RGP10B-M3/54 Equivalent & Substitute Parts

Part Overview

The RGP10B-M3/54 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 100 V DC reverse voltage and 1 A average rectified current in a DO-204AL (DO-41) through-hole axial package. This device is part of the SUPERECTIFIER® series and features fast recovery characteristics with a reverse recovery time of 150 ns.

The RGP10B-M3/54 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production, repair, and legacy system support.

Engineering Selection Recommendations

For Direct Replacement (Through-Hole Axial, 100 V / 1 A):

RGP10B-E3/54 and RGP10BE-E3/54 are the primary substitutes for the obsolete RGP10B-M3/54. Both parts are manufactured by Vishay and maintain identical electrical specifications. These parts carry Active product status and are ROHS3 compliant. RGP10BE-E3/54 offers higher inventory availability (11,760 pcs vs. 9,513 pcs).

For Active Product Status with Equivalent Performance:

EGP10B (Fairchild Semiconductor) provides 100 V / 1 A performance in DO-204AL packaging with Active product status. This part features superior reverse recovery time (50 ns vs. 150 ns) and lower forward voltage (950 mV vs. 1.3 V), resulting in reduced power dissipation. Inventory availability is substantial (66,152 pcs).

FR102G B0G and FR102G R1G (Taiwan Semiconductor Corporation) are Active alternatives with identical electrical specifications to the original part. Operating temperature range is reduced to -55°C to 150°C.

1N4934-T (Diodes Incorporated) is an Active alternative with 100 V / 1 A rating. Reverse recovery time is 200 ns, and forward voltage is 1.2 V @ 1 A. Operating temperature range is -65°C to 150°C.

For Higher Current Capability:

MUR210RLG (onsemi) provides 100 V / 2 A capability with superior reverse recovery time (30 ns) and lower forward voltage (940 mV @ 2 A). This part is suitable for applications requiring additional current margin. Operating temperature range extends to 175°C.

For Surface-Mount Applications:

MURA110T3G (onsemi) provides equivalent 100 V / 1 A performance in SMA surface-mount packaging. This part features fast reverse recovery (30 ns) and low forward voltage (875 mV @ 1 A). Operating temperature range is -65°C to 175°C.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status, consistent with the original part. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all through-hole variants, indicating no special moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can RGP10B-E3/54 or RGP10BE-E3/54 be used as direct replacements for RGP10B-M3/54?

A: Yes. RGP10B-E3/54 and RGP10BE-E3/54 are parametric equivalents with identical electrical specifications (100 V, 1 A, 150 ns reverse recovery time, 1.3 V forward voltage). The primary difference is packaging format (Cut Tape vs. bulk) and product status (Active vs. Obsolete). Both parts are suitable for direct substitution in through-hole applications.

Q: What is the difference between the Vishay RGP10B variants and the Diodes Incorporated 1N4934-T?

A: Both parts meet the 100 V / 1 A core requirements and fast recovery classification. The 1N4934-T has a slightly lower forward voltage (1.2 V vs. 1.3 V) and longer reverse recovery time (200 ns vs. 150 ns). Operating temperature range for 1N4934-T is -65°C to 150°C, compared to -65°C to 175°C for RGP10B variants. The 1N4934-T is Active and widely available (25,290 pcs).

Q: Is EGP10B a suitable substitute despite the lower forward voltage?

A: Yes. EGP10B meets all core substitution criteria: 100 V reverse voltage, 1 A average rectified current, fast recovery classification, and through-hole DO-204AL packaging. The lower forward voltage (950 mV vs. 1.3 V) and faster reverse recovery time (50 ns vs. 150 ns) represent improved performance characteristics. Operating temperature range is -65°C to 150°C. EGP10B is Active with substantial inventory availability.

Q: Can MUR210RLG be used as a substitute for applications requiring only 1 A?

A: Yes. MUR210RLG is rated for 100 V / 2 A, exceeding the 1 A requirement. The higher current rating provides design margin without compromising performance. MUR210RLG features superior reverse recovery time (30 ns) and lower forward voltage (940 mV @ 2 A). Operating temperature range extends to 175°C. This part is suitable for applications where additional current capability is beneficial or where future design modifications may increase current requirements.

Q: What are the package differences between through-hole and surface-mount alternatives?

A: The original RGP10B-M3/54 and most substitutes (RGP10B-E3/54, EGP10B, FR102G variants, 1N4934-T, 1N4934RLG, MUR210RLG, 1N6077) are through-hole axial or DO-41 packages requiring PCB holes and wave soldering or manual insertion. MURA110T3G is a surface-mount SMA package (DO-214AC) requiring reflow soldering and SMD assembly equipment. Surface-mount alternatives are not interchangeable with through-hole designs without PCB redesign.

Q: Are there compliance or certification differences between substitutes?

A: All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all through-hole variants, indicating no special moisture handling requirements during storage or assembly. MURA110T3G (surface-mount) also carries MSL 1. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Why is 1N4934RLG marked "Not For New Designs"?

A: 1N4934RLG carries a "Not For New Designs" product status from onsemi, indicating the manufacturer is transitioning away from this part. While the part is currently available (5,300 pcs inventory) and meets electrical specifications, it is not recommended for new product designs. Active alternatives such as 1N4934-T, EGP10B, or Vishay RGP10B-E3/54 are preferred for new designs.

Q: What is the significance of reverse recovery time differences among substitutes?

A: Reverse recovery time (trr) affects switching performance and electromagnetic interference (EMI) characteristics. The original RGP10B-M3/54 has 150 ns trr. Substitutes range from 30 ns (MUR210RLG, EGP10B, MURA110T3G, 1N6077) to 300 ns (1N4934RLG). Faster recovery times reduce switching losses and EMI but may not be necessary for all applications. Slower recovery times are acceptable in low-frequency rectification circuits where switching speed is not critical.

Q: Can FR102G variants be used in applications requiring the full -65°C to 175°C temperature range?

A: No. FR102G B0G and FR102G R1G are rated for -55°C to 150°C, which is narrower than the original RGP10B-M3/54 (-65°C to 175°C). These parts are not suitable for applications requiring operation below -55°C or above 150°C. For full temperature range compatibility, use RGP10B-E3/54, RGP10BE-E3/54, MUR210RLG, or MURA110T3G.

Q: Is 1N6077 suitable as a substitute despite the higher current rating and different forward voltage specification?

A: 1N6077 meets the core voltage (100 V) and speed (fast recovery ≤ 500ns) requirements. However, the forward voltage specification (1.76 V @ 18.8 A) is measured at a different current level than the original part (1.3 V @ 1 A), making direct comparison difficult. The higher current rating (1.3 A vs. 1 A) provides design margin. 1N6077 is Active and RoHS non-compliant, which may be a consideration for new designs. This part is suitable for applications where RoHS compliance is not required and higher current capability is acceptable.
