RGP10A Equivalent & Substitute Parts

Part Overview

The RGP10A is a general-purpose fast recovery rectifier diode manufactured by onsemi, rated for 50 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 This component is classified as "Not For New Designs," indicating it has been superseded in onsemi's product portfolio. Identifying equivalent and substitute parts is necessary for applications requiring continued sourcing, legacy system maintenance, or design flexibility across multiple suppliers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the RGP10A is determined by the following critical parameters:

Electrical Compatibility Requirements:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
Current - Average Rectified (Io): Must equal or exceed 1 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) or equivalent
Reverse Recovery Time (trr): Must be ≤ 500 ns for fast recovery classification
Current - Reverse Leakage @ Vr: Must not exceed 5 µA @ rated voltage

Mechanical Compatibility Requirements:

Mounting Type: Through Hole (required)
Package / Case: DO-204AL, DO-41, or Axial (interchangeable mechanical footprints)

Compliance Requirements:

Substitute parts are grouped into two categories:

Direct Equivalents: Parts meeting all electrical parameters (50 V, 1 A, fast recovery ≤ 500 ns) with identical or superior performance characteristics and active product status.

Functional Alternatives: Parts meeting core electrical requirements (50 V, 1 A) with variations in recovery time, forward voltage, or product status, suitable for applications where exact parameter matching is not critical.

Frequently Asked Questions (FAQ)

Q: Can I directly replace RGP10A with RGP10A-E3/54?

A: Yes. RGP10A-E3/54 is a direct electrical and mechanical equivalent with identical specifications (50 V, 1 A, 150 ns trr, 1.3 V Vf). The primary difference is packaging format (Tape & Reel vs. Cut Tape) and active product status. Both are ROHS3 compliant and suitable for through-hole mounting in DO-41 packages.

Q: What is the difference between DO-41 and DO-204AL packages?

A: DO-41 and DO-204AL are equivalent designations for the same axial through-hole package. Both refer to a cylindrical component with leads at each end, suitable for insertion into standard through-hole PCB layouts. Mechanical compatibility is assured across all parts specifying these package types.

Q: Can I use 1N4933G as a substitute for RGP10A?

A: Yes, with minor performance trade-offs. 1N4933G meets the core requirements (50 V, 1 A, fast recovery ≤ 500 ns) and is ROHS3 compliant. However, it has a slightly lower forward voltage (1.2 V vs. 1.3 V), longer reverse recovery time (200 ns vs. 150 ns), and narrower temperature range (-55°C ~ 125°C vs. -65°C ~ 175°C). These differences are acceptable for most general-purpose rectification applications.

Q: Why is 1N4934GP-AP listed as a substitute if it has 100 V rating instead of 50 V?

A: 1N4934GP-AP is a functional alternative, not a direct equivalent. It provides a higher voltage rating (100 V) while maintaining the same 1 A current capacity and fast recovery characteristics. This part is suitable for applications where voltage margin is beneficial or where the circuit operates at voltages approaching the 50 V limit. It is not recommended for applications specifically designed for 50 V operation unless voltage headroom is required.

Q: Is 1N6076 a suitable replacement for RGP10A?

A: 1N6076 meets the voltage (50 V) and current (1.3 A, exceeds 1 A requirement) specifications with superior reverse recovery time (30 ns). However, it has two significant limitations: (1) RoHS non-compliant status, which restricts use in regulated industries and new designs; (2) Axial package format, which may differ from the original DO-41 package footprint depending on PCB layout. Use only in legacy applications where RoHS compliance is not required.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes have reverse recovery times ≤ 500 ns (RGP10A: 150 ns), enabling rapid switching and reduced switching losses in high-frequency applications. Standard recovery diodes have reverse recovery times > 500 ns (GP10A-E3/54: 3 µs). RGP10A is a fast recovery device; substitutes must maintain this characteristic unless the application specifically permits standard recovery performance.

Q: Can I use GP10A-E3/54 instead of RGP10A?

A: GP10A-E3/54 is not recommended as a direct substitute. While it meets voltage (50 V) and current (1 A) requirements, it is a standard recovery diode (3 µs trr) rather than fast recovery (150 ns trr). This 20-fold increase in recovery time will degrade performance in switching applications and increase power dissipation. Use only if the application does not require fast recovery characteristics.

Q: Which substitute offers the best compliance and availability?

A: RGP10A-E3/54 (Vishay) and PR1001-T (Diodes Incorporated) offer the best combination of direct electrical equivalence, active product status, ROHS3 compliance, and extended temperature ranges. Both are suitable for new designs and provide long-term sourcing stability.

Q: Are there any temperature range limitations I should consider?

A: Yes. RGP10A operates from -65°C ~ 175°C. Several substitutes have narrower ranges: 1N4933G, 1N4933GP-AP, and FR101G variants operate only to -55°C minimum and 125°C or 150°C maximum. If your application requires the full -65°C ~ 175°C range, select RGP10A-E3/54, PR1001-T, or GP10A-E3/54 (Vishay parts).

Q: What packaging options are available for substitutes?

A: Most substitutes are available in Cut Tape (CT) or Tape & Reel (TR) formats for automated assembly. RGP10A-E3/54 and PR1001-T are supplied in Tape & Reel. 1N6076 is supplied in Bulk format. Verify packaging compatibility with your procurement and assembly processes before selection.
