MCP3424T-E/ST Equivalent & Substitute Parts

Part Overview

The MCP3424T-E/ST is an 18-bit Sigma-Delta analog-to-digital converter manufactured by Microchip Technology, designed for multi-channel data acquisition applications. This device features 4 differential inputs, integrated programmable gain amplifier (PGA), and I2C digital interface, operating across a wide supply voltage range of 2.7V to 5.5V. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications requiring high-resolution analog signal conversion.

Identifying equivalent and substitute parts is necessary when the primary packaging format (Cut Tape with Digi-Reel) is unavailable, when alternative inventory sources are required, or when design flexibility permits alternative packaging configurations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP3424T-E/ST is determined by strict equivalence across all electrical and mechanical parameters. The substitute part MCP3424-E/ST qualifies as a direct equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical 18-bit resolution and 4 differential input configuration
• Matching 3.75 samples-per-second sampling rate
• Identical Sigma-Delta architecture with integrated MUX-PGA-ADC configuration
• Matching I2C digital interface protocol
• Identical internal reference type
• Matching supply voltage range (2.7V ~ 5.5V for both analog and digital supplies)
• Identical operating temperature range (-40°C ~ 125°C)

Mechanical Parameter Equivalence:

• Identical 14-TSSOP package footprint (0.173", 4.40mm Width)
• Identical surface mount mounting type
• Same base product number (MCP3424)

Compliance & Status Equivalence:

• Both parts maintain Active product status
• Both parts are ROHS3 compliant
• Both parts have MSL rating of 1 (Unlimited)
• Both parts are REACH Unaffected
• Identical ECCN and HTSUS classifications

The only difference between the main part and substitute is the packaging format: MCP3424T-E/ST is supplied in Cut Tape with Digi-Reel, while MCP3424-E/ST is supplied in Tube packaging. This packaging difference does not affect electrical performance, pin configuration, or functional capability.

Parameter Comparison

Engineering Selection Recommendations

The MCP3424-E/ST qualifies as a direct electrical and mechanical equivalent to the MCP3424T-E/ST. Both parts are manufactured by Microchip Technology and maintain identical Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Selection between these parts should be based on packaging and supply chain requirements:

MCP3424T-E/ST (Cut Tape with Digi-Reel): Suitable for high-volume automated assembly operations where tape-and-reel packaging provides optimal handling efficiency and component feeding through pick-and-place equipment.

MCP3424-E/ST (Tube): Suitable for lower-volume production runs, manual assembly operations, or applications where tube packaging provides preferred storage and handling characteristics.

Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory and trade compliance status.

Frequently Asked Questions (FAQ)

Q: Are MCP3424T-E/ST and MCP3424-E/ST electrically identical?

A: Yes. Both parts are electrically identical with matching 18-bit resolution, 4 differential inputs, 3.75 samples-per-second sampling rate, Sigma-Delta architecture, I2C interface, and identical supply voltage and operating temperature ranges. The only difference is packaging format.

Q: Can I substitute MCP3424-E/ST for MCP3424T-E/ST in my PCB design?

A: Yes. Both parts use the identical 14-TSSOP package footprint with 0.173" width and 4.40mm dimensions. Pin configuration and spacing are identical, allowing direct substitution on the same PCB layout without design modifications.

Q: What is the difference between Cut Tape/Digi-Reel and Tube packaging?

A: Cut Tape with Digi-Reel packaging supplies components on continuous tape wound on a reel, optimized for automated pick-and-place assembly. Tube packaging supplies components in a plastic tube, typically used for manual assembly or lower-volume applications. Both formats contain the same component with identical electrical specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both MCP3424T-E/ST and MCP3424-E/ST are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: Which part should I select for high-volume manufacturing?

A: MCP3424T-E/ST in Cut Tape with Digi-Reel format is optimized for high-volume automated assembly operations. MCP3424-E/ST in Tube format is suitable for lower-volume or manual assembly scenarios.

Q: Do both parts have the same selectable address feature?

A: Yes. Both parts include PGA (Programmable Gain Amplifier) and Selectable Address features, enabling flexible I2C addressing in multi-device configurations.
