The individual parts that circuits are built from, in through-hole packages for breadboards and stripboard, plus common SMD parts. Popular here are the BC547 and 2N2222 transistors, IRLZ44N and IRFZ44N MOSFETs, L7805 and AMS1117 voltage regulators, the NE555 timer and the LM741 op-amp.
Choosing parts
Match the part number from your schematic first: a datasheet value such as voltage, current or pinout is what matters, not the brand. When switching a load from an Arduino or ESP32, pick a logic-level MOSFET (IRLZ44N, IRLB8721) that turns fully on at 5V or 3.3V. Browse transistors, MOSFETs, voltage regulators, op-amps, logic gates and audio amplifier ICs.
