PCAP01A DICE Equivalent & Substitute Parts

Part Overview

The PCAP01A DICE is a Capacitance-to-Digital Converter from ScioSense's PICOCAP® series, designed for 17-bit resolution capacitive sensing applications with 500k sampling rate. This die-form component operates across -40°C to 125°C and supports both I2C and SPI interfaces with a single supply voltage range of 2.1V to 3.6V. The product is currently obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the PCAP01A DICE is determined by the following critical parameters that must remain consistent:

• Manufacturer: ScioSense (same product family)
• Series: PICOCAP® (same technology platform)
• Type: Capacitance-to-Digital Converter (same functional class)
• Number of Channels: 8 (same channel count)
• Resolution: 17 bits (same resolution specification)
• Data Interface: I2C, SPI (same communication protocols)
• Voltage Supply: 2.1V ~ 3.6V (same supply range)
• Operating Temperature: -40°C ~ 125°C (same temperature range)
• RoHS and REACH Compliance: Maintained across all substitutes

The substitute parts PCAP01AD and PCAP01AD 1K maintain all critical electrical parameters while transitioning from die form to packaged 32-QFN form factor, enabling integration into standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The PCAP01A DICE is obsolete and no longer in active production. Both PCAP01AD and PCAP01AD 1K are active products from ScioSense and maintain full electrical and functional compatibility with the original die specification.

Selection between PCAP01AD and PCAP01AD 1K should be based on packaging and inventory requirements. Both parts are RoHS Compliant and REACH Unaffected, meeting current regulatory standards. The transition from die form to 32-QFN packaged form factor enables standard surface mount assembly processes while preserving all core capacitive sensing functionality.

Frequently Asked Questions (FAQ)

Q: Can PCAP01AD or PCAP01AD 1K directly replace PCAP01A DICE in existing designs?

A: Yes. Both substitute parts maintain identical electrical specifications including 17-bit resolution, 8-channel configuration, I2C/SPI interfaces, and 2.1V to 3.6V supply voltage. The primary difference is packaging: PCAP01A DICE is supplied as a bare die, while PCAP01AD and PCAP01AD 1K are packaged in 32-QFN form factor suitable for standard PCB assembly.

Q: What is the difference between PCAP01AD and PCAP01AD 1K?

A: Both parts are electrically identical with the same 17-bit resolution, 8-channel configuration, and operating parameters. The designation "1K" in PCAP01AD 1K indicates packaging quantity or tape reel configuration. Electrical functionality and performance are equivalent.

Q: Are there sampling rate differences between the main part and substitutes?

A: The PCAP01A DICE specifies 500k sampling rate per second. The PCAP01AD and PCAP01AD 1K do not list a specific sampling rate parameter in their specifications, but maintain all other electrical and functional characteristics of the original part.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both PCAP01AD and PCAP01AD 1K are RoHS Compliant and REACH Unaffected, matching the compliance status of the obsolete PCAP01A DICE.

Q: What are the moisture sensitivity considerations for these parts?

A: PCAP01A DICE has MSL 1 (Unlimited). PCAP01AD and PCAP01AD 1K have MSL 3 (168 Hours), indicating standard moisture sensitivity handling requirements for packaged components.
