From the same manufacturer, FRC0402F1004TS is an upgrade path with a tighter ±1% tolerance.
FRC0402J105 TS is a general-purpose 1MΩ 5% 0402 chip resistor from FOJAN. Multiple alternatives are available, including direct cross-vendor replacements and upgrades with tighter tolerance or automotive-grade reliability.
Most alternatives are upgrades (tighter tolerance/TCR), which is generally safe for resistor applications.
All recommended alternatives are in the standard 0402 package, ensuring physical compatibility.
Switching from FOJAN to a different manufacturer like Yageo requires updating the Approved Vendor List (AVL).
Direct replacement for FRC0402J105 TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For a like-for-like replacement, use Yageo RC0402JR-071ML. For a simple upgrade from the same brand, use FOJAN FRC0402F1004TS.
The primary risk is minimal and relates to vendor qualification, as many alternatives are direct upgrades in tolerance or reliability (AEC-Q200).
