What is the difference between LM358DR and LM358DGKR, LM358P, LM358PWR?
These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — LM358DGKR: Package/pins: VSSOP (DGK), 8 pins; LM358DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinoutt.; LM358P: Package/pins: PDIP (P), 8 pins; LM358DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is TUBE, 50 per pack; LM358DR is LARGE T&R, 2,500 per pack.; LM358PWR: Package/pins: TSSOP (PW), 8 pins; LM358DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 2,000 per pack; LM358DR is LARGE T&R, 2,500 per pack.. LM358DR itself is the SOIC-8 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
