RGP10G Equivalent & Substitute Parts

Part Overview

The RGP10G is a general-purpose rectifier diode manufactured by onsemi, rated for 400 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole package. This component is classified as "Not For New Designs," indicating it is an established product suitable for maintenance, repair, and legacy system applications. The fast recovery characteristic (≤500 ns for currents >200 mA) makes it suitable for switching power supplies and similar applications requiring rapid diode switching.

Equivalent and substitute parts are necessary for design flexibility, supply chain continuity, and sourcing alternatives when the primary part becomes unavailable or when different packaging or performance characteristics are required for specific applications.

Substitute parts for the RGP10G are grouped based on strict electrical and mechanical compatibility criteria. All substitute parts must meet or exceed the following key parameters:

Electrical Compatibility Requirements:

Voltage - DC Reverse (Vr) (Max): 400 V minimum
Current - Average Rectified (Io): 1 A minimum
Speed: Fast Recovery ≤500 ns for currents >200 mA
Current - Reverse Leakage @ Vr: 5 µA @ 400 V maximum
Operating Temperature - Junction: Must accommodate the application's thermal requirements

Mechanical Compatibility Requirements:

Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, or Axial configurations
Supplier Device Package: Must be compatible with existing PCB layouts

Substitute parts are classified into two categories:

Direct Equivalents: Parts with identical electrical specifications and forward voltage characteristics (Vf = 1.3 V @ 1 A), including RGP10G-E3/54 and RGP10GE-E3/54 from Vishay General Semiconductor - Diodes Division, and BYD33GGPHE3/54 from the same manufacturer.

Functional Equivalents: Parts meeting all electrical requirements but with minor variations in reverse recovery time, forward voltage, or capacitance, including 1N4936-E3/54, 1N4936-T, 1N4936G-T, 1N4936G, 1N4936GP-AP, and 1N4936GP-BP. These parts maintain the 400 V / 1 A rating and fast recovery characteristic while offering alternative sourcing options.

Engineering Selection Recommendations

Direct Substitution (Identical Electrical Performance):

RGP10G-E3/54 and RGP10GE-E3/54 from Vishay General Semiconductor - Diodes Division are direct substitutes with identical electrical specifications. Both parts are Active status products, providing long-term availability assurance. BYD33GGPHE3/54 also matches all electrical parameters and is Active status. These three parts are preferred for new procurement when the RGP10G becomes unavailable, as they maintain the 1.3 V forward voltage and 150 ns reverse recovery time of the original design.

Functional Substitution (Compatible Electrical Performance):

The 1N4936 series parts (1N4936-E3/54, 1N4936-T, 1N4936G-T, 1N4936G, 1N4936GP-AP, 1N4936GP-BP) are functionally equivalent with slightly different electrical characteristics. These parts feature 1.2 V forward voltage (0.1 V lower than RGP10G) and 200 ns reverse recovery time (50 ns longer than RGP10G). All maintain the 400 V / 1 A rating and fast recovery characteristic. These parts are suitable for applications where the minor forward voltage and recovery time differences do not impact circuit performance. All 1N4936 variants are Active status products except where noted.

Axial Package Alternative:

1N4936RLG from onsemi provides an axial package configuration while maintaining 400 V / 1 A electrical ratings. This part is suitable for applications requiring axial lead orientation. The 300 ns reverse recovery time is longer than the original RGP10G but remains within fast recovery classification.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the RGP10G. Moisture Sensitivity Level (MSL) varies between parts; applications requiring specific MSL ratings should verify compatibility with storage and handling requirements.

Temperature Range Considerations:

RGP10G and RGP10G-E3/54 support the widest junction temperature range (-65°C to 175°C). Applications requiring operation above 150°C should prioritize these parts. For applications limited to -50°C to 150°C or -55°C to 150°C ranges, the 1N4936 series variants are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use 1N4936-E3/54 as a direct replacement for RGP10G?

A: 1N4936-E3/54 is a functional equivalent meeting all electrical requirements (400 V, 1 A, fast recovery). The forward voltage is 1.2 V versus 1.3 V for RGP10G, and reverse recovery time is 200 ns versus 150 ns. These differences are acceptable in most applications. However, if your circuit design depends on the specific 1.3 V forward voltage or 150 ns recovery time, use RGP10G-E3/54 or RGP10GE-E3/54 instead for identical performance.

Q: What is the difference between RGP10G-E3/54 and RGP10GE-E3/54?

A: Both parts are manufactured by Vishay General Semiconductor - Diodes Division and have identical electrical specifications (400 V, 1 A, 1.3 V Vf, 150 ns trr). Both are Active status products in DO-204AL (DO-41) package. The parts are interchangeable for all practical applications.

Q: Why does RGP10G have "Not For New Designs" status while RGP10G-E3/54 is Active?

A: RGP10G is an older part number designation that has been superseded by RGP10G-E3/54 and RGP10GE-E3/54. The "Not For New Designs" status indicates the original part number is no longer recommended for new circuit designs. However, RGP10G-E3/54 and RGP10GE-E3/54 are the current Active equivalents with identical performance and should be used for new designs requiring this electrical specification.

Q: Can I use the axial package 1N4936RLG instead of the DO-41 package RGP10G?

A: 1N4936RLG meets all electrical requirements (400 V, 1 A, fast recovery) but has a different physical package (axial leads instead of DO-41 radial leads). Substitution is only possible if your PCB layout accommodates axial lead spacing and orientation. The 300 ns reverse recovery time is longer than RGP10G's 150 ns but remains within fast recovery specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant, matching the environmental compliance of RGP10G. All parts are also REACH unaffected.

Q: What is the significance of the forward voltage difference between RGP10G (1.3 V) and 1N4936 variants (1.2 V)?

A: The 0.1 V difference in forward voltage affects power dissipation and voltage drop across the diode during conduction. In low-current applications or designs with tight voltage budgets, this difference may be significant. For most general-purpose rectification applications, the difference is negligible. Verify circuit performance if forward voltage is a critical design parameter.

Q: Which substitute part offers the best long-term availability?

A: RGP10G-E3/54, RGP10GE-E3/54, and BYD33GGPHE3/54 are all Active status products from established manufacturers (Vishay General Semiconductor - Diodes Division). The 1N4936 series variants from Diodes Incorporated, Taiwan Semiconductor Corporation, and Micro Commercial Co are also Active status. All provide reliable long-term sourcing compared to the "Not For New Designs" RGP10G.

Q: Can I mix different substitute parts in the same circuit?

A: Yes, all listed substitute parts are electrically compatible and can be used interchangeably within the same circuit. However, for consistency in manufacturing and testing, it is recommended to standardize on a single part number per design.

Q: What packaging options are available for substitutes?

A: Most substitutes are available in DO-204AL (DO-41) package, which is compatible with RGP10G's DO-41 package. 1N4936RLG is available in axial package configuration. Verify the specific supplier device package when ordering to ensure PCB compatibility.
