• Gate Voltage (Vgs Max): ±10V or greater
• Operating Temperature: 150°C or higher

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package compatibility: TO-236-3 (SC-59, SOT-23-3) or equivalent footprint

Substitute Categories:

Direct Equivalent: CPH3348-TL-W is an onsemi part with identical electrical specifications and package, differing only in packaging format (Cut Tape vs. standard packaging).

Similar Substitutes: RTR030P02TL (Rohm Semiconductor) and RZR025P01TL (Rohm Semiconductor) provide functional equivalence with variations in voltage rating, current capacity, and package type. These parts meet or exceed the electrical requirements of the CPH3348-TL-E within their specified operating parameters.

Engineering Selection Recommendations

CPH3348-TL-W (Direct Equivalent)

The CPH3348-TL-W is the primary equivalent for the CPH3348-TL-E. Both parts share identical electrical specifications, package type (TO-236-3, SC-59, SOT-23-3), and thermal characteristics. The CPH3348-TL-W differs only in packaging format (Cut Tape). Although both parts carry Obsolete product status, the CPH3348-TL-W maintains higher current inventory (17,411 pcs) compared to the CPH3348-TL-E (56,300 pcs). The CPH3348-TL-W is ROHS3 Compliant, providing regulatory advantage for new applications.

RTR030P02TL (Rohm Semiconductor)

The RTR030P02TL is an Active product from Rohm Semiconductor with superior supply availability (125,300 pcs in stock). This part exceeds the voltage rating of the CPH3348-TL-E (20V vs. 12V) while maintaining the same 3A continuous drain current and 1W power dissipation. The RTR030P02TL is housed in an SC-96 package, requiring PCB layout modification. Gate charge is higher (9.3 nC vs. 5.6 nC), and input capacitance is doubled (840 pF vs. 405 pF). The RTR030P02TL is ROHS3 Compliant and carries Active product status, ensuring long-term availability.

RZR025P01TL (Rohm Semiconductor)

The RZR025P01TL is a Rohm Semiconductor part with Not For New Designs product status. This part maintains the 12V voltage rating and 1W power dissipation of the CPH3348-TL-E but is rated for 2.5A continuous drain current (0.5A below the original specification). The RZR025P01TL is housed in an SC-96 package. Gate charge (13 nC) and input capacitance (1350 pF) are significantly higher than the CPH3348-TL-E. This part is ROHS3 Compliant but carries Not For New Designs status, limiting its suitability for new production.

Frequently Asked Questions (FAQ)

Q: Can the CPH3348-TL-W be used as a direct replacement for the CPH3348-TL-E?

A: Yes. The CPH3348-TL-W is electrically and functionally identical to the CPH3348-TL-E. Both parts have identical Vdss (12V), Id (3A), Rds On (70 mOhm), gate charge (5.6 nC), and operating temperature (150°C). The only difference is packaging format (Cut Tape vs. standard). Both parts use the same TO-236-3 (SC-59, SOT-23-3) package footprint.

Q: What are the key differences between the CPH3348-TL-E and the RTR030P02TL?

A: The RTR030P02TL has a higher Vdss rating (20V vs. 12V), which provides additional voltage margin in applications. Both parts maintain 3A continuous drain current and 1W power dissipation. However, the RTR030P02TL uses a different package (SC-96 vs. TO-236-3), requiring PCB layout changes. Gate charge and input capacitance are higher in the RTR030P02TL, which may affect switching speed and drive circuit requirements.

Q: Is the RZR025P01TL suitable as a substitute for the CPH3348-TL-E?

A: The RZR025P01TL is not recommended as a primary substitute. While it maintains the 12V voltage rating, its continuous drain current rating is 2.5A, which is 0.5A below the CPH3348-TL-E specification. Applications requiring the full 3A rating will not be adequately served by this part. Additionally, the RZR025P01TL carries Not For New Designs status.

Q: Do all substitute parts have the same package footprint?

A: No. The CPH3348-TL-E and CPH3348-TL-W use the TO-236-3 (SC-59, SOT-23-3) package. The RTR030P02TL and RZR025P01TL use the SC-96 package, which has a different footprint. PCB layout modification is required when substituting with Rohm Semiconductor parts.

Q: Are all substitute parts RoHS compliant?

A: The CPH3348-TL-W, RTR030P02TL, and RZR025P01TL are all ROHS3 Compliant. The original CPH3348-TL-E does not specify RoHS status. All parts are REACH Unaffected and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute part has the best long-term availability?

A: The RTR030P02TL from Rohm Semiconductor carries Active product status with the highest inventory (125,300 pcs). Both onsemi parts (CPH3348-TL-E and CPH3348-TL-W) are classified as Obsolete. The RZR025P01TL carries Not For New Designs status, limiting future availability.

Q: What is the impact of higher gate charge in substitute parts?

A: The RTR030P02TL has gate charge of 9.3 nC (vs. 5.6 nC in the CPH3348-TL-E), and the RZR025P01TL has 13 nC. Higher gate charge requires more drive current from the gate driver circuit and increases switching time. Applications with tight timing requirements or limited gate drive capability may require circuit redesign.

Q: Can the CPH3348-TL-E be used in applications rated for 20V?

A: No. The CPH3348-TL-E is rated for maximum 12V drain-to-source voltage. Using it in 20V applications exceeds the device rating and will result in failure. The RTR030P02TL is rated for 20V and is suitable for such applications, provided other electrical parameters are compatible.
