MP26053DQ-LF-Z Equivalent & Substitute Parts

Part Overview

The MP26053DQ-LF-Z is a single-cell lithium-ion/polymer battery charger IC manufactured by Monolithic Power Systems Inc. in a 10-QFN (3x3) package with exposed pad. This active product integrates programmable constant-current charging with timer-based fault protection and over-voltage detection. Finding equivalent and substitute parts becomes necessary when the primary part number is unavailable, when specific packaging requirements differ for assembly processes, or when inventory constraints require alternative sourcing options while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

All substitute parts maintain active product status with full ROHS3 compliance and REACH unaffected certification. Selection between MP26053DQ-LF-Z, MP2605DQ-LF-P, MP2605DQ-LF-Z, and MP26121DQ-LF-P is determined by assembly and procurement requirements:

MP2605DQ-LF-Z (Cut Tape): Highest inventory availability at 25,400 pieces. Suitable for high-volume automated pick-and-place assembly.
MP2605DQ-LF-P (Tape & Reel): 842 pieces in stock. Standard format for automated assembly lines with reel-fed component feeders.
MP26053DQ-LF-Z (Tube): 3,000 pieces in stock. Original specification with tube packaging.
MP26121DQ-LF-P (Tape & Reel): 1,317 pieces in stock. Alternative base product number with identical electrical and mechanical specifications.

All parts share identical electrical performance, thermal characteristics, and PCB footprint requirements. Packaging format selection depends on assembly equipment capability and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can MP2605DQ-LF-Z be used as a direct replacement for MP26053DQ-LF-Z?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: MP2605DQ-LF-Z uses Cut Tape while MP26053DQ-LF-Z uses Tube. PCB footprint and electrical performance are unchanged.

Q: What is the difference between MP2605DQ-LF-P and MP2605DQ-LF-Z?

A: Both parts are electrically identical. MP2605DQ-LF-P is supplied in Tape & Reel format; MP2605DQ-LF-Z is supplied in Cut Tape format. Selection depends on assembly equipment compatibility.

Q: Is MP26121DQ-LF-P compatible with designs using MP26053DQ-LF-Z?

A: Yes. MP26121DQ-LF-P maintains identical electrical specifications, operating temperature range, supply voltage, charge current rating, and 10-QFN (3x3) package footprint. The base product number differs, but functional equivalence is complete.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, with MSL 1 (Unlimited) moisture sensitivity level and EAR99 ECCN classification.

Q: Which substitute part should be selected for high-volume production?

A: MP2605DQ-LF-Z in Cut Tape format offers the highest inventory (25,400 pieces) and is optimized for automated high-speed pick-and-place assembly. MP2605DQ-LF-P in Tape & Reel format is suitable for standard reel-fed assembly lines.
