Is there a pin-compatible replacement for PTFR0805B68K0N9?

Yes, several 0805 package resistors are pin-compatible, like TE05G6802BT. However, electrical parameters like TCR and power rating must be carefully verified for your application.

What risks should I check before replacing PTFR0805B68K0N9?

Key risks are performance changes due to weaker precision (tolerance, TCR), different technology (thin vs. thick film), and lower power ratings. Also, verify if AEC-Q200 qualification is required.

Electrical riskhigh

Significant differences in TCR, tolerance, and technology with most candidates.

Package risklow

All candidates share the same 0805 package.

Sourcing riskmedium

Target is a specialized part; alternatives may have different availability.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates require engineering review due to parametric differences, especially in TCR and application qualification.

Best replacement path

For non-automotive use, TE05G6802BT is a possible alternative if a higher TCR (±25ppm/℃) is acceptable. For precision circuits, find a closer TCR match.

Main risk

The main risk is performance degradation in precision circuits due to weaker Temperature Coefficient (TCR) and tolerance in alternatives.

Recommended alternatives

A form-fit 68kΩ 0.1% resistor, but with a higher TCR and slightly lower power rating. Requires review.
