MUR460RL Equivalent & Substitute Parts

Part Overview

The MUR460RL is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 4 A average rectified current, manufactured by onsemi in the SWITCHMODE™ series. This device features fast recovery characteristics with a reverse recovery time of 75 ns and is packaged in DO-201AA/DO-27 axial configuration for through-hole mounting.

The MUR460RL is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and legacy system support. Substitute selection must maintain electrical performance within the application's tolerance parameters while considering packaging, compliance status, and thermal operating ranges.

Substitute Part Grouping Explanation

Substitution of the MUR460RL is determined by the following critical parameters:

Primary Electrical Requirements:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 600 V
Current - Average Rectified (Io): Must equal or exceed 4 A
Speed Classification: Fast Recovery characteristics (≤ 500ns, > 200mA)
Reverse Recovery Time (trr): Must equal or be less than 75 ns

Secondary Electrical Requirements:

Voltage - Forward (Vf) (Max): Should not significantly exceed 1.28 V @ rated current to maintain thermal efficiency
Current - Reverse Leakage @ Vr: Should not exceed 10 µA @ 600 V for leakage performance

Mechanical & Environmental Requirements:

Mounting Type: Through Hole (axial configuration)
Package / Case: DO-201AA, DO-27, or equivalent axial packages
Operating Temperature - Junction: Must support -65°C ~ 175°C range or equivalent

Compliance & Status:

RoHS Status: Preference for ROHS3 Compliant parts
Product Status: Active status preferred for long-term availability

Substitute parts are grouped into two categories:

Direct Equivalent (Identical Electrical & Mechanical Specifications): Parts that match all primary and secondary electrical requirements with identical or superior performance characteristics and compatible packaging.

Functional Equivalent (Reduced Current Rating): Parts that meet voltage and speed requirements but with reduced current ratings (3 A instead of 4 A). These are suitable only for applications where the actual operating current does not exceed the substitute part's rating.

Engineering Selection Recommendations

Primary Recommendation: MUR460RLG

The MUR460RLG is the direct equivalent replacement for the obsolete MUR460RL. Both parts are manufactured by onsemi and share identical electrical specifications: 600 V reverse voltage, 4 A average rectified current, 1.28 V forward voltage drop at 4 A, and 75 ns reverse recovery time. The MUR460RLG is classified as Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The packaging and mounting configuration are identical (DO-201AA, DO-27, axial through-hole). This part is the preferred direct substitute.

Secondary Recommendations for Current-Limited Applications:

For applications where the actual operating current does not exceed 3 A, the following parts provide functional equivalence with active product status and ROHS3 compliance:

1N5406-G (Comchip Technology): 600 V, 3 A, DO-201AD package, active status. Forward voltage is 1 V @ 3 A, lower than the MUR460RL. Speed classification is Standard Recovery (>500ns), which differs from the fast recovery characteristic of the MUR460RL.
1N5406GP-AP and 1N5406GP-TP (Micro Commercial Co): 600 V, 3 A, DO-201AD package, active status. Forward voltage is 1.1 V @ 3 A. Speed classification is Standard Recovery (>500ns). Operating temperature range is -55°C ~ 150°C, which does not extend to the lower -65°C limit of the MUR460RL.
FR305GP-AP and FR305GP-TP (Micro Commercial Co): 600 V, 3 A, DO-201AD package, active status. Forward voltage is 1.3 V @ 3 A, closely matching the MUR460RL. Speed classification is Fast Recovery (≤ 500ns), matching the MUR460RL characteristic. Reverse recovery time is 250 ns, which exceeds the MUR460RL's 75 ns specification.

Not Recommended for Direct Substitution:

1N6628U (Microchip Technology): Surface mount package (SQ-MELF, B). The MUR460RL is a through-hole axial device. This part is not mechanically compatible without circuit board redesign.
60S6-TP (Micro Commercial Co): 6 A current rating. While this part exceeds the MUR460RL's 4 A rating, it uses Standard Recovery speed classification (>500ns) rather than fast recovery, and the operating temperature range does not extend to -65°C.
BYV28-600-TAP (Vishay): Avalanche technology diode with 3.5 A rating and 210 ns reverse recovery time. The technology type and recovery time characteristics differ significantly from the MUR460RL's standard fast recovery design.
EGP30J (onsemi): Classified as "Not For New Designs," indicating this part is being phased out and should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 3 A rated diode in place of the 4 A MUR460RL?

A: Only if the actual operating current in your application does not exceed 3 A. The substitute part's current rating must be equal to or greater than the maximum current the circuit will draw. If your circuit requires 4 A or approaches this value, a 3 A substitute will overheat and fail prematurely.

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

A: Fast recovery diodes have reverse recovery times of 500 ns or less, while standard recovery diodes exceed 500 ns. Fast recovery diodes switch off more quickly, reducing switching losses and electromagnetic interference. If your application requires fast switching characteristics (such as in switch-mode power supplies), standard recovery diodes are not suitable substitutes.

Q: Why is MUR460RLG preferred over the original MUR460RL?

A: The MUR460RLG is electrically identical to the MUR460RL but is classified as Active product status with ROHS3 compliance. The original MUR460RL is obsolete and non-compliant with RoHS regulations. The MUR460RLG ensures continued availability, regulatory compliance, and support from the manufacturer.

Q: Can I use a surface-mount diode like the 1N6628U instead of the through-hole MUR460RL?

A: No. The 1N6628U is a surface-mount device in SQ-MELF package, while the MUR460RL is a through-hole axial component. These require different circuit board layouts and assembly processes. Mechanical compatibility is not possible without redesigning the circuit board.

Q: What does "DO-201AD" package mean, and is it compatible with "DO-27"?

A: DO-201AD and DO-27 are both axial through-hole packages for diodes. DO-27 is an older designation, and DO-201AD is the modern equivalent. These packages are mechanically and electrically compatible for through-hole mounting applications. Both fit standard 0.3-inch lead spacing on circuit boards.

Q: If I need 4 A capacity, which substitute should I choose?

A: The MUR460RLG is the only substitute that maintains the full 4 A current rating. All other listed substitutes are rated for 3 A or lower and are not suitable for applications requiring 4 A operation.

Q: Does operating temperature range affect my substitution choice?

A: Yes. The MUR460RL operates from -65°C to 175°C. Some substitutes have narrower ranges (for example, 1N5406GP-AP operates from -55°C to 150°C). If your application requires operation at -65°C or above 150°C, verify that the substitute part's temperature range is adequate.

Q: What is reverse leakage current, and why does it matter?

A: Reverse leakage current is the small amount of current that flows through a reverse-biased diode. The MUR460RL has a maximum reverse leakage of 10 µA @ 600 V. Lower leakage (such as 5 µA in some substitutes) indicates better reverse blocking performance and lower power dissipation in standby conditions. Higher leakage would increase power consumption and heat generation.

Q: Can I use the 60S6-TP (6 A rated) as a substitute for the 4 A MUR460RL?

A: The 60S6-TP has sufficient current capacity, but it uses Standard Recovery speed classification (>500ns) instead of fast recovery (≤ 500ns). If your application requires fast switching characteristics, this substitute is not appropriate. Additionally, the operating temperature range (-55°C to 150°C) does not extend to the -65°C lower limit of the MUR460RL.
