Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPH6341-TL-EX is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• FET Type: P-Channel
• Drain to Source Voltage (Vdss): 30V minimum
• Continuous Drain Current (Id): 5A minimum at 25°C
• On-State Resistance (Rds On): 59mOhm maximum @ 3A, 10V
• Gate Charge (Qg): 10nC maximum @ 10V
• Maximum Gate-Source Voltage (Vgs): ±20V minimum
• Input Capacitance (Ciss): 430pF maximum @ 10V
• Power Dissipation: 1.6W maximum
• Operating Temperature: 150°C maximum

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SOT-23-6 or equivalent footprint
• Moisture Sensitivity Level: 1 (Unlimited)

The CPH6341-TL-W meets all specified electrical and mechanical parameters and is therefore a direct substitute for the CPH6341-TL-EX.

Parameter Comparison

Engineering Selection Recommendations

The CPH6341-TL-W is the direct substitute for the obsolete CPH6341-TL-EX. Both components are manufactured by onsemi and share identical electrical specifications across all critical parameters including voltage rating, current capacity, on-state resistance, gate charge, and thermal characteristics.

Product Status Consideration: The CPH6341-TL-EX is classified as Obsolete, while the CPH6341-TL-W maintains Active product status. This distinction is significant for long-term supply chain planning and design continuity.

Compliance and Certification: Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99). The CPH6341-TL-W is explicitly certified as ROHS3 Compliant, providing additional regulatory assurance for applications subject to RoHS requirements.

Packaging Difference: The primary distinction between these parts is packaging format. The CPH6341-TL-EX is supplied in Tube packaging, while the CPH6341-TL-W is supplied in Tape & Reel (TR) format. This difference affects handling, storage, and automated assembly processes but does not impact electrical performance or mechanical compatibility.

Footprint Compatibility: Both components utilize the SOT-23-6 surface mount package, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the CPH6341-TL-W be used as a direct replacement for the CPH6341-TL-EX in existing designs?

A: Yes. The CPH6341-TL-W is electrically and mechanically equivalent to the CPH6341-TL-EX. All electrical parameters, including voltage rating, current capacity, on-state resistance, and thermal characteristics, are identical. The SOT-23-6 package footprint is the same, requiring no PCB modifications.

Q: What is the difference between the Tube and Tape & Reel packaging formats?

A: Tube packaging supplies components in a plastic tube suitable for manual handling and small-volume applications. Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. The electrical and mechanical properties of the component itself are unchanged; only the delivery and handling method differs.

Q: Why is the CPH6341-TL-EX marked as Obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production of this specific part number. The CPH6341-TL-W, which shares identical electrical specifications, remains in active production and serves as the current equivalent.

Q: Are there any compliance differences between the two parts?

A: Both parts carry identical REACH and ECCN classifications. The CPH6341-TL-W is explicitly certified as ROHS3 Compliant. If RoHS compliance is a design requirement, the CPH6341-TL-W is the appropriate selection.

Q: Will switching from CPH6341-TL-EX to CPH6341-TL-W require circuit design changes?

A: No. The electrical specifications are identical, and the package footprint is the same. No circuit modifications or design changes are required.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both the CPH6341-TL-EX and CPH6341-TL-W carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the gate charge and input capacitance specifications identical?

A: Yes. Both components specify a maximum gate charge of 10nC @ 10V and maximum input capacitance of 430pF @ 10V. These parameters are critical for gate drive circuit design and are fully equivalent between the two parts.
