A clear parts list saves days of back-and-forth. Suppliers quote faster when they do not have to guess. This guide lists what to include and why.
A: an incomplete list. The supplier has to ask, often more than once. B: a complete list gets a quote on the first pass.
Start with complete part numbers
Use the full manufacturer part number, including every suffix. Suffixes often set the package, temperature grade or packaging.
Two parts can share a base number but differ in package or reel size. A short number forces the supplier to ask, or to guess.
1 Base part number. 2 Package code: D is SOIC-8 for this part. 3 Packaging code: R is tape and reel. Suffix meanings differ between manufacturers, so check the datasheet.
- Copy part numbers from the datasheet or your approved vendor list.
- Put the manufacturer name in its own column.
- Keep one part per row.
Give real quantities
State the quantity you need now. If you plan later orders, add them in a separate column.
Prices often change with quantity. A realistic number gets you a realistic price.
List approved alternates
If your design allows second sources, say so. Add the alternate part numbers your engineers have approved.
Alternates widen the search. They can shorten lead times when the first choice is hard to find.
Say what you need on arrival
- Packaging: full reel, cut tape, tray or tube.
- Date code: any limit, such as "2024 or newer".
- Compliance: RoHS or other rules your customers set.
- Documents: any paperwork your quality team needs with the goods.
Add your timing and budget
Tell us when the parts must arrive. "As soon as possible" and "within one month" lead to different options.
If you have a target price, include it. It helps us focus on sources that fit your budget.
Use a format that is easy to read
A spreadsheet or CSV file works best. Use one header row and avoid merged cells.
Columns: 1 part number, 2 manufacturer, 3 quantity, 4 packaging, 5 date code limit, 6 needed by. The first row leaves the supplier guessing. Example data.
| Column | Example |
|---|---|
| Part number | Full number with every suffix |
| Manufacturer | Brand name |
| Quantity | Units needed now |
| Alternates | Approved second sources |
| Packaging | Reel, cut tape, tray or tube |
| Date code limit | 2024 or newer |
| Needed by | Target arrival date |
Send it with your request
Attach your list to the quote request form. It accepts spreadsheets, CSV, PDF and images up to 10 MB.
Our quote states the quantity, date code, packaging and lead time for each line we can supply.
