VT1175MAFPR Equivalent & Substitute Parts

Part Overview

The VT1175MAFPR 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 VT1175MAFPR shares the same base product number (VT1175) with available substitute options, enabling direct functional replacement in applications requiring switching regulator functionality.

Substitute Part Grouping Explanation

Substitution of the VT1175MAFPR is determined by the following criteria:

• Base Product Number Match: Both the main part and substitute share the VT1175 base product number, confirming functional equivalence at the core IC level.
• Manufacturer Consistency: Substitute parts are sourced from the same manufacturer (Analog Devices Inc./Maxim Integrated), ensuring design continuity and technical support alignment.
• Category and Function: All parts maintain identical classification as Power Management (PMIC) components with Switching Regulator IC Output functionality.
• Compliance Standards: Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.
• Packaging Designation: Parts share the same SMD packaging classification, enabling direct board-level replacement without layout modifications.

Parameter Comparison

Engineering Selection Recommendations

The VT1175MAFPX is the manufacturer-recommended substitute for the obsolete VT1175MAFPR. Both parts maintain identical functional specifications, category classification, and regulatory compliance status (ROHS3 and REACH). The primary distinction is product lifecycle status: VT1175MAFPR is obsolete while VT1175MAFPX is active and available in production quantities (7200 pcs in stock versus 2085 pcs for the obsolete variant).

For new designs and ongoing procurement, VT1175MAFPX is the appropriate selection. For existing designs currently using VT1175MAFPR, direct substitution with VT1175MAFPX is supported by matching base product number, identical functional description, and equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can VT1175MAFPX directly replace VT1175MAFPR in existing designs?

A: Yes. Both parts share the VT1175 base product number and identical functional classification as Switching Regulator IC Output components. They maintain equivalent ROHS3 and REACH compliance status, supporting direct substitution.

Q: What is the difference between MSL 1 and MSL 3?

A: MSL (Moisture Sensitivity Level) indicates moisture exposure tolerance during storage and handling. VT1175MAFPR (MSL 1) has unlimited moisture tolerance, while VT1175MAFPX (MSL 3) requires controlled storage conditions not exceeding 168 hours at specified humidity levels. This affects component handling and storage protocols but does not impact functional performance in deployed applications.

Q: Why is VT1175MAFPR marked as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The active substitute VT1175MAFPX provides equivalent functionality and is the recommended path for continued component sourcing.

Q: Are packaging dimensions identical between these parts?

A: Both parts are classified as SMD (Surface Mount Device) with matching packaging designation. Specific dimensional data is not provided in the available parameters; refer to manufacturer datasheets for detailed package geometry if required for layout verification.

Q: What inventory status should influence procurement decisions?

A: VT1175MAFPX is the active part with 7200 pcs available in stock, providing reliable long-term availability. VT1175MAFPR inventory (2085 pcs) is limited and represents end-of-life stock. New procurement should prioritize VT1175MAFPX.
