Compatible Replacement & Equivalent Models
The following part numbers are known cross-references or functional equivalents for the 0040-44504 manifold valve assembly:
- 0050-53743 — Applied Materials alternate assembly P/N (same form/fit/function)
- MFA050HA5NSD — OEM sub-assembly designation used in BOM documentation
- Generic 8-way pneumatic manifold assemblies rated for semiconductor-grade process gas service may serve as field replacements pending engineering approval
Always verify dimensional, pressure, and media compatibility before substituting parts in a live process tool.
Why Choose the Original Model
- Process Integrity: OEM-spec sealing materials and flow coefficients maintain process repeatability on MDX-10K tools
- Traceability: Full lot and serial traceability for SEMI S2/S8 compliance audits
- Drop-in Fit: Exact bolt pattern and port configuration — no re-engineering required
- Validated Performance: Factory-tested to Applied Materials internal acceptance criteria
Typical Applications
- CVD (Chemical Vapor Deposition) gas distribution manifolds
- Etch tool process gas switching
- Vacuum and purge line valve banks on MDX-10K platforms
- Semiconductor fab maintenance and spare-parts inventory programs
System Compatibility
- Primary Platform: Applied Materials MDX-10K
- Potential Cross-Platform Use: Other Applied Materials platforms using MFA050-series manifold assemblies (verify with engineering before installation)
- Media Compatibility: Process gases and inert purge gases standard to semiconductor CVD/etch environments (confirm wetted-material compatibility for corrosive chemistries)

Replacement & Compatibility FAQ
Q: Is 0050-53743 a direct replacement for 0040-44504?
A: Yes. Both part numbers refer to the same 8-way manifold valve assembly; 0050-53743 is the updated BOM reference for the same physical part.
Q: Can this manifold be used on platforms other than the MDX-10K?
A: Potentially, if the port configuration and process media are compatible. Always consult your process engineer before cross-platform installation.
Q: Do you offer refurbished units?
A: Yes. Refurbished units are available at reduced cost and include full functional testing and a 90-day warranty. Specify condition preference when ordering.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock units typically have a 2–6 week lead time depending on sourcing channel.
