Engineering Selection Recommendations

Tier 1 - Direct Replacement (Recommended for Pin-Compatible Designs):

MUR410G and MUR410RLG from onsemi are the primary substitutes for MUR410-TP. Both parts maintain the MUR410 base product number, deliver identical 100 V / 4 A electrical specifications, and are classified as active products. MUR410G is supplied in bulk packaging, while MUR410RLG is supplied in cut tape format. Both are ROHS3 compliant and REACH unaffected. The onsemi parts feature improved reverse recovery time (35 ns versus 45 ns) and lower forward voltage drop (890 mV versus 1 V at 4 A), resulting in reduced power dissipation. Operating temperature range extends to 175°C, exceeding the original specification. These parts are suitable for direct substitution in existing PCB layouts designed for DO-201AA or DO-27 axial packages.

Tier 2 - Functional Equivalents (Package Format Change Required):

BYV98-100-TAP and BYV98-100-TR from Vishay provide 100 V / 4 A ratings with fast recovery characteristics (35 ns) and are active products. These avalanche diodes use SOD-64 package format, requiring PCB layout modification. Both are ROHS3 compliant and REACH unaffected. BYV98-100-TAP is supplied in tape and box format; BYV98-100-TR is supplied in tape and reel format. Selection between these two depends on procurement and assembly requirements.

BYV28-100-TAP and BYV28-100-TR from Vishay provide 100 V / 3.5 A ratings with superior reverse recovery time (30 ns). These parts are suitable when circuit design accommodates the reduced current rating. Both use SOD-64 package format and are active products with ROHS3 compliance.

Tier 3 - Current-Limited Alternatives (Reduced Current Rating):

1N5401-E3/54, 1N5401-E3/73, GP30B-E3/54, and GP30B-E3/73 are 100 V / 3 A diodes in DO-201AD package format. These parts maintain package compatibility with the original MUR410-TP but deliver reduced current capacity. All are active products with ROHS3 compliance. These alternatives are applicable only when circuit design permits operation at 3 A maximum current. The 1N5401 series exhibits standard recovery characteristics (>500ns), while the GP30B series (SUPERECTIFIER®) provides extended recovery time (5 µs). Selection among these four depends on packaging format preference (cut tape versus bulk) and supplier availability.

Compliance & Certification:

All recommended substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original MUR410-TP certification profile. All parts are rated for through-hole mounting and operate within industrial temperature ranges. Moisture sensitivity level is either 1 (unlimited) or not applicable, indicating no special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can MUR410G directly replace MUR410-TP without PCB modification?

A: MUR410G is electrically equivalent and maintains the same base product number. However, package format compatibility depends on PCB design. MUR410G uses DO-201AA or DO-27 axial package, while MUR410-TP uses DO-201AD. Verify PCB footprint specifications before substitution. If footprints are identical, direct substitution is possible without modification.

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

A: Recovery speed refers to reverse recovery time (trr), the interval required for a diode to transition from forward conduction to reverse blocking. MUR410-TP specifies fast recovery (≤ 500ns, trr = 45 ns). Substitute parts MUR410G, MUR410RLG, BYV98, and BYV28 series maintain fast recovery characteristics. Parts 1N5401 and GP30B series specify standard recovery (>500ns), resulting in slower switching transitions. Fast recovery diodes are required for high-frequency switching applications; standard recovery diodes are suitable for lower-frequency rectification.

Q: Why do some substitutes have lower current ratings (3 A versus 4 A)?

A: 1N5401-E3/54, 1N5401-E3/73, GP30B-E3/54, and GP30B-E3/73 are rated for 3 A average rectified current, compared to the MUR410-TP specification of 4 A. These parts are functional equivalents only when circuit design permits operation within the 3 A limit. Exceeding the rated current causes excessive power dissipation and thermal stress. Verify circuit current requirements before selecting current-limited alternatives.

Q: What is the significance of package format differences (DO-201AD versus SOD-64)?

A: DO-201AD and SOD-64 are both through-hole axial packages but differ in physical dimensions and PCB footprint. DO-201AD is a larger package format; SOD-64 is more compact. BYV98 and BYV28 series use SOD-64 format, requiring PCB layout redesign if the original design specifies DO-201AD. Verify PCB footprint compatibility and available board space before selecting SOD-64 alternatives.

Q: Are there performance differences between MUR410G and MUR410RLG?

A: MUR410G and MUR410RLG are electrically identical, both from onsemi's SWITCHMODE™ series with 100 V / 4 A ratings, 35 ns reverse recovery time, and 890 mV forward voltage drop. The difference is packaging format: MUR410G is supplied in bulk; MUR410RLG is supplied in cut tape. Selection depends on procurement method and assembly process requirements. Both are active products with identical compliance certifications.

Q: Can BYV98-100-TAP and BYV98-100-TR be used interchangeably?

A: BYV98-100-TAP and BYV98-100-TR are electrically identical Vishay avalanche diodes with 100 V / 4 A ratings and 35 ns reverse recovery time. The difference is packaging format: BYV98-100-TAP is supplied in tape and box; BYV98-100-TR is supplied in tape and reel. Selection depends on assembly equipment compatibility and procurement preferences. Both are active products with identical electrical specifications and compliance certifications.

Q: What is the operating temperature range difference between MUR410-TP and its substitutes?

A: MUR410-TP specifies -55°C to 150°C junction temperature range. MUR410G and MUR410RLG extend this to -65°C to 175°C. BYV98 and BYV28 series also specify -55°C to 175°C. GP30B series specifies -65°C to 175°C. 1N5401 series specifies -50°C to 150°C. Verify application temperature requirements before substitution. Extended temperature range provides additional design margin for high-temperature environments.

Q: Is forward voltage drop a critical parameter for substitution?

A: Forward voltage drop (Vf) affects power dissipation and circuit efficiency. MUR410-TP specifies 1 V @ 4 A. MUR410G and MUR410RLG specify 890 mV @ 4 A, resulting in lower power loss. BYV98 and BYV28 series specify 1.1 V @ 5 A. 1N5401 and GP30B series specify 1.2 V @ 3 A. Lower forward voltage drop reduces heat generation and improves efficiency. Verify thermal design compatibility when substituting parts with different Vf specifications.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive 3 requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. All recommended substitute parts maintain ROHS3 compliance, ensuring environmental and regulatory compatibility with the original MUR410-TP specification.
