Substitute Part Grouping Explanation

Substitution for 2SC4536-AZ is determined strictly by comparing the following allowed parameters: transistor type (NPN), collector-emitter breakdown voltage (Vce max), maximum collector current (Ic max), maximum power, noise figure (at specified frequency), gain, DC current gain (hFE) at specified test conditions, operating temperature, mounting type, package/case, supplier device package, compliance statuses (REACH, MSL, ECCN), and product status. Only parts matching or exceeding these specifications and within the same surface mount category are considered suitable substitutes.
