UNI-ROYAL
Same-series 5.1Ω 1206 candidate with tighter tolerance; FAE review required.
1206W4J051JT5E is a 5.1Ω ±5% 1206 thick-film resistor. Same-value 1206 candidates exist, but PDF and power checks are still required.

cross-vendor approvals may differ
Direct replacement for 1206W4J051JT5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with 1206W4F510KT5E, then review Yageo RC1206FR-075R1L as a cross-vendor option.
Equal 0.25W rating leaves no added derating margin.
