MP62550DGT-LF-P Equivalent & Substitute Parts

Part Overview

The MP62550DGT-LF-P is an N-Channel power switch driver IC manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a 1:1 high-side power switch with 1.5A output capability in a compact 6-TQFN (2x2) surface mount package. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design optimization calls for components with improved electrical characteristics while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP62550DGT-LF-P is determined by strict equivalence across the following critical parameters:

• Manufacturer: Monolithic Power Systems Inc. (same manufacturer ensures design continuity)
• Switch Type & Output Configuration: General Purpose N-Channel, High Side, 1:1 ratio
• Maximum Output Current: 1.5A
• Load Voltage Range: 2.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 6-WDFN Exposed Pad with Surface Mount capability
• Compliance Standards: RoHS3 Compliant, MSL 1 rating

The MP62551DGT-LF-P qualifies as a parametric equivalent substitute. Both parts share identical functional specifications, electrical ratings, and package geometry. The primary distinction lies in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and a minor improvement in on-resistance specification (88mOhm versus 100mOhm typical).

Parameter Comparison

Engineering Selection Recommendations

Both the MP62550DGT-LF-P and MP62551DGT-LF-P are active production components with full RoHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory compliance in consumer and industrial markets.

The MP62551DGT-LF-P presents a technical advantage through its reduced on-resistance specification (88mOhm typical versus 100mOhm), resulting in lower power dissipation and improved thermal performance under identical load conditions. This characteristic makes the MP62551DGT-LF-P the preferred selection for applications where thermal management or efficiency optimization is a design consideration.

Packaging format selection between Tape & Reel (MP62550DGT-LF-P) and Cut Tape & Digi-Reel (MP62551DGT-LF-P) depends on manufacturing process requirements. High-volume automated assembly operations typically utilize Tape & Reel format, while lower-volume or mixed-component runs may benefit from Cut Tape flexibility.

Both parts maintain identical electrical performance across all critical parameters: 1.5A maximum output current, 2.5V to 5.5V load voltage range, -40°C to 85°C operating temperature, and comprehensive fault protection including adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO).

Frequently Asked Questions (FAQ)

Q: Can MP62551DGT-LF-P directly replace MP62550DGT-LF-P in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package geometry, and pin configuration. The MP62551DGT-LF-P offers improved on-resistance (88mOhm vs. 100mOhm) with no design modifications required. Packaging format differs (Cut Tape vs. Tape & Reel), which affects procurement and assembly processes but not circuit functionality.

Q: What is the significance of the on-resistance difference between these parts?

A: The MP62551DGT-LF-P's lower on-resistance (88mOhm typical) reduces resistive power loss compared to the MP62550DGT-LF-P (100mOhm typical). At maximum 1.5A output current, this translates to lower junction temperature rise and improved efficiency. The difference is approximately 12% lower dissipation, which becomes significant in thermally constrained applications.

Q: Are there any differences in fault protection or safety features?

A: No. Both parts implement identical fault protection mechanisms: adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). Status flag output is present on both devices for system monitoring.

Q: What packaging considerations apply when switching between these part numbers?

A: MP62550DGT-LF-P arrives in Tape & Reel format suitable for high-speed automated pick-and-place assembly. MP62551DGT-LF-P is available in Cut Tape & Digi-Reel format, offering flexibility for lower-volume production or mixed-component kitting. Both use identical 6-WDFN Exposed Pad surface mount packages with 2x2mm footprint.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both MP62550DGT-LF-P and MP62551DGT-LF-P are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001 for export purposes.

Q: Which part should be selected for new design implementations?

A: The MP62551DGT-LF-P is the recommended selection for new designs due to superior on-resistance specification and improved thermal characteristics. Both parts are in active production with equivalent availability and pricing structures.
