TIP41A-BP Equivalent & Substitute Parts

Part Overview

The TIP41A-BP is an NPN bipolar junction transistor manufactured by Micro Commercial Co, designed for general-purpose switching and amplification applications. This device features a 60 V collector-emitter breakdown voltage rating, 6 A maximum collector current, and 2 W power dissipation capability in a TO-220AB through-hole package. The TIP41A-BP is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP41A-BP is determined by electrical and mechanical parameter compatibility within the NPN bipolar transistor category. The critical parameters governing substitution are:

Electrical Parameters:

• Collector-emitter breakdown voltage (VCEO)
• Maximum collector current (Ic)
• Power dissipation rating (Pmax)
• DC current gain (hFE)
• Saturation voltage (Vce sat)
• Transition frequency (fT)

Mechanical Parameters:

• Package type (TO-220-3)
• Mounting configuration (Through Hole)
• Pin compatibility

Substitute parts must maintain electrical ratings equal to or greater than the TIP41A-BP across all critical parameters to ensure functional equivalence. Parts with higher voltage or current ratings are acceptable for direct substitution in applications requiring the TIP41A-BP specifications.

Engineering Selection Recommendations

TIP41C-BP (Direct Substitute - Recommended Primary Choice)

The TIP41C-BP is the preferred direct substitute for the obsolete TIP41A-BP. This part is manufactured by the same supplier (Micro Commercial Co) and maintains identical electrical specifications for collector current, power dissipation, transition frequency, and DC current gain. The TIP41C-BP features an enhanced collector-emitter breakdown voltage rating of 100 V compared to the 60 V rating of the TIP41A-BP, providing superior voltage margin in applications operating near the maximum voltage specification. The TIP41C-BP holds Active product status with substantial inventory availability (14,950 pieces), ensuring long-term procurement viability. Both parts are ROHS3 compliant and share identical package configurations (TO-220-3), enabling direct pin-compatible substitution without circuit modification.

TIP41AG (Parametric Equivalent - Secondary Option)

The TIP41AG, manufactured by onsemi, provides parametric equivalence to the TIP41A-BP with identical electrical performance across all critical specifications: 60 V breakdown voltage, 6 A collector current, 2 W power rating, 3 MHz transition frequency, and matching DC current gain characteristics. The TIP41AG offers an extended operating temperature range (-65°C to 150°C) compared to the TIP41A-BP (150°C maximum), providing enhanced thermal performance in low-temperature environments. The TIP41AG is classified as Last Time Buy, indicating limited future availability. This part is suitable for applications requiring parametric equivalence to the original TIP41A-BP specification. ROHS3 compliance and TO-220-3 package configuration ensure mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TIP41C-BP directly replace the TIP41A-BP in existing designs?

A: Yes. The TIP41C-BP is a direct pin-compatible substitute with identical electrical performance in all critical parameters. The enhanced 100 V breakdown voltage rating of the TIP41C-BP provides additional voltage margin and does not create compatibility issues in applications designed for the 60 V TIP41A-BP.

Q: What is the primary difference between the TIP41C-BP and TIP41AG?

A: The TIP41C-BP and TIP41AG are both parametrically equivalent to the TIP41A-BP but originate from different manufacturers. The TIP41C-BP is manufactured by Micro Commercial Co (same as the original part) and maintains Active product status with high inventory levels. The TIP41AG is manufactured by onsemi and is classified as Last Time Buy. Both parts share identical electrical specifications and TO-220-3 package configuration.

Q: Are there any package or pinout differences between these substitute parts?

A: No. All three parts (TIP41A-BP, TIP41C-BP, and TIP41AG) utilize the TO-220-3 package with identical through-hole mounting configuration and pin assignments. Direct substitution requires no circuit board modifications.

Q: Which substitute part should be selected for new designs?

A: The TIP41C-BP is the recommended choice for new designs. This part is manufactured by the original supplier, maintains Active product status, and offers superior voltage rating (100 V) with substantial inventory availability. The TIP41AG is suitable as a secondary option when TIP41C-BP availability is constrained.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TIP41A-BP, TIP41C-BP, and TIP41AG are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the inventory status of each substitute part?

A: The TIP41C-BP has the highest inventory availability with 14,950 pieces in stock. The TIP41AG has 2,345 pieces available but is classified as Last Time Buy, indicating declining future availability. The original TIP41A-BP has 900 pieces in stock but is obsolete.
