Equivalent & Substitute Parts for TIP41A-S

Part Overview

The TIP41A-S is a bipolar NPN transistor from Bourns Inc., categorized under Transistors, Bipolar (BJT). It features a collector-emitter breakdown voltage of 60 V, a maximum collector current of 6 A, and is provided in a TO-220 through-hole package. The device is currently classified as "Obsolete," which necessitates the identification and selection of suitable alternative or equivalent models for continued design support, repair, or manufacturing continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for the TIP41A-S are determined strictly by matching or exceeding the key parameters: transistor type, collector current (Ic), collector-emitter breakdown voltage (Vce), Vce saturation values, current gain (hFE), power handling, thermal range, mounting type, and package form. Only parts within Transistors, Bipolar (BJT), with equivalent NPN polarity, in the TO-220-3 package, intended for through-hole mounting are considered.

Parameters defining suitability for substitution:

• Transistor Type (NPN)
• Collector Current (Ic, max)
• Collector-Emitter Breakdown Voltage (Vce, max)
• Vce Saturation (at specified Ib, Ic)
• DC Current Gain (min)
• Package / Mounting type (TO-220-3, Through Hole)
• Operating Temperature Range
• RoHS and environmental compliance

Parameter Comparison

Engineering Selection Recommendations

The main TIP41A-S transistor is obsolete. The substitute TIP41AG from onsemi is listed as "Last Time Buy" and is ROHS3 compliant. Both share identical key electrical characteristics, package form, and compliance standards. The 2N6290 PBFREE from Central Semiconductor is also ROHS3 compliant and in the TO-220-3 package, with higher collector current and power handling; however, its lower collector-emitter breakdown voltage and higher saturation voltage mark a distinction to consider based solely on provided parameters.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for selecting a substitute for the TIP41A-S?
A1: Substitution is based on matching transistor type (NPN), collector-emitter breakdown voltage, collector current rating, Vce saturation, current gain, power handling, operating temperature, mounting type, package/case, and RoHS compliance.

Q2: Are all substitutes listed in a TO-220-3 package?
A2: Yes, all substitutes provided are in a TO-220-3 through-hole package, ensuring footprint compatibility.

Q3: How does RoHS compliance affect substitution decisions?
A3: All parts listed are ROHS3 compliant, aligning with environmental and regulatory requirements for most electronic designs.

Q4: Does a higher collector current or power rating automatically indicate compatibility?
A4: Only parameters explicitly specified as required for substitution are considered. Higher ratings in current or power alone do not guarantee full equivalence unless all other key parameters also align as specified.

Q5: Can substitutes with different Vce saturation or collector-emitter breakdown voltages be used?
A5: Substitutes are only considered when these electrical parameters match or are within the specified thresholds provided for the TIP41A-S. Any parameter outside these thresholds should be reviewed based strictly on the information provided.
