BSMD1812-300-24V is a same-package PPTC candidate with higher voltage rating.
BSMD1812-300-16V alternatives should keep the 1812 PPTC form, 3A hold current, 6A trip current, and adequate voltage rating. Current and trip behavior are the main review items.
R and trip curves may differ.
1812 is listed for kept candidates.
Passive protection part.
Use catalog status and lifecycle checks.
Direct replacement for BSMD1812-300-16V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Review BSMD1812-300-24V first; it is same-family 1812 with matched current and higher voltage.
Trip curve, resistance, and footprint details are not PDF-checked.
