When you're shopping for a replacement vacuum gauge for semiconductor or PCB manufacturing, finding two listings with the same part number can feel confusing. Both show the Applied Materials Pirani process vacuum analog gauge, part 0190-09901, and both claim the same used condition. The only obvious split is the listed price: one is $199, the other $295. Which one should you choose?
Quick verdict
These two listings are for the identical AMAT part, described the same way: a Pirani process vacuum analog gauge, used condition, made in the United States. With no confirmed difference in specifications, condition, or included accessories, the $199 listing is the straightforward choice. The $295 listing does not bring any extra listed benefit to the table, so the lower price wins.
Side-by-side comparison
| Listing | Listed Price | Price Bar |
|---|---|---|
| 0190-09901, Applied Materials, PIRANI PROCESS VACUUM ANALOG GAUGE (USD 199.00) | USD 199.00 | |
| 0190-09901, Applied Materials, PIRANI PROCESS VACUUM ANALOG GAUGE (USD 295.00) | USD 295.00 |
Both listings share the same brand (AMAT), condition (Used), and country of origin (United States). The only numerical difference is the listed price, a $96 gap.
Where each listing stands
$199 listing - Wins on listed price. You get the same described part for less.
$295 listing - Matches the $199 listing on every confirmed detail. The only difference is the higher listed price, so it does not add anything for the extra cost.
Product notes
0190-09901, Applied Materials, PIRANI PROCESS VACUUM ANALOG GAUGE - $199.00
This listing is the more economical way to get the Applied Materials Pirani process vacuum analog gauge. At USD 199.00, it carries the same brand (AMAT), the same used condition, and the same United States origin as the other listing. If you're looking for this specific AMAT part number, the lower listed price means you're paying less for the same described item. The gauge is listed as used, so it comes with the typical considerations of a pre-owned component. Still, among the two identical listings, this one leaves more money in your budget.
0190-09901, Applied Materials, PIRANI PROCESS VACUUM ANALOG GAUGE - $295.00
This listing shows the same AMAT Pirani process vacuum analog gauge at USD 295.00. It matches the $199 listing on the title, description, brand, condition, and country of origin. When compared directly, the only difference is the listed price: $295 versus $199. The higher price is a limitation because you are paying more for the same described used gauge. Because the two listings are otherwise identical, this one makes sense only if the lower-priced listing is unavailable.
Final choice by use case
If you need an AMAT Pirani process vacuum analog gauge and want to keep your spending in check, the $199 listing is the pick. It gives you the same part number, same brand, same used condition, and same origin as the $295 listing, but at a lower listed price. If you're managing a semiconductor or PCB manufacturing line and every dollar counts, the cheaper listing lets you acquire the same specified gauge without paying extra. The $295 listing is only relevant if the lower-priced one disappears, since it offers no confirmed advantage.
