Substitute Part Grouping Explanation

Substitute parts for the MCP73114T-0NSI/MF are qualified based on strict electrical and mechanical parameter equivalence:

Direct Packaging Substitute: MCP73114-0NSI/MF maintains identical electrical specifications and mechanical compatibility with the main part. The only difference is packaging format (Tube vs. Tape & Reel), which does not affect functional performance or board-level integration.

Parametric Equivalent: MCP73113T-06SI/MF is classified as a parametric equivalent based on matching core electrical parameters: single-cell lithium ion/polymer chemistry, 1.1A maximum charging current, 4.2V battery pack voltage, 6.5V maximum supply voltage, identical package type (10-VFDFN Exposed Pad), surface mount mounting, and equivalent operating temperature range. The base product number differs (MCP73113 vs. MCP73114), indicating a related but distinct device variant within the Microchip charger IC family that maintains functional compatibility for single-cell lithium battery applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MCP73114T-0NSI/MF, MCP73114-0NSI/MF, and MCP73113T-06SI/MF—are active products from Microchip Technology with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

MCP73114-0NSI/MF is the direct substitute when packaging format flexibility is required, as it provides identical electrical performance with alternative distribution packaging (Tube instead of Tape & Reel).

MCP73113T-06SI/MF is the parametric equivalent option when the MCP73114 variant is unavailable, maintaining all critical electrical specifications for single-cell lithium ion/polymer battery charging applications. Selection between MCP73114 and MCP73113 base product families should be confirmed against application-specific control interface requirements and firmware compatibility, as these represent distinct device variants.

Frequently Asked Questions (FAQ)

Q: Can MCP73114-0NSI/MF be used as a direct replacement for MCP73114T-0NSI/MF?

A: Yes. Both parts are electrically identical with matching electrical specifications, package type, and performance characteristics. The difference is packaging format: MCP73114T-0NSI/MF is supplied in Tape & Reel, while MCP73114-0NSI/MF is supplied in Tube. Board-level integration and functional performance are equivalent.

Q: What makes MCP73113T-06SI/MF a parametric equivalent?

A: MCP73113T-06SI/MF matches all critical electrical parameters: single-cell lithium ion/polymer chemistry, 1.1A maximum charging current, 4.2V battery pack voltage, 6.5V maximum supply voltage, identical 10-VFDFN package, and equivalent operating temperature range. The base product number differs, indicating a related variant within the Microchip charger IC family.

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

A: All three parts carry identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited), and active product status. No compliance or certification differences exist.

Q: Does packaging format affect PCB assembly or performance?

A: No. Tape & Reel and Tube packaging formats contain identical components and do not affect PCB assembly compatibility, soldering process, or electrical performance. The choice is driven by supply chain and inventory management requirements.

Q: Should I verify compatibility before substituting MCP73113T-06SI/MF for MCP73114T-0NSI/MF?

A: Confirm that your application firmware and control interface are compatible with the MCP73113 variant, as this represents a distinct device family within Microchip's charger IC portfolio. Electrical specifications are equivalent, but device-specific control features may differ.
