Substitute Part Grouping Explanation

Substitution eligibility for the BQ25100BYFPR is determined by strict parametric equivalence across all critical electrical and mechanical specifications. The substitute part BQ25100BYFPT shares identical parameters with the main part across all categories: battery chemistry (Lithium Ion/Polymer), cell count (1), maximum charge current (250mA), battery pack voltage (4.284V), maximum supply voltage (6.45V), operating temperature range (-5°C ~ 125°C), package type (6-XFBGA, DSBGA), mounting configuration (Surface Mount), interface standard (USB), fault protection mechanisms (Over Temperature, Over Voltage, Short Circuit), and compliance certifications (ROHS3, MSL 1). The only distinction between these parts is the packaging designation suffix (BYFPR vs. BYFPT), which reflects different tape and reel configurations from the same manufacturer without affecting functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both BQ25100BYFPR and BQ25100BYFPT are active production components from Texas Instruments with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement availability and supply chain requirements. The BQ25100BYFPR currently maintains higher inventory levels (21,447 units) compared to BQ25100BYFPT (1,540 units), making it the preferred choice for immediate availability. Both parts carry identical electrical specifications, thermal ratings, and protection mechanisms, ensuring functional interchangeability in single-cell lithium-ion/polymer battery charging applications. The packaging designation difference (BYFPR vs. BYFPT) relates to tape and reel configuration only and does not affect circuit performance or PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Are BQ25100BYFPR and BQ25100BYFPT electrically identical?

A: Yes. Both parts share identical electrical specifications including maximum charge current (250mA), battery pack voltage (4.284V), maximum supply voltage (6.45V), operating temperature range (-5°C ~ 125°C), and fault protection features (Over Temperature, Over Voltage, Short Circuit).

Q: What is the difference between BQ25100BYFPR and BQ25100BYFPT?
