Choosing replacement parts for semiconductor pcb manufacturing is rarely as simple as matching a part number. You might need a vacuum gauge to monitor chamber pressure, a diffuser to support CVD deposition, or a probe positioner for manual probing-and each piece of used equipment carries its own trade-offs. The four listings here range in listed price from $138 to $300, so the decision is not just about what you need, but also about which listing gives you the most useful configuration for your process.
Quick Take
The set includes two listings for the same Applied Materials 0190-09901 Pirani process vacuum analog gauge, one Applied Materials SiCoNi diffuser, and one Micromanipulator 550 right-hand probe positioner. The gauge listings share the same AMAT brand, Used condition, and United States origin, while the diffuser is presented as CVD wafer processing equipment and the probe positioner offers a 100 TPI fine-adjustment mechanism. Your choice should be driven by the process step you are equipping: vacuum measurement, CVD gas distribution, or probing.

Product Notes
0190-09901, Applied Materials, Pirani Process Vacuum Analog Gauge (first listing)
This first listing for the 0190-09901 carries the Applied Materials Pirani process vacuum analog gauge label under the AMAT brand. It is listed as Used and built in the United States. The concrete reason to choose it is that it gives you a straightforward analog Pirani gauge for measuring vacuum levels in semiconductor pcb manufacturing, which is a solid fit if your existing equipment uses analog instrumentation. The limitation is that the unit is pre-owned, so you are not buying new equipment. Its attributes center on the analog gauge function.
0190-09901, Applied Materials, Pirani Process Vacuum Analog Gauge (second listing)
This second listing matches the same 0190-09901 Pirani process vacuum analog gauge title, brand, Used condition, and United States origin as the first. The concrete reason to keep it in view is that it offers a second reference for the exact same part number, which can be useful when you are comparing how the same gauge is offered across different listings. The limitation is that there is no difference in the title, brand, condition, or origin; you are looking at the same analog instrument with the same used status and the same origin.
0022-07853 Applied Materials SiCoNi Diffuser
The 0022-07853 SiCoNi Diffuser from Applied Materials is listed as a piece of wafer processing equipment used in CVD technology. The concrete reason to choose it is the specific pairing with CVD deposition: if your process includes a SiCoNi-related step, this diffuser is aligned to that equipment type. The limitation is that it is listed as Used, so the diffuser carries pre-owned status. Its CVD role is the main factor for evaluation.
The Micromanipulator 550 Right Hand Vacuum Based 100 TPI Xyz Probé Positioner
The Micromanipulator 550 Right Hand Vacuum Based 100 TPI Xyz Probé Positioner comes from The Micromanipulator Co. in the United States. The concrete reason to choose it is the 100 TPI adjustment pitch, which provides fine manual positioning for probing tasks, and the right-hand design that suits that working setup. The limitation is the listed condition: Used with cosmetic wear, so the unit is not cosmetically fresh. The listing specifies a unit quantity of 1 and identifies the probe type as a micro manipulator probe, giving you a clear, purpose-specific component for semiconductor pcb manufacturing probing.
Final Recommendation by Use Case
If your immediate need is monitoring vacuum levels in an analog-friendly line, the first listing of the 0190-09901 Pirani gauge is the direct match. If your process is centered on CVD wafer processing, the 0022-07853 SiCoNi diffuser is the component tied to that technology. For manual, right-hand probing with fine control, the Micromanipulator 550 is the purpose-built pick. The second gauge listing is an alternative reference for the same part number, but it does not add a different configuration from the first.
