TSC2004IRTJTG4 Equivalent & Substitute Parts

Part Overview

The TSC2004IRTJTG4 is a touchscreen controller IC designed for 4-wire resistive touch panels with 12-bit resolution. It communicates via I2C and Serial interfaces and operates across a supply voltage range of 1.2V to 3.6V. The part is packaged in a 20-QFN (4x4) form factor with an exposed pad and is mounted as a surface mount component.

The TSC2004IRTJTG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSC2004IRTJTG4 is determined by the following critical parameters:

• Touchscreen controller type and resolution (4-wire resistive, 12-bit)
• Communication interface compatibility (I2C and Serial)
• Electrical specifications (supply voltage 1.2V ~ 3.6V, supply current 797 µA)
• Package form factor (20-QFN with exposed pad)
• Operating temperature range (-40°C ~ 85°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

The TSC2004IRTJT qualifies as a direct substitute based on identical electrical characteristics, interface specifications, and package requirements. The primary difference is packaging format: the substitute uses Cut Tape (CT) & Digi-Reel® packaging instead of Tape & Reel (TR).

Parameter Comparison

Engineering Selection Recommendations

The TSC2004IRTJT is the direct substitute for the discontinued TSC2004IRTJTG4. Both parts share identical electrical specifications, interface protocols, and package geometry. The substitute maintains active product status and full compliance with ROHS3 and REACH requirements.

The only distinction between the main part and substitute is the packaging format. The TSC2004IRTJT is supplied in Cut Tape (CT) & Digi-Reel® format, whereas the original part uses Tape & Reel (TR) packaging. This difference affects handling and assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are the TSC2004IRTJTG4 and TSC2004IRTJT electrically identical?

A: Yes. Both parts have identical electrical specifications, including supply voltage range (1.2V ~ 3.6V), supply current (797 µA), resolution (12 bits), interface protocols (I2C and Serial), and operating temperature range (-40°C ~ 85°C).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, typically for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on tape that has been cut into smaller quantities, suitable for lower-volume or mixed-component orders. Both formats contain the same component in the same package.

Q: Can the TSC2004IRTJT be used as a direct replacement in existing designs?

A: Yes. The TSC2004IRTJT is a direct functional and mechanical substitute. The 20-QFN package geometry, pin configuration, and electrical characteristics are identical. Assembly and soldering processes remain unchanged.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level (MSL) 2 (1 Year) ratings.

Q: Why is the original part discontinued?

A: The TSC2004IRTJTG4 is discontinued at DiGi Electronics. The TSC2004IRTJT remains in active production and is the recommended substitute for continued component availability.
