5LP01M-TL-E MOSFET P-Channel Equivalent & Substitute Parts

Part Overview

The 5LP01M-TL-E is a P-Channel MOSFET manufactured by onsemi, rated for 50V drain-to-source voltage with 70mA continuous drain current and 150mW power dissipation in a surface mount MCP package. This device is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating available packaging options.

Engineering Selection Recommendations

The BSS84AKW,115 is a qualified substitute for the obsolete 5LP01M-TL-E based on the following factors:

Electrical Compatibility: The substitute part maintains the 50V Vdss rating and exceeds the 70mA continuous drain current requirement with a 150mA rating. Power dissipation capability is increased to 260mW at ambient temperature, providing additional thermal margin. On-resistance is reduced to 7.5Ohm, improving efficiency in switching applications.

Package Compatibility: Both devices utilize SC-70 and SOT-323 surface mount packages, ensuring mechanical and thermal interface compatibility with existing PCB layouts and thermal management solutions.

Product Status and Compliance: The BSS84AKW,115 is classified as active product status, ensuring long-term availability and supply chain continuity. The device is AEC-Q101 qualified and ROHS3 compliant, meeting automotive and environmental regulatory requirements. Both parts carry REACH Unaffected status and EAR99 ECCN classification.

Thermal and Operational Range: The substitute part supports an extended operating temperature range of -55°C to 150°C junction temperature, compared to the main part's 150°C maximum. This provides improved performance margin across industrial and automotive temperature profiles.

Frequently Asked Questions (FAQ)

Q: Can the BSS84AKW,115 be used as a direct replacement for the 5LP01M-TL-E in existing designs?

A: Yes. Both devices are P-Channel MOSFETs with identical 50V Vdss ratings, compatible SC-70/SOT-323 packages, and surface mount configurations. The substitute part exceeds the original device specifications in continuous drain current (150mA vs. 70mA) and power dissipation (260mW vs. 150mW), making it functionally compatible for the same application space.

Q: What are the key electrical differences between these parts?

A: The BSS84AKW,115 provides superior performance characteristics: 2.14× higher continuous drain current, 1.73× greater power dissipation capability, 69% lower on-resistance, and 75% lower gate charge. These improvements result in reduced switching losses and improved thermal performance in the same package footprint.

Q: Are there package considerations when substituting these parts?

A: Both parts use identical SC-70 and SOT-323 surface mount packages. No PCB layout modifications are required. Thermal interface characteristics remain compatible, though the substitute part's improved power dissipation capability may reduce thermal management requirements in some applications.

Q: What compliance certifications apply to the substitute part?

A: The BSS84AKW,115 is AEC-Q101 qualified for automotive applications, ROHS3 compliant for environmental regulations, and carries REACH Unaffected status. Both parts share EAR99 ECCN classification and MSL 1 moisture sensitivity rating.

Q: Is the extended temperature range of the substitute part significant?

A: The BSS84AKW,115 supports -55°C to 150°C junction temperature operation, compared to the 5LP01M-TL-E's 150°C maximum. This extended lower temperature limit provides improved performance margin in industrial and automotive applications operating below 0°C ambient conditions.

Q: How do gate charge specifications affect circuit design?

A: The substitute part's 0.35nC gate charge at 5V is significantly lower than the original 1.4nC at 10V. Lower gate charge reduces driver circuit power consumption and enables faster switching transitions, benefiting high-frequency switching applications and reducing electromagnetic interference.
