MUR460-TP Equivalent & Substitute Parts

Part Overview

The MUR460-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 4 A average rectified current in a DO-201AD axial through-hole package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design requirements and production continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with comparable performance characteristics within acceptable parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the MUR460-TP is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a minimum DC reverse voltage rating of 600 V to ensure equivalent circuit protection and reliability.

Current Rating: The average rectified current capacity must be sufficient for the application. Parts rated at 4 A or higher are direct equivalents; parts rated below 4 A (such as 3 A variants) are functional substitutes with reduced current capacity.

Recovery Characteristics: Fast recovery diodes (≤ 500 ns) are preferred equivalents. Standard recovery diodes (> 500 ns) function as substitutes in applications where switching speed is not critical.

Package and Mounting: Through-hole axial packages (DO-201AD, DO-201AA, DO-27) are mechanically and electrically interchangeable. Surface-mount packages represent functional alternatives only when board redesign is acceptable.

Temperature Range: Operating temperature ranges of -55°C to 150°C or broader are acceptable equivalents.

Compliance: RoHS3 compliance and REACH unaffected status are maintained across all listed substitutes.

Engineering Selection Recommendations

Direct Equivalents (Preferred):

MUR460GP-TP and MUR460RLG are direct functional equivalents to the MUR460-TP. Both maintain 600 V reverse voltage rating, 4 A average rectified current, fast recovery characteristics, and through-hole axial packaging. MUR460GP-TP is manufactured by the same supplier (Micro Commercial Co) with active product status. MUR460RLG is manufactured by onsemi with active status and broader operating temperature range (-65°C to 175°C). Both parts are RoHS3 compliant and REACH unaffected.

Functional Substitutes (Current Derating):

The 1N5406 series (1N5406-E3/54, 1N5406-E3/73, 1N5406-G, 1N5406G) and 1N5406RLG provide functional substitution with reduced current capacity (3 A versus 4 A). These parts maintain 600 V reverse voltage rating and DO-201AD axial packaging. All are RoHS3 compliant and REACH unaffected. The 1N5406 variants employ standard recovery characteristics (> 500 ns), making them suitable for applications where switching speed is not a design constraint. 1N5406RLG carries "Not For New Designs" status and should be avoided for new development.

Alternative Packages:

1N6628U (Microchip Technology) provides equivalent electrical performance (660 V, 1.75 A, fast recovery) but requires surface-mount board redesign due to SQ-MELF packaging. This option is suitable only when PCB layout modification is acceptable.

BYV28-600-TAP (Vishay General Semiconductor) offers 600 V, 3.5 A avalanche diode technology in SOD-64 through-hole package. Avalanche technology provides additional overvoltage protection but with longer reverse recovery time (210 ns). This part is suitable for applications requiring avalanche suppression capability.

Frequently Asked Questions (FAQ)

Q: Can MUR460GP-TP directly replace MUR460-TP without circuit modification?

A: Yes. MUR460GP-TP maintains identical electrical specifications (600 V, 4 A, fast recovery, 60 ns reverse recovery time) and identical DO-201AD axial through-hole packaging. The only difference is packaging format (Tape & Reel versus bulk), which does not affect circuit performance.

Q: What is the impact of using a 3 A rated diode (1N5406 series) in place of the 4 A MUR460-TP?

A: The 1N5406 series provides functional substitution with 25% reduced current capacity. Circuit operation remains valid provided the application's average rectified current does not exceed 3 A. Thermal management and reliability margins are reduced. This substitution is acceptable only when application current requirements are confirmed below 3 A.

Q: Why do some substitutes have longer reverse recovery times?

A: Reverse recovery time (trr) varies by diode technology and manufacturing process. The MUR460-TP specifies 60 ns fast recovery. The 1N5406 series does not specify trr but uses standard recovery technology (> 500 ns). Longer recovery times increase switching losses in high-frequency applications. Standard recovery diodes are suitable for line-frequency rectification and low-frequency switching applications.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance and REACH unaffected status, matching the MUR460-TP environmental compliance profile.

Q: Can surface-mount alternatives (1N6628U) be used as direct replacements?

A: No. Surface-mount packages require PCB redesign and different assembly processes. 1N6628U is a functional electrical equivalent (660 V, 1.75 A, fast recovery) but is not a direct mechanical replacement. Use only when board redesign is planned.

Q: What is the difference between MUR460RLG and MUR460GP-TP?

A: Both are 600 V, 4 A fast recovery diodes with identical electrical performance. MUR460RLG is manufactured by onsemi with operating temperature range -65°C to 175°C and longer reverse recovery time (75 ns versus 60 ns). MUR460GP-TP is manufactured by Micro Commercial Co with operating temperature range -55°C to 150°C. Selection depends on temperature requirements and supplier preference.

Q: Should 1N5406RLG be used for new designs?

A: No. 1N5406RLG carries "Not For New Designs" product status. Use active alternatives such as 1N5406-E3/73 or 1N5406G for new development.

Q: How does BYV28-600-TAP differ from MUR460-TP?

A: BYV28-600-TAP is an avalanche diode rated 600 V, 3.5 A with SOD-64 through-hole packaging. Avalanche technology provides overvoltage clamping capability, making it suitable for transient suppression applications. Reverse recovery time is longer (210 ns). This part is a functional alternative for applications requiring avalanche protection, not a direct replacement for standard rectification.
