50 sections, 564,344 parts. Categories marked parametric let you filter by value, case size and availability instead of starting from a part number.
TracedParts holds 564,344 electronic component part numbers from 2,509 manufacturers, filed in 1,006 categories following the distributors’ own category tree. Every price and stock figure is pulled from DigiKey, Mouser or element14 through their published APIs, most recently on 2026-09-25, and each part page names the distributor that supplied it.
MCUs, MPUs and the boards-worth of flash and RAM that come with them. Filter by core, clock and package once you know roughly what you need.
Fixed and adjustable LDOs and classic three-terminal regulators, from 150 mA SOT-23 parts up to 1.5 A in TO-220.
Switching regulators for when a linear part would cook. Step-down converters rated 3 A across the usual input ranges.
General-purpose bipolar and JFET operational amplifiers plus the comparators that usually sit next to them.
The 555 and its relatives, in both through-hole and surface-mount packages. Still the cheapest way to make a pulse.
ADCs and DACs with SPI and I2C interfaces, 10 to 16 bits, for reading the analog world into a microcontroller.
Shift registers, bus transceivers and analog multiplexers from the 74HC and CD4000 families.
Rectifiers, switching and Schottky diodes, bipolar transistors and power MOSFETs. The parts you buy by the thousand.
Wi-Fi and Bluetooth modules and 2.4 GHz transceivers, pre-certified so you do not have to run the radio approvals yourself.
Environmental, inertial and temperature sensors with digital interfaces, ready to hang off an I2C or 1-Wire bus.
MLCCs from 22 pF to 22 uF in 0402 through 1206. Filter by capacitance, case size and what is actually in stock.
Thick-film chip resistors, 1% tolerance, 0402 through 1206. Filter by resistance decade, case size and availability.
