MCP73223T-C2SI/MF Equivalent & Substitute Parts

Part Overview

The MCP73223T-C2SI/MF is an active Lithium Iron Phosphate battery charger IC manufactured by Microchip Technology. This Power Management (PMIC) component operates in the 10-VFDFN Exposed Pad package and is designed for single to dual-cell battery charging applications. The device is ROHS3 compliant and currently in active production status. Alternative part numbers exist within the same product family to accommodate different packaging and moisture sensitivity requirements in supply chain scenarios.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP73223T-C2SI/MF is determined by strict equivalence across the following critical parameters:

Battery Chemistry: Lithium Iron Phosphate
Number of Cells: 1 ~ 2
Charge Current - Max: 1.1A
Battery Pack Voltage: 7.2V
Voltage - Supply (Max): 16V
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 10-VFDFN Exposed Pad
Mounting Type: Surface Mount
Current - Charging: Constant - Programmable
Programmable Features: Current, Timer
Fault Protection: Over Temperature, Over Voltage, Reverse Current

All substitute parts must maintain identical electrical specifications and physical package dimensions. Variations in packaging format (Cut Tape & Digi-Reel versus Tube) and moisture sensitivity level (MSL) do not affect functional equivalence but reflect different supply chain and storage conditions.

Engineering Selection Recommendations

Both MCP73223T-C2SI/MF and MCP73223-C2SI/MF are active products from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts is determined by supply chain and storage requirements rather than functional performance.

MCP73223T-C2SI/MF in Cut Tape & Digi-Reel packaging with MSL 1 rating is suitable for applications with extended storage periods or environments with high humidity exposure prior to assembly.

MCP73223-C2SI/MF in Tube packaging with MSL 3 rating is suitable for applications with controlled storage conditions and shorter lead times between receipt and assembly.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can MCP73223-C2SI/MF replace MCP73223T-C2SI/MF in production?

A: Yes. Both parts are electrically and mechanically identical. The difference lies in packaging format and moisture sensitivity rating. Selection depends on your supply chain and storage environment.

Q: What does the MSL rating difference mean?

A: MSL 1 (Unlimited) indicates the component can be stored indefinitely in standard conditions. MSL 3 (168 Hours) indicates the component must be assembled within 168 hours of opening the moisture barrier bag after exposure to ambient humidity. Choose based on your assembly timeline and storage capabilities.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 10-VFDFN Exposed Pad package with identical physical dimensions and pin configurations. PCB layout and footprints are interchangeable.

Q: Do both parts support the same charging specifications?

A: Yes. Both parts support 1.1A maximum charge current, 7.2V battery pack voltage, 16V maximum supply voltage, and identical programmable current and timer features with the same fault protection mechanisms.

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

A: Cut Tape & Digi-Reel packaging is supplied on continuous tape suitable for automated pick-and-place equipment. Tube packaging is supplied in bulk containers. Both formats contain the same component; packaging choice depends on assembly equipment and volume requirements.
