CPH6153-TL-E Equivalent & Substitute Parts

Part Overview

The CPH6153-TL-E is a PNP bipolar junction transistor manufactured by onsemi, rated for 20 V collector-emitter breakdown voltage and 3 A maximum collector current. This surface mount device is packaged in a 6-CPH (SOT-23-6 Thin) configuration and delivers 1.3 W maximum power dissipation with a 500 MHz 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 across voltage, current, and thermal operating ranges while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPH6153-TL-E is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: PNP (mandatory)
• Voltage - Collector Emitter Breakdown (Max): 20 V (minimum requirement)
• Current - Collector (Ic) (Max): 3 A or greater (minimum requirement)
• Mounting Type: Surface Mount (mandatory)
• Package / Case: SOT-23-6 or compatible 6-pin surface mount packages (mandatory)
• RoHS Status: ROHS3 Compliant (mandatory)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory)

Secondary Compatibility Parameters:

• Operating Temperature Range: Must support minimum 150°C junction temperature
• Power Dissipation: 1.1 W or greater
• Frequency - Transition: No minimum requirement; higher values acceptable

Substitute parts are grouped into two categories: direct equivalents (matching all critical parameters) and functional substitutes (meeting or exceeding all critical parameters with acceptable trade-offs in secondary characteristics).

Engineering Selection Recommendations

NSS20300MR6T1G (onsemi)

This part maintains identical voltage and current ratings to the CPH6153-TL-E and is manufactured by the same supplier. The NSS20300MR6T1G is classified as active product status, ensuring continued availability and supply chain stability. The primary trade-off is reduced power dissipation (545 mW versus 1.3 W) and lower transition frequency (100 MHz versus 500 MHz). This substitute is suitable for applications where the original 500 MHz transition frequency is not a design requirement. Packaging is identical (SOT-23-6 Thin, TSOT-23-6), and all compliance certifications match the original part.

ZXT13P20DE6TA (Diodes Incorporated)

This part exceeds the collector current rating of the original (4 A versus 3 A) while maintaining the 20 V voltage specification. The ZXT13P20DE6TA is active product status with extensive inventory availability. The transition frequency is lower (90 MHz versus 500 MHz), and power dissipation is reduced (1.1 W versus 1.3 W). This substitute provides enhanced current handling capability and is suitable for applications requiring higher current margins. Package compatibility is confirmed (SOT-23-6).

ZXTP2006E6TA (Diodes Incorporated)

This part provides 3.5 A collector current rating, exceeding the original 3 A specification, while maintaining 20 V voltage rating. The ZXTP2006E6TA is active product status with moderate inventory levels. Transition frequency is lower (110 MHz versus 500 MHz), and power dissipation is reduced (1.1 W versus 1.3 W). This substitute offers improved current capacity with compatible packaging (SOT-23-6).

ZXT10P20DE6TA (Diodes Incorporated)

This part is rated for 2.5 A collector current, which is below the original 3 A specification. The ZXT10P20DE6TA is active product status with high inventory availability and includes automotive qualification (AEC-Q101). The transition frequency is 180 MHz, and power dissipation is 1.1 W. This substitute is suitable only for applications where the 2.5 A current rating is sufficient. The automotive qualification provides additional assurance for mission-critical applications.

Frequently Asked Questions (FAQ)

Q: Can NSS20300MR6T1G replace CPH6153-TL-E in all applications?

A: NSS20300MR6T1G meets the voltage and current requirements of CPH6153-TL-E. However, the transition frequency is reduced from 500 MHz to 100 MHz. Applications requiring high-frequency switching performance above 100 MHz must evaluate circuit performance with the lower frequency specification.

Q: What is the primary difference between ZXT13P20DE6TA and ZXTP2006E6TA?

A: Both parts are manufactured by Diodes Incorporated and rated for 20 V operation. ZXT13P20DE6TA provides 4 A collector current with 90 MHz transition frequency. ZXTP2006E6TA provides 3.5 A collector current with 110 MHz transition frequency. Selection depends on specific current and frequency requirements of the application.

Q: Is ZXT10P20DE6TA suitable as a direct replacement?

A: ZXT10P20DE6TA is rated for 2.5 A maximum collector current, which is below the original 3 A specification. This part is suitable only for applications where the design current requirement does not exceed 2.5 A. The automotive qualification (AEC-Q101) of this part provides additional reliability assurance for qualified applications.

Q: Are all substitute parts compatible with the original PCB layout?

A: All substitute parts use SOT-23-6 surface mount packaging, which is mechanically compatible with the original CPH6153-TL-E PCB footprint. Pin configurations are identical across all listed substitutes.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). These certifications match the original CPH6153-TL-E specifications.

Q: Why is the CPH6153-TL-E classified as obsolete?

A: The CPH6153-TL-E is listed as obsolete product status. Active substitute parts with equivalent or superior electrical specifications are available from multiple manufacturers, ensuring design continuity and supply chain reliability for new and ongoing production.

Q: Can I use a substitute part with higher power dissipation rating?

A: Yes. Substitute parts with equal or higher power dissipation ratings are acceptable. Higher power ratings provide additional thermal margin and do not negatively impact circuit performance. However, lower power ratings (such as NSS20300MR6T1G at 545 mW) require verification that the application thermal environment does not exceed the part's dissipation limit.

Q: What is the significance of transition frequency differences?

A: Transition frequency (fT) determines the maximum useful operating frequency of the transistor. The original CPH6153-TL-E operates at 500 MHz. Substitute parts with lower transition frequencies (90–180 MHz) are suitable for applications operating below their specified frequency. Applications requiring operation above the substitute part's transition frequency must be re-evaluated for performance impact.
