Package and mounting — what the 8-SOIC means for the board
The 8-SOIC (0.154" body width, 3.90 mm) is a standard surface-mount footprint. The supplier device package is listed as 8-SO. Tape & Reel (TR) and Cut Tape (CT) options are available from the distributor. No special thermal management is needed at the 10 mA output current; the 1.5 mA quiescent current keeps self-heating negligible. For a panel retrofit where the original design used a through-hole reference, a small adapter board is required — the 8-SOIC won't drop into a DIP socket.
Lifecycle and compliance — active and RoHS3
The LT1019CS8-10#TRPBF carries an Active product status, so there is no last-time-buy or obsolescence risk for new designs. It is ROHS3 compliant, which covers the EU RoHS exemption list. No REACH or UL documentation is cited in the available data; the buyer should request the manufacturer's declaration of compliance from the distributor if those are required for the end-equipment certification file.
