TSC2003IPWG4 Equivalent & Substitute Parts

Part Overview

The TSC2003IPWG4 is a touchscreen controller IC designed for 4-wire resistive touch panels with 12-bit resolution and I2C interface communication. Manufactured by Texas Instruments, this component operates across a 2.5V to 5.25V supply range and is housed in a 16-TSSOP surface mount package. The TSC2003IPWG4 is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and production continuity. The TSC2003IPW serves as the active equivalent for this application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSC2003IPWG4 is determined by strict equivalence across the following critical parameters:

• Touchscreen Interface: 4-wire resistive topology
• Resolution: 12-bit analog-to-digital conversion
• Communication Protocol: I2C serial interface
• Voltage Reference Architecture: Internal reference
• Supply Voltage Compatibility: 2.5V to 5.25V operating range
• Package Footprint: 16-TSSOP with identical pin configuration
• Temperature Rating: -40°C to 85°C operational envelope

The TSC2003IPW maintains identical electrical specifications and mechanical compatibility with the TSC2003IPWG4, differing only in packaging format (tube versus alternative packaging) and product status (active versus discontinued).

Parameter Comparison

Engineering Selection Recommendations

The TSC2003IPW is the direct equivalent for TSC2003IPWG4 applications. Both components share identical electrical characteristics, pin configuration, and mechanical footprint. The TSC2003IPW is currently in active production status, whereas the TSC2003IPWG4 is discontinued. For new designs or production continuity, the TSC2003IPW is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and consumer applications. The packaging difference (tube format for TSC2003IPW) does not affect functional performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can TSC2003IPW directly replace TSC2003IPWG4 on existing PCBs?

A: Yes. Both parts use identical 16-TSSOP package geometry with matching pin assignments. No PCB layout modifications are required.

Q: Are there electrical performance differences between these parts?

A: No. Both components provide 12-bit resolution, I2C interface, internal voltage reference, and identical supply voltage range (2.5V to 5.25V). Operating temperature ratings are equivalent at -40°C to 85°C.

Q: What is the significance of the packaging difference?

A: TSC2003IPWG4 uses standard packaging while TSC2003IPW is supplied in tube format. This affects handling and storage procedures but does not impact electrical function or PCB performance.

Q: Why is TSC2003IPWG4 discontinued?

A: Product discontinuation at distributor level typically reflects inventory consolidation or manufacturer product line optimization. The TSC2003IPW remains the active equivalent for this touchscreen controller application.

Q: Are both parts RoHS compliant?

A: Yes. Both TSC2003IPWG4 and TSC2003IPW are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial applications.

Q: What touchscreen panel types are compatible with these controllers?

A: Both parts are designed for 4-wire resistive touchscreen interfaces. They are not compatible with capacitive or other touchscreen technologies.
