MCP73213T-A6W/MF Equivalent & Substitute Parts

Part Overview

The MCP73213T-A6W/MF is an active lithium ion/polymer battery charger IC manufactured by Microchip Technology, classified as a Power Management PMIC. This single-cell to dual-cell charger operates with a maximum supply voltage of 13V and delivers programmable constant charging current up to 1.1A, with integrated over-voltage fault protection. The device is housed in a 10-VFDFN exposed pad package (3x3mm) and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or packaging format requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

All substitute parts for the MCP73213T-A6W/MF maintain identical electrical specifications and mechanical compatibility. Substitution is determined by the following critical parameters:

Battery Chemistry: Lithium Ion/Polymer
Number of Cells: 2
Charge Current - Max: 1.1A
Battery Pack Voltage: 8.4V
Voltage - Supply (Max): 13V
Fault Protection: Over Voltage
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 10-VFDFN Exposed Pad
Mounting Type: Surface Mount

The five substitute part numbers differ only in packaging format (Tape & Reel vs. Cut Tape vs. Digi-Reel®), which does not affect electrical performance or mechanical fit. All parts share the same base product number MCP73213 and are manufactured by Microchip Technology with active product status.

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the MCP73213T-A6W/MF. Selection should be based on:

Packaging Format Requirements: Choose based on assembly process requirements. Tape & Reel (TR) packaging is suitable for high-volume automated pick-and-place operations. Cut Tape (CT) and Digi-Reel® formats accommodate lower-volume or mixed-component assembly workflows.

Inventory Availability: MCP73213T-A61I/MF offers the highest inventory level (9400 pcs), providing supply security for immediate procurement needs. Alternative options maintain adequate stock levels ranging from 1586 to 3702 pcs.

Compliance Status: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with current manufacturing and environmental standards.

Product Status: All parts carry active product status from Microchip Technology, confirming ongoing manufacturer support and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can MCP73213T-A61I/MF be used as a direct replacement for MCP73213T-A6W/MF?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications, operating temperature range, and package type. The difference is packaging format only (Cut Tape & Digi-Reel® vs. Tape & Reel). Electrical performance and PCB footprint are identical.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated assembly. Cut Tape (CT) provides the same components on shorter tape segments, suitable for lower-volume production or manual assembly. Both formats use identical component specifications and 10-VFDFN package geometry.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, meeting current environmental and hazardous substance restrictions.

Q: Can I mix packaging formats in a single production run?

A: Yes. All substitute parts share identical electrical characteristics, operating parameters, and physical package dimensions. Packaging format differences do not affect circuit performance or PCB assembly compatibility.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All substitute parts carry this rating, eliminating moisture sensitivity concerns during storage and handling.

Q: Are there any differences in fault protection between substitute parts?

A: No. All substitute parts provide identical over-voltage fault protection specifications and operating temperature range (-40°C ~ 85°C).
