Parameter Comparison

Engineering Selection Recommendations

Both the MP2632GR-Z and MP2632GR-P are active products with identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on availability and supply chain requirements:

• MP2632GR-Z: 50,400 pieces in stock. Primary selection for new designs and production orders.
• MP2632GR-P: 1,513 pieces in stock. Alternative for inventory continuity or secondary sourcing.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical fault protection architecture. No functional or performance differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can MP2632GR-P replace MP2632GR-Z in existing designs?

A: Yes. Both parts are identical across all electrical parameters, package specifications, and compliance certifications. Direct substitution is valid without design modification.

Q: Are there differences in charging performance between these parts?

A: No. Maximum charging current (3A), battery pack voltage (4.45V), supply voltage (6V), and all fault protection features are identical.

Q: Do these parts require different PCB layouts?

A: No. Both use the 26-PowerVFQFN package with identical pin configurations and mounting requirements.

Q: What is the difference between the part numbers?

A: The suffix difference (Z vs. P) indicates packaging or tape reel configuration variants from Monolithic Power Systems Inc., but electrical and mechanical specifications remain identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MP2632GR-Z and MP2632GR-P are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Can I use either part for new production designs?

A: Yes. Both parts are active products with identical specifications. Selection should be based on availability and supply chain strategy.
