Substitute Part Grouping Explanation

Substitution for the MJD2873-13 is determined strictly by matching the key electrical and mechanical parameters stipulated for this product category. A substitute part must have identical or compatible specifications for transistor type, maximum collector current, breakdown voltage, saturation voltage, cutoff current, DC current gain, maximum power dissipation, transition frequency, operating temperature range, mounting type, package/case, RoHS and REACH status, and product life cycle status. Only components that precisely match these attributes are considered valid parametric equivalents.
