Is there a pin-compatible replacement for FRC0402F6800TS?

No, due to a strict engineering rule requiring a higher power rating (≥1.5x), no pin-compatible 0402 replacements were identified. All viable options are in larger packages.

What risks should I check before replacing FRC0402F6800TS?

The main risk is the physical package size. All recommended substitutes are larger (0603 or 0805) and will not fit on the original 0402 footprint, requiring a PCB redesign.

FRC0402F6800TS Alternatives, Datasheet & Cross Reference | FOJAN

Find functional alternatives for the FRC0402F6800TS, a 680Ω 1% 0402 chip resistor. While no direct drop-in replacements meet strict power safety margins, several options in larger packages offer improved performance.

AI replacement insight

Package riskhigh

All suggested alternatives require a PCB layout change from 0402 to 0603 or 0805.

Electrical risklow

Key electrical parameters (resistance, tolerance, TCR) match, and power rating is improved.

Can it be replaced directly?

No direct pin-to-pin replacements were found that meet the required engineering safety rule for power rating (≥1.5x target). All same-package (0402) candidates had insufficient power ratings.

Best replacement path

Use a 680Ω 1% resistor in a larger 0603 package, such as FRC0603F6800TS or 0603WAF6800T5E. This provides a higher power rating and meets engineering safety margins, but requires a PCB layout modification.

Main risk

The primary risk is the package mismatch. All viable alternatives are in larger packages (0603 or 0805), which are not drop-in replacements and require a new PCB layout.

Recommended alternatives

Functional alternative with same resistance and tolerance but in a larger 0603 package with higher power rating.
