Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD1815T-TL-H is determined by electrical and mechanical parameter compatibility within the NPN bipolar transistor category. The critical parameters governing substitution are:

Electrical Parameters:

• Voltage - Collector Emitter Breakdown (Max): 100 V minimum
• Current - Collector (Ic) (Max): 3 A minimum
• Power - Max: 1 W minimum
• Frequency - Transition: 180 MHz minimum
• DC Current Gain (hFE): 200 minimum @ 500mA, 5V
• Vce Saturation: 400mV maximum @ 150mA, 1.5A

Mechanical Parameters:

• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must meet or exceed all specified electrical parameters and maintain identical mechanical compatibility. Parts that exceed the maximum collector current rating (4 A) remain compatible for applications requiring 3 A operation, provided all other parameters are satisfied.

Engineering Selection Recommendations

2SD1815T-TL-E: This part is electrically equivalent to the 2SD1815T-TL-H with identical maximum collector current (3 A), voltage rating (100 V), and power dissipation (1 W). However, the DC current gain specification differs (70 @ 500mA, 5V versus 200 @ 500mA, 5V). This part is classified as obsolete. Selection of this substitute requires verification that the lower DC current gain does not impact circuit performance in the target application.

2SD1816T-TL-E: This part provides higher maximum collector current (4 A) compared to the 2SD1815T-TL-H (3 A), while maintaining the same voltage rating (100 V) and power dissipation (1 W). The DC current gain matches the main part specification (200 @ 500mA, 5V). Vce saturation parameters are specified at higher current levels (200mA, 2A versus 150mA, 1.5A). This part is classified as obsolete and is supplied in Cut Tape (CT) packaging.

2SD1816T-TL-H: This part provides higher maximum collector current (4 A) compared to the 2SD1815T-TL-H (3 A), while maintaining identical voltage rating (100 V), power dissipation (1 W), and DC current gain specification (200 @ 500mA, 5V). This part is classified as active and is supplied in Tape & Reel (TR) packaging, ensuring ongoing availability. The 2SD1816T-TL-H is the preferred substitute for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the 2SD1815T-TL-E be used as a direct replacement for the 2SD1815T-TL-H?

A: The 2SD1815T-TL-E shares identical electrical ratings for voltage (100 V), current (3 A), power (1 W), and frequency (180 MHz). However, the DC current gain specification is lower (70 versus 200 @ 500mA, 5V). Direct substitution is possible only if the circuit design does not depend on the higher current gain of the original part.

Q: What is the primary advantage of the 2SD1816T-TL-H over the 2SD1815T-TL-H?

A: The 2SD1816T-TL-H provides a higher maximum collector current rating (4 A versus 3 A) while maintaining all other electrical specifications. Additionally, the 2SD1816T-TL-H is classified as active, ensuring continued availability and supply chain support, whereas the 2SD1815T-TL-H is obsolete.

Q: Are all substitute parts available in the same package?

A: All substitute parts utilize the TO-252-3 DPAK (2 Leads + Tab) surface mount package. Packaging format differs: the 2SD1815T-TL-H is supplied in Tape & Reel (TR), the 2SD1815T-TL-E in standard packaging, and the 2SD1816T-TL-E in Cut Tape (CT). The 2SD1816T-TL-H is supplied in Tape & Reel (TR).

Q: What is the moisture sensitivity level for these parts?

A: All parts listed, including the main part and substitutes, have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Are these parts RoHS compliant?

A: The 2SD1815T-TL-H does not specify RoHS status in the provided data. The substitute parts 2SD1815T-TL-E, 2SD1816T-TL-E, and 2SD1816T-TL-H are all ROHS3 compliant.

Q: Can the 2SD1816T-TL-E be used in applications requiring 3 A operation?

A: Yes. The 2SD1816T-TL-E is rated for 4 A maximum collector current, which exceeds the 3 A requirement of the original 2SD1815T-TL-H. The part is suitable for applications requiring 3 A operation, provided all other electrical parameters meet circuit requirements.
