Substitute Part Grouping Explanation

Substitution of the BZX84-A13/LF1R is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

Zener voltage: 13 V nominal
Tolerance: ±1%
Maximum power dissipation: 250 mW
Maximum impedance: 30 Ohms
Reverse leakage current: 100 nA @ 8 V
Forward voltage: 900 mV @ 10 mA

Mechanical & Environmental Parameters (Must Match):

Package type: TO-236-3 / SOT-23-3
Mounting: Surface Mount
Operating temperature range: -65°C to 150°C
Grade: Automotive
Qualification: AEC-Q101
Compliance: ROHS3

The substitute part BZX84-A13,215 meets all specified electrical and mechanical parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.
