MCP73113T-16SI/MF Equivalent & Substitute Parts

Part Overview

The MCP73113T-16SI/MF is a single-cell lithium ion/polymer battery charger IC manufactured by Microchip Technology. This active product operates as a constant-current/constant-voltage charger with integrated over-voltage fault protection, designed for portable and embedded power management applications. The part is supplied in Tape & Reel packaging with 751 units currently in stock. Alternative part sourcing becomes necessary due to packaging availability, inventory constraints, or supply chain requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP73113T-16SI/MF is determined by strict equivalence across the following critical parameters:

• Identical base product number (MCP73113)
• Matching battery chemistry (Lithium Ion/Polymer)
• Single-cell configuration
• Constant-current/constant-voltage charging capability
• Maximum charge current of 1.1A
• Battery pack voltage of 4.1V
• Maximum supply voltage of 6.5V
• Over-voltage fault protection
• Operating temperature range of -40°C to 85°C
• 10-VFDFN Exposed Pad package with surface mount capability
• ROHS3 compliance and MSL 1 rating

The primary distinction between the main part and substitute relates to packaging format (Tape & Reel versus Tube), which does not affect electrical performance or mechanical compatibility on the PCB.

Parameter Comparison

Engineering Selection Recommendations

Both MCP73113T-16SI/MF and MCP73113-16SI/MF are active products from Microchip Technology with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

• Packaging availability and supply chain requirements
• Inventory levels (MCP73113-16SI/MF currently has 3440 units available versus 751 units for the main part)
• Assembly process compatibility with Tube versus Tape & Reel formats
• Cost considerations associated with packaging format

Both parts maintain full ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring equivalent reliability and environmental compliance for production applications.

Frequently Asked Questions (FAQ)

Q: Can MCP73113-16SI/MF be used as a direct replacement for MCP73113T-16SI/MF?

A: Yes. Both parts share identical electrical specifications, charge current ratings, voltage parameters, fault protection, operating temperature range, and package footprint. The only difference is the packaging format (Tube versus Tape & Reel), which does not affect PCB-level compatibility or performance.

Q: What is the significance of the packaging format difference?

A: The "T" designation in MCP73113T-16SI/MF indicates Tape & Reel packaging, while MCP73113-16SI/MF uses Tube packaging. Both formats contain the same component in the same 10-VFDFN package. The choice between formats depends on assembly equipment capabilities and volume requirements rather than technical performance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, MSL 1 rating, and EAR99 ECCN classification. They are functionally and environmentally equivalent.

Q: What parameters must remain constant for substitution eligibility?

A: The following parameters must match exactly: base product number (MCP73113), battery chemistry (Lithium Ion/Polymer), single-cell configuration, 1.1A maximum charge current, 4.1V battery pack voltage, 6.5V maximum supply voltage, over-voltage protection, -40°C to 85°C operating temperature, and 10-VFDFN Exposed Pad package with surface mount mounting.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, provided the assembly process supports both Tape & Reel and Tube packaging formats. The electrical and mechanical specifications are identical, making them suitable for interchangeable use in production environments.
