Key Parameters

Substitute Part Grouping Explanation

Substitution of the DCP68-25-13 is determined by the following critical parameters:

Primary Substitution Criteria:

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): 20 V minimum
• Current - Collector (Ic) (Max): 1 A minimum
• Mounting Type: Surface Mount
• Package / Case: SOT-223-3 compatible (TO-261-4, TO-261AA)

Secondary Compatibility Factors:

• Operating Temperature Range: -55°C ~ 150°C or wider
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

The substitute parts listed maintain electrical compatibility within the specified voltage and current ratings. Variations in transition frequency, power dissipation, and DC current gain (hFE) are acceptable provided the minimum specifications are met or exceeded for the intended application circuit.

Parameter Comparison

Engineering Selection Recommendations

DCP68-13 (Diodes Incorporated)

The DCP68-13 is the primary recommended substitute. It maintains identical electrical specifications for voltage, current, and saturation characteristics. Both parts share the same base product number (DCP68) and are manufactured by Diodes Incorporated. The DCP68-13 is Active status, ensuring long-term availability. This part is suitable for direct replacement in existing designs.

BCP68T1G (onsemi)

The BCP68T1G is an Active alternative from onsemi with identical voltage and current ratings. It provides higher power dissipation (1.5 W versus 1 W) and an extended operating temperature range (-65°C ~ 150°C). The transition frequency is lower (60 MHz versus 330 MHz), which may impact high-frequency applications. This part is available in high inventory quantities and is ROHS3 compliant.

BCP68,115 (NXP USA Inc.)

The BCP68,115 is an Active alternative from NXP USA Inc. with identical voltage and current ratings. It provides higher power dissipation (1.4 W versus 1 W) and meets all compliance requirements. The transition frequency is lower (170 MHz versus 330 MHz). This part is suitable for applications where lower frequency operation is acceptable.

BCP68-25,115 (Nexperia USA Inc.)

The BCP68-25,115 is an Active alternative with higher current rating (2 A versus 1 A) and lower power dissipation (650 mW versus 1 W). This part is suitable for applications requiring higher current capacity. The transition frequency is lower (170 MHz versus 330 MHz). The higher current rating provides design margin for current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can DCP68-13 be used as a direct replacement for DCP68-25-13?

A: Yes. The DCP68-13 maintains identical electrical specifications for voltage (20 V), current (1 A), saturation voltage, and power dissipation (1 W). Both parts use the SOT-223-3 package and are manufactured by Diodes Incorporated. The DCP68-13 is Active status, ensuring continued availability.

Q: What is the difference between DCP68-25-13 and BCP68-25,115?

A: The BCP68-25,115 has a higher maximum collector current (2 A versus 1 A) and lower power dissipation (650 mW versus 1 W). Both maintain the 20 V voltage rating. The BCP68-25,115 is manufactured by Nexperia USA Inc. and is Active status. The lower transition frequency (170 MHz versus 330 MHz) may affect high-frequency circuit performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (DCP68-13, BCP68,115, BCP68-25,115, and BCP68T1G) are ROHS3 compliant and have MSL Rating 1 (Unlimited), matching the original DCP68-25-13 specifications.

Q: Which substitute part has the widest operating temperature range?

A: The BCP68T1G from onsemi has an operating temperature range of -65°C ~ 150°C, which is wider than the DCP68-25-13 range of -55°C ~ 150°C. The other substitutes (DCP68-13, BCP68,115, BCP68-25,115) have operating temperature ranges of -55°C ~ 150°C or 150°C maximum.

Q: Can BCP68T1G be used in high-frequency applications?

A: The BCP68T1G has a transition frequency of 60 MHz, which is significantly lower than the DCP68-25-13 (330 MHz). For applications requiring frequencies above 60 MHz, the DCP68-13 or BCP68,115 are more suitable alternatives.

Q: What is the difference in power dissipation between the substitute parts?

A: Power dissipation ratings vary: DCP68-13 (1 W), BCP68,115 (1.4 W), BCP68-25,115 (650 mW), and BCP68T1G (1.5 W). The BCP68T1G provides the highest power dissipation capability. The BCP68-25,115 has the lowest rating but is rated for higher collector current (2 A).

Q: Are all substitute parts available in SOT-223 packaging?

A: Yes. All substitute parts use SOT-223 packaging (TO-261-4, TO-261AA variants), which is mechanically compatible with the original DCP68-25-13 SOT-223-3 package for PCB mounting.

Q: Which substitute part has the highest DC current gain (hFE)?

A: The DCP68-25-13 and BCP68-25,115 both have a minimum DC current gain of 160 @ 500mA, 1V. The DCP68-13, BCP68,115, and BCP68T1G have a minimum DC current gain of 85 @ 500mA, 1V.
