AI replacement insight

Package riskmedium

Several candidates have different packages (1206, 0603) and are not drop-in replacements.

Electrical risklow

Many candidates match or exceed key electrical specs. Check resistance value carefully.

Can it be replaced directly?

Yes, 0805W8F6800T5E is a direct replacement with improved performance, and RC0805FR-07680RL is a likely candidate pending power rating verification.

Best replacement path

Upgrade to a 1% tolerance part like 0805W8F6800T5E for better precision in the same 0805 footprint.

Main risk

The main risk is selecting a part with a different package size (e.g., 1206 or 0603) or a different resistance value, which would require design changes.

Recommended alternatives

A pin-compatible upgrade with improved tolerance and temperature coefficient.
