Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FR151G A0G are identified based on the following critical electrical and mechanical parameters:

Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Package / Case: DO-204AC (DO-15) axial through-hole form factor
• Mounting Type: Through Hole
• Technology: Standard rectifier diode classification
• RoHS Compliance: ROHS3 Compliant

Performance Considerations:

• Current - Average Rectified (Io): Equal to or greater than 1.5 A
• Reverse Recovery Time (trr): Fast recovery classification (≤ 500 ns)
• Operating Temperature Range: Minimum -55°C to 150°C junction temperature capability

The EGP20A-E3/54 qualifies as a direct substitute because it maintains identical reverse voltage rating, package form factor, and through-hole mounting configuration while providing enhanced current capacity (2 A versus 1.5 A) and improved reverse recovery characteristics (50 ns versus 150 ns). These performance enhancements ensure backward compatibility in applications designed for the FR151G A0G.
