FOJAN
An upgrade path from Fojan, offering a tighter ±1% tolerance in the same 1206 package.
FRC1206J184 TS is a common 180kΩ 5% 1206 chip resistor from FOJAN. Several pin-compatible upgrades with tighter tolerance are available from multiple vendors.
Candidates match key electricals or offer a safe upgrade (tighter tolerance).
Recommended substitutes share the same 1206 package for drop-in compatibility.
Direct replacement for FRC1206J184 TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a 1% tolerance version like Yageo's RC1206FR-07180KL or FOJAN's FRC1206F1803TS for a direct, improved-precision replacement.
The main risk is minimal, as replacements offer tighter tolerance. Ensure power rating and temperature characteristics are sufficient.
