MP2637GR-P Equivalent & Substitute Parts

Part Overview

The MP2637GR-P is an active lithium-ion/polymer battery charger IC manufactured by Monolithic Power Systems Inc. in a 24-QFN (4x4) surface mount package. This single-cell charger integrates programmable constant-current charging with comprehensive fault protection including over-current, over-temperature, over-voltage, and short-circuit detection. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for consumer and industrial battery management applications requiring reliable charge control within the -20°C to 85°C operating range.

Substitute parts are identified when packaging format differs while all critical electrical and mechanical parameters remain identical, enabling component sourcing flexibility without design modification.

Substitute Part Grouping Explanation

The MP2637GR-Z qualifies as a parametric equivalent to the MP2637GR-P based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

  • Battery chemistry, cell count, and charge current specifications are identical
  • Maximum supply voltage and battery pack voltage ratings match
  • Fault protection features and programmable charging parameters are equivalent
  • Package type (24-PowerVFQFN) and mounting method (surface mount) are identical
  • Operating temperature range, RoHS compliance, and MSL rating are the same
  • Base product number (MP2637) is shared

The only difference between these parts is packaging format: MP2637GR-P is supplied in Tape & Reel (TR) format, while MP2637GR-Z is supplied in Cut Tape (CT) & Digi-Reel® format. This distinction affects procurement and handling but does not alter functional or electrical performance.

Engineering Selection Recommendations

Both MP2637GR-P and MP2637GR-Z are active products with identical electrical specifications and ROHS3 compliance. Selection between these parts is determined by procurement requirements and supply chain logistics rather than technical performance:

  • MP2637GR-P (Tape & Reel format) is suitable for high-volume automated assembly operations requiring continuous reel feeding
  • MP2637GR-Z (Cut Tape & Digi-Reel® format) provides flexibility for mixed-volume production runs and manual assembly workflows

Both parts maintain equivalent reliability, thermal performance, and fault protection capabilities across the specified operating temperature range. No design modifications are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can MP2637GR-Z be used as a direct replacement for MP2637GR-P in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). No PCB layout, schematic, or firmware changes are required.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) supplies components on continuous reels optimized for high-speed automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® provides pre-cut tape segments suitable for lower-volume assembly or manual handling. Both formats contain identical components in the same 24-PowerVFQFN package.

Q: Are there any thermal or performance differences between these part numbers?

A: No. Both parts share the same die, package type, and electrical specifications. Operating temperature range, charge current capability, and fault protection features are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP2637GR-P and MP2637GR-Z are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should I specify for a new design?

A: Either part is acceptable. Specify based on your manufacturing process: use MP2637GR-P for automated high-volume production with reel-fed equipment, or MP2637GR-Z for flexible sourcing and mixed-volume scenarios.
