How to monitor electronic and mechanical component prices
Monitor public component prices, price breaks and stock at distributors: methods, limits and free tools.
Use manufacturer part numbers
Track the same manufacturer part number across several distributors so you compare like with like. Note the quantity price break you actually buy at.
Price breaks and minimum order quantities
Distributor pages often list several quantity tiers. Compare the tier that matches your order size, not just the single-unit price.
Aggregators and official APIs
Component search engines and distributor APIs can return prices for many parts at once. For a large BOM, these may suit you better than page monitoring.
Page monitoring for your key parts
For a shortlist of critical parts, a page monitor that emails you changes is simple to set up. Check first that each site allows it and shows prices without a login.
This guide is general information, not procurement or legal advice. Check each website鈥檚 terms and robots.txt before monitoring it.
