Alternative Part Number

  • MF-R250 --: Resettable PTC fuse with similar 2.5A hold current and 30V rating, widely used as a drop-in replacement for SMD250-2.
  • 0ZCG0250FF2B --: Surface-mount polymer PTC with comparable hold current and voltage rating, suitable alternative with different series naming.
  • RUEF250 --: Radial-leaded resettable PTC with matching 2.5A hold current; feasible if through-hole mounting is acceptable.
  • MF-MSMF250/16X-2 --: PTC resettable fuse with 2.5A hold current and 16V rating, functionally equivalent to the SMD250-2 in a similar 1812 SMD package.
  • 1812L250/16MR --: 2.5A hold current resettable PTC fuse in 1812 SMD form factor, a direct functional replacement for the SMD250-2.
  • 0ZRM0250FF1E --: Radial polymer PTC resettable fuse rated around 2.5A hold current, offering similar trip characteristics and a well-established alternative supply source.
  • RXEF250 --: Radial PPTC resettable fuse with 2.5A hold current and similar electrical behavior, suitable as a functional replacement when layout allows leaded parts.
  • MF-MSMF250-2 --: Bourns Multifuse PTC resettable fuse with similar 2.5A hold current rating and 1812 SMD footprint, a well-established cross-reference for Raychem SMD250-2.
  • 0ZCG0250FF2E --: Bel Fuse 0ZCG series SMD PTC resettable fuse rated around 2.5A hold current, suitable drop-in replacement with comparable voltage and trip characteristics.
  • LVR025S --: Littelfuse PolySwitch-compatible radial PTC resettable fuse with 2.5A hold current; usable alternative when layout allows through-hole mounting.
