Substitute Part Grouping Explanation

Substitution of MMBD352WT1 with MMBD352WT1G is based on strict equivalence across all critical electrical and mechanical parameters:

• Diode Configuration: Both parts maintain identical Schottky dual-diode series connection topology
• Voltage Rating: Peak reverse voltage specification of 7V is identical
• Capacitance Characteristics: Capacitance at 0V, 1MHz remains 1pF
• Power Dissipation: Maximum power dissipation of 200 mW is unchanged
• Temperature Range: Operating temperature range -55°C to 150°C (TJ) is identical
• Package Compatibility: Both use SC-70 (SOT-323) surface-mount package with SC-70-3 supplier designation
• Moisture Sensitivity: MSL rating of 1 (Unlimited) is identical

The primary distinction is product lifecycle status: MMBD352WT1 is obsolete, while MMBD352WT1G maintains active status with improved RoHS3 compliance.
