Direct Equivalent Criteria:

• FET Type: P-Channel
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Flat Leads (6-MCPH)
• Drain to Source Voltage (Vdss): Equal or greater than 20V
• Current - Continuous Drain (Id) @ 25°C: Equal to or greater than 4.5A
• Rds On (Max): Equal to or lower than 49mOhm @ 3A, 4.5V
• Gate Charge (Qg): Equal to or lower than 7.3 nC @ 4.5V
• Input Capacitance (Ciss): Equal to or lower than 670 pF @ 10V
• Vgs (Max): Equal to or greater than ±10V

Similar Substitute Criteria: Parts meeting the above criteria with higher voltage or current ratings are acceptable substitutes provided they maintain electrical compatibility within the application circuit design parameters.

Parameter Comparison

Engineering Selection Recommendations

MCH6337-TL-W (Direct Equivalent): The MCH6337-TL-W is a direct electrical and mechanical equivalent to the MCH6337-TL-H. Both devices share identical electrical specifications including Vdss, Id, Rds On, gate charge, and input capacitance. The MCH6337-TL-W is classified as obsolete but carries ROHS3 compliance certification. This part is suitable for direct substitution in applications where the MCH6337-TL-H is specified, with 769 units available in inventory.

MCH6341-TL-W (Similar Substitute): The MCH6341-TL-W is an active product offering higher voltage (30V Vdss) and current (5A Id) ratings compared to the MCH6337-TL-H. This part meets or exceeds all critical electrical parameters: gate charge is 10 nC (within acceptable range), input capacitance is 430 pF (lower than the main part), and Rds On is 59 mOhm (acceptable at higher gate voltage). The MCH6341-TL-W is ROHS3 compliant and available in higher inventory (1990 units). This part is suitable for applications where the MCH6337-TL-H is specified, provided the circuit design accommodates the higher voltage rating and gate charge characteristics. The active product status of MCH6341-TL-W provides long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can MCH6337-TL-W be used as a direct replacement for MCH6337-TL-H?

A: Yes. The MCH6337-TL-W is electrically and mechanically identical to the MCH6337-TL-H across all specified parameters. Both devices are rated for 20V Vdss, 4.5A continuous drain current, 49 mOhm Rds On, and identical gate charge and input capacitance values. The 6-MCPH package and surface mount configuration are identical.

Q: What are the limitations of using MCH6341-TL-W as a substitute?

A: The MCH6341-TL-W has a higher Vdss rating (30V versus 20V) and higher gate charge (10 nC versus 7.3 nC). Applications operating at the maximum 20V specification of the original part will function correctly with the MCH6341-TL-W. However, circuits with tight gate drive timing requirements may experience different switching characteristics due to the increased gate charge. The higher Vdss rating does not create compatibility issues in applications designed for 20V operation.

Q: Are all substitute parts in the same package?

A: Yes. Both MCH6337-TL-W and MCH6341-TL-W use the 6-MCPH package with 6-SMD flat leads, identical to the MCH6337-TL-H. Pin-to-pin compatibility is maintained across all three parts.

Q: What is the difference between the MCH6337-TL-H and MCH6337-TL-W designations?

A: The MCH6337-TL-H and MCH6337-TL-W are both obsolete products with identical electrical specifications. The suffix designation (-H versus -W) indicates different manufacturing or packaging variants from onsemi, but electrical performance is equivalent.

Q: Why is MCH6341-TL-W recommended despite higher ratings?

A: The MCH6341-TL-W is an active product with confirmed long-term availability and higher inventory levels (1990 units). It meets all electrical requirements for applications designed around the MCH6337-TL-H specifications. The higher voltage and current ratings provide design margin without introducing incompatibility.

Q: Are there compliance differences between the substitute parts?

A: MCH6337-TL-W and MCH6341-TL-W both carry ROHS3 compliance certification. The MCH6337-TL-H does not specify RoHS status. All three parts are REACH Unaffected and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical across all parts.

Q: What is the inventory status for each part?

A: MCH6337-TL-H has 1310 units in stock. MCH6337-TL-W has 769 units in stock. MCH6341-TL-W has 1990 units in stock. All are listed as new original inventory.
