FOJAN
Upgrade path with tighter ±1% tolerance in the same 1206 package and power rating.
Find and compare verified substitutes for the FOJAN FRC1206J334 TS, a common 330kΩ 0.25W 1206 chip resistor. Explore pin-compatible upgrades and parametric alternatives to meet your design needs.
Multiple candidates share the same 1206 package, ensuring physical compatibility.
Some candidates have different resistance or missing TCR data, requiring engineering review.
Yes, 1206W4J0334T5E from UNI-ROYAL is a strong candidate with matching key parameters, though its TCR should be verified from the datasheet.
Upgrade to a ±1% tolerance part like FRC1206F3303TS or RS-06K3303FT for better precision at potentially no extra cost.
The primary risk is using a parametric alternative with a different resistance value (e.g., 300kΩ or 360kΩ) without analyzing its impact on circuit performance.
