MP62341DS-1-LF-P Equivalent & Substitute Parts

Part Overview

The MP62341DS-1-LF-P is a Power Switch/Driver manufactured by Monolithic Power Systems Inc., designed for general-purpose switching applications with 1:2 input-to-output ratio configuration. This component operates as a high-side N/P-Channel driver with 1A maximum output current and integrated fault protection features including current limiting, over-temperature protection, reverse current blocking, and under-voltage lockout (UVLO).

The MP62341DS-1-LF-P carries a "Not For New Designs" product status, indicating that Monolithic Power Systems Inc. has designated this part as obsolete or end-of-life for new development. This status necessitates identification of functionally equivalent alternatives for ongoing production support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP62341DS-1-LF-P is determined by strict parametric matching across the following critical electrical and mechanical specifications:

Electrical Parameters (Must Match):

• Output Type: N/P-Channel
• Ratio - Input:Output: 1:2
• Output Configuration: High Side
• Current - Output (Max): 1A
• Voltage - Load: 2.7V ~ 5.5V
• Rds On (Typ): 85mOhm
• Input Type: Non-Inverting
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Features: Load Discharge, Status Flag
• Operating Temperature Range: -40°C ~ 85°C

Mechanical Parameters (Must Match):

• Supplier Device Package: 8-SOIC
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• MSL Rating: 2 (1 Year)

Only components meeting all specified parameters qualify as direct substitutes. The MP62340DS-1-LF-P satisfies all substitution criteria and is identified as the parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MP62340DS-1-LF-P is the direct parametric equivalent for the MP62341DS-1-LF-P. All electrical specifications, mechanical dimensions, package configuration, and compliance certifications are identical between the two components.

The primary distinction is product lifecycle status: the MP62341DS-1-LF-P is designated "Not For New Designs," while the MP62340DS-1-LF-P maintains "Active" status. This status difference indicates that the MP62340DS-1-LF-P is the current production part supported by Monolithic Power Systems Inc. for both new designs and ongoing production requirements.

Both components are ROHS3 compliant and carry identical MSL ratings of 2 (1 Year), confirming equivalent environmental and moisture handling requirements. Pin-to-pin compatibility, electrical performance, and thermal characteristics are identical, enabling direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the MP62340DS-1-LF-P be used as a direct replacement for the MP62341DS-1-LF-P in existing designs?

A: Yes. The MP62340DS-1-LF-P is a direct parametric equivalent. All electrical specifications, output ratings, fault protection features, operating temperature range, and package dimensions are identical. No circuit modifications or PCB layout changes are required.

Q: What is the significance of the "Not For New Designs" status on the MP62341DS-1-LF-P?

A: This designation indicates that Monolithic Power Systems Inc. has discontinued active support for the MP62341DS-1-LF-P in new product development. The MP62340DS-1-LF-P, with "Active" status, is the current production equivalent and should be used for all new designs and ongoing production.

Q: Are the 8-SOIC packages identical between these two parts?

A: Yes. Both components use the 8-SOIC (0.154", 3.90mm Width) package. Pin count, lead spacing, and physical dimensions are identical, confirming PCB footprint compatibility.

Q: Do both parts have the same RoHS and MSL compliance?

A: Yes. Both the MP62341DS-1-LF-P and MP62340DS-1-LF-P are ROHS3 compliant with MSL rating 2 (1 Year). Moisture handling and environmental compliance requirements are identical.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching: output type (N/P-Channel), input-to-output ratio (1:2), output configuration (High Side), maximum output current (1A), load voltage range (2.7V ~ 5.5V), on-resistance (85mOhm typical), fault protection features (current limiting, over-temperature, reverse current, UVLO), and operating temperature range (-40°C ~ 85°C).

Q: Is the MP62340DS-1-LF-P available in the same packaging format?

A: Yes. The MP62340DS-1-LF-P is supplied in Tape & Reel (TR) format, identical to the MP62341DS-1-LF-P, enabling compatibility with automated assembly processes.
