AR1010T-I/SO Equivalent & Substitute Parts

Part Overview

The AR1010T-I/SO is a touchscreen controller 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 currently in active production status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when packaging or distribution channel requirements differ while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AR1010T-I/SO is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is the packaging format: the AR1010T-I/SO is supplied in Tape & Reel (TR) format, while the AR1010-I/SO is supplied in Tube format. Both parts share identical specifications for touchscreen controller functionality, resolution, interface protocol, voltage supply range, current consumption, operating temperature range, package case dimensions, and compliance certifications.

Key parameters governing substitution:

• Base product number (AR1010)
• Touchscreen configuration (4, 5, or 8 Wire Resistive)
• Resolution (10 bits)
• Interface type (UART)
• Supply voltage (2.5V ~ 5V)
• Supply current (17 mA)
• Operating temperature range (-40°C ~ 85°C)
• Package case (20-SOIC, 0.295", 7.50mm Width)
• Mounting type (Surface Mount)
• Compliance status (ROHS3, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

Both AR1010T-I/SO and AR1010-I/SO are active production parts from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional capability.

The AR1010T-I/SO in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding into pick-and-place equipment is standard practice. The AR1010-I/SO in Tube packaging is appropriate for lower-volume applications, manual assembly processes, or situations where individual component handling is preferred.

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and consumer applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for either part.

Frequently Asked Questions (FAQ)

Q: Can AR1010-I/SO (Tube) be used as a direct replacement for AR1010T-I/SO (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Substitution is valid provided your assembly process can accommodate Tube packaging instead of Tape & Reel format.

Q: Are there any functional differences between the two part numbers?

A: No. Both parts share identical specifications for touchscreen controller functionality, 10-bit resolution, UART interface, supply voltage range (2.5V ~ 5V), current consumption (17 mA), operating temperature range (-40°C ~ 85°C), and 20-SOIC package dimensions.

Q: What determines whether these parts are interchangeable?

A: Interchangeability is determined by matching electrical parameters (voltage, current, interface protocol, resolution), mechanical parameters (package type, dimensions, mounting method), and compliance certifications (RoHS3, REACH status). All these parameters are identical between AR1010T-I/SO and AR1010-I/SO.

Q: Does packaging format affect PCB assembly compatibility?

A: Packaging format affects supply chain logistics and assembly equipment compatibility, not PCB-level functionality. Tape & Reel format integrates with automated pick-and-place systems, while Tube format requires manual or semi-automated handling. The actual component mounted on the PCB is identical.

Q: Are both parts currently available?

A: Both parts maintain active production status. AR1010T-I/SO has 3200 pcs in stock; AR1010-I/SO has 2160 pcs in stock.
