FOJAN
A strong pin-compatible alternative with nearly identical electrical characteristics and technology.
RS-03K6201FT is a general-purpose 6.2kΩ 1% 0603 thick film resistor. Several pin-compatible replacements are available, including direct matches and precision upgrades that require minor engineering review.
All suggested alternatives are in the same 0603 package.
Switching from thick film to thin film technology can affect pulse withstanding capability. This requires engineering review.
6.2kΩ 0603 resistors are widely available from multiple manufacturers.
Direct replacement for RS-03K6201FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For a direct, low-risk replacement, FRC0603F6191TS is the best option. For a precision upgrade, consider RT0603BRD076K2L, but validate the technology change.
The primary risk is substituting a thin film resistor for the original thick film part without verifying its suitability for the application's pulse or surge conditions.
