Key Parameters

Substitute Part Grouping Explanation

The MP2617BGL-Z has one parametric equivalent substitute: MP2617BGL-P. Both parts share identical electrical and thermal specifications, including single-cell lithium-ion charging capability, 4.2V battery pack voltage, 10V maximum supply voltage, programmable constant-current charging with timer control, and over-temperature fault protection. Both operate across the -40°C to 125°C temperature range and are housed in the 20-PowerTFQFN package (20-QFN 3x4 footprint). The substitution is valid based on matching battery chemistry, cell count, charging interface, protection features, and thermal performance. The only difference between these parts is the packaging format: MP2617BGL-Z is supplied in Cut Tape (CT) & Digi-Reel®, while MP2617BGL-P is supplied in Tape & Reel (TR).

Parameter Comparison

Engineering Selection Recommendations

Both MP2617BGL-Z and MP2617BGL-P are active products with full ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. Selection between these parts should be based on packaging and supply requirements. The MP2617BGL-Z in Cut Tape & Digi-Reel® format is appropriate for lower-volume applications or manual assembly processes, with significantly higher inventory availability (34,937 units). The MP2617BGL-P in Tape & Reel format is suitable for high-volume automated assembly operations, though current inventory is limited to 645 units. Both parts are electrically and thermally interchangeable with identical PCB footprints and pin configurations.

Frequently Asked Questions (FAQ)

Q: Are MP2617BGL-Z and MP2617BGL-P pin-for-pin compatible? A: Yes. Both parts use the 20-QFN (3x4) package with identical pin assignments and electrical characteristics. They share the same 20-PowerTFQFN footprint and require no circuit modifications for substitution.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging? A: Cut Tape & Digi-Reel® packaging is supplied on individual tape segments suitable for manual handling and lower-volume assembly. Tape & Reel packaging is supplied on continuous reels optimized for automated pick-and-place equipment in high-volume manufacturing. The electrical and mechanical specifications are identical.

Q: Can I use MP2617BGL-P as a direct replacement for MP2617BGL-Z in production? A: Yes, provided your assembly process supports Tape & Reel format. The parts are electrically and mechanically equivalent with no design changes required.

Q: Are both parts suitable for new designs? A: Yes. Both MP2617BGL-Z and MP2617BGL-P are active products with current manufacturer support and full compliance certifications (ROHS3, REACH unaffected).

Q: What are the key parameters that determine substitutability for this charger IC? A: Battery chemistry (Lithium Ion), cell count (1), output voltage (4.2V), maximum supply voltage (10V), charging method (Constant - Programmable), timer functionality, over-temperature protection, USB interface, operating temperature range (-40°C to 125°C), and package footprint (20-QFN 3x4) must all match for valid substitution.
