Package type LH is a modified SOT23W surface-mount package that switches with magnetic fields oriented perpendicularly to the non-leaded side of the package. The UA package is an ultra-mini SIP, equipped for through-hole mounting and lead forming, that switches when a magnetic field is presented to the top of the package, parallel with the branded face. Both packages are RoHS-compliant and lead (Pb) free (suffix, -T), with 100% matte-tin-plated leadframes.
