Key Parameters

Substitute Part Grouping Explanation

Substitution for diode rectifiers in this category is determined by matching electrical and mechanical characteristics, specifically:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Recovery speed classification
• Mounting type and package/case
• Product status
• RoHS and compliance certifications

These parameters ensure functional and physical compatibility for use in circuit designs and replacement scenarios.

Parameter Comparison
