MPQ8632GLE-4-P Equivalent & Substitute Parts

Part Overview

The MPQ8632GLE-4-P is a buck switching regulator IC manufactured by Monolithic Power Systems, classified as a Power Management (PMIC) component. This device functions as a step-down converter with positive adjustable output, delivering 4A maximum output current across a single output channel. The part is actively produced and available in high volume (937 pcs in stock), packaged in 16-PowerVFQFN surface mount configuration with Tape & Reel delivery.

Substitute parts are identified when electrical and mechanical parameters align within the allowed specifications for buck regulator topology, enabling direct or near-direct replacement in circuit designs. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative packaging formats are required for manufacturing optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPQ8632GLE-4-P are qualified based on the following electrical and mechanical compatibility criteria:

Core Substitution Parameters:

• Topology: Buck (step-down) switching regulator
• Output Configuration: Positive adjustable
• Number of Outputs: Single output
• Input Voltage Range: 4.5V to 18V minimum compatibility
• Output Voltage Range: 0.611V to 13V minimum compatibility
• Package Type: 16-PowerVFQFN (3x4) surface mount
• Synchronous Rectifier: Present
• Operating Temperature Range: -40°C to 125°C (TJ)

Allowable Variation: Output current rating may exceed the primary part specification (4A) without compromising substitution validity, as higher current capability maintains backward compatibility in applications requiring equal or lower current delivery.

Three substitute parts meet these criteria: MP8760GLE-Z, MPQ8632GLE-6-P, and MPQ8632GLE-6-Z. All three share identical electrical specifications with the primary part except for increased output current capacity (6A versus 4A) and variations in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

MPQ8632GLE-6-P and MPQ8632GLE-6-Z are the preferred substitute options. Both parts maintain Active product status, ensuring continued manufacturing support and long-term availability. These parts share the same base product number (MPQ8632) as the primary part, indicating design lineage and validated compatibility. The 6A output current rating provides increased headroom for applications originally designed for 4A operation. Both parts are ROHS3 compliant with MSL 1 rating, matching the primary part's environmental and reliability specifications.

Selection between MPQ8632GLE-6-P and MPQ8632GLE-6-Z depends on packaging format requirements: MPQ8632GLE-6-P is supplied in Cut Tape format, while MPQ8632GLE-6-Z is supplied in Cut Tape with Digi-Reel® format. Inventory availability is significantly higher for MPQ8632GLE-6-Z (18,300 pcs) compared to MPQ8632GLE-6-P (5,963 pcs).

Secondary Substitute (Legacy Status):

MP8760GLE-Z is electrically equivalent but carries Not For New Designs product status. This part is suitable only for sustaining production of existing designs or as a temporary solution when primary substitutes are unavailable. The different base product number (MP8760 versus MPQ8632) indicates a separate product line, though electrical specifications remain compatible. This part is supplied in Cut Tape with Digi-Reel® format with high inventory availability (5,569 pcs).

Frequently Asked Questions (FAQ)

Q: Can MPQ8632GLE-6-P or MPQ8632GLE-6-Z be used as direct replacements for MPQ8632GLE-4-P?

A: Yes. Both parts are direct substitutes. The 6A output current rating is a superset of the 4A requirement, maintaining full electrical compatibility. All other parameters—input voltage range, output voltage range, switching frequency, synchronous rectifier presence, operating temperature, and package type—are identical. No circuit modifications are required.

Q: What is the difference between MPQ8632GLE-6-P and MPQ8632GLE-6-Z?

A: Both parts are electrically identical with 6A output current. The difference is packaging format: MPQ8632GLE-6-P uses Cut Tape delivery, while MPQ8632GLE-6-Z uses Cut Tape with Digi-Reel® format. MPQ8632GLE-6-Z has significantly higher inventory (18,300 pcs versus 5,963 pcs). Select based on your manufacturing equipment compatibility and supply chain requirements.

Q: Why is MP8760GLE-Z marked as "Not For New Designs"?

A: MP8760GLE-Z carries legacy product status, indicating Monolithic Power Systems has transitioned this product line. While electrically compatible and suitable for sustaining existing production, it is not recommended for new circuit designs. Use MPQ8632GLE-6-P or MPQ8632GLE-6-Z for new applications.

Q: Are all substitute parts in the same 16-PowerVFQFN package?

A: Yes. All substitute parts use the 16-PowerVFQFN (3x4) surface mount package, ensuring PCB layout and footprint compatibility with the primary part. No redesign of the circuit board is necessary.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the primary part's environmental and regulatory compliance. REACH status is unaffected for all parts.

Q: What is the inventory status of each substitute?

A: MPQ8632GLE-6-Z has the highest availability (18,300 pcs), followed by MPQ8632GLE-6-P (5,963 pcs) and MP8760GLE-Z (5,569 pcs). The primary part MPQ8632GLE-4-P has 937 pcs in stock. Verify current inventory with your supplier before finalizing procurement decisions.
