Substitute Part Grouping Explanation

Substitution eligibility for the BQ24314DSJR is determined by strict alignment of the following parameters:

• Battery Chemistry: Lithium Ion
• Fault Protection: Over Current, Over Temperature, Over/Under Voltage
• Operating Temperature Range: 0°C ~ 125°C (TJ)
• Package / Case: 12-VFDFN Exposed Pad
• Supplier Device Package: 12-VSON (4x3)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)
• REACH Status: REACH Unaffected

The substitute parts BQ24316DSJR and BQ24316DSJT meet all these criteria. Both are manufactured by Texas Instruments and provide identical functional protection capabilities, thermal specifications, and physical packaging requirements. The primary distinction between substitutes is product status and packaging format (Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both BQ24316DSJR and BQ24316DSJT are direct functional equivalents to the BQ24314DSJR. The primary selection criterion is product status: both substitute parts are classified as Active, ensuring long-term availability and supply chain continuity compared to the obsolete BQ24314DSJR.

From a compliance perspective, all three parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity specifications. No regulatory or environmental constraints differentiate the substitutes.

The choice between BQ24316DSJR and BQ24316DSJT depends on procurement requirements. Both parts are supplied in Tape & Reel format and carry identical electrical and thermal specifications. Inventory availability and lead time considerations should guide final selection between these two active alternatives.
