RGP10D-M3/54 Equivalent & Substitute Parts

Part Overview

The RGP10D-M3/54 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 1 A average rectified current in a DO-204AL (DO-41) through-hole axial package. This component is part of the SUPERECTIFIER® series and features fast recovery characteristics with a reverse recovery time of 150 ns.

The RGP10D-M3/54 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades. Substitute components must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating packaging and sourcing constraints.

Mandatory Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 1 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 150 ns
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A (maximum tolerance)

Mandatory Mechanical Parameters:

Mounting Type: Through Hole
Package / Case: DO-204AL (DO-41) Axial

Mandatory Environmental Parameters:

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Vishay SUPERECTIFIER® Series) Parts that maintain identical electrical specifications and are manufactured by the same supplier. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or product status (Active vs. Obsolete).

Category 2: Manufacturer-Recommended Alternatives Parts from alternative manufacturers that meet or exceed the electrical and mechanical requirements. These parts may exhibit variations in forward voltage, reverse recovery time, or capacitance characteristics while maintaining core voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can I use RGP10D-E3/54 as a direct replacement for RGP10D-M3/54?

A: Yes. RGP10D-E3/54 is a parametric equivalent with identical electrical specifications (200 V, 1 A, 1.3 V forward voltage, 150 ns reverse recovery time) and the same DO-204AL package. The primary difference is packaging format (Cut Tape vs. the original format). Both are ROHS3 compliant and rated for -65°C to 175°C operation.

Q: What is the difference between the Vishay SUPERECTIFIER® parts and the Taiwan Semiconductor Corporation 1N4935G?

A: The 1N4935G maintains the same voltage and current ratings (200 V, 1 A) and fast recovery characteristics. However, it exhibits a lower forward voltage (1.2 V vs. 1.3 V) and a longer reverse recovery time (200 ns vs. 150 ns). The operating temperature range is also narrower (-55°C to 150°C vs. -65°C to 175°C). These differences may affect circuit performance in temperature-sensitive or high-frequency switching applications.

Q: Is the EGP10D suitable for my application?

A: EGP10D meets the voltage and current requirements (200 V, 1 A) and is packaged in DO-204AL. However, it exhibits significantly different electrical characteristics: forward voltage is 0.95 V (lower), and reverse recovery time is 50 ns (faster). These characteristics make it suitable for applications where minimal forward voltage drop and fast switching are beneficial. Verify that your circuit design can accommodate these differences.

Q: Why is the 1N3611 not recommended?

A: The 1N3611 is rated for standard recovery characteristics (>500 ns), which does not meet the fast recovery requirement (≤500 ns) of the RGP10D-M3/54. Additionally, it is RoHS non-compliant. Use only if your application specifically requires standard recovery diodes and RoHS compliance is not a constraint.

Q: Can I use 1N5615 as a substitute?

A: No. Although 1N5615 maintains the 200 V voltage rating and fast recovery characteristics, it is rated for 2 A average rectified current, which exceeds the 1 A requirement of the RGP10D-M3/54. Additionally, its product status is discontinued at DiGi Electronics. It is not recommended for new designs or production runs.

Q: What packaging formats are available for Vishay SUPERECTIFIER® equivalents?

A: Vishay offers the following packaging formats for parametric equivalents:

Cut Tape (CT): RGP10D-E3/54, RGP10D-E3/73, 1N4942GP-E3/54
Tape & Reel (TR): RGP10DE-E3/54

Select the packaging format based on your procurement and assembly requirements. All formats maintain identical electrical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: No. Vishay SUPERECTIFIER® parts (RGP10D-E3/54, RGP10D-E3/73, RGP10DE-E3/54, 1N4942GP-E3/54) and Taiwan Semiconductor Corporation parts (1N4935G, 1N4935G A0G) are ROHS3 compliant. However, Microchip Technology parts (1N4942, 1N3611) and Semtech Corporation 1N5615 are either RoHS non-compliant or have unspecified RoHS status. Verify RoHS compliance requirements for your application before selecting a substitute.

Q: What is the difference between RGP10D-E3/54 and RGP10DE-E3/54?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is packaging format: RGP10D-E3/54 is supplied in Cut Tape (CT) format, while RGP10DE-E3/54 is supplied in Tape & Reel (TR) format. Select based on your assembly and procurement workflow.
