CPH3216-TL-E Equivalent & Substitute Parts

Part Overview

The CPH3216-TL-E is an NPN bipolar junction transistor manufactured by onsemi, rated for 50V collector-emitter breakdown voltage and 1A maximum collector current. This surface mount device operates at a transition frequency of 420MHz with a maximum power dissipation of 900mW and is housed in a TO-236-3 (SOT-23-3) package. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements permit operation within specified electrical and mechanical parameter ranges, or when supply chain considerations necessitate alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPH3216-TL-E is determined by the following criteria:

Primary Substitution Parameters:

• Transistor Type: NPN (required match)
• Voltage - Collector Emitter Breakdown (Max): 50V or greater
• Current - Collector (Ic) (Max): 1A or greater
• Mounting Type: Surface Mount (required match)
• Package / Case: TO-236-3, SC-59, or SOT-23-3 (required match)
• Operating Temperature (Max): 150°C or greater
• RoHS Status: ROHS3 Compliant (required match)

Secondary Consideration Parameters:

• Power - Max: 900mW or greater preferred
• Frequency - Transition: 420MHz or greater preferred
• Vce Saturation characteristics
• DC Current Gain (hFE) specifications

Parts are grouped into two categories:

Direct Substitutes: Parts meeting all primary parameters with electrical characteristics within acceptable operating ranges for the CPH3216-TL-E application.

Similar Substitutes: Parts meeting primary parameters but with reduced ratings in secondary parameters (lower power dissipation, lower transition frequency, or reduced collector current). These require application-level verification that the reduced specifications do not impact circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred):

The FMMTL619TA (Diodes Incorporated) provides the closest electrical match to the CPH3216-TL-E. This part exceeds the primary specifications with 1.25A maximum collector current and 50V breakdown voltage, maintaining the same package form factor (TO-236-3, SC-59, SOT-23-3). Both devices are ROHS3 compliant with unlimited MSL rating and active production status. The FMMTL619TA is suitable for direct substitution in applications where the CPH3216-TL-E is specified.

Acceptable Substitutes (Application-Dependent):

The 2SCR513RTL (Rohm Semiconductor) meets all primary parameters with 1A collector current and 50V breakdown voltage in the same package. However, the SC-96 package designation differs from the standard SOT-23-3 footprint, requiring PCB layout verification. Power dissipation is reduced to 500mW and transition frequency to 360MHz.

The DNBT8105-7 and FMMT451TA (both Diodes Incorporated) provide 1A collector current capability with 60V breakdown voltage, exceeding the CPH3216-TL-E voltage rating. Both use the correct TO-236-3/SOT-23-3 package. Power dissipation is reduced to 600mW and 500mW respectively, with transition frequencies of 150MHz. These parts are suitable for applications where lower frequency operation is acceptable.

Limited Substitutes (Reduced Ratings):

The 2SD1484KT146Q and 2SD1484KT146R (Rohm Semiconductor) have reduced collector current ratings of 500mA maximum, limiting their use to applications requiring less than 500mA. Power dissipation is 200mW and transition frequency is 250MHz. These parts are suitable only when circuit design permits operation at reduced current levels.

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and active production status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 2SD1484KT146R replace the CPH3216-TL-E in all applications?

A: No. The 2SD1484KT146R has a maximum collector current of 500mA, compared to the CPH3216-TL-E rating of 1A. Substitution is limited to applications where circuit design operates at or below 500mA collector current. Power dissipation is also reduced to 200mW versus 900mW.

Q: Is the 2SCR513RTL package compatible with CPH3216-TL-E PCB layouts?

A: The 2SCR513RTL uses an SC-96 package, while the CPH3216-TL-E uses TO-236-3 (SOT-23-3). These packages have different footprints and pin configurations. PCB layout modification is required for substitution.

Q: What is the primary difference between FMMTL619TA and CPH3216-TL-E?

A: The FMMTL619TA exceeds the CPH3216-TL-E specifications in collector current (1.25A versus 1A) and maintains the same 50V breakdown voltage and TO-236-3 package. Transition frequency is lower at 180MHz versus 420MHz, and power dissipation is reduced to 500mW. The FMMTL619TA is suitable for direct substitution when lower frequency operation is acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the CPH3216-TL-E.

Q: Can DNBT8105-7 be used in place of CPH3216-TL-E?

A: The DNBT8105-7 meets primary substitution parameters with 1A collector current and TO-236-3 package compatibility. However, the 60V breakdown voltage exceeds the CPH3216-TL-E specification, and transition frequency is reduced to 150MHz. Substitution is acceptable for applications where lower frequency operation does not impact circuit performance.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts, including the CPH3216-TL-E, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part has the highest collector current rating?

A: The FMMTL619TA has the highest collector current rating at 1.25A maximum, exceeding the CPH3216-TL-E specification of 1A.

Q: Are there package footprint differences between substitute parts?

A: Yes. The 2SCR513RTL uses SC-96 package, which differs from the TO-236-3/SOT-23-3 footprint used by the CPH3216-TL-E and all other substitute parts. All other substitute parts use compatible TO-236-3 or SOT-23-3 packages.
