FOJAN
A 300kΩ resistor in the same 1206 package, but with a wider ±5% tolerance compared to the target's ±1%.
RS-06K3003FT is a precision thick film chip resistor from FH, offering 300kΩ resistance with a tight ±1% tolerance in a standard 1206 package. It is rated for 0.25W power with a TCR of ±100ppm/℃.
Tolerance or resistance value changes will impact performance in precision circuits like dividers, filters, or gain stages.
All candidates use the same 1206 surface-mount package, ensuring physical compatibility.
There are no direct, 1-to-1 replacements for RS-06K3003FT among the candidates reviewed. All proposed alternatives have parametric differences requiring engineering evaluation.
No direct drop-in replacement was found. Alternatives require a trade-off: either accept a wider ±5% tolerance or a ±10% deviation in resistance value.
The primary risk is a change in circuit behavior due to either lower precision (±5% tolerance) or a shifted resistance value (±10%).

The best alternative depends on your circuit's needs. If maintaining ±1% precision is critical, consider parts like RC1206FR-07270KL (270kΩ) and verify if the resistance shift is acceptable. If the 300kΩ value is more important, FRC1206J304 TS is an option, but it has a wider ±5% tolerance.
