AR1010T-I/ML Equivalent & Substitute Parts

Part Overview

The AR1010T-I/ML is a touchscreen controller IC manufactured by Microchip Technology, designed for resistive touchscreen applications supporting 4, 5, or 8-wire configurations. This 10-bit resolution device communicates via UART interface and operates across a 2.5V to 5V supply range. The part is actively produced and widely used in human-machine interface applications requiring reliable touch input processing.

Substitute parts are identified when design requirements permit component interchange without compromising electrical performance, mechanical compatibility, or regulatory compliance. The AR1010T-I/ML and its direct substitute share identical functional specifications while differing in packaging format and moisture sensitivity characteristics.

Substitute Part Grouping Explanation

The AR1010T-I/ML and AR1010-I/ML are direct substitutes within the AR1010 base product family. Substitution eligibility is determined by the following critical parameters:

• Touchscreen Interface Compatibility: Both parts support identical 4, 5, or 8-wire resistive touchscreen configurations
• Resolution and Signal Processing: Both deliver 10-bit resolution via UART communication protocol
• Electrical Specifications: Identical supply voltage range (2.5V ~ 5V), supply current (17 mA), and operating temperature range (-40°C ~ 85°C)
• Package and Pinout: Both use 20-VFQFN Exposed Pad package with identical mechanical footprint and pin configuration
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

The primary differences between these parts are packaging format (Tube vs. standard) and moisture sensitivity level (MSL 3 vs. MSL 1), which do not affect functional interchangeability in circuit design.

Parameter Comparison

Engineering Selection Recommendations

Both AR1010T-I/ML and AR1010-I/ML are active production parts from Microchip Technology with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on supply chain availability and storage conditions:

• AR1010T-I/ML is suitable for applications with standard moisture control during storage and assembly
• AR1010-I/ML offers extended moisture tolerance (MSL 1) and is preferred for environments with extended lead times or variable humidity conditions

Both parts are functionally equivalent for circuit design purposes and require no design modifications when substituting one for the other.

Frequently Asked Questions (FAQ)

Q: Can AR1010-I/ML be used as a direct replacement for AR1010T-I/ML in production?

A: Yes. Both parts are functionally identical in electrical performance, interface protocol, and package footprint. No circuit modifications are required.

Q: What is the significance of the different MSL ratings?

A: MSL 3 (168 Hours) indicates the part can be exposed to moisture for up to 168 hours before soldering. MSL 1 (Unlimited) means the part has no time restriction for moisture exposure. This affects storage and handling procedures but not electrical function.

Q: Are the pinouts identical between these two parts?

A: Yes. Both parts use the 20-VFQFN Exposed Pad package with identical pin configuration and mechanical footprint.

Q: Does the packaging format (Tube vs. standard) affect performance?

A: No. Packaging format is a supply and handling consideration only. Electrical and functional performance is identical.

Q: What touchscreen configurations are supported?

A: Both parts support 4-wire, 5-wire, and 8-wire resistive touchscreen topologies through the same UART interface.

Q: Are both parts suitable for the full -40°C to 85°C temperature range?

A: Yes. Both parts are rated for identical operating temperature ranges and maintain specified performance across this range.
