TIP117-BP Equivalent & Substitute Parts Reference

Part Overview

TIP117-BP is a PNP Darlington bipolar junction transistor (BJT) in the TO-220AB package, specified for 100 V collector-emitter breakdown voltage, 2 A collector current, and a minimum DC current gain of 1000. The part is classified as obsolete, making it necessary to identify compatible substitutes for continued production, system maintenance, or design continuity. Finding alternative models ensures ongoing availability and compliance with sourcing requirements.

Substitute Part Grouping Explanation

Substitution for TIP117-BP strictly considers the following parameters: transistor type (PNP and Darlington configuration), maximum collector-emitter breakdown voltage (100 V), maximum collector current (minimum 2 A), minimum DC current gain, power dissipation, package (TO-220-3/TO-220AB), mounting type (through hole), RoHS environmental compliance, and moisture sensitivity level. All listed substitute parts meet or exceed the specified requirements for each of these parameters.

Engineering Selection Recommendations

Due to the product status being marked as "Obsolete" for TIP117-BP, substitute components such as TIP127L-BP, which maintain "Active" product status and equivalent or higher RoHS and moisture sensitivity compliance, should be considered. Only parts that align with the environmental and handling certifications provided are shown.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when selecting a substitute for TIP117-BP?
A1: The critical parameters are transistor type (PNP - Darlington or PNP), maximum collector-emitter voltage, maximum collector current, minimum DC current gain, power dissipation, package type, mounting method, and compliance with RoHS and MSL requirements.

Q2: Can TIP127L-BP be used directly in place of TIP117-BP in the same board footprint?
A2: Both TIP117-BP and TIP127L-BP use the TO-220-3/TO-220AB package and through hole mounting type. Thus, no layout changes are required for substitution based on mechanical dimensions.

Q3: How does product status affect selection?
A3: "Obsolete" status indicates no ongoing production, leading to discontinuity in supply. Substitute parts with "Active" status support sustained availability for manufacturing and repairs.

Q4: Are there environmental compliance considerations in substitution?
A4: Both parts are ROHS3 compliant and possess a Moisture Sensitivity Level of 1 (Unlimited), meeting the required environmental and handling standards for most applications.
