CPH3223-TL-E Equivalent & Substitute Parts

Part Overview

The CPH3223-TL-E is an NPN bipolar junction transistor manufactured by onsemi, rated for 50V collector-emitter breakdown voltage and 3A maximum collector current. This surface mount device in 3-CPH package configuration delivers 900mW power dissipation with 380MHz transition frequency. The part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility within the specified parameter ranges while accommodating packaging and availability constraints.

Substitute Part Grouping Explanation

Substitution of the CPH3223-TL-E is determined by the following critical electrical parameters: NPN transistor type, maximum collector-emitter breakdown voltage of 50V or higher, maximum collector current capacity of 3A or higher, and maximum power dissipation of 900mW or higher. The transition frequency of 380MHz establishes the minimum switching speed requirement. DC current gain (hFE) minimum of 200 at specified test conditions and saturation voltage characteristics must be maintained within acceptable ranges for circuit operation.

Substitute parts are grouped into two categories based on current-handling capability:

Category A (Full Current Replacement): Parts rated for 3A or greater collector current at 50V or higher breakdown voltage. These provide direct functional equivalence for applications requiring maximum current capacity.

Category B (Reduced Current Replacement): Parts rated for 1A to 2.5A collector current at 50V or higher breakdown voltage. These are suitable for applications where circuit design accommodates lower maximum current ratings while maintaining voltage and power specifications.

All substitute candidates maintain NPN configuration, surface mount technology, RoHS3 compliance, and operating temperature rating of 150°C or higher.

Engineering Selection Recommendations

CPH3216-TL-E (onsemi): Active product status with identical voltage rating (50V) and current gain specification (200 @ 100mA, 2V). Reduced maximum collector current (1A versus 3A) and higher transition frequency (420MHz versus 380MHz). Suitable for applications where circuit design accommodates 1A maximum current. Maintains onsemi manufacturer continuity and RoHS3 compliance. Packaging includes SOT-23-3 option for improved board-level compatibility.

NSS60201LT1G (onsemi): Active product with higher voltage rating (60V versus 50V) and 2A collector current capacity. Lower transition frequency (100MHz) and reduced power rating (460mW versus 900mW). Suitable for lower-frequency switching applications. Maintains onsemi manufacturer continuity and RoHS3 compliance. Operating temperature range extends to −55°C.

2SD1484KT146R (Rohm Semiconductor): Active product with 50V voltage rating and 500mA collector current. Significantly reduced power dissipation (200mW) and transition frequency (250MHz). Applicable only to low-current circuit implementations. RoHS3 compliant with extensive inventory availability.

FMMTL619TA (Diodes Incorporated): Active product with 50V voltage rating and 1.25A collector current capacity. Intermediate power rating (500mW) and transition frequency (180MHz). Maintains current gain specification (200 @ 500mA, 5V). RoHS3 compliant with extended operating temperature range (−55°C to 150°C).

Selection criteria prioritize active product status, maintained electrical specifications within application requirements, RoHS3 compliance, and inventory availability. Package compatibility with existing PCB designs requires evaluation of SOT-23-3 versus original 3-CPH package footprints.

Frequently Asked Questions (FAQ)

Q: Can CPH3216-TL-E directly replace CPH3223-TL-E in all applications?

A: CPH3216-TL-E is suitable for applications where maximum collector current does not exceed 1A. The 50V voltage rating, 900mW power dissipation, and 200 hFE specification match the original part. Applications requiring the full 3A current capacity require alternative selection or circuit redesign.

Q: What is the primary limitation of NSS60201LT1G as a substitute?

A: NSS60201LT1G provides 2A collector current and 60V voltage rating but operates at 100MHz transition frequency compared to the original 380MHz. This reduced switching speed limits applicability to lower-frequency circuit implementations. Power dissipation is also reduced to 460mW.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance status, consistent with the original CPH3223-TL-E specification.

Q: How does package type affect substitution feasibility?

A: The original CPH3223-TL-E uses SC-96 (3-CPH) package. Substitute parts employ SOT-23-3 (TO-236-3, SC-59) packages. PCB footprint compatibility requires verification. SOT-23-3 packages are industry-standard and widely supported in design tools, but physical board layout modifications may be necessary.

Q: Which substitute part provides the closest electrical match to CPH3223-TL-E?

A: CPH3216-TL-E from onsemi provides the closest match in voltage rating (50V), power dissipation (900mW), and current gain (200 @ 100mA, 2V). The primary difference is reduced maximum collector current (1A versus 3A) and higher transition frequency (420MHz versus 380MHz).

Q: Can 2SD1484KT146R be used in high-current applications?

A: No. 2SD1484KT146R is rated for maximum 500mA collector current and 200mW power dissipation, making it unsuitable for applications requiring the original part's 3A capacity or 900mW power handling.

Q: What is the inventory status of substitute parts?

A: CPH3216-TL-E: 4,571 units. NSS60201LT1G: 18,186 units. 2SD1484KT146R: 261,700 units. FMMTL619TA: 68,350 units. All parts are listed as new original stock.

Q: Do substitute parts maintain the same operating temperature range?

A: CPH3216-TL-E, 2SD1484KT146R, and the original CPH3223-TL-E are rated to 150°C maximum junction temperature. NSS60201LT1G and FMMTL619TA extend the lower operating limit to −55°C, providing wider temperature range capability.
