5LP01C-TB-E MOSFET P-Channel Equivalent & Substitute Parts

Part Overview

The 5LP01C-TB-E is a P-Channel MOSFET manufactured by onsemi, rated for 50V drain-to-source voltage with 70mA continuous drain current at 25°C. The device is housed in a Surface Mount SC-59-3/CP3 package (TO-236-3/SOT-23-3) and dissipates a maximum of 250mW. This part is classified as Obsolete, making identification of equivalent and substitute components necessary for ongoing design support, production continuity, and system maintenance. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, and thermal characteristics while accommodating modern packaging and availability requirements.

Substitute Part Grouping Explanation

Substitution of the 5LP01C-TB-E is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: P-Channel topology required
• Drain to Source Voltage (Vdss): Minimum 50V rating
• Current - Continuous Drain (Id): Minimum 70mA at 25°C
• Power Dissipation: Minimum 250mW capability
• Operating Temperature: Maximum junction temperature of 150°C or higher
• Package Compatibility: Surface Mount TO-236-3/SOT-23-3 footprint
• Moisture Sensitivity Level: MSL 1 or equivalent

Substitute Part Identified:

The BSS84LT1G manufactured by onsemi meets all substitution criteria. This part maintains P-Channel topology, exceeds the 50V Vdss requirement, provides 130mA continuous drain current (exceeding the 70mA specification), and operates across an extended temperature range of −55°C to 150°C. The BSS84LT1G is housed in SOT-23-3 (TO-236) packaging, which is mechanically and electrically compatible with the original SC-59-3/CP3 footprint. The part is classified as Active product status with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory alignment.

Engineering Selection Recommendations

Primary Substitute: BSS84LT1G

The BSS84LT1G is the recommended substitute for the obsolete 5LP01C-TB-E based on the following engineering factors:

Product Status & Availability: The BSS84LT1G is classified as Active product status with 272,100 units in stock, ensuring immediate availability and long-term supply continuity. The original 5LP01C-TB-E is Obsolete, making the transition to an active equivalent essential for production planning and system support.

Electrical Compatibility: Both devices are P-Channel MOSFETs with identical 50V Vdss ratings. The BSS84LT1G provides 130mA continuous drain current, which exceeds the 70mA requirement of the original part, offering design margin for current-limited applications. The lower on-resistance (10 Ohm @ 100mA, 5V versus 23 Ohm @ 40mA, 4V) reduces power dissipation in switching applications.

Thermal & Environmental Compliance: The BSS84LT1G operates across −55°C to 150°C, extending the lower temperature range compared to the original specification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status. The BSS84LT1G carries ROHS3 compliance, aligning with modern regulatory requirements.

Package Compatibility: Both devices use identical Surface Mount TO-236-3/SOT-23-3 packaging, enabling direct footprint compatibility without PCB redesign.

Regulatory & Export Classification: Both parts share EAR99 ECCN classification and REACH Unaffected status, maintaining consistent export and compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the BSS84LT1G directly replace the 5LP01C-TB-E without circuit modification?

A: Yes. Both devices are P-Channel MOSFETs with 50V Vdss rating and identical TO-236-3/SOT-23-3 Surface Mount packaging. The BSS84LT1G meets or exceeds all electrical specifications of the original part, including continuous drain current (130mA versus 70mA), gate charge, and input capacitance. No circuit modification is required for direct substitution.

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

A: The primary differences are product status and electrical performance enhancements. The 5LP01C-TB-E is Obsolete, while the BSS84LT1G is Active. The BSS84LT1G provides higher continuous drain current (130mA versus 70mA), lower on-resistance (10 Ohm versus 23 Ohm), extended gate voltage rating (±20V versus ±10V), and expanded operating temperature range (−55°C to 150°C versus 150°C maximum). Power dissipation is comparable (225mW versus 250mW).

Q: Are there any application limitations when using the BSS84LT1G as a substitute?

A: No application limitations exist based on the provided electrical and mechanical parameters. The BSS84LT1G exceeds the original specifications in current capacity and thermal range, making it suitable for all applications previously served by the 5LP01C-TB-E. The higher input capacitance (30 pF versus 7.4 pF) may affect switching speed in high-frequency applications, but this is not a limitation for standard switching applications.

Q: Is the packaging footprint identical between the two parts?

A: Yes. Both the 5LP01C-TB-E and BSS84LT1G use Surface Mount TO-236-3/SOT-23-3 packaging with identical pin configuration and footprint. PCB layout and assembly processes require no modification.

Q: What is the moisture sensitivity level for the BSS84LT1G?

A: The BSS84LT1G carries MSL 1 (Unlimited) rating, identical to the original 5LP01C-TB-E. This classification indicates unlimited shelf life under controlled storage conditions without baking requirements.

Q: Are both parts compliant with REACH and export regulations?

A: Yes. Both the 5LP01C-TB-E and BSS84LT1G are REACH Unaffected and classified under ECCN EAR99, maintaining identical regulatory and export compliance status. The BSS84LT1G additionally carries ROHS3 compliance certification.

Q: What is the availability status of the BSS84LT1G?

A: The BSS84LT1G is classified as Active product status with 272,100 units in stock, ensuring immediate availability and long-term supply continuity. The original 5LP01C-TB-E is Obsolete with limited remaining inventory.
