Substitute Part Grouping Explanation

Substitution of the BZX84J-C13,115 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Zener voltage: 13 V nominal
• Maximum power dissipation: 550 mW
• Impedance (Max): 10 Ohms
• Reverse leakage current: 100 nA @ 8 V
• Forward voltage: 1.1 V @ 100 mA
• Operating temperature range: -65°C to 150°C

Mechanical & Compliance Requirements:

• Package: SOD-323F (SC-90)
• Mounting: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS3 Compliance
• MSL: 1 (Unlimited)

The BZX84J-B13,115 qualifies as a parametric equivalent substitute. While the tolerance specification differs (±2% versus ±5%), all other electrical parameters, thermal characteristics, package specifications, and automotive qualifications remain identical. The tighter tolerance of the substitute part does not preclude its use in applications designed for the primary part.

Parameter Comparison
