Is there a pin-compatible replacement for RS-03K1583FT?

Yes, many 0603 chip resistors are pin-compatible. However, a true 'drop-in' replacement requires identical resistance. Alternatives like RS-03K1623FT match the package but have a slightly different resistance (162kΩ vs 158kΩ) that needs engineering review.

What risks should I check before replacing RS-03K1583FT?

The main risk is the change in resistance value. Ensure your circuit's performance is not adversely affected by the new resistance. Also, verify power rating, temperature coefficient (TCR), and voltage rating are equivalent or better.
