Substitute Part Grouping Explanation

Substitution relationships are established based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical battery chemistry (Lithium Ion/Polymer), single-cell configuration, 4.2V battery pack voltage, 6V maximum supply voltage, and -40°C to 85°C operating temperature range.

Package Compatibility: All parts use the 10-VFDFN Exposed Pad package in 10-DFN (3x3) form factor with surface mount mounting type, ensuring PCB layout and thermal management compatibility.

Charging Specifications: Substitute parts feature programmable constant charging current with over-temperature fault protection. Charge current ratings are either 1.1A or 1.0A, both within the functional range for single-cell lithium ion/polymer applications.

Compliance & Certification: All parts maintain ROHS3 compliance, MSL Level 1 rating, and identical ECCN/HTSUS classifications.

Packaging Format Variations: Substitutes differ in distribution packaging (Tape & Reel, Tube, or Cut Tape & Digi-Reel) but maintain identical component specifications.

Engineering Selection Recommendations

All substitute parts are active products from Microchip Technology with ROHS3 compliance and MSL Level 1 certification, meeting the same regulatory and environmental standards as the primary part MCP73833T-GPI/MF.

Direct Substitutes (Identical Specifications): MCP73833-GPI/MF, MCP73833T-AMI/MF, MCP73833T-CNI/MF, and MCP73834T-FCI/MF maintain 1.1A maximum charge current and are functionally equivalent to the main part. Selection among these options depends on packaging availability and inventory requirements.

Parametric Equivalent: MCP73833T-FCI/MF operates at 1.0A maximum charge current. This part is suitable for applications where the lower charge current specification meets system requirements.

Packaging Considerations: The main part MCP73833T-GPI/MF is supplied in Tape & Reel format. Tube packaging (MCP73833-GPI/MF) and Cut Tape & Digi-Reel formats (MCP73833T-AMI/MF, MCP73833T-CNI/MF, MCP73833T-FCI/MF, MCP73834T-FCI/MF) offer alternative distribution methods for different procurement workflows and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MCP73833T-FCI/MF replace MCP73833T-GPI/MF in my design?

A: MCP73833T-FCI/MF is a parametric equivalent with identical electrical specifications except for maximum charge current (1.0A vs. 1.1A). It is suitable for replacement if your application requires charging current at or below 1.0A. Both parts share the same package, voltage ratings, temperature range, and protection features.

Q: What is the difference between MCP73833-GPI/MF and MCP73833T-GPI/MF?

A: These parts are electrically identical with matching 1.1A charge current, 4.2V battery voltage, and 10-VFDFN package. The primary difference is packaging format: MCP73833-GPI/MF is supplied in Tube packaging, while MCP73833T-GPI/MF is supplied in Tape & Reel. Component specifications and performance are equivalent.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the 10-VFDFN Exposed Pad package in 10-DFN (3x3) form factor with surface mount mounting. PCB footprints, thermal pad dimensions, and pin configurations are identical across all listed parts.

Q: What is the difference between MCP73833 and MCP73834 series?

A: Both MCP73833T-GPI/MF and MCP73834T-FCI/MF are single-cell lithium ion/polymer chargers with identical electrical specifications, package type, and operating parameters. The base product number difference (MCP73833 vs. MCP73834) reflects internal Microchip product line designation but does not affect functional equivalence for this application.

Q: Which substitute part has the highest inventory availability?

A: MCP73834T-FCI/MF has the highest inventory at 35,200 pieces, followed by MCP73833T-FCI/MF at 32,888 pieces. Both are supplied in Cut Tape & Digi-Reel format.

Q: Do all parts meet the same compliance standards?

A: Yes. All listed parts maintain ROHS3 compliance, MSL Level 1 rating, and identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
