Substitute Part Grouping Explanation

Substitute parts for the UG1D-M3/73 are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Reverse Recovery Time (trr): 25 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Package / Case: DO-204AL, DO-41, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The UG1D-E3/73 meets all substitution criteria and is classified as a parametric equivalent. The primary difference is packaging format: UG1D-M3/73 is supplied in standard packaging, while UG1D-E3/73 is supplied in Cut Tape (CT) format. Both devices share identical electrical specifications and mechanical compatibility.

Parameter Comparison
