Substitute Part Grouping Explanation

Substitute parts for the BZX84W-B2V7F are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

Nominal Zener voltage: 2.7 V
Voltage tolerance: ±2%
Maximum power dissipation: 275 mW
Maximum impedance: 100 Ohms
Reverse leakage current: 20 µA @ 1 V
Forward voltage: 900 mV @ 10 mA
Operating temperature range: 150°C (TJ)
Package type: SOT-323 (SC-70)
Mounting configuration: Surface Mount

All substitute parts must maintain identical electrical performance within the specified tolerances and operate within the same thermal and mechanical constraints. Compliance certifications (ROHS3, REACH Unaffected) and moisture sensitivity ratings must remain consistent.
