Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPH3216-TL-EX are classified based on strict electrical and mechanical parameter compatibility. The substitution logic is determined by the following critical parameters:

Primary Substitution Criteria:

• Transistor Type: NPN (required match)
• Voltage - Collector Emitter Breakdown: minimum 50V
• Current - Collector (Ic) (Max): minimum 1A
• Package / Case: TO-236-3, SC-59, or SOT-23-3 (physical compatibility)
• Mounting Type: Surface Mount (required match)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: MSL 1 (required match)

Secondary Compatibility Parameters:

• Power dissipation capability
• Transition frequency
• DC Current Gain (hFE)
• Vce Saturation characteristics

Parts are grouped into two categories: Parametric Equivalents (identical electrical specifications with different packaging) and Similar Alternatives (compatible electrical parameters within acceptable ranges for the application class).

Engineering Selection Recommendations

CPH3216-TL-E (onsemi)

The CPH3216-TL-E is a parametric equivalent to the CPH3216-TL-EX with identical electrical specifications. The primary distinction is packaging format: CPH3216-TL-E is supplied in Tape & Reel (TR) configuration versus the main part's unspecified packaging. Both parts maintain 50V breakdown voltage, 1A collector current, 900mW power dissipation, and 420MHz transition frequency. This part is suitable for direct substitution in high-volume manufacturing environments where tape and reel packaging is standard. Product status is Active with full ROHS3 compliance and MSL 1 rating.

DNBT8105-7 (Diodes Incorporated)

The DNBT8105-7 is a similar alternative with compatible electrical parameters for general-purpose switching applications. This part exceeds the voltage specification at 60V breakdown (versus 50V required), supporting applications with higher voltage margins. However, power dissipation is reduced to 600mW and transition frequency is 150MHz, making this part suitable for lower-frequency switching circuits. The DC current gain minimum is 100 @ 500mA, 5V, which is lower than the main part. Product status is Active with ROHS3 compliance and MSL 1 rating. Inventory availability is significantly higher at 110,300 pieces.

FMMTL619TA (Diodes Incorporated)

The FMMTL619TA is a similar alternative with enhanced current capability at 1.25A maximum collector current, exceeding the 1A specification of the main part. Voltage rating matches at 50V breakdown. Power dissipation is reduced to 500mW with transition frequency of 180MHz. The DC current gain is 200 @ 500mA, 5V, meeting the gain specification. This part is suitable for applications requiring higher current capacity within the same voltage envelope. Product status is Active with ROHS3 compliance and MSL 1 rating. Inventory availability is 68,350 pieces.

PBSS4160T,215 (Nexperia USA Inc.)

The PBSS4160T,215 is a similar alternative with 60V breakdown voltage, providing higher voltage margin than the main part's 50V specification. Collector current rating matches at 1A. Power dissipation is reduced to 400mW with transition frequency of 220MHz. The DC current gain is 200 @ 500mA, 5V. Vce saturation is 250mV @ 100mA, 1A, which is higher than the main part's 190mV specification. This part is suitable for applications where higher voltage tolerance is beneficial. Product status is Active with ROHS3 compliance and MSL 1 rating. Inventory availability is 5,700 pieces.

PBSS4160TVL (Nexperia USA Inc.)

The PBSS4160TVL is a similar alternative with identical electrical specifications to PBSS4160T,215, including 60V breakdown voltage, 1A collector current, and 400mW power dissipation. The DC current gain specification differs at 250 @ 1mA, 5V, indicating enhanced gain at lower current levels. This part is suitable for low-signal amplification applications requiring higher current gain. Product status is Active with ROHS3 compliance and MSL 1 rating. Inventory availability is 1,038 pieces.

Frequently Asked Questions (FAQ)

Q: Can CPH3216-TL-E be used as a direct replacement for CPH3216-TL-EX?

A: Yes. The CPH3216-TL-E is a parametric equivalent with identical electrical specifications: 50V breakdown voltage, 1A collector current, 900mW power dissipation, 420MHz transition frequency, and 200 hFE minimum gain. The only difference is packaging format (Tape & Reel versus unspecified). Both parts are onsemi products with Active status, ROHS3 compliance, and MSL 1 rating.

Q: What are the voltage limitations when substituting with DNBT8105-7?

A: The DNBT8105-7 has a 60V breakdown voltage specification, which exceeds the CPH3216-TL-EX requirement of 50V. This provides a 10V safety margin. However, the transition frequency is reduced to 150MHz (versus 420MHz), making this part unsuitable for high-frequency switching applications above 150MHz.

Q: Is FMMTL619TA suitable for applications requiring 1A collector current?

A: Yes. The FMMTL619TA supports 1.25A maximum collector current, exceeding the 1A requirement. However, power dissipation is limited to 500mW (versus 900mW for the main part), and transition frequency is 180MHz. Applications must operate within these power and frequency constraints.

Q: What is the difference between PBSS4160T,215 and PBSS4160TVL?

A: Both parts share identical voltage (60V), current (1A), and power (400mW) specifications. The difference is in DC current gain measurement conditions: PBSS4160T,215 is specified at 200 hFE @ 500mA, 5V, while PBSS4160TVL is specified at 250 hFE @ 1mA, 5V. PBSS4160TVL exhibits higher gain at lower current levels, making it more suitable for low-signal amplification.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use TO-236-3, SC-59, or SOT-23-3 package designations, which share identical physical dimensions and pin configurations. PCB footprints are interchangeable without layout modifications.

Q: What is the impact of reduced power dissipation in substitute parts?

A: Substitute parts with lower power ratings (DNBT8105-7 at 600mW, FMMTL619TA at 500mW, PBSS4160 series at 400mW) require thermal management consideration in high-power applications. The CPH3216-TL-EX at 900mW provides greater thermal headroom. Applications must verify that actual power dissipation remains within the substitute part's rating.

Q: Can PBSS4160 series parts be used in high-frequency switching circuits?

A: The PBSS4160 series has a transition frequency of 220MHz, which is lower than the CPH3216-TL-EX at 420MHz. These parts are suitable for switching frequencies up to approximately 220MHz. Applications requiring operation above 220MHz should use the main part or CPH3216-TL-E equivalent.

Q: What inventory considerations apply to these substitute parts?

A: CPH3216-TL-E has 4,571 pieces in stock. DNBT8105-7 has the highest availability at 110,300 pieces. FMMTL619TA has 68,350 pieces. PBSS4160T,215 has 5,700 pieces. PBSS4160TVL has the lowest availability at 1,038 pieces. Inventory levels should be verified for production volume requirements.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All parts listed are ROHS3 compliant and REACH unaffected. All parts carry EAR99 export classification and are classified under HTSUS code 8541.21.0075. Moisture sensitivity level is MSL 1 (unlimited) for all parts, requiring no special storage or handling conditions.
