BD250C-S Equivalent & Substitute Parts Reference

Part Overview

BD250C-S is a PNP power bipolar junction transistor from Bourns Inc., rated for 100 V and a collector current of 25 A, housed in a SOT-93 (TO-218-3) through-hole package. The device is currently classified as obsolete; therefore, identifying substitute or equivalent parts with matching or superior key parameters is essential to maintain circuit functionality and ensure continuous manufacturing or repair processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution for transistors in this category is permitted when the following key parameters are equivalent: transistor type (PNP), maximum collector current (Ic), maximum collector-emitter voltage (Vce), Vce saturation voltage at the specified Ib and Ic, maximum collector cutoff current, minimum DC current gain at specified test points, power dissipation capability, through-hole mounting, package style, and RoHS compliance status. Only parameters explicitly provided are used for determining suitability.

Parameter Comparison

Engineering Selection Recommendations

Based on the product status, BD250C-S is obsolete with available stock noted. Substitute parts such as TIP36CG are active, RoHS3 compliant, and matched strictly on provided electrical and mechanical parameters. Selection among available devices should consider obsolete status and RoHS3 compliance when maintaining or updating design sources.

Frequently Asked Questions (FAQ)

Q1: What criteria determine equivalency for BD250C-S substitute selection?
A1: Substitute parts must match the following explicit parameters: transistor type (PNP), maximum collector current (25 A), maximum Vce (100 V), Vce saturation @ Ib and Ic, maximum collector cutoff current, minimum DC current gain (hFE) at specified test conditions, power dissipation, mounting type (through hole), package, and RoHS3 status.

Q2: Are there differences in package style between BD250C-S and TIP36CG?
A2: Yes. BD250C-S uses TO-218-3, also referred to as SOT-93, while TIP36CG uses TO-247-3. Both are through-hole packages; the difference should be considered if mechanical fit or board footprint is critical.

Q3: Can the TIP36CG be used to directly replace BD250C-S?
A3: If all required electrical and mechanical parameters listed are met in the application, and the package compatibility is suitable for the intended assembly, direct substitution is allowable using only the parameters provided.

Q4: Is RoHS compliance maintained with the substitute TIP36CG?
A4: Yes. Both BD250C-S and TIP36CG are listed as ROHS3 compliant.

Q5: Does the difference in DC current gain (hFE) between BD250C-S and TIP36CG affect suitability?
A5: TIP36CG has a higher minimum hFE at its listed test condition (15 @ 15A, 4V) compared to BD250C-S (5 @ 25A, 4V). The hFE provided is acceptable within the parameters explicitly listed.

Q6: How does the product status affect engineering selection?
A6: BD250C-S is obsolete. Selection should favor active status devices such as TIP36CG to ensure long-term availability, provided all required parameters match.
