Substitute Part Grouping Explanation

Substitution eligibility for the SJ6012DRP is determined by strict equivalence across the following criteria:

• Off-state voltage rating: 600 V
• RMS on-state current rating: 12 A
• Gate trigger voltage and current specifications
• On-state voltage drop characteristics
• Package configuration: TO-252 (DPAK) surface mount
• SCR recovery type classification
• Operating temperature range: -40°C to 150°C
• Compliance certifications: RoHS3, MSL Level 1

The SJ6012D1RP meets all these parameters identically, establishing it as a parametric equivalent within the SJ series family.
