Substitute Part Grouping Explanation

Substitute parts for the M3Z68VC are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Zener Voltage (Vz): Nominal value of 68 V
• Power Dissipation: Maximum 200 mW rating
• Impedance: Maximum 200 Ohms
• Reverse Leakage Current: 100 nA @ 51 V
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package: SOD-323F or equivalent SC-90 footprint
• Compliance: ROHS3 compliant, REACH unaffected

The BZT52-B68S_R1_00001 meets all substitution criteria with identical electrical specifications and package compatibility. The tolerance specification differs (±2% versus ±5%), representing an improvement in voltage accuracy that does not restrict substitution.
