What risks should I check before replacing 0805W8F3402T5E?

When substituting, primarily check for resistance and tolerance deviations. For parametric alternatives, ensure the different resistance value is acceptable. For any cross-vendor part, also verify secondary parameters like temperature coefficient (TCR) and voltage ratings from the datasheet.
