Substitute Part Grouping Explanation

Substitution of the TIP41B-BP is determined by electrical and mechanical parameter compatibility within the NPN BJT transistor category. The primary substitution criteria are:

Electrical Compatibility Requirements:

• Transistor Type: NPN (must match)
• Maximum Collector Current (Ic): Equal to or greater than 6 A
• Collector-Emitter Breakdown Voltage (Vce): Equal to or greater than 80 V
• Power Dissipation: Equal to or greater than 2 W
• Transition Frequency: Equal to or greater than 3 MHz
• Operating Temperature Range: Equal to or greater than 150°C (TJ)

Mechanical Compatibility Requirements:

• Package / Case: TO-220-3 (must match)
• Mounting Type: Through Hole (must match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (must match)

The TIP41C-BP meets all substitution criteria and is classified as an Active product, providing enhanced availability and long-term support compared to the Obsolete TIP41B-BP.

Parameter Comparison

Engineering Selection Recommendations

The TIP41C-BP is the direct substitute for the TIP41B-BP. Both transistors share identical electrical performance specifications for collector current, power dissipation, transition frequency, and operating temperature. The TIP41C-BP provides a higher collector-emitter breakdown voltage rating of 100 V compared to the 80 V rating of the TIP41B-BP, offering enhanced voltage margin in applications operating near the maximum voltage specification.

The TIP41C-BP is classified as Active product status, ensuring continued availability, manufacturing support, and compliance with current regulatory standards. The TIP41B-BP is Obsolete, presenting procurement risk and potential discontinuation of supply. Both parts maintain ROHS3 compliance and identical TO-220-3 package specifications, ensuring mechanical and thermal compatibility in existing PCB designs.

Selection of the TIP41C-BP eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the TIP41B-BP.

Frequently Asked Questions (FAQ)

Q: Can the TIP41C-BP directly replace the TIP41B-BP in existing designs?

A: Yes. The TIP41C-BP is electrically and mechanically compatible with the TIP41B-BP. Both transistors feature identical maximum collector current (6 A), power dissipation (2 W), transition frequency (3 MHz), and operating temperature (150°C TJ). Both use the TO-220-3 package with Through Hole mounting. The TIP41C-BP provides a higher breakdown voltage rating (100 V vs. 80 V), which is a performance enhancement that does not affect compatibility.

Q: What is the primary difference between the TIP41B-BP and TIP41C-BP?

A: The primary difference is the collector-emitter breakdown voltage rating. The TIP41B-BP is rated for 80 V maximum, while the TIP41C-BP is rated for 100 V maximum. The TIP41C-BP also has Active product status, ensuring ongoing availability and support, whereas the TIP41B-BP is Obsolete.

Q: Are there any package or mounting differences between these transistors?

A: No. Both the TIP41B-BP and TIP41C-BP use the TO-220-3 package with Through Hole mounting. They are mechanically and thermally identical, requiring no PCB layout modifications for substitution.

Q: Does the TIP41C-BP meet the same compliance standards as the TIP41B-BP?

A: Yes. Both transistors are ROHS3 compliant and carry identical regulatory certifications (ECCN: EAR99, HTSUS: 8541.29.0095). The TIP41C-BP additionally carries REACH Unaffected status.

Q: Why should I select the TIP41C-BP over the TIP41B-BP?

A: The TIP41C-BP should be selected because the TIP41B-BP is Obsolete. Selecting an Active product ensures long-term availability, manufacturing continuity, and reduced procurement risk. The TIP41C-BP provides identical electrical performance with enhanced voltage rating, making it the preferred choice for new designs and ongoing production support.
