Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ8636HGL-10-Z is determined by the following critical parameters:

• Input voltage range compatibility: 4.5V to 18V minimum requirement
• Output configuration: Single positive output with adjustable capability
• Topology: Buck (step-down) switching regulator with synchronous rectification
• Package form factor: 13-pin VFQFN surface mount
• Operating temperature range: -40°C to 125°C
• Output current capacity: Minimum 10A requirement for direct substitution

The UCD74106RGMR from Texas Instruments meets the core functional requirements of input voltage range, output configuration, topology, package type, and operating temperature. However, the output current specification differs, requiring evaluation based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

The UCD74106RGMR is an active product from Texas Instruments with ROHS3 compliance and unlimited moisture sensitivity rating, matching the environmental and regulatory requirements of the MPQ8636HGL-10-Z. Both devices operate across the identical input voltage range (4.5V to 18V) and temperature range (-40°C to 125°C).

The primary distinction is output current capacity: the UCD74106RGMR delivers 6A versus the 10A specification of the MPQ8636HGL-10-Z. Selection between these devices depends on application current requirements. The UCD74106RGMR also features a higher maximum switching frequency (up to 2MHz versus 200kHz to 1MHz), which may provide advantages in applications requiring smaller passive component footprints.

Both devices employ synchronous rectification and are packaged in 13-pin VFQFN form factors with exposed pads. The physical package dimensions differ slightly (3x3mm versus 3x4mm), which may affect PCB layout considerations.

Frequently Asked Questions (FAQ)

Q: Can the UCD74106RGMR directly replace the MPQ8636HGL-10-Z in all applications?

A: Direct replacement is possible only in applications where the output current requirement does not exceed 6A. The UCD74106RGMR is rated for 6A maximum output current, while the MPQ8636HGL-10-Z is rated for 10A. Applications requiring the full 10A output current of the original part require alternative solutions.

Q: Are the input voltage ranges identical between these devices?

A: Yes. Both the MPQ8636HGL-10-Z and UCD74106RGMR accept input voltages from 4.5V to 18V and operate across the same temperature range of -40°C to 125°C.

Q: What are the package differences between these parts?

A: Both devices use 13-pin VFQFN packages with exposed pads. The MPQ8636HGL-10-Z uses a 3x4mm package, while the UCD74106RGMR uses a 3x3mm package. This dimensional difference may require PCB layout modifications.

Q: Do both devices support adjustable output voltage?

A: The MPQ8636HGL-10-Z explicitly supports adjustable output from 0.611V to 13V. The UCD74106RGMR output type specification is not provided in the available data. Output voltage configuration must be verified against the UCD74106RGMR datasheet before implementation.

Q: What is the significance of the product status difference?

A: The MPQ8636HGL-10-Z is marked as Not For New Designs, indicating Monolithic Power Systems Inc. is not recommending this part for new product development. The UCD74106RGMR carries Active status from Texas Instruments, indicating ongoing support and availability for new designs.

Q: Are the switching frequency ranges compatible?

A: The MPQ8636HGL-10-Z operates at 200kHz to 1MHz, while the UCD74106RGMR operates up to 2MHz. The UCD74106RGMR's higher maximum frequency may enable different filter designs and component selections in the power supply circuit.
