Equivalent & Substitute Parts for 2SC3265-Y,LF

Part Overview

The 2SC3265-Y,LF is an NPN bipolar junction transistor manufactured by Toshiba Semiconductor and Storage. This surface mount device operates at a maximum collector voltage of 25 V with a collector current rating of 800 mA and maximum power dissipation of 200 mW. The transistor features a transition frequency of 120 MHz and is housed in a TO-236-3 (SOT-23-3) package. The device is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements permit operation within specified electrical and mechanical parameter ranges, or when identical electrical performance is available from alternative manufacturers in compatible packaging.

Substitute Part Grouping Explanation

Substitute parts for the 2SC3265-Y,LF are classified into two categories based on electrical parameter alignment:

Parametric Equivalent: Parts that match all critical electrical specifications including collector current rating (800 mA), collector-emitter breakdown voltage (25 V), power dissipation (200 mW), transition frequency (120 MHz), and DC current gain (160 @ 100mA, 1V). These parts operate identically within the specified parameter envelope.

Functional Equivalent: Parts that operate within the same voltage and package class but with different current ratings or frequency characteristics. These substitutes are suitable when circuit design permits operation at alternative current or frequency specifications while maintaining the 25 V collector-emitter breakdown voltage and SOT-23-3 package compatibility.

The following parameters determine substitution eligibility:

• Transistor Type: NPN (required)
• Voltage - Collector Emitter Breakdown (Max): 25 V (required)
• Package / Case: TO-236-3, SC-59, SOT-23-3 (required)
• Mounting Type: Surface Mount (required)
• RoHS Status: ROHS3 Compliant (required)

Parameter Comparison

Engineering Selection Recommendations

KSC3265YMTF (onsemi) is a parametric equivalent to the 2SC3265-Y,LF. This part maintains identical electrical specifications across all critical parameters: 800 mA collector current, 25 V collector-emitter breakdown voltage, 200 mW power dissipation, 120 MHz transition frequency, and 160 DC current gain at 100 mA. Both devices are ROHS3 compliant, active production status, and housed in compatible SOT-23-3 packaging. This substitute provides direct functional replacement with no circuit design modifications required.

BC818-40LT1G (onsemi) operates within the same voltage class (25 V) and package format but with reduced maximum collector current (500 mA versus 800 mA) and lower transition frequency (100 MHz versus 120 MHz). This substitute is suitable for applications where circuit current requirements do not exceed 500 mA and frequency performance at 100 MHz is acceptable. The device is ROHS3 compliant and in active production.

FSB649 (onsemi) operates within the same voltage class (25 V) and package format but with significantly higher maximum collector current (3 A) and higher transition frequency (150 MHz). This substitute is suitable for applications requiring higher current capacity or improved frequency performance. The device is ROHS3 compliant and in active production.

All substitute parts maintain surface mount SOT-23-3 packaging compatibility and ROHS3 compliance status with the original 2SC3265-Y,LF device.

Frequently Asked Questions (FAQ)

Q: Can KSC3265YMTF directly replace 2SC3265-Y,LF without circuit modifications?

A: Yes. The KSC3265YMTF maintains identical electrical specifications including 800 mA collector current, 25 V breakdown voltage, 200 mW power dissipation, 120 MHz transition frequency, and 160 DC current gain. Both devices use SOT-23-3 packaging and are ROHS3 compliant. No circuit design changes are required.

Q: When is BC818-40LT1G an appropriate substitute?

A: BC818-40LT1G is appropriate when circuit design permits operation at reduced collector current (500 mA maximum) and lower transition frequency (100 MHz). The 25 V collector-emitter breakdown voltage and SOT-23-3 package remain compatible. Applications requiring the full 800 mA current rating of the original device cannot use this substitute.

Q: When is FSB649 an appropriate substitute?

A: FSB649 is appropriate when circuit design requires higher collector current capacity (3 A maximum) or improved frequency performance (150 MHz transition frequency). The 25 V collector-emitter breakdown voltage and SOT-23-3 package remain compatible. Applications with current requirements below 800 mA can use this higher-rated device.

Q: Are all substitute parts in the same package?

A: Yes. The 2SC3265-Y,LF and all listed substitutes (KSC3265YMTF, BC818-40LT1G, FSB649) use the TO-236-3 (SOT-23-3) surface mount package. Pin configuration and PCB footprint compatibility are maintained across all parts.

Q: What compliance certifications apply to these substitutes?

A: All parts listed—2SC3265-Y,LF, KSC3265YMTF, BC818-40LT1G, and FSB649—are ROHS3 compliant. All devices carry MSL 1 (unlimited) moisture sensitivity level rating. All parts are in active production status.

Q: What is the key difference between the substitute parts?

A: The primary differences are collector current rating and transition frequency. KSC3265YMTF matches the original exactly. BC818-40LT1G has lower current (500 mA) and frequency (100 MHz). FSB649 has higher current (3 A) and frequency (150 MHz). All maintain the 25 V voltage rating and SOT-23-3 package.
