Substitute Part Grouping Explanation

Substitution of the VT1185SFQR is determined by alignment across the following critical parameters:

• Base Product Number: Both the main part and substitute maintain the VT1185 base product number, indicating functional equivalence within the VT1185 product family
• Category & Function: Both are classified as Power Management (PMIC) components with identical functional description (IC REG - Switching Regulator IC Output)
• Manufacturer: Both are manufactured by Analog Devices Inc./Maxim Integrated, ensuring design consistency and supply chain continuity
• Moisture Sensitivity Level: Both maintain MSL 1 (Unlimited), confirming identical moisture handling requirements
• Packaging: Both share identical packaging specifications

The substitute part VT1185SFQX represents the active production equivalent within the VT1185 product family, with enhanced compliance status suitable for current design implementations.

Parameter Comparison

Engineering Selection Recommendations

The VT1185SFQX is the manufacturer-recommended substitute for the obsolete VT1185SFQR. Both components share identical functional specifications, packaging, and moisture sensitivity characteristics, establishing direct substitutability within the VT1185 product family.

The VT1185SFQX provides enhanced compliance status through ROHS3 compliance and REACH Unaffected certification, making it suitable for applications requiring current regulatory adherence. The VT1185SFQX maintains active production status with significantly higher inventory availability (36200 pieces), ensuring supply chain continuity for new designs and ongoing production requirements.

Selection between these parts should be based on regulatory compliance requirements and procurement timeline. The VT1185SFQX is the appropriate choice for designs requiring RoHS3 compliance and REACH compliance verification.

Frequently Asked Questions (FAQ)

Q: Can the VT1185SFQX directly replace the VT1185SFQR in existing designs?

A: Yes. Both components share identical base product number (VT1185), functional description (Switching Regulator IC Output), packaging specifications, and moisture sensitivity level (MSL 1). The VT1185SFQX is the manufacturer-recommended active equivalent.

Q: What is the primary difference between VT1185SFQR and VT1185SFQX?

A: The VT1185SFQX is the active production variant with ROHS3 compliance and REACH Unaffected certification. The VT1185SFQR is obsolete and RoHS non-compliant. Functionally and mechanically, both components are equivalent.

Q: Are there packaging differences between these parts?

A: No. Both the VT1185SFQR and VT1185SFQX maintain identical packaging specifications.

Q: Which part should be selected for new designs?

A: The VT1185SFQX should be selected for new designs. It maintains active production status, higher inventory availability, and current regulatory compliance (ROHS3, REACH Unaffected).

Q: Is the VT1185SFQR still available for procurement?

A: The VT1185SFQR is listed as obsolete with 2400 pieces available as new original stock. However, the VT1185SFQX is the recommended alternative with significantly higher inventory (36200 pieces) and active production status.
