TIP41AG Equivalent & Substitute Parts

Part Overview

The TIP41AG is an NPN Bipolar Junction Transistor (BJT) manufactured by onsemi, designed for general-purpose switching and amplification applications. This device features a maximum collector current of 6 A, collector-emitter breakdown voltage of 60 V, and maximum power dissipation of 2 W in a Through Hole TO-220-3 package. The TIP41AG is currently in Last Time Buy status, indicating that new production has ceased and existing inventory is being depleted. Identification of equivalent substitute parts is necessary to ensure continued component availability for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP41AG is determined by electrical and mechanical compatibility within the NPN BJT category. The primary substitution criterion is the ability to operate within the same or higher voltage and current ratings while maintaining identical or superior DC current gain characteristics and thermal performance specifications.

The TIP41CG qualifies as a direct substitute based on the following key parameters:

• Transistor Type: Both devices are NPN configuration
• Maximum Collector Current (Ic): Both rated at 6 A
• Vce Saturation: Identical at 1.5V @ 600mA, 6A
• Collector Cutoff Current: Both at 700µA maximum
• DC Current Gain (hFE): Both minimum 15 @ 3A, 4V
• Power Dissipation: Both rated at 2 W maximum
• Transition Frequency: Both at 3 MHz
• Operating Temperature Range: Both -65°C to 150°C (TJ)
• Package / Case: Both TO-220-3 Through Hole
• RoHS Compliance: Both ROHS3 Compliant

The TIP41CG provides enhanced voltage capability at 100 V maximum collector-emitter breakdown voltage compared to the TIP41AG at 60 V, making it suitable for applications requiring higher voltage headroom while maintaining full backward compatibility in all other electrical and mechanical parameters.

Engineering Selection Recommendations

The TIP41CG is the recommended substitute for the TIP41AG based on product lifecycle and regulatory compliance considerations.

Product Status Rationale: The TIP41AG is designated Last Time Buy, indicating cessation of production and depletion of available inventory. The TIP41CG maintains Active product status with significantly higher inventory availability (25,100 pieces in stock versus 2,345 pieces for the TIP41AG), ensuring long-term component supply continuity.

Compliance and Certification: Both devices maintain identical RoHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in applications subject to environmental and hazardous substance restrictions. Both devices carry the same ECCN (EAR99) and HTSUS (8541.29.0095) classifications.

Electrical Compatibility: The TIP41CG provides superior voltage rating (100 V versus 60 V) while maintaining identical current, gain, saturation, and thermal characteristics. This enhanced voltage capability provides additional design margin without introducing any electrical incompatibility or performance degradation in existing circuit implementations.

Mechanical Compatibility: Both devices utilize identical TO-220-3 Through Hole packaging, ensuring direct mechanical and thermal interface compatibility with existing printed circuit board layouts and thermal management solutions.

Frequently Asked Questions (FAQ)

Q: Can the TIP41CG be used as a direct replacement for the TIP41AG in existing designs?

A: Yes. The TIP41CG is electrically and mechanically compatible with the TIP41AG. All critical electrical parameters including maximum collector current (6 A), saturation voltage (1.5V @ 600mA, 6A), DC current gain (15 @ 3A, 4V), power dissipation (2 W), and operating temperature range (-65°C to 150°C) are identical. The TO-220-3 package footprint is unchanged, requiring no circuit board modifications.

Q: What is the primary difference between the TIP41AG and TIP41CG?

A: The TIP41CG features a maximum collector-emitter breakdown voltage of 100 V compared to 60 V for the TIP41AG. This higher voltage rating provides increased design margin for applications operating near the voltage limits of the TIP41AG, while all other electrical and mechanical specifications remain identical.

Q: Are there any thermal management differences between these devices?

A: No. Both devices are rated for identical maximum power dissipation (2 W) and operating temperature range (-65°C to 150°C junction temperature). Thermal management requirements and heat sink considerations remain unchanged when substituting the TIP41CG for the TIP41AG.

Q: Do both devices meet the same regulatory and compliance standards?

A: Yes. Both the TIP41AG and TIP41CG are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications. No compliance or regulatory differences exist between these devices.

Q: Why is the TIP41CG recommended over the TIP41AG?

A: The TIP41AG is in Last Time Buy status with limited remaining inventory (2,345 pieces). The TIP41CG is in Active production status with substantially higher inventory availability (25,100 pieces), ensuring reliable long-term component supply for production and design requirements.

Q: Are there any circuit design considerations when switching from TIP41AG to TIP41CG?

A: No design modifications are required. The TIP41CG operates identically to the TIP41AG in all circuit configurations. The enhanced voltage rating of the TIP41CG provides additional safety margin without requiring any changes to base drive circuits, collector load resistances, or thermal management implementations.
