Substitute Part Grouping Explanation

The VT505FQX is identified as the manufacturer-recommended substitute for the VT505FQR. Both parts share the same base product number (VT505) and functional classification as Switching Regulator IC Output components within the Power Management category. Substitution eligibility is determined by the following parameters:

• Identical base product number (VT505)
• Matching functional description (IC REG - Switching Regulator IC Output)
• Equivalent category classification (Power Management/PMIC)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical REACH status (REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations
