MUR415RL Equivalent & Substitute Parts

Part Overview

The MUR415RL is a general-purpose rectifier diode manufactured by onsemi, rated for 150 V DC reverse voltage and 4 A average rectified current. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. The MUR415RL features fast recovery characteristics with a reverse recovery time of 35 ns and is packaged in DO-201AA/DO-27 axial configuration for through-hole mounting applications.

Substitute Part Grouping Explanation

Substitute parts for the MUR415RL are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 4 A (or higher)
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 35 ns or lower
Mounting Type: Through Hole
Operating Temperature Range: Compatible with -65°C ~ 175°C minimum

Substitution Logic: The BYV98-150-TR and BYV98-150-TAP variants meet all critical electrical parameters with identical 150 V reverse voltage rating, 4 A average rectified current, and 35 ns reverse recovery time. Both are manufactured by Vishay General Semiconductor - Diodes Division and maintain active product status with RoHS3 compliance. The BYV28-150-TAP provides an alternative with reduced current rating (3.5 A) and lower reverse leakage (1 µA), suitable for applications not requiring full 4 A capacity.

Engineering Selection Recommendations

BYV98-150-TR and BYV98-150-TAP (Primary Substitutes): These parts provide direct electrical equivalence to the MUR415RL with identical 150 V reverse voltage, 4 A current rating, and 35 ns reverse recovery time. Both maintain active product status and achieve ROHS3 compliance, addressing regulatory requirements that the obsolete MUR415RL cannot satisfy. The BYV98-150-TR is supplied in Tape & Reel packaging, while BYV98-150-TAP is supplied in Tape & Box configuration. Selection between these variants depends on procurement and assembly requirements.

BYV28-150-TAP (Secondary Substitute): This part qualifies as a substitute for applications where the full 4 A current capacity is not required. The BYV28-150-TAP delivers superior reverse leakage performance (1 µA versus 5 µA) and faster recovery time (30 ns versus 35 ns) while maintaining the 150 V voltage rating. This option is suitable for lower-current circuit implementations and provides enhanced reliability characteristics.

Compliance Considerations: All Vishay substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages over the non-compliant MUR415RL. The operating temperature range of the substitute parts (-55°C ~ 175°C) is narrower at the lower bound compared to the MUR415RL (-65°C ~ 175°C); applications requiring operation below -55°C require design verification.

Frequently Asked Questions (FAQ)

Q: Can BYV98-150-TR and BYV98-150-TAP be used interchangeably with MUR415RL?

A: Yes, both BYV98 variants meet the critical electrical specifications of the MUR415RL: 150 V reverse voltage, 4 A average rectified current, and 35 ns reverse recovery time. The primary difference is packaging format (Tape & Reel versus Tape & Box) and physical package style (SOD-64 versus DO-201AA/DO-27). PCB layout and mechanical mounting must accommodate the SOD-64 axial package configuration.

Q: What is the difference between BYV98-150-TR and BYV98-150-TAP?

A: Both parts are electrically identical with the same electrical specifications. The difference is in packaging and supply format: BYV98-150-TR is supplied in Tape & Reel (TR) configuration for automated assembly, while BYV98-150-TAP is supplied in Tape & Box (TB) configuration. Selection depends on procurement volume and assembly process requirements.

Q: Is BYV28-150-TAP suitable as a substitute for all MUR415RL applications?

A: BYV28-150-TAP is suitable only for applications where the average rectified current requirement does not exceed 3.5 A. The part maintains the 150 V voltage rating and fast recovery characteristics but has reduced current capacity. Applications requiring the full 4 A rating must use BYV98-150-TR or BYV98-150-TAP.

Q: What are the package differences between MUR415RL and the substitute parts?

A: The MUR415RL uses DO-201AA/DO-27 axial package, while all Vishay substitutes use SOD-64 axial package. Both are through-hole axial configurations suitable for PCB mounting, but the physical dimensions differ. PCB footprint and lead spacing must be verified for mechanical compatibility.

Q: Are there temperature range limitations when substituting?

A: The substitute parts operate from -55°C to 175°C, compared to the MUR415RL range of -65°C to 175°C. Applications requiring operation below -55°C cannot use these substitutes without design modification or alternative component selection.

Q: What is the compliance advantage of using Vishay substitutes?

A: All Vishay substitute parts are ROHS3 compliant and REACH unaffected, whereas the MUR415RL is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the Vishay substitutes provide regulatory compliance without design changes.

Q: How do forward voltage characteristics compare?

A: The MUR415RL specifies 890 mV forward voltage at 4 A, while Vishay substitutes specify 1.1 V at 5 A. The higher specification voltage for Vishay parts reflects measurement at higher current. Circuit designs dependent on specific forward voltage characteristics require verification with actual operating conditions.

Q: What is the reverse leakage difference between parts?

A: The MUR415RL has 5 µA reverse leakage at 150 V, BYV98 variants have 10 µA, and BYV28-150-TAP has 1 µA. Applications sensitive to leakage current should use BYV28-150-TAP for superior performance or verify that BYV98 leakage is acceptable for the circuit design.
