OP27 replacement: the OP37, OPA227, AD797 and AD8671 options compared
The OP27 precision op-amp is NRND at ADI. The deciding difference is compensation, worked out part by part.
TLP250 replacement: the HCPL-3120, TLP352 and gate-driver optocoupler options compared
The Toshiba TLP250 gate-driver optocoupler is obsolete, and every still-made cross drives more current and adds UVLO.
MCP2551 replacement: the MCP2561, SN65HVD230 and SN65HVD251 crosses compared
The Microchip MCP2551 is obsolete in SOIC-8. Three active crosses, none a drop-in, worked out pin by pin.
