Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5LP01C-TB-H is determined by strict electrical and mechanical compatibility across the following parameters:

Electrical Compatibility Criteria:

• FET Type: P-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Substitute must equal or exceed 50V
• Continuous Drain Current (Id): Substitute must meet or exceed 70mA at 25°C
• Power Dissipation: Substitute must support thermal requirements of 250mW or greater
• Gate Voltage (Vgs): Substitute maximum rating must accommodate ±10V operation
• On-Resistance (Rds On): Substitute performance must not degrade circuit switching characteristics

Mechanical Compatibility Criteria:

• Package Type: Surface Mount in TO-236-3/SOT-23-3 form factor
• Mounting Type: Surface Mount configuration
• Pin Configuration: Three-pin configuration (SC-59-3/CP3 equivalent)

Compliance Criteria:

• REACH Status: REACH Unaffected or compliant
• Moisture Sensitivity Level (MSL): Level 1 (Unlimited)
• ECCN Classification: EAR99

The BSS84LT1G meets all substitution criteria and is classified as an active product with enhanced electrical performance and extended operating temperature range.

Engineering Selection Recommendations

BSS84LT1G as Primary Substitute:

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

1. Product Status: The BSS84LT1G is classified as Active, ensuring long-term availability and supply chain continuity compared to the obsolete 5LP01C-TB-H.

2. Electrical Performance: The BSS84LT1G exceeds the electrical requirements of the 5LP01C-TB-H across all critical parameters. Continuous drain current is rated at 130mA versus 70mA, providing 86% additional current capacity. On-resistance is reduced to 10Ohm at 100mA/5V compared to 23Ohm at 40mA/4V, resulting in improved switching efficiency and reduced power dissipation in practical applications.

3. Voltage Ratings: The BSS84LT1G maintains the 50V Vdss rating and extends the maximum gate voltage rating to ±20V, providing greater design flexibility and gate drive margin compared to the ±10V limit of the 5LP01C-TB-H.

4. Temperature Range: The BSS84LT1G specifies an extended operating temperature range of -55°C to 150°C, compared to the 5LP01C-TB-H specification of 150°C maximum. This provides improved performance in low-temperature environments.

5. Compliance and Certifications: Both devices maintain REACH Unaffected status, MSL Level 1 (Unlimited) rating, and EAR99 ECCN classification, ensuring regulatory compatibility.

6. Package Compatibility: Both devices utilize identical Surface Mount packaging (TO-236-3/SOT-23-3), enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the BSS84LT1G be used as a direct replacement for the 5LP01C-TB-H without circuit modification?

A: Yes. The BSS84LT1G is electrically and mechanically compatible with the 5LP01C-TB-H. Both devices share identical Vdss (50V), package type (TO-236-3/SOT-23-3), and pin configuration. The BSS84LT1G exceeds the current and power dissipation requirements of the 5LP01C-TB-H, making it suitable for direct substitution in existing designs.

Q: What are the key electrical differences between the 5LP01C-TB-H and BSS84LT1G?

A: The primary differences are: (1) Continuous drain current: BSS84LT1G is rated at 130mA versus 70mA for the 5LP01C-TB-H; (2) On-resistance: BSS84LT1G is 10Ohm at 100mA/5V versus 23Ohm at 40mA/4V for the 5LP01C-TB-H; (3) Maximum gate voltage: BSS84LT1G supports ±20V versus ±10V for the 5LP01C-TB-H; (4) Operating temperature range: BSS84LT1G extends to -55°C minimum versus no specified minimum for the 5LP01C-TB-H.

Q: Are there any package or pinout differences between these devices?

A: No. Both the 5LP01C-TB-H and BSS84LT1G use identical Surface Mount packaging designated as TO-236-3, SC-59, or SOT-23-3. Pin configuration and footprint are identical, allowing direct PCB substitution without layout changes.

Q: Why is the 5LP01C-TB-H classified as obsolete?

A: The 5LP01C-TB-H is listed as obsolete by the manufacturer, indicating it is no longer in active production. The BSS84LT1G is the active equivalent product from onsemi and is recommended for new designs and ongoing production support.

Q: Does the BSS84LT1G meet the same compliance requirements as the 5LP01C-TB-H?

A: Yes. Both devices maintain REACH Unaffected status, MSL Level 1 (Unlimited) rating, and EAR99 ECCN classification. Compliance and regulatory requirements are equivalent between the two parts.

Q: What is the impact of the higher input capacitance (Ciss) of the BSS84LT1G?

A: The BSS84LT1G specifies 30pF input capacitance at 5V compared to 7.4pF at 10V for the 5LP01C-TB-H. Higher input capacitance may require slightly increased gate drive current in high-frequency switching applications. However, this difference is typically negligible in standard switching circuits and does not prevent substitution.

Q: Can the BSS84LT1G handle the same power dissipation as the 5LP01C-TB-H?

A: The BSS84LT1G is rated for 225mW maximum power dissipation compared to 250mW for the 5LP01C-TB-H. This 10% reduction is offset by the BSS84LT1G's lower on-resistance, which typically results in lower actual power dissipation in practical switching applications. Both devices are suitable for equivalent thermal management requirements.
