Engineering Selection Recommendations

CPH6350-TL-W (onsemi)

This substitute provides direct manufacturer continuity within the onsemi product line. It maintains identical package (SOT-23-6), mounting type (surface mount), and power dissipation (1.6W Ta) specifications. The CPH6350-TL-W offers higher voltage rating (30V vs. 20V), enabling use in higher voltage applications while maintaining 6A continuous drain current. On-state resistance is marginally higher (43 mOhm vs. 39 mOhm), representing a 10% increase. Gate charge increases to 13 nC, and maximum gate-source voltage increases to ±20V. This part is active and ROHS3 compliant, ensuring long-term availability and regulatory compliance.

BSL207SPH6327XTSA1 (Infineon Technologies)

This Infineon OptiMOS™ series device matches the 20V voltage rating and 6A current specification exactly. It is housed in a SOT-23-6 Thin / TSOT-23-6 package, maintaining footprint compatibility. On-state resistance is 41 mOhm at 6A and 4.5V, slightly higher than the main part. Power dissipation is rated at 2W (Ta), providing 25% additional thermal margin. Gate charge is 20 nC, approximately double the main part. Operating temperature range extends to -55°C, providing wider environmental coverage. This part is active, ROHS3 compliant, and carries the OptiMOS™ series designation indicating advanced process technology.

PMN30XPEX (Nexperia USA Inc.)

This Nexperia device operates at 20V with 5.3A continuous drain current, representing a 12% reduction in current capacity relative to the main part. On-state resistance is 34 mOhm at 5.3A and 4.5V, the lowest among all substitutes. Power dissipation is rated at 560mW (Ta) or 6.25W (Tc), providing superior thermal performance when case temperature measurement is available. Gate charge is 17 nC. Input capacitance is highest at 1465 pF. Package is SC-74 / SOT-457, differing from the main part's SOT-23-6, requiring PCB layout verification. This part is active and ROHS3 compliant.

Selection Basis:

All three substitutes are active products with REACH Unaffected and EAR99 ECCN status, matching the main part's compliance profile. CPH6350-TL-W is recommended for direct replacement when higher voltage tolerance is acceptable. BSL207SPH6327XTSA1 is recommended for applications requiring exact voltage and current matching with extended temperature range. PMN30XPEX is recommended for applications prioritizing low on-state resistance and thermal performance, provided PCB layout accommodates the SC-74 package.

Frequently Asked Questions (FAQ)

Q: Can the CPH6350-TL-W replace the CPH6347-TL-H in all applications?

A: The CPH6350-TL-W is electrically compatible for applications where the circuit operates at or below 20V. The higher 30V rating provides additional safety margin. On-state resistance increases by 10%, which may affect power dissipation in high-current applications. Gate charge increases from 10.5 nC to 13 nC, potentially affecting switching speed in high-frequency circuits. Verify circuit requirements before substitution.

Q: What is the primary difference between the BSL207SPH6327XTSA1 and the main part?

A: The BSL207SPH6327XTSA1 matches the 20V and 6A specifications exactly. Primary differences are higher gate charge (20 nC vs. 10.5 nC), higher power dissipation (2W vs. 1.6W), and extended operating temperature range (-55°C to 150°C vs. 150°C maximum). The OptiMOS™ series designation indicates advanced process technology from Infineon.

Q: Why does the PMN30XPEX have lower continuous drain current than the main part?

A: The PMN30XPEX is rated for 5.3A continuous drain current at 25°C ambient temperature, compared to 6A for the main part. This represents a 12% reduction in current capacity. However, this device offers superior on-state resistance (34 mOhm) and thermal performance (6.25W at case temperature). Applications requiring the full 6A rating should use CPH6350-TL-W or BSL207SPH6327XTSA1.

Q: Are all substitute parts in the same package as the CPH6347-TL-H?

A: CPH6350-TL-W and BSL207SPH6327XTSA1 are in SOT-23-6 packages, matching the main part. PMN30XPEX uses SC-74 / SOT-457 package, which differs in physical dimensions and pin layout. PCB layout verification is required before substituting PMN30XPEX.

Q: What is the impact of higher gate charge on circuit performance?

A: Gate charge affects the speed at which the MOSFET switches on and off. Higher gate charge (BSL207SPH6327XTSA1 at 20 nC, PMN30XPEX at 17 nC) requires more charge transfer from the gate driver, potentially increasing switching time and power loss in high-frequency applications. For low-frequency switching applications, this difference is negligible.

Q: Are all substitute parts RoHS compliant?

A: Yes. CPH6350-TL-W, BSL207SPH6327XTSA1, and PMN30XPEX are all ROHS3 compliant. The main part CPH6347-TL-H does not specify RoHS status, but all active substitutes meet current regulatory requirements.

Q: Can I use these substitutes interchangeably on the same PCB?

A: CPH6350-TL-W and BSL207SPH6327XTSA1 are directly interchangeable on PCBs designed for SOT-23-6 packages. PMN30XPEX requires PCB redesign due to its SC-74 / SOT-457 package. Verify gate driver compatibility and circuit timing requirements before substitution.

Q: What is the significance of the extended temperature range in BSL207SPH6327XTSA1 and PMN30XPEX?

A: Both devices operate from -55°C to 150°C, compared to the main part's 150°C maximum. Extended low-temperature operation is beneficial for applications in cold environments or aerospace applications. This does not affect room-temperature performance but provides additional environmental margin.
