Octopart alternatives for comparing part prices and stock

Octopart is where many engineers go to see which distributors have a part and at what price. It is good at that, but it answers one question about one part at a time. Depending on whether you are checking a single chip, pricing a whole BOM or building for JLCPCB assembly, a different tool may fit better.

What Octopart does well

Octopart searches the listings of many authorized distributors at once and shows price breaks, stock and datasheets side by side. It also has a BOM tool and an API (through Nexar, part of the same group as Altium). For "who has this exact part number in stock right now", it is hard to beat.

Where people look for something else: comparing many lines at the quantity a build needs, sources that are not in the results, and turning the comparison into an order.

The alternatives

Tool	Good for	Keep in mind
Findchips (Supplyframe)	The same kind of search as Octopart: one part number, many distributors, price and stock.	Like Octopart, one part at a time unless you use its BOM features.
DigiKey and Mouser search	Parametric search, full price ladders, cut tape vs reel, exact stock.	One distributor each. Same part, two tabs.
JLCPCB / LCSC parts library	Boards JLCPCB assembles: basic vs extended status, stock at the assembly house, low prices on Chinese manufacturers.	Western distributors are not compared.
Your EDA tool's part search	Picking parts with a footprint while you draw the schematic.	Usually shows availability, not a full price comparison.
Next Everything	A whole BOM priced at your board count across JLCPCB/LCSC, DigiKey and Mouser, with problems flagged and alternatives suggested, from your AI assistant.	Covers those three sources today; not a general search engine for every distributor.

Why per-quantity BOM pricing matters

A single-part search shows unit prices. A build pays line totals, with minimums and reels applied. Two examples from 22 October 2026, for 100 pieces:

CP2102N-A02-GQFN28R USB-UART bridge: $1.3408 at JLCPCB with 31,330 in stock; $2.89 at Mouser and $3.3934 on DigiKey cut tape, both with zero stock. DigiKey's reel price was $2.99659, but only in 1,500-piece reels.
ESP32-C3-WROOM-02-N4 module: $2.4347 at JLCPCB, $2.5391 at DigiKey and $2.59 at Mouser at 100 pieces, all in stock. At 650 pieces, DigiKey's reel at $1.90 was cheaper than JLCPCB's $2.3366.

The cheapest source changes with the quantity, and the unit price on a search result can belong to an offer you cannot buy at your quantity. More examples are in our article on minimum order quantities.

Which one to use

One part, who has it: Octopart or Findchips.
Choosing a part by specs: DigiKey or Mouser parametric search, or the JLCPCB library if JLCPCB assembles the board.
A whole BOM, priced for your build: a BOM tool. If you already work with an AI assistant in Claude Code, Cursor or Codex, Next Everything does this from the chat, using the BOM file in your project.

For a real BOM priced at two distributors line by line, see Mouser vs DigiKey on a 48-line BOM.

About the data

The numbers in this article come from Next Everything, an MCP server we build that lets AI assistants such as Claude, Cursor and Codex check a BOM against the JLCPCB/LCSC catalog and live Mouser and DigiKey prices. If you want to run the same check on your own BOM, the setup guides show how to connect it.

Next Everything is not affiliated with Mouser, DigiKey, JLCPCB or LCSC. Prices are list prices in USD at the time stated and change daily.
