Operating Temperature Range: Must support -55°C to 150°C junction temperature
Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The RS1FLD-M3/H meets all substitution criteria and is classified as a parametric equivalent.

Frequently Asked Questions (FAQ)

Q: Can the RS1FLD-M3/H be used as a direct replacement for the RS1FLD-M3/I?

A: Yes. The RS1FLD-M3/H is a parametric equivalent with identical electrical ratings, forward voltage characteristics, reverse recovery time, leakage current, and package specification. Direct substitution is supported without circuit modification.

Q: Are there any differences in the DO-219AB package between these two parts?

A: No. Both parts use the identical DO-219AB (SMF) surface mount package. PCB footprint, solder pad configuration, and mechanical dimensions are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RS1FLD-M3/I and RS1FLD-M3/H are ROHS3 compliant and REACH unaffected. Both carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the difference between the RS1FLD-M3/I and RS1FLD-M3/H designations?

A: The suffix designations (I and H) indicate different packaging or tape reel configurations from Vishay. Both parts are electrically and mechanically identical. The designation difference does not affect electrical performance or substitution compatibility.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across the identical junction temperature range of -55°C to 150°C.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical electrical specifications and package designations, they can be used interchangeably in the same circuit design and production environment.
