RGP10K Equivalent & Substitute Parts

Part Overview

The RGP10K is a general-purpose rectifier diode manufactured by onsemi, rated for 800 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 This component is classified as "Not For New Designs," indicating it has been superseded in onsemi's product portfolio. Equivalent and substitute parts are necessary for applications requiring continued sourcing, design flexibility, or alternative supplier options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the RGP10K are classified into two categories based on electrical parameter alignment:

Direct Equivalents (Identical Electrical Specifications): Parts that match all critical electrical parameters: 800 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, 500 ns reverse recovery time, and 5 µA reverse leakage current at 800 V. These parts maintain fast recovery characteristics and are suitable for direct replacement in existing designs.

Similar Alternatives (Acceptable Parameter Variations): Parts that meet the core voltage and current ratings but differ in secondary characteristics such as forward voltage drop, reverse recovery time, reverse leakage current, or capacitance. These parts are electrically compatible for applications where the specific performance differences do not impact circuit operation. Differences include standard recovery characteristics (>500 ns) versus fast recovery (≤500 ns), lower reverse leakage (1 µA versus 5 µA), and reduced capacitance values.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): 800 V minimum
Current - Average Rectified (Io): 1 A
Mounting Type: Through Hole
Package / Case: DO-204AL (DO-41) or equivalent axial package
Operating Temperature Range: -65°C to 150°C minimum
RoHS Compliance: ROHS3 Compliant

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

The parts BA159DGP-E3/54, RGP10K-E3/54, and RGP10KE-E3/54 from Vishay General Semiconductor are direct electrical equivalents to the RGP10K. All three maintain 800 V reverse voltage, 1 A current rating, 1.3 V forward voltage drop at 1 A, and 500 ns reverse recovery time. These parts are classified as Active products and are ROHS3 compliant. Selection among these three should be based on packaging format: BA159DGP-E3/54 is supplied in Tape & Reel (TR) format with 1129 pieces in stock; RGP10K-E3/54 is supplied in Tape & Reel format with 1102 pieces in stock; RGP10KE-E3/54 is supplied in Tape & Reel format with 959 pieces in stock.

Compatible Alternatives (Acceptable Variations):

The 1N4248GP-E3/54 and 1N4248GP-E3/73 from Vishay offer lower forward voltage drop (1.2 V versus 1.3 V) and reduced reverse leakage current (1 µA versus 5 µA), with standard recovery characteristics. These parts are suitable for applications where lower forward voltage drop is beneficial. Operating temperature range is -65°C to 160°C, which is 15°C lower than the RGP10K maximum.

The GP10K-E3/54 and GP10K-E3/73 from Vishay maintain 800 V and 1 A ratings with 1.2 V forward voltage drop but feature longer reverse recovery time (3 µs versus 500 ns). These parts are suitable for applications where fast recovery is not critical.

The GP10M-E3/54 from Vishay provides higher voltage rating (1000 V versus 800 V) with 1 A current and 1.2 V forward voltage drop. This part is suitable for applications requiring higher voltage margin.

Package Considerations:

The D6G-T and D7G-T from Diodes Incorporated use T-1 package format instead of DO-41. These parts are not mechanically interchangeable with the RGP10K without board redesign or adapter solutions. D6G-T maintains 800 V rating; D7G-T provides 1000 V rating. Both feature standard recovery characteristics (2 µs) and lower forward voltage drop (1.0 V).

All substitute parts are ROHS3 compliant and REACH unaffected, matching the RGP10K compliance status.

Frequently Asked Questions (FAQ)

Q: Can I use BA159DGP-E3/54 as a direct replacement for RGP10K?

A: Yes. BA159DGP-E3/54 is a direct electrical equivalent with identical voltage rating (800 V), current rating (1 A), forward voltage drop (1.3 V @ 1 A), and reverse recovery time (500 ns). Both are through-hole axial packages in DO-41 format. The primary difference is packaging format: BA159DGP-E3/54 is supplied in Tape & Reel while RGP10K is supplied in Cut Tape.

Q: What is the difference between fast recovery (500 ns) and standard recovery (>500 ns) diodes?

A: Fast recovery diodes have reverse recovery time of 500 ns or less, reducing switching losses in high-frequency applications. Standard recovery diodes have reverse recovery time greater than 500 ns. For low-frequency rectification applications, standard recovery diodes are acceptable. The choice depends on circuit operating frequency and switching characteristics.

Q: Can I substitute RGP10K with D6G-T?

A: D6G-T is electrically compatible (800 V, 1 A) but uses T-1 package instead of DO-41. Direct board substitution is not possible without mechanical redesign. D6G-T features lower forward voltage drop (1.0 V versus 1.3 V) and standard recovery characteristics (2 µs versus 500 ns).

Q: Why does 1N4248GP-E3/54 have lower reverse leakage current (1 µA versus 5 µA)?

A: Reverse leakage current varies based on semiconductor manufacturing process and device design. Lower leakage current indicates better reverse blocking characteristics. For most applications, this difference is not significant. Selection should be based on circuit requirements for leakage current at operating temperature.

Q: Is GP10M-E3/54 a suitable replacement for RGP10K?

A: GP10M-E3/54 is electrically compatible with higher voltage rating (1000 V versus 800 V) and identical current rating (1 A). It is suitable for applications where higher voltage margin is required. The 1000 V rating provides additional safety margin in circuits designed for 800 V operation.

Q: What does "Not For New Designs" mean for RGP10K?

A: "Not For New Designs" indicates that onsemi has discontinued active development and promotion of this part. New circuit designs should use active alternatives such as BA159DGP-E3/54, RGP10K-E3/54, or RGP10KE-E3/54. Existing designs using RGP10K can continue with equivalent parts from active product lines.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the RGP10K compliance status. This ensures compatibility with environmental and regulatory requirements.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies components on tape that is cut into individual strips, typically for lower-volume applications. Tape & Reel packaging supplies components on continuous tape wound on reels, typically for higher-volume automated assembly. Electrical specifications are identical; packaging format affects handling and assembly processes.
