Is there a pin-compatible replacement for 0805W8J0151T5E?

Yes, several candidates like RC0805JR-07150RL and RT0805BRD07150RL share the same 0805 package and pinout. However, they have different electrical characteristics (TCR, technology) and are not considered direct drop-in replacements without review.

What risks should I check before replacing 0805W8J0151T5E?

Before replacing, check three main risks: 1) Technology change from Thick Film to Thin Film, which can affect pulse handling. 2) Weaker Temperature Coefficient (TCR), which impacts stability. 3) Power rating, as none of the candidates meet the conservative 1.5x safety margin.
