UNI-ROYAL
UNI-ROYAL 0603WAF1201T5E is the closest same-vendor 0603 1.2k candidate.
0603WAJ0122T5E is a 0603 1.2k thick-film chip resistor. The closest candidates keep the same 0603 size and 1.2k value, but still need FAE review.
same 0.1W rating needs margin check
top candidates are 0603
passive resistor
cross-vendor parts need approval
Direct replacement for 0603WAJ0122T5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Prefer same 0603, 2-terminal, 1.2k parts with equal or tighter tolerance and verified 0.1W, 75V, and temp ratings.
Power derating and PDF review are still open.
