Package risklow

All viable candidates use the same 2512 package.

Sourcing risklow

This is a common resistor value available from multiple vendors.

Can it be replaced directly?

Direct replacement for FRC2512F1R50TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Upgrade to RC2512FK-7W1R5L for higher power handling and better thermal stability.

Main risk

The main risk is using a part with a different nominal resistance or an unknown Temperature Coefficient (TCR), which can affect circuit performance and stability.

Recommended alternatives

Upgrade with double the power rating (2W) and improved temperature coefficient.
