UNI-ROYAL
UNI-ROYAL 0805W8F5100T5E is a same-family 0805 510Ω tighter-tolerance option.
0805W8J0511T5E is a UNI-ROYAL 0805 510Ω ±5% thick-film resistor. Several 0805 510Ω candidates look close, but FAE review is needed.
power and voltage margins need check
0805 options align; 1206 does not
passive resistor
cross-vendor approval may be needed
Close 0805 candidates exist, but none should be called verified until PDF and derating checks are complete.
Start with same-package 0805 510Ω parts with equal or tighter tolerance and matching TCR.
Equal 0.125W ratings require application power-margin review.
