QT60168-AS Equivalent & Substitute Parts

Part Overview

The QT60168-AS is a capacitive touch sensor IC from Microchip Technology designed for 16-channel QMatrix touch button applications in a 32-TQFP surface mount package. This component interfaces via SPI and supports 9-bit resolution with supply voltage range of 3V to 5.25V. The QT60168-AS is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

The QT60168-ASG qualifies as a direct substitute for the QT60168-AS based on the following matching parameters:

• Identical number of inputs (16 channels)
• Identical SPI interface protocol
• Identical resolution (9-bit)
• Identical supply voltage range (3V ~ 5.25V)
• Identical maximum supply current (25mA)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical package type and dimensions (32-TQFP, 7x7mm)
• Identical mounting type (Surface Mount)
• Identical MSL rating (3, 168 Hours)

The primary distinction is product status: QT60168-AS is obsolete while QT60168-ASG is active, with improved RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The QT60168-ASG is the direct functional equivalent of the QT60168-AS. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility. The QT60168-ASG is the preferred selection for new designs and production applications due to its active product status and ROHS3 compliance. For legacy systems currently using QT60168-AS, migration to QT60168-ASG presents no technical barriers and provides improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can QT60168-ASG replace QT60168-AS in existing designs? A: Yes. The QT60168-ASG is functionally and electrically identical to the QT60168-AS across all specified parameters. No design modifications are required.

Q: Are there any pin configuration differences between these parts? A: No. Both parts use the 32-TQFP package with identical pinout and signal assignments.

Q: What is the difference in packaging between these parts? A: QT60168-AS is supplied in tube packaging, while QT60168-ASG is supplied in tray packaging. This affects handling and storage but does not impact component functionality.

Q: Why is QT60168-AS marked as obsolete? A: QT60168-AS has been superseded by QT60168-ASG, which offers improved RoHS compliance and active manufacturer support.

Q: Are the supply voltage and current specifications identical? A: Yes. Both parts operate at 3V to 5.25V supply voltage with a maximum supply current of 25mA.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. The identical 32-TQFP package dimensions and pinout allow direct substitution without PCB modifications.
