Description

Applied Materials 0190-37684 | MKS CDN494R Controller PCB | Semiconductor Equipment

Key Technical Specifications

The strongest available cross-reference evidence identifies 0190-37684 with MKS CDN494R and AS02494-AB-1. Other equipment-part records also associate it with 0100-09068, IS5413-00, and 800-5830-4R as a mini-controller assembly.

Because these are equipment-level semiconductor control assemblies rather than standardized PLC modules, specifications such as supply voltage, channel count, processor type, memory, and communication protocol should not be inferred from unrelated listings. One listing describes the part as an I/O PCB, while another identifies the same cross-reference group as a mini-controller assembly; that difference is best resolved using the board label, revision, and Applied Materials equipment BOM.

Product Introduction

The Applied Materials 0190-37684 is a specialized semiconductor-equipment control PCB associated with the MKS CDN494R / AS02494-AB-1 architecture. Available equipment records also cross-reference it with 0100-09068, IS5413-00, and 800-5830-4R, indicating that the part appears at the assembly level under different Applied Materials and MKS identifiers.

For maintenance purposes, this should be treated as an equipment-specific controller/interface board, not as a generic analog or digital I/O module. The exact board revision and host tool configuration matter because semiconductor processing equipment often uses tightly matched controller hardware, firmware, backplane connections, and subsystem configuration.

Application Scenarios & Field Pitfalls — Engineer’s Perspective

Engineering Pain Point

A failed 0190-37684 can produce communication, subsystem-control, or I/O-related faults at the equipment level. The practical difficulty is that a board-level failure can look like a sensor, actuator, cabling, or software configuration problem, particularly when several signals disappear simultaneously.

Typical Applications

• Applied Materials semiconductor wafer-processing equipment
• CVD/PVD process-control subsystems
• Equipment control racks using MKS CDN494R architecture
• Legacy semiconductor-tool maintenance and spare-parts replacement

The available equipment records associate the part with Applied Materials CVD/PVD equipment and identify the /AS02494-AB-1 architecture.

Technical Pitfalls to Avoid

1. Do not automatically identify 0190-37684 as an RF matching network.
   One secondary listing describes it as an RF automatic matching module, but other records consistently identify 0190-37684 as an MKS / AS02494-AB-1 PCB. That conflict is significant enough that RF specifications should not be published as verified facts for this part.
2. Do not assume it is a standalone generic I/O card.
   The same part number is cross-referenced to a mini-controller assembly containing the architecture. Its actual function depends on the Applied Materials equipment configuration in which it is installed.
3. Match the PCB revision, not just 0190-37684.
   A documented market example identifies 0190-37684 with MKS and AS02494-AB-1, while another listing identifies a specific board. Revision differences should be checked before assuming interchangeability.
4. Verify the complete cross-reference against the equipment BOM.
   The 0100-09068 / 0190-37684 / / IS5413-00 / 800-5830-4R grouping appears repeatedly, but these identifiers may describe different assembly levels or equipment revisions. Do not substitute solely from a reseller cross-reference.

Procurement Check

Before approving an Applied Materials 0190-37684 replacement, verify:

• Exact part number: 0190-37684
• Board manufacturer marking
• marking, if present
• cross-reference
• PCB revision
• Applied Materials equipment model
• Equipment BOM/service-manual reference
• Assembly-level number, if applicable
• Connector arrangement
• Backplane/interface configuration
• Firmware or configuration requirements
• Existing board jumper/switch settings, if fitted
• ESD and contamination-control requirements
• Physical condition of edge connectors and PCB
• Whether the required item is the bare PCB or complete mini-controller assembly

The key point is that 0190-37684 should be purchased by exact board identity and host-equipment configuration, not by a generic description such as “RF matcher” or “vacuum controller.” The strongest cross-reference evidence supports the MKS / controller-board identification, while detailed electrical specifications remain revision- and equipment-dependent.
