MCP4901T-E/SN Equivalent & Substitute Parts

Part Overview

The MCP4901T-E/SN is an 8-bit Digital to Analog Converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring voltage output conversion. This single-channel DAC operates across a wide supply voltage range (2.7V to 5.5V for both analog and digital supplies) and communicates via SPI interface with an external voltage reference. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical specifications, package compatibility, and compliance certifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP4901T-E/SN is determined by strict alignment of the following critical parameters:

• Resolution and Channel Configuration: 8-bit resolution with single D/A converter
• Output Characteristics: Voltage output with buffered configuration
• Communication Protocol: SPI data interface
• Supply Voltage Compatibility: Dual supply range of 2.7V to 5.5V for both analog and digital domains
• Electrical Performance: Settling time of 4.5µs (Typ) and INL/DNL specifications of ±0.25 and ±0.2 LSB
• Package Specification: 8-SOIC surface mount package with 0.154" width (3.90mm)
• Compliance Requirements: RoHS3 compliance and REACH unaffected status

The MCP4901-E/SN qualifies as a direct substitute based on identical alignment across all specified electrical parameters, package dimensions, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MCP4901-E/SN serves as a direct functional equivalent to the MCP4901T-E/SN. Both components maintain Active product status from Microchip Technology and carry identical RoHS3 compliance and REACH unaffected certifications. The primary distinction between these parts is packaging format: the MCP4901T-E/SN is supplied in standard packaging, while the MCP4901-E/SN is supplied in Tube packaging. This packaging difference does not affect electrical performance, thermal characteristics, or regulatory compliance. Selection between these parts should be based on procurement requirements and packaging preferences for assembly operations.
