100% Compatible Replacement for the Discontinued DMC AST-070A080A Touchscreen
Protecting Existing Designs and Series Production from Component Discontinuation
Component discontinuation is one of the most disruptive events in the lifecycle of an industrial product. When a proven, widely deployed component reaches end of life, manufacturers face a difficult choice: either source a compatible replacement quickly, or commit to a costly and time-consuming redesign of the existing system.
DMC has discontinued its established 7-inch resistive touchscreen, the AST-070A080A - a component used across a range of industrial applications and active series production lines. To protect customers from the consequences of this discontinuation, FORTEC worked directly with DMC to develop a purpose-built successor.
A Drop-In Successor - No Redesign Required
The result of this collaboration is the TP-4845S1F0, a 7-inch resistive touchscreen developed specifically to replace the AST-070A080A without requiring any modifications to the existing system design.
Compatibility is complete across all relevant dimensions:
- Identical mechanical dimensions and mounting configuration
- Identical pin assignment for direct electrical compatibility
- Proven 4-wire resistive touch technology, consistent with the original
- Same operational characteristics for gloved-hand use in industrial environments
Customers currently using the AST-070A080A in production systems or active development projects can transition to the TP-4845S1F0 without hardware modifications, software changes, or requalification of the mechanical integration.
Built for Industrial Environments
The 4-wire resistive touch technology used in the TP-4845S1F0 is particularly well suited to industrial operating conditions. Unlike capacitive touch, resistive technology responds reliably to input through protective gloves, and is not affected by water, dust, or other surface contaminants. This makes it the preferred choice for machine operator panels, industrial HMI systems, and any application where dependable input under demanding conditions is a requirement.
Exclusive Long-Term Availability Through FORTEC Switzerland
The TP-4845S1F0 is available exclusively through FORTEC, ensuring a controlled and reliable supply channel for customers who depend on this component for ongoing production. Long-term availability is secured, providing the planning certainty that industrial series production programmes require.
