3LP01SS-TL-E Equivalent & Substitute Parts

Part Overview

The 3LP01SS-TL-E is a P-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 100mA continuous drain current at 25°C. The device is housed in a 3-SSFP surface mount package and dissipates a maximum of 150mW. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3LP01SS-TL-E is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: P-Channel topology required
• Drain to Source Voltage (Vdss): Minimum 30V rating
• Continuous Drain Current (Id): Minimum 100mA at 25°C
• Power Dissipation: Minimum 150mW
• Gate Charge (Qg): Comparable switching characteristics
• Input Capacitance (Ciss): Low capacitance for fast switching response
• Vgs (Max): Gate voltage rating of ±10V or higher

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Moisture Sensitivity Level: MSL 1 or equivalent
• Regulatory Compliance: REACH Unaffected, EAR99 classification

The substitute parts identified (RSM002P03T2L and BSS84LT1G) meet or exceed the electrical requirements of the 3LP01SS-TL-E while maintaining surface mount compatibility. Package differences exist but do not preclude functional substitution in circuit applications where physical layout permits.

Parameter Comparison

Engineering Selection Recommendations

RSM002P03T2L (Rohm Semiconductor): This substitute provides electrical equivalence with the 3LP01SS-TL-E while offering active product status. The RSM002P03T2L matches the 30V Vdss rating and 150mW power dissipation specification. The continuous drain current rating of 200mA exceeds the 100mA requirement, providing design margin. The lower on-resistance (1.4 Ohm @ 200mA, 10V) compared to the original part (10.4 Ohm @ 50mA, 4V) indicates improved switching efficiency. The VMT3 package (SOT-723) is smaller than the 3-SSFP but maintains surface mount compatibility. RoHS3 compliance and REACH Unaffected status align with regulatory requirements.

BSS84LT1G (onsemi): This substitute exceeds the electrical specifications of the 3LP01SS-TL-E with a 50V Vdss rating and 130mA continuous drain current. The 225mW power dissipation rating provides additional thermal margin. The on-resistance of 10 Ohm @ 100mA, 5V is comparable to the original specification. The SOT-23-3 package is a standard surface mount form factor with wider industry availability. Extended operating temperature range (-55°C to 150°C) and ±20V Vgs rating provide greater design flexibility. Active product status and RoHS3 compliance ensure long-term procurement viability.

Both substitutes maintain MSL 1 classification, REACH Unaffected status, and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the RSM002P03T2L directly replace the 3LP01SS-TL-E in existing PCB layouts?

A: Electrical substitution is valid. However, the RSM002P03T2L uses a VMT3 (SOT-723) package while the 3LP01SS-TL-E uses a 3-SSFP (SC-81) package. Physical footprint differences require PCB layout modification. Pin configuration must be verified against device datasheets before implementation.

Q: What are the advantages of the BSS84LT1G over the RSM002P03T2L?

A: The BSS84LT1G offers higher voltage rating (50V vs. 30V), higher power dissipation capability (225mW vs. 150mW), and uses the more widely available SOT-23-3 package. The RSM002P03T2L provides lower on-resistance (1.4 Ohm vs. 10 Ohm) and matches the original 30V voltage specification more closely.

Q: Are package differences significant for substitution?

A: Package differences affect PCB layout and board assembly processes but do not impact electrical functionality. The 3-SSFP, VMT3, and SOT-23-3 packages are all surface mount technologies with different physical dimensions and pin configurations. Circuit schematic compatibility is maintained across all three packages.

Q: Does the higher Vgs (Max) rating of the substitutes affect circuit operation?

A: The substitutes feature ±20V Vgs (Max) compared to the original ±10V rating. This provides greater gate voltage tolerance and design margin. Existing gate drive circuits designed for ±10V operation remain compatible with the higher-rated substitutes.

Q: What is the impact of increased input capacitance in the substitutes?

A: The RSM002P03T2L and BSS84LT1G exhibit higher input capacitance (30 pF) compared to the 3LP01SS-TL-E (7.5 pF). This results in slower switching response and increased gate charge requirements. High-frequency switching applications may experience performance degradation. Low-frequency or DC switching applications are unaffected.

Q: Are all three parts compliant with current regulatory requirements?

A: Yes. The 3LP01SS-TL-E, RSM002P03T2L, and BSS84LT1G all carry REACH Unaffected status, EAR99 export classification, and MSL 1 moisture sensitivity rating. The RSM002P03T2L and BSS84LT1G additionally carry RoHS3 compliance certification.

Q: Why is the 3LP01SS-TL-E classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The RSM002P03T2L and BSS84LT1G are active products with ongoing manufacturing support and availability, making them suitable for new designs and long-term procurement.
