That means no last-time-buy window is open, and the part is still in regular production. For a BOM freeze or a new design, this part does not carry the obsolescence risk that some older high-speed op-amps do. The ROHS3 compliance is current, so it passes European and Asian environmental requirements without a waiver.
The active status means the supply channel is stable.
The ADA4851-1WYRJZ-R7 from Analog Devices is a voltage-feedback op-amp in a similar speed class — 375 V/µs slew rate, 105 MHz bandwidth, rail-to-rail output, and automotive temperature range. It is not a pin-for-pin drop-in (different package options), but it covers the same high-speed single-supply signal-chain role. Check the pinout and layout before substituting.
It comes in a TSOT-23-6 (thin SOT-23-6) package for surface-mount assembly. The supplier device package is TSOT-23-6. It is available in Tape & Reel or Cut Tape options.
