Substitute Part Grouping Explanation

Substitution of P-Channel MOSFETs is determined by the following critical parameters:

Electrical Compatibility Criteria:

Drain-to-Source Voltage (Vdss) must equal or exceed the main part specification (20V minimum)
Continuous Drain Current (Id) must meet or exceed application requirements
On-Resistance (Rds On) characteristics must be compatible with circuit performance
Gate Threshold Voltage (Vgs(th)) must fall within acceptable operating ranges
Maximum Gate Voltage (Vgs Max) must accommodate drive circuit specifications
Power Dissipation rating must support thermal requirements

Mechanical Compatibility Criteria:

Package type must be SOT-23-3 or equivalent TO-236-3 footprint
Mounting type must be Surface Mount
Pin configuration must be identical (Gate, Drain, Source)

Compliance Criteria:

RoHS3 compliance required
Moisture Sensitivity Level (MSL) of 1 or better
REACH Unaffected status

The substitute parts FDN336P and NVR1P02T1G meet the electrical voltage and package requirements but differ in current ratings and on-resistance characteristics. Selection depends on specific circuit current demands and thermal constraints.

Engineering Selection Recommendations

BSH205G2VL (Primary Selection)

The BSH205G2VL is the primary specification for applications requiring 2.3A continuous drain current with 170 mOhm on-resistance at 4.5V gate drive. This part carries AEC-Q101 automotive qualification and is suitable for automotive-grade switching applications. The device is active and in production with high inventory availability (8645 pcs).

FDN336P (Current-Limited Substitute)

The FDN336P is suitable for applications where continuous drain current requirements do not exceed 1.3A. This part provides equivalent voltage rating (20V Vdss) and compatible SOT-23-3 packaging. The on-resistance specification (200 mOhm @ 1.3A, 4.5V) is slightly higher than the main part. FDN336P does not carry automotive qualification; use is restricted to non-automotive applications. High inventory availability (107100 pcs) supports supply continuity.

NVR1P02T1G (Automotive-Qualified Substitute)

The NVR1P02T1G is suitable for applications where continuous drain current requirements do not exceed 1.0A. This part carries AEC-Q101 automotive qualification matching the main part. The device provides equivalent voltage rating (20V Vdss) and compatible SOT-23-3 packaging. On-resistance specification (180 mOhm @ 1.5A, 10V) is comparable to the main part. Gate threshold voltage is higher (2.3V @ 250µA), requiring higher drive voltage. Inventory availability (12900 pcs) supports production requirements.

Selection Logic:

For applications requiring 2.3A continuous current with automotive qualification: use BSH205G2VL
For applications requiring up to 1.3A continuous current in non-automotive environments: FDN336P is acceptable
For applications requiring up to 1.0A continuous current with automotive qualification: NVR1P02T1G is acceptable

Frequently Asked Questions (FAQ)

Q: Can FDN336P replace BSH205G2VL in all applications?

A: No. FDN336P is limited to 1.3A continuous drain current compared to 2.3A for BSH205G2VL. Applications requiring current above 1.3A cannot use FDN336P. Additionally, FDN336P lacks AEC-Q101 automotive qualification; use is restricted to non-automotive applications.

Q: What is the primary difference between NVR1P02T1G and BSH205G2VL?

A: The primary difference is continuous drain current rating. NVR1P02T1G is rated for 1.0A maximum, while BSH205G2VL is rated for 2.3A. Both parts carry AEC-Q101 automotive qualification and use identical SOT-23-3 packaging. NVR1P02T1G has higher gate threshold voltage (2.3V vs. 950mV), requiring higher drive voltage.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use SOT-23-3 (TO-236-3) packaging with identical pin configuration: Gate, Drain, and Source. Direct PCB footprint compatibility is confirmed.

Q: Which substitute part has the lowest on-resistance?

A: BSH205G2VL has the lowest on-resistance at 170 mOhm (@ 2A, 4.5V). NVR1P02T1G is 180 mOhm (@ 1.5A, 10V), and FDN336P is 200 mOhm (@ 1.3A, 4.5V). On-resistance comparisons must account for different measurement conditions (current and gate voltage).

Q: Can I use these parts interchangeably in automotive applications?

A: Only BSH205G2VL and NVR1P02T1G are suitable for automotive applications, both carrying AEC-Q101 qualification. FDN336P lacks automotive qualification and must not be used in automotive-grade designs. Current rating compatibility must also be verified for the specific application.

Q: What is the impact of different gate threshold voltages?

A: Gate threshold voltage (Vgs(th)) determines the minimum gate-source voltage required to turn the device on. BSH205G2VL has 950 mV threshold, FDN336P has 1.5V, and NVR1P02T1G has 2.3V. Higher threshold voltages require higher drive voltages to achieve full on-state conduction. Drive circuit compatibility must be verified when substituting parts with different threshold specifications.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts (BSH205G2VL, FDN336P, and NVR1P02T1G) are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: What is the significance of input capacitance differences?

A: Input capacitance (Ciss) affects gate charge and switching speed. BSH205G2VL has 418 pF (@ 10V), FDN336P has 330 pF (@ 10V), and NVR1P02T1G has 165 pF (@ 5V). Lower capacitance results in faster switching and lower gate drive power requirements. Measurement conditions differ between parts; direct comparison requires normalization to identical test conditions.
