Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the Brooks 5964-EP in CF4 service:
- Brooks 5850E / 5850S – Same series predecessor; direct pin-compatible in many installations
- Brooks 5964-E – Standard (non-EP) variant; verify pressure rating before substitution
- MKS Instruments 1179A / 1479A – Industry-standard alternative; requires signal adapter for some controllers
- Horiba SEC-Z512MGX – Compatible range; confirm full-scale flow and gas calibration
- Alicat MC Series – Modern digital alternative with RS-232/RS-485; suitable for retrofit projects
- Fujikin FCST-series – Used in AMAT and Lam Research tool replacements
⚠ Always verify gas type, full-scale flow range, pressure rating, and connector pinout before substitution. Contact Konmask for cross-reference support.
Why Choose the Original Model
- OEM-matched calibration: Factory-calibrated for CF4 — no recalibration required on drop-in replacement
- Proven reliability: Brooks 5964-EP is a field-proven MFC widely deployed in CVD, etch, and ALD processes
- Halogen-resistant wetted path: EP (Enhanced Performance) designation indicates upgraded materials for aggressive gases like CF4, NF3, and Cl2
- Long service life: Designed for continuous duty in cleanroom environments
- OEM spare parts availability: Valve seats, seals, and PCBs available for depot-level repair
Typical Applications
- Semiconductor CVD (Chemical Vapor Deposition) — CF4 chamber clean
- Plasma etch tools (RIE, ICP) — fluorine-based etch chemistry
- ALD (Atomic Layer Deposition) precursor delivery
- Flat panel display (FPD) manufacturing
- Solar cell thin-film deposition
- Industrial gas blending and calibration systems
System Compatibility
- OEM Tools: Applied Materials (AMAT), Lam Research, Tokyo Electron (TEL), Novellus, ASM International
- MFC Controllers: Brooks 0254, MKS 247D/647C, Horiba UR-7300, Unit Instruments UFC-7300B
- Communication: Analog 0–5 V / 4–20 mA; optional DeviceNet or RS-485 (model-dependent)
- Gas Panel Integration: Compatible with standard VCR/VCO face-seal fittings (1/4″ and 1/8″)
Selection Guide
Use the table below to select the correct Brooks 5964-EP configuration for your application:
- Step 1 – Gas type: Confirm CF4 service; for NF3 or Cl2, request EP+ or specialty wetted variant
- Step 2 – Full-scale flow range: Match to your process recipe (e.g., 10 sccm, 50 sccm, 200 sccm, 1 slm)
- Step 3 – Pressure rating: Verify inlet/outlet pressure against your gas panel spec
- Step 4 – Signal interface: Confirm 0–5 VDC or 4–20 mA with your MFC controller
- Step 5 – Fitting type: VCR, VCO, or compression — specify at order
- Step 6 – Valve type: Normally Closed (NC) standard; Normally Open (NO) available on request

Replacement & Compatibility FAQ
Q: Can the Brooks 5964-EP replace a Brooks 5850E directly?
A: In most cases yes — the 5964 series is the successor to the 5850 series with the same D-Sub 15-pin interface. Verify full-scale flow range and gas calibration match.
Q: Is the 5964-EP suitable for NF3 or WF6?
A: The EP designation covers CF4 and similar fluorinated gases. For NF3 or WF6, request the EP+ or specialty corrosion-resistant variant and confirm with Konmask.
Q: What is the difference between P/N 0040-39138 and 2305144-B?
A: These are cross-reference part numbers used by different OEM tool manufacturers for the same Brooks 5964-EP unit. Both refer to the same device.
Q: Can I use an MKS 1179A as a drop-in replacement?
A: The MKS 1179A is functionally equivalent but uses a different connector pinout. A wiring adapter or harness modification is typically required.
Q: Do you offer calibration services?
A: Yes. Konmask partners with certified MFC calibration labs. Contact us for recalibration, repair, or exchange programs.
