Is there a pin-compatible replacement for RTT024702FTH?

Yes, WR04X4702FTL from Walsin Technology Corporation is a pin-compatible replacement. It features the same 0402 package, 47kΩ resistance, ±1% tolerance, and 1/16W power rating.

What risks should I check before replacing RTT024702FTH?

Before replacing, first confirm if your circuit can tolerate any deviation in resistance value, especially if choosing a 'parametric_relaxed' option. Second, if using an upgrade like a thin film resistor, ensure its characteristics (e.g., pulse handling) are suitable for your application.
