Equivalent & Substitute Parts Reference: 2SC4495 Bipolar (BJT) Transistor

Part Overview

The Sanken Electric USA Inc. 2SC4495 is an NPN Bipolar Junction Transistor (BJT) rated for 50 V, 3 A, with a maximum power dissipation of 25 W. It features a TO-220-3 Full Pack (TO-220F) package for through-hole mounting and operates at a transition frequency of 40 MHz. With a minimum DC current gain (hFE) of 500 at specified conditions, the 2SC4495 fulfills general switching and amplification functions. This product is marked as obsolete, necessitating the identification of substitute parts for ongoing or new designs maintaining equivalent electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for Bipolar (BJT) transistors in this category are grouped strictly based on the following parameters: transistor type, maximum collector current, maximum collector-emitter voltage, Vce saturation characteristics, collector cutoff current, minimum DC current gain at stated conditions, maximum power dissipation, transition frequency, operating temperature, mounting type, package/case, supplier device package, RoHS status, and MSL. Substitution is restricted to parts matching these criteria as cited.

Parameter Comparison

Engineering Selection Recommendations

The main part 2SC4495 is listed as obsolete and has RoHS compliance and MSL 1 (Unlimited). The substitute part 2SC3852 is active and maintains equivalent compliance with ROHS3 and MSL 1 (Unlimited). Both parts are supplied in TO-220F, through-hole mounting, and meet identical collector current, minimum DC current gain, power dissipation, and cutoff current specifications. Electrical and mechanical compatibility are ensured based on provided values.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match for a BJT transistor substitution in this category?
A1: Substitution requires matching transistor type, collector current (Ic max), collector-emitter voltage (Vce max), DC current gain, Vce saturation, cutoff current, power rating, and frequency—per provided specifications.

Q2: How is package compatibility determined for these substitute BJTs?
A2: Compatibility is based strictly on package/case (TO-220-3 Full Pack) and supplier device package (TO-220F), ensuring identical mechanical fit for through-hole mounting.

Q3: Are compliance and certification parameters relevant during substitution?
A3: Yes. RoHS status and Moisture Sensitivity Level (MSL) are required to match specified standards; both main and substitute parts meet these criteria.

Q4: Is operating temperature range relevant in selecting substitutes?
A4: Both the main and substitute parts specify an operating junction temperature of 150°C, maintaining thermal characteristics per input.

Q5: What is the status implication for component selection?
A5: The 2SC4495 is obsolete. The active status of 2SC3852 supports sustained availability and compliance for replacement needs per allowed parameters.
