What risks should I check before replacing FRC1210F3R30TS?

Before replacing, verify that the alternative's secondary parameters, like Temperature Coefficient (TCR) and pulse withstanding capability, are suitable for your design. If considering a parametric alternative like AC1210FR-073RL, you must confirm your circuit can tolerate the different resistance value (3.0Ω vs 3.3Ω).
