Temperature grade and environment
Rated from -40°C to 150°C, this transceiver lives where standard commercial parts do not. That full range covers cold cranking and hot-soak under the hood. The AEC-Q100 qualification is the automotive industry's reliability baseline — stress-tested for high-temperature operating life, ESD, and latch-up. For a field-service swap, the exposed pad needs a hot-air station or a reflow oven; this is not a hand-solder part with a standard iron.
Lifecycle and sourcing
Infineon lists the TLE8457BLEXUMA1 as Active and ROHS3 compliant. No NRND or EOL notice on record. It is a current-production part, so no last-time-buy scramble. For BOM planning, this is a straight-line procurement item — no obsolescence risk in the near term. We source and quote it to order through independent distribution; availability and current pricing are confirmed at quote time.
