Engineering Selection Recommendations

Direct Equivalents (100 V, 1 A Rating):

MUR110G and MUR110RLG are direct electrical equivalents to the MUR110GP-TP. Both are manufactured by onsemi under the SWITCHMODE™ series with Active product status. These parts maintain identical voltage and current ratings while offering improved performance characteristics: lower forward voltage drop (875 mV vs. 970 mV), faster reverse recovery time (35 ns vs. 45 ns), and lower reverse leakage current (2 µA vs. 5 µA). Operating temperature range extends to 175°C, exceeding the MUR110GP-TP specification. Both parts are ROHS3 compliant and carry REACH Unaffected status. Selection between MUR110G (Bulk packaging) and MUR110RLG (Cut Tape packaging) depends on procurement and assembly requirements.

UG1B-E3/54 (Vishay) is an electrical equivalent with identical 100 V, 1 A ratings and ROHS3 compliance. This part features the fastest reverse recovery time (25 ns) among 100 V substitutes and forward voltage of 950 mV. Operating temperature range is -55°C to 150°C, matching the lower bound of the MUR110GP-TP. Cut Tape packaging is provided.

RGP10B-E3/73 (Vishay SUPERECTIFIER® series) and UF4002 R1G (Taiwan Semiconductor Corporation) are functionally compatible 100 V, 1 A rectifiers with Active product status and ROHS3 compliance. Both maintain the required electrical specifications, though with higher forward voltage drops (1.3 V and 1.0 V respectively) and longer reverse recovery times (150 ns and 50 ns). These parts are suitable for applications where the MUR110GP-TP performance envelope is not critical.

Higher Voltage Alternative:

MUR1100ERLG (onsemi SWITCHMODE™ series) provides 1000 V reverse voltage rating with 1 A current capacity. This part is suitable only for applications requiring higher voltage blocking capability than the original 100 V specification. Forward voltage (1.75 V) and reverse recovery time (100 ns) are significantly higher. Active product status and ROHS3 compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can MUR110G or MUR110RLG be used as direct replacements for MUR110GP-TP?

A: Yes. Both parts are manufactured by onsemi and maintain identical electrical ratings: 100 V reverse voltage and 1 A average rectified current. Both are through-hole axial packages compatible with DO-41 footprints. MUR110G and MUR110RLG offer improved performance with lower forward voltage drop, faster reverse recovery time, and lower reverse leakage current. Both carry Active product status and ROHS3 compliance.

Q: What is the difference between MUR110G and MUR110RLG?

A: The electrical specifications are identical. The primary difference is packaging: MUR110G is supplied in Bulk packaging, while MUR110RLG is supplied in Cut Tape (CT) packaging. Selection depends on procurement method and assembly process requirements.

Q: Is UG1B-E3/54 compatible with the MUR110GP-TP application?

A: Yes. UG1B-E3/54 maintains the same 100 V reverse voltage and 1 A current ratings in a through-hole DO-41 package. The part is manufactured by Vishay with Active product status and ROHS3 compliance. Forward voltage is 950 mV (compared to 970 mV), and reverse recovery time is 25 ns (faster than 45 ns). Operating temperature range is -55°C to 150°C, which covers the MUR110GP-TP lower temperature bound.

Q: When should RGP10B-E3/73 or UF4002 R1G be selected?

A: These parts are functionally compatible 100 V, 1 A rectifiers suitable for general-purpose applications where the MUR110GP-TP performance envelope is not critical. Both maintain Active product status and ROHS3 compliance. RGP10B-E3/73 is part of the Vishay SUPERECTIFIER® series with extended temperature range (-65°C to 175°C). UF4002 R1G is manufactured by Taiwan Semiconductor Corporation. Selection should be based on availability, cost, and specific application requirements.

Q: Can MUR1100ERLG replace MUR110GP-TP?

A: MUR1100ERLG is not a direct replacement. While both are 1 A rectifiers, MUR1100ERLG is rated for 1000 V reverse voltage compared to 100 V for the MUR110GP-TP. This part is suitable only for applications requiring higher voltage blocking capability. Forward voltage (1.75 V) and reverse recovery time (100 ns) are significantly higher than the original part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status and REACH Unaffected designation, matching the environmental compliance of the MUR110GP-TP.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in multiple packaging formats: Bulk (MUR110G), Cut Tape (MUR110RLG, UG1B-E3/54, MUR1100ERLG), and standard DO-204AL (DO-41) packages (RGP10B-E3/73, UF4002 R1G). Selection depends on procurement and assembly requirements.

Q: Do all substitutes support the same operating temperature range as MUR110GP-TP?

A: No. The MUR110GP-TP operates from -65°C to 150°C. MUR110G and MUR110RLG extend to 175°C. UG1B-E3/54 and UF4002 R1G operate from -55°C to 150°C. RGP10B-E3/73 operates from -65°C to 175°C. Application temperature requirements should be verified before selection.
