Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching essential electrical and mechanical characteristics, including: voltage rating, average rectified current, package type, mounting style, compliance status, moisture sensitivity level, and reverse leakage current. Diodes listed as equivalents share these parameters within allowed tolerances according to the Diodes, Rectifiers industry conventions for compatibility.

Parameters considered for grouping:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Package / Case
• Mounting Type
• Compliance (RoHS, REACH)
• MSL (Moisture Sensitivity Level)
• Reverse leakage current
• Speed and recovery time, as specified

Parameter Comparison

Engineering Selection Recommendations

Both SF12G and 1N4002GP-E3/54 are active, RoHS3 compliant, and have REACH unaffected status. Both devices are rated MSL 1 (unlimited), and are in the same ECCN and HTSUS categories. These certifications support use in regulated and compliant applications where such requirements must be met. Availability in through-hole, DO-204AL (DO-41) packages ensures compatibility for mechanical and PCB assembly processes.
