MIC2155YML-TR Equivalent & Substitute Parts Reference

Part Overview

The MIC2155YML-TR, manufactured by Microchip Technology, is a power management IC (PMIC) designed as a buck regulator step-down DC-DC controller. It features a positive output configuration, transistor driver outputs, dual output phases, synchronous rectification, and a variety of control features. This product is currently classified as Active. Identification and validation of substitute parts is necessary for ensuring supply chain continuity, maintaining inventory consistency, and supporting multi-source BOM management within the power management (PMIC) category. All substitute decisions must be guided by equivalence in electrical, mechanical, and environmental compliance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for MIC2155YML-TR is based solely on equivalence in the following explicit parameters: manufacturer, category (power management PMIC), electrical function (buck step-down controller), output configuration and topology, key electrical characteristics (number of outputs, voltage supply range, switching frequency, duty cycle, number of phases), physical features (mounting type, package/case, supplier device package), control features, operating temperature, compliance certifications (RoHS, MSL, REACH), and part status. No parameter outside those explicitly provided is used for determining substitute eligibility.

The substitute listed matches all required parameters for electrical, mechanical, and compliance equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MIC2155YML-TR is classified as Active and complies with ROHS3, MSL 3, and REACH standards. Selection of this part ensures full alignment with regulatory requirements and supply chain compatibility for regulated environments. No differences exist between the main and substitute parts in available data regarding compliance or certification, supporting direct interchangeability for engineering and procurement purposes.
