UG1D-M3/54 Equivalent & Substitute Parts
Part Overview
The UG1D-M3/54 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This through-hole component operates at 200 V DC reverse voltage with 1 A average rectified current and features fast recovery characteristics with a 25 ns reverse recovery time. The device is housed in a DO-204AL (DO-41) axial package and is classified as an active product with ROHS3 compliance.
Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences while maintaining identical functional specifications.

Substitute Part Grouping Explanation
Substitute parts for the UG1D-M3/54 are qualified based on the following electrical and mechanical parameters:
Critical Matching Parameters:
- Voltage - DC Reverse (Vr) (Max): 200 V
- Current - Average Rectified (Io): 1 A
- Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
- Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
- Mounting Type: Through Hole
- Package / Case: DO-204AL, DO-41, Axial
- Operating Temperature - Junction: -55°C to 150°C
- RoHS Status: ROHS3 Compliant
All identified substitute parts meet these core electrical specifications and mechanical compatibility requirements. Variations in reverse recovery time (trr), reverse leakage current, and capacitance are noted but do not preclude functional equivalence within the specified parameter ranges. Packaging format differences (Tape & Reel versus Cut Tape) represent logistical variations without impact on electrical performance.

Engineering Selection Recommendations
Vishay UG1D Series (UG1D-E3/54, UG1D-E3/73): These parts are direct parametric equivalents to the UG1D-M3/54, differing only in packaging format (Cut Tape versus Tape & Reel). Both maintain identical electrical specifications including the 25 ns reverse recovery time. Selection between these variants depends on procurement and assembly requirements. Both are ROHS3 compliant and carry active product status.
Panjit ER102_R2_00001: This part meets all core electrical requirements with identical voltage and current ratings.

REACH status is listed as affected. The part is ROHS3 compliant and active. This variant is appropriate for extended low-temperature applications.
Taiwan Semiconductor Corporation SF14GH: This part meets all electrical specifications with 35 ns reverse recovery time and includes automotive-grade qualification (AEC-Q101). Operating temperature range is -55°C to 150°C. The part is ROHS3 compliant and active. This variant is designated for automotive applications requiring AEC-Q101 certification.
Frequently Asked Questions (FAQ)
Q: Can UG1D-E3/54 and UG1D-E3/73 be used interchangeably with UG1D-M3/54?
A: Yes. These parts are parametrically identical to the UG1D-M3/54 in all electrical specifications. The difference is packaging format: UG1D-M3/54 is supplied in Tape & Reel format, while UG1D-E3/54 and UG1D-E3/73 are supplied in Cut Tape format. Electrical performance and mechanical compatibility are equivalent.
Q: What is the significance of the 25 ns versus 35 ns reverse recovery time difference?
A: The UG1D-M3/54 has a 25 ns reverse recovery time, while ER102_R2_00001, SF14G, and SF14GH have 35 ns. Both values fall within the fast recovery classification (≤ 500ns, > 200mA). The 10 ns difference represents a minor variation that does not affect functional equivalence for general-purpose rectification applications within the specified parameter envelope.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All identified substitute parts carry ROHS3 compliance status, matching the UG1D-M3/54 environmental qualification.
Q: What is the difference between SF14G and SF14GH?
A: SF14G is a standard industrial-grade part with operating temperature range -65°C to 150°C. SF14GH is automotive-grade with AEC-Q101 qualification and operating temperature range -55°C to 150°C. Both meet the electrical specifications of the UG1D-M3/54. Selection depends on application requirements and automotive certification needs.
Q: Can ER102_R2_00001 be used in all applications where UG1D-M3/54 is specified?
A: ER102_R2_00001 meets all core electrical specifications and is mechanically compatible. The reverse leakage current is lower (1 µA versus 5 µA), which is advantageous. The 35 ns reverse recovery time is within acceptable limits for general-purpose rectification. This part is suitable for equivalent applications.
Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?
A: No. Packaging format is a logistical consideration only. Tape & Reel and Cut Tape formats contain identical components with identical electrical specifications. Format selection is determined by assembly equipment and procurement workflow requirements.
Q: Is SF14GH suitable for non-automotive applications?
A: Yes. SF14GH meets all electrical specifications required for general-purpose rectification. The automotive-grade qualification and AEC-Q101 certification represent additional qualifications that do not restrict use in non-automotive applications. This part is functionally equivalent to the UG1D-M3/54 for any application within the specified electrical envelope.
