VT1185MFPR Equivalent & Substitute Parts

Part Overview

The VT1185MFPR is a Switching Regulator IC Output manufactured by Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) component. This part is currently marked as obsolete, necessitating identification of active equivalent alternatives for ongoing design support and procurement. The VT1185MFPR shares the same base product number (VT1185) with active variants, making substitution feasible within the same product family.

Substitute Part Grouping Explanation

Substitution of the VT1185MFPR is determined by the following criteria:

• Base Product Number Match: Both the obsolete part and substitute share the VT1185 base product number, confirming functional equivalence within the Analog Devices Inc./Maxim Integrated product line.
• Category Alignment: Both parts are classified as Power Management (PMIC) components with identical functional descriptions (Switching Regulator IC Output).
• Compliance Consistency: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility.
• Manufacturer Continuity: Both parts are manufactured by the same entity, guaranteeing design and performance consistency.

The primary distinction lies in product status: the VT1185MFPR is obsolete, while the substitute is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The VT1185MFPX is the manufacturer-recommended substitute for the obsolete VT1185MFPR. Both parts maintain identical regulatory compliance (ROHS3 and REACH Unaffected status) and functional specifications as Switching Regulator IC Output components within the VT1185 product family.

The VT1185MFPX is currently in active production status with significantly higher inventory availability (16622 units versus 1240 units for the obsolete variant), ensuring reliable procurement for new designs and production requirements.

The MSL rating difference (MSL 1 versus MSL 3) reflects standard industry variations in moisture sensitivity classification and does not affect functional equivalence for switching regulator applications.

Frequently Asked Questions (FAQ)

Q: Can the VT1185MFPX directly replace the VT1185MFPR in existing designs?

A: Yes. Both parts share the VT1185 base product number and are functionally equivalent Switching Regulator IC Output components from the same manufacturer. Regulatory compliance (ROHS3 and REACH Unaffected) is maintained across both variants.

Q: What is the significance of the different MSL ratings?

A: The MSL 1 rating of the VT1185MFPR indicates unlimited moisture sensitivity protection, while the MSL 3 rating of the VT1185MFPX specifies 168-hour protection. This difference reflects standard manufacturing variations and does not impact functional performance in switching regulator applications.

Q: Why is the VT1185MFPR marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. The VT1185MFPX remains in active production and is the recommended alternative for continued component sourcing.

Q: Are there packaging differences between these parts?

A: Both parts are classified as IC REG SMD (Surface Mount Device) components. Packaging specifications are not differentiated in the provided technical parameters.

Q: What inventory considerations should guide part selection?

A: The VT1185MFPX offers substantially higher inventory availability (16622 units) compared to the obsolete VT1185MFPR (1240 units), making it the preferred choice for production and long-term supply chain stability.
