BD244C-S Equivalent & Substitute Parts Reference

Part Overview

The BD244C-S is a PNP bipolar junction transistor (BJT) with a collector-emitter breakdown voltage of 100 V, collector current capability of 6 A, and a through-hole TO-220 package. This component, classified under Transistors, Bipolar (BJT), is designated by Bourns Inc. as Obsolete. Due to its obsolete status and potential supply chain limitations, it is necessary to identify suitable equivalent or substitute BJT transistors that closely match its specified key electrical and mechanical parameters.

Substitute Part Grouping Explanation

All substitute and equivalent transistors are selected strictly based on the following input parameters: Transistor Type (PNP), Collector Current (Ic), Collector-Emitter Breakdown Voltage (Vce), Vce Saturation Voltage, DC Current Gain (hFE), Power Dissipation, mounting type (Through Hole), package type (TO-220-3 or equivalent), and RoHS compliance where specified. Substitute relationships are valid only if these parameters match or exceed those of BD244C-S as provided.

Engineering Selection Recommendations

For the BD244C-S, which is classified as obsolete, selection of replacement transistors should be based on matching key parameters and ensuring product compliance where required. Preference should be given to active status parts with ROHS3 compliance for environmentally regulated applications. Non-compliant or obsolete alternatives are only appropriate when compliance is not a requirement.

Frequently Asked Questions (FAQ)

Q1: What key parameters determine a valid substitute for BD244C-S?
A1: Required parameters are PNP transistor type, maximum collector current (Ic), collector-emitter breakdown voltage (Vce), Vce saturation voltage, minimum DC current gain (hFE), power dissipation, through-hole mounting, TO-220-3 or equivalent package, and RoHS compliance status.

Q2: Are all TO-220-3 PNP BJTs interchangeable as substitutes?
A2: Only devices matching or exceeding the specified electrical parameters (Ic, Vce, hFE, power) and sharing the same mounting and package are valid substitutes.

Q3: What role does RoHS compliance play in selection?
A3: RoHS compliance is required for applications subject to environmental regulation; only ROHS3 compliant transistors should be selected for these cases.

Q4: Can higher-rated transistors be used as substitutes?
A4: Substitutes with higher ratings for current, voltage, or power are valid, provided all other key parameters match.

Q5: How does the obsolete status impact replacement?
A5: Obsolete status indicates that sourcing BD244C-S may become difficult; alternatives with active production status are recommended for continued availability.

Q6: Is package variation within TO-220 series significant?
A6: Variations within the TO-220-3 or equivalent packages are acceptable as long as the physical and footprint compatibility is maintained according to specified parameters.
