2SA1832-Y,LF Equivalent & Substitute Parts

Part Overview

The 2SA1832-Y,LF is an active PNP bipolar junction transistor manufactured by Toshiba Semiconductor and Storage. This surface mount device is rated for 50 V collector-emitter breakdown voltage with a maximum collector current of 150 mA and 100 mW power dissipation. The transistor operates at a transition frequency of 80 MHz and is housed in an SC-75 (SOT-416) package in tape and reel format. The part is ROHS3 compliant with unlimited moisture sensitivity rating. Equivalent substitute parts are identified based on matching electrical specifications and mechanical compatibility to support circuit design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SA1832-Y,LF are identified based on the following critical electrical and mechanical parameters:

Matching Criteria:

• Transistor type: PNP
• Maximum collector current: 150 mA
• Maximum collector-emitter breakdown voltage: 50 V
• Package type: SC-75 (SOT-416) surface mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The 2SA1774TLR from Rohm Semiconductor meets all substitution criteria. Both devices share identical collector current ratings, breakdown voltage specifications, and package form factors. The substitute part operates within compatible electrical parameters and maintains surface mount compatibility. Differences in power dissipation, transition frequency, and operating temperature represent enhanced performance characteristics in the substitute device and do not preclude substitution in applications designed for the 2SA1832-Y,LF.

Parameter Comparison

Engineering Selection Recommendations

Both the 2SA1832-Y,LF and 2SA1774TLR are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, confirming suitability for current manufacturing and environmental standards. The 2SA1774TLR provides enhanced performance specifications including higher power dissipation (150 mW versus 100 mW), increased transition frequency (140 MHz versus 80 MHz), and extended operating temperature range (150°C versus 125°C). These enhanced characteristics ensure the substitute part operates within or exceeds the electrical envelope of the original device. Both devices maintain identical collector current and breakdown voltage ratings, confirming direct substitution capability in circuits designed for the 2SA1832-Y,LF. Selection between these parts depends on supply availability, packaging format preference (tape and reel versus cut tape), and inventory requirements rather than electrical performance constraints.

Frequently Asked Questions (FAQ)

Q: Can the 2SA1774TLR directly replace the 2SA1832-Y,LF in existing circuit designs?

A: Yes. Both devices are PNP transistors with identical maximum collector current (150 mA) and collector-emitter breakdown voltage (50 V) ratings. The SC-75 (SOT-416) package form factor is identical, enabling direct PCB footprint compatibility. The 2SA1774TLR operates within the electrical specifications required by circuits designed for the 2SA1832-Y,LF.

Q: What are the key differences between these two parts?

A: The 2SA1774TLR offers enhanced performance in three areas: maximum power dissipation (150 mW versus 100 mW), transition frequency (140 MHz versus 80 MHz), and maximum operating temperature (150°C versus 125°C). These differences represent performance improvements that do not affect substitution compatibility.

Q: Are there packaging differences between the 2SA1832-Y,LF and 2SA1774TLR?

A: Both devices use the SC-75 (SOT-416) surface mount package. The primary packaging difference is the supplier format: the 2SA1832-Y,LF is supplied in tape and reel (TR) format, while the 2SA1774TLR is available in cut tape (CT) and Digi-Reel® format. This distinction affects handling and assembly processes but not electrical or mechanical compatibility.

Q: Do both parts meet current environmental and compliance standards?

A: Yes. Both the 2SA1832-Y,LF and 2SA1774TLR are ROHS3 compliant with moisture sensitivity level 1 (unlimited), confirming compliance with current environmental regulations and manufacturing standards.

Q: What is the DC current gain difference between these parts?

A: The 2SA1832-Y,LF specifies a minimum DC current gain (hFE) of 120 at 2 mA collector current and 6 V collector-emitter voltage. The 2SA1774TLR specifies a minimum DC current gain of 180 at 1 mA collector current and 6 V collector-emitter voltage. These measurements are taken at different operating points and reflect device characterization differences rather than substitution incompatibility.

Q: Can the 2SA1832-Y,LF substitute for the 2SA1774TLR?

A: Yes. The 2SA1832-Y,LF meets the electrical requirements of circuits designed for the 2SA1774TLR, as it shares identical collector current and breakdown voltage ratings. However, applications requiring the enhanced power dissipation, transition frequency, or operating temperature range of the 2SA1774TLR should use the substitute part to ensure performance margins.
