Finding Cross References
From the home screen, select Find Cross References in the tab bar, then type a part number into the search bar and press Enter.
Wizerr supports the following input methods:
Single part number — type one part number and search
Multiple part numbers — add parts one by one to search for crosses across all of them simultaneously
Upload a CSV — click the paperclip icon in the search bar to upload a list of part numbers (e.g. from a BOM)
Upload a datasheet PDF — click the paperclip icon to upload a datasheet for parts not yet in the Wizerr database
For supported component categories, see Categories Supported for Cross Reference.
Reading the Results Table
Results are grouped and ranked by match quality. Each row shows:
Match Type — DROP-IN, FORM AND FIT, or ALTERNATE (see below)
Match Score — 0 to 1, where 1.00 is the closest match
Manufacturer, Overview, Description, Status, Type and additional technical columns
Scroll horizontally to view additional columns. Use Columns in the top right to show or hide specific fields.
Match types
DROP-IN — Confirmed physical and electrical replacement. Package, pin count, pin function, and electrical parameters all match to a high degree.
FORM AND FIT — Fits physically on the board but requires pin function and electrical parameter verification before use.
ALTERNATE — May be electrically similar but does not physically fit the same board location. Requires design review.
Refine Search
Click Refine Search to narrow results by specific parameters such as supply voltage, current, number of channels, and more. Wizerr can suggest values automatically based on the reference part, or you can set your own. Click Run Search to apply.
Pricing & Procurement
Click the $ icon on any result row to open the Procurement Information panel, showing:
Part lifecycle status and compliance
Real-time pricing, inventory, MOQ, and factory lead times across multiple distributors
You can also ask the Chat panel for pricing — e.g. "pricing for LTC4211CMS8#PBF".
Compare Datasheets
Click the Compare Datasheets icon on any row to open a side-by-side PDF comparison view — useful for analyzing differences between the reference part and a candidate replacement.
Chat
Click Chat in the top right to open the AI chat panel. Ask engineering questions about any part in the results. Use @ followed by a part number to reference a specific component.
