Pin-compatible high-voltage resistor with a significantly higher voltage rating.
Find pin-compatible and upgrade path alternatives for the UNI-ROYAL 1206W4J0106T5E, a 10MΩ 5% 0.25W 1206 thick film resistor. Review key parametric differences before substitution.
Low for pin-compatible parts. Medium for technology change.
None for candidates with matching 1206 package.
Yes, several manufacturers offer direct replacements. The key is matching the 1206 package, 10MΩ resistance, 5% tolerance, and 0.25W power.
Use a pin-compatible thick film resistor like FRC1206J106 TS for a direct swap-in.
The main risk is substituting with a part that has a different technology (e.g., thin film) or a wider temperature coefficient (TCR) without verifying application impact.
