Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MD1730-I/M2 is determined by strict alignment with the following critical parameters:

• Manufacturer & Base Product Number: Both the main part and substitute must be manufactured by Microchip Technology and share the base product number MD1730
• Functional Category: Power Management (PMIC) for ultrasound imaging applications
• Electrical Specifications: Identical supply voltage range (4.75V ~ 5.25V) and operating temperature range (0°C ~ 85°C)
• Package Compatibility: Identical package type (36-VFQFN Exposed Pad) and supplier device package (36-SQFN 6x6) to ensure PCB footprint compatibility
• Compliance Standards: ROHS3 compliance and EAR99 export classification maintained

The MD1730-V/M2 qualifies as a manufacturer-recommended substitute based on these parameters. Both parts share identical electrical and mechanical specifications, differing only in product status and packaging format (Tray vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The MD1730-V/M2 is the manufacturer-recommended substitute for the obsolete MD1730-I/M2. Both components are manufactured by Microchip Technology and maintain identical electrical and mechanical specifications required for ultrasound imaging PMIC applications.

Product Status Consideration: The MD1730-I/M2 is classified as Obsolete, while the MD1730-V/M2 is Active. For new designs or ongoing production requiring this component family, the MD1730-V/M2 is the appropriate selection to ensure long-term supply chain availability and manufacturer support.

Compliance & Certification: Both parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory alignment for industrial and medical device applications.

Moisture Sensitivity: The MD1730-V/M2 has a higher Moisture Sensitivity Level (MSL 3, 168 Hours) compared to the MD1730-I/M2 (MSL 1, Unlimited). This difference requires attention to storage and handling procedures but does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MD1730-V/M2 be used as a direct replacement for the MD1730-I/M2?

A: Yes. Both components share identical electrical specifications (4.75V ~ 5.25V supply voltage, 0°C ~ 85°C operating temperature), mechanical package (36-VFQFN Exposed Pad, 36-SQFN 6x6), and functional application (Ultrasound Imaging PMIC). PCB footprint and electrical interface compatibility are maintained.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The MD1730-I/M2 (MSL 1) has unlimited shelf life under standard storage conditions. The MD1730-V/M2 (MSL 3) requires storage in controlled humidity conditions and has a 168-hour floor life after moisture exposure. Proper handling and storage procedures must be followed for the MD1730-V/M2 to maintain component reliability.

Q: Why is the MD1730-I/M2 classified as Obsolete?

A: The MD1730-I/M2 has reached end-of-life status. The MD1730-V/M2, classified as Active, is the current production equivalent and is recommended for all new designs and ongoing supply requirements.

Q: Are there differences in packaging that affect component selection?

A: The MD1730-I/M2 uses standard packaging, while the MD1730-V/M2 is supplied in Tray format. This difference affects order quantities and handling but does not impact electrical performance or PCB integration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MD1730-I/M2 and MD1730-V/M2 are ROHS3 compliant and classified as EAR99 for export purposes, ensuring regulatory alignment for industrial and medical device applications.
