MCP73833-AMI/MF Equivalent & Substitute Parts

Part Overview

The MCP73833-AMI/MF is a single-cell lithium ion/polymer battery charger IC manufactured by Microchip Technology, housed in a 10-DFN (3x3) surface mount package. This active product functions as a power management integrated circuit (PMIC) with programmable charging current and over-temperature fault protection. The device operates across a -40°C to 85°C temperature range and supports a maximum supply voltage of 6V with a 4.2V battery pack output.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for supply chain optimization, or when design flexibility demands component sourcing from multiple inventory channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MCP73833-AMI/MF is based on strict electrical and mechanical parameter equivalence:

Direct Substitute (Packaging Variant):

• MCP73833T-AMI/MF differs only in packaging format (Cut Tape & Digi-Reel® versus Tube), maintaining identical electrical specifications and the same base product number (MCP73833).

Parametric Equivalents (Same Base Product - MCP73833 Series):

• MCP73833-BZI/MF
• MCP73833-CNI/MF
• MCP73833-FCI/MF
• MCP73833-GPI/MF

These parts share the identical base product number MCP73833 and maintain all critical electrical parameters: 1.1A maximum charge current, 4.2V battery pack voltage, 6V maximum supply voltage, -40°C to 85°C operating temperature range, and 10-DFN (3x3) package configuration. Variations exist only in packaging format (Tube) and inventory levels.

Parametric Equivalents (Related Base Product - MCP73834 Series):

• MCP73834-CNI/MF
• MCP73834-FCI/MF
• MCP73834-GPI/MF

These parts share the MCP73834 base product number while maintaining all critical electrical parameters identical to MCP73833-AMI/MF: 1.1A maximum charge current, 4.2V battery pack voltage, 6V maximum supply voltage, -40°C to 85°C operating temperature range, and 10-DFN (3x3) package configuration.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status with Microchip Technology and comply with ROHS3 and REACH requirements. Selection between MCP73833 and MCP73834 base product families is determined by application-specific requirements not detailed in the provided parameters; both families deliver identical electrical performance for single-cell lithium ion/polymer charging at 1.1A maximum current.

MCP73833T-AMI/MF offers the highest inventory availability (15,920 units) with Cut Tape & Digi-Reel® packaging, suitable for high-volume automated assembly operations. MCP73833-AMI/MF and MCP73833-FCI/MF provide Tube packaging with substantial inventory (9,189 and 3,932 units respectively) for manual or semi-automated placement.

All parts share identical moisture sensitivity level (MSL 1 - Unlimited), eliminating bake-out requirements and simplifying logistics. The 10-VFDFN Exposed Pad package configuration remains consistent across all substitutes, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can MCP73833T-AMI/MF replace MCP73833-AMI/MF in production?

A: Yes. Both parts are electrically identical with the same base product number (MCP73833). The only difference is packaging format: MCP73833T-AMI/MF uses Cut Tape & Digi-Reel® while MCP73833-AMI/MF uses Tube. PCB assembly compatibility is maintained; packaging selection depends on your manufacturing process (automated versus manual placement).

Q: Are MCP73833 and MCP73834 series interchangeable?

A: Yes, for the electrical parameters provided. Both series deliver 1.1A maximum charge current, 4.2V battery pack voltage, 6V maximum supply voltage, and -40°C to 85°C operating temperature range in identical 10-DFN (3x3) packages. Functional differences between base product families are not specified in the provided parameters.

Q: What is the significance of the suffix codes (AMI, BZI, CNI, FCI, GPI)?

A: Suffix codes indicate packaging format and/or test/qualification variants within the same base product. All listed suffixes maintain identical electrical specifications and package type (10-VFDFN Exposed Pad). Selection is based on inventory availability and packaging format preference (Tube versus Cut Tape & Digi-Reel®).

Q: Do all substitutes require the same PCB footprint?

A: Yes. All parts use the 10-VFDFN Exposed Pad package configuration, ensuring identical PCB footprint and assembly compatibility without layout modifications.

Q: Are there any compliance differences between substitute parts?

A: No. All parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity level. Compliance certifications are uniform across all substitutes.

Q: Which substitute offers the best inventory availability?

A: MCP73833T-AMI/MF provides the highest inventory level at 15,920 units in Cut Tape & Digi-Reel® packaging. For Tube packaging, MCP73833-AMI/MF (9,189 units) and MCP73834-FCI/MF (4,396 units) offer substantial availability.
