Substitute Part Grouping Explanation

The VT1676SBFQX serves as the direct manufacturer-recommended substitute for the VT1676SBFQR. Substitution is based on the following criteria:

• Identical base product number (VT1676)
• Identical functional classification (Switching Regulator IC Output)
• Identical manufacturer (Analog Devices Inc./Maxim Integrated)
• Identical packaging designation
• Identical Moisture Sensitivity Level (MSL 1 - Unlimited)
• Identical HTSUS classification

The primary distinction is product status: VT1676SBFQR is obsolete while VT1676SBFQX is active, with improved RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The VT1676SBFQX is the direct replacement for VT1676SBFQR applications. Selection of VT1676SBFQX provides the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance meets current regulatory requirements for electronic components
• REACH Unaffected status confirms compliance with chemical substance regulations
• Identical electrical and mechanical specifications maintain form, fit, and function compatibility
• MSL 1 rating provides unlimited shelf life under standard storage conditions

For applications requiring RoHS non-compliant components, VT1676SBFQR inventory remains available; however, VT1676SBFQX is the recommended selection for new designs and production continuity.
