DRC3115T0L Equivalent & Substitute Parts

Part Overview

The DRC3115T0L is a pre-biased NPN bipolar transistor manufactured by Panasonic Electronic Components, designed for surface mount applications in the SOT-723 package. This component operates at a maximum collector-emitter voltage of 50 V with a maximum collector current of 100 mA and power dissipation of 100 mW. The device features integrated base and emitter resistors configured for pre-biased operation, eliminating the need for external biasing networks in many applications.

The DRC3115T0L is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Suitable substitutes must maintain electrical compatibility across critical parameters including voltage ratings, current specifications, and DC current gain characteristics.

Parameter Comparison

Engineering Selection Recommendations

DTC115TM3T5G (onsemi) is the primary substitute for the DRC3115T0L. This device matches the DC current gain specification of the original part at 160 @ 5mA, 10V, ensuring equivalent amplification characteristics. The DTC115TM3T5G is currently in active production status with 777 pieces available in inventory. The device is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The higher power rating of 260 mW compared to the original 100 mW provides additional thermal margin in applications. The saturation voltage specification differs slightly at 250mV @ 5mA, 10mA versus the original 250mV @ 500µA, 10mA, but remains within acceptable operating parameters for pre-biased transistor applications.

DTC115EM3T5G (onsemi) is an alternative substitute with active production status and 16,896 pieces available in inventory. This device features a lower DC current gain of 80 @ 5mA, 10V, which is half the original specification. The saturation voltage is specified at 250mV @ 300µA, 10mA. The DTC115EM3T5G is suitable for applications where the lower current gain is acceptable and where higher inventory availability is prioritized. This device is also ROHS3 compliant and REACH unaffected.

Both substitute parts are packaged in SOT-723 and maintain the 100 kOhms base resistor configuration of the original device. Both are rated for 50 V maximum collector-emitter breakdown voltage and 100 mA maximum collector current. The increased power dissipation rating of both substitutes provides design flexibility for thermal management.

Frequently Asked Questions (FAQ)

Q: Can the DTC115TM3T5G directly replace the DRC3115T0L in existing designs?

A: Yes. The DTC115TM3T5G maintains electrical compatibility across all critical parameters including voltage rating, current rating, DC current gain, and saturation voltage. Both devices are packaged in SOT-723 and feature identical base resistor values. The higher power rating of the substitute provides additional thermal capability.

Q: What is the difference between DTC115TM3T5G and DTC115EM3T5G?

A: The primary difference is DC current gain. The DTC115TM3T5G is specified at 160 @ 5mA, 10V, matching the original DRC3115T0L. The DTC115EM3T5G is specified at 80 @ 5mA, 10V, which is half the gain. The saturation voltage specifications also differ slightly. Selection depends on whether the application requires the higher current gain of the DTC115TM3T5G or can operate with the lower gain of the DTC115EM3T5G.

Q: Are both onsemi substitutes available in the same packaging format?

A: Both DTC115TM3T5G and DTC115EM3T5G are supplied in Tape & Reel (TR) packaging and are housed in the SOT-723 package, identical to the original DRC3115T0L. Both devices are surface mount components suitable for automated assembly processes.

Q: What is the significance of the higher power rating in the substitute parts?

A: The DTC115TM3T5G and DTC115EM3T5G are rated for 260 mW maximum power dissipation compared to the original 100 mW rating. This higher rating provides additional thermal margin and allows operation in applications with higher power requirements without exceeding device limits.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DTC115TM3T5G and DTC115EM3T5G are ROHS3 compliant. The original DRC3115T0L is RoHS compliant. Both substitutes are also REACH unaffected, meeting current environmental regulations.

Q: What is the moisture sensitivity level of the substitute parts?

A: Both substitute parts are rated MSL 1 (Unlimited), identical to the original DRC3115T0L. This rating indicates unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: How does the saturation voltage differ between the original and substitute parts?

A: The DRC3115T0L is specified at 250mV @ 500µA, 10mA. The DTC115TM3T5G is specified at 250mV @ 5mA, 10mA, and the DTC115EM3T5G is specified at 250mV @ 300µA, 10mA. All three devices maintain the same maximum saturation voltage of 250mV, ensuring compatible switching performance in pre-biased transistor applications.

Q: What is the product status of each substitute part?

A: The DRC3115T0L is discontinued at DiGi Electronics. The DTC115TM3T5G is active with 777 pieces in inventory. The DTC115EM3T5G is active with 16,896 pieces in inventory. Both substitutes are in current production and readily available.
