Is there a pin-compatible replacement for SMD0805P100TF?

TLC-PSMD100 and SMD0805-100C-12V are strong candidates for pin-compatible replacement as they share the 0805 package. However, always verify the full datasheet specifications, especially trip characteristics and resistance, against your application's requirements before implementation.

Q: What risks should I check before replacing SMD0805P100TF?

Before replacing SMD0805P100TF, check the hold current (must be 1A), trip current (should be ~2A), and max voltage (≥6V). Using a part with a higher hold current will compromise circuit protection. Also verify the time-to-trip and resistance values to ensure they are compatible with your design.

RUILON's SMD0805P100TF is a 1A, 6V resettable PTC fuse in an 0805 package, commonly used for overcurrent protection. When seeking alternatives, prioritize matching the 1A hold current and 0805 package size.
