Compatible Replacement & Equivalent Models
When the original QTERM-G72/3945R is unavailable or discontinued, the following replacement strategies are recommended:
- Direct OEM Replacement: QSI QTERM-G72/3945R (original part) — preferred for warranty-critical systems
- Series-Compatible Glass: Other QTERM-G72 series touch glass variants with matching dimensions and connector pinout
- Third-Party Equivalent: Aftermarket resistive touch panels with identical active area dimensions (verify connector type before ordering)
- Upgrade Path: Consider QTERM-G75 or QTERM-G76 series if full terminal replacement is acceptable — offers improved resolution and modern connectivity
Note: Always verify part dimensions, connector type, and firmware compatibility before substituting touch glass components.
Why Choose the Original Model
- Guaranteed fit and form factor for QTERM-G72 enclosures
- Certified compatibility with QSI firmware and calibration routines
- Maintains original IP rating and environmental sealing
- Supports OEM warranty and service agreements
- Eliminates integration risk in safety-critical or regulated environments
Typical Applications
- PLC-based machine control panels requiring HMI glass replacement
- Food & beverage processing lines with washdown-rated terminals
- Oil & gas field operator interface terminals
- Water treatment and utilities SCADA operator stations
- Automotive assembly line HMI maintenance and repair
- Packaging machinery and conveyor control systems
System Compatibility
The QTERM-G72/3945R touch glass is designed for use within the QSI QTERM-G72 terminal platform. Confirmed compatible systems include:
- QSI QTERM-G72 series operator terminals (all sub-variants)
- Systems integrated with Allen-Bradley, Siemens, Mitsubishi, and Omron PLCs via QTERM serial/Ethernet interfaces
- Panels running QSI KeyPAC or compatible HMI runtime software
Selection Guide
Use the following checklist when selecting a replacement touch screen panel glass:
- ✅ Confirm terminal model: QTERM-G72 (not G55, G75, or G76)
- ✅ Verify active area dimensions match existing glass
- ✅ Check connector type: FPC ribbon vs. discrete wire harness
- ✅ Confirm touch technology: resistive (not capacitive) for gloved-hand environments
- ✅ Review environmental rating requirements (IP65 / NEMA 4X)
- ✅ Validate firmware version compatibility with QSI support if using aftermarket glass

Replacement & Compatibility FAQ
Q: Can I use a capacitive touch glass instead of the original resistive panel?
A: Not recommended. Resistive touch is required for gloved-hand operation common in industrial environments. Capacitive glass will not function correctly without firmware modification.
Q: Is the QTERM-G72/3945R still in production?
A: QSI has transitioned newer product lines; availability may be limited to OEM surplus and refurbished stock. Contact us to confirm current inventory.
Q: What is the difference between QTERM-G72/3945R and other QTERM-G72 glass variants?
A: The suffix (3945R) denotes the specific display size and connector configuration. Always match the full part number when ordering replacement glass.
Q: Do you provide installation support?
A: We provide technical documentation and remote guidance. On-site installation services are available through our partner network — contact us for details.
