Paste the part numbers from your list, any brand. Each one comes back with its catalog description, its ratings and a link to the catalog page it came from. Numbers that won't order as written come back with the closest match, and anything that could hold up the order gets flagged.
One per line, with the brand if you know it.
Each part number on your list is looked up in its own catalog data. It comes back with its description, its ratings and a link to the catalog page it came from. Only the parts that need your attention get a flag, and there are three. Every other line comes back clean.
The part may not be on a distributor's shelf when you need it. The reason is written on the line: stock was short, the brand builds it to order, or the number adds factory options (like a shunt trip built into a breaker) that we read off the catalog's ordering chart. An alternate is listed beside it where one fits.
The brand has discontinued the part or replaced the whole product line. The note names the published successor, or says none is published. A part that's being phased down but is still sold gets a note, not this flag.
Usually a typo, a missing coil voltage or a missing option digit, or options the catalog's ordering chart says can't go together. The closest catalog match comes back for you to confirm, for example "did you mean ... with a 120 V AC coil?", or the catalog's own reason.
Flagged lines also go on a short Watch List at the top of the document, so the parts that could hold up the schedule are all in one place. Where the catalog prints a caution about a part, like an option that affects the UL rating, it's noted on that part's line.
When a part is flagged, the closest equivalent sits beside it. Your part stays on the list, and the alternate is there if you need it.
Assembled parts like a reversing contactor can also come back as components: two contactors, the interlock and the wiring kit, each checked for stock. It's offered when the brand publishes the kit and the catalog confirms its UL listing.

Confirm on the catalog data:
From one card, your team can see the larger frame covers the motor and approve the swap, or keep the original and plan around the lead time.
"Prefer these" on the form uses your brands wherever they make the part, and marks any alternate from another brand. "Only these" holds every part and every alternate to the brands you pick.
Paste them here and see what each number is, straight from the catalogs. Or attach your parts list as an Excel or CSV file. Then add your email so we can send the results back.
Every number checked against the catalog, stock checked, and alternates written up.
Flags, alternates and anything we need to confirm. If there's a panel behind it, we can quote that too.
Parts checks are matched against published catalog data. Stock information comes from a few distributor sources that publish it; it is a point-in-time check on the day of the review, and stock moves daily. A Lead time flag means confirm availability with your distributor before ordering. Confirm on the catalog data, and with your engineer, before ordering or changing a design.
