TIP142TU Equivalent & Substitute Parts

Part Overview

The TIP142TU is an NPN Darlington bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 10 A maximum collector current in a TO-220-3 through-hole package. This device is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support and procurement continuity. The TIP142TU delivers 80 W maximum power dissipation with a minimum DC current gain of 1000 at 5 A collector current and 4 V collector-emitter voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP142TU is determined by electrical and mechanical compatibility within the NPN Darlington transistor category. The critical parameters governing substitution are:

• Transistor Type: NPN - Darlington configuration
• Voltage Rating: Collector-emitter breakdown voltage of 100 V or greater
• Current Rating: Maximum collector current of 10 A or greater
• Power Dissipation: 80 W or greater
• Package: TO-220-3 through-hole mounting
• Operating Temperature: 150°C or greater junction temperature rating

The BDW93C meets these substitution criteria with a higher maximum collector current rating of 12 A, identical voltage and power ratings, and compatible through-hole TO-220 packaging. Both devices operate at the same maximum junction temperature of 150°C.

Parameter Comparison

Engineering Selection Recommendations

The BDW93C is a direct substitute for the TIP142TU based on electrical and mechanical parameter alignment. The BDW93C offers the following advantages for component selection:

• Active Product Status: The BDW93C is actively manufactured by STMicroelectronics, ensuring long-term availability and supply chain continuity, whereas the TIP142TU is obsolete.
• Higher Current Rating: The BDW93C supports 12 A maximum collector current compared to 10 A for the TIP142TU, providing additional design margin in current-limited applications.
• RoHS3 Compliance: The BDW93C meets ROHS3 environmental standards, supporting modern manufacturing and regulatory requirements.
• Identical Voltage and Power Ratings: Both devices share 100 V breakdown voltage and 80 W power dissipation, ensuring thermal and electrical compatibility.
• Compatible Packaging: Both devices use TO-220-3 through-hole mounting, allowing direct board-level substitution without layout modification.

The lower DC current gain of the BDW93C (750 @ 5A, 3V versus 1000 @ 5A, 4V) and reduced collector cutoff current (1 mA versus 2 mA) represent minor parameter variations that do not preclude substitution in standard switching and amplification applications.

Frequently Asked Questions (FAQ)

Q: Can the BDW93C directly replace the TIP142TU in existing circuit designs?

A: Yes. The BDW93C is electrically and mechanically compatible with the TIP142TU. Both devices share identical voltage ratings (100 V), power dissipation (80 W), operating temperature (150°C), and TO-220-3 through-hole packaging. The BDW93C supports higher collector current (12 A versus 10 A), making it suitable for applications designed for the TIP142TU.

Q: What are the key differences between the TIP142TU and BDW93C?

A: The primary differences are manufacturer (onsemi versus STMicroelectronics), product status (obsolete versus active), and minor electrical parameters. The BDW93C has higher maximum collector current (12 A), lower DC current gain (750 versus 1000), and lower collector cutoff current (1 mA versus 2 mA). The BDW93C is RoHS3 compliant.

Q: Are there package compatibility concerns when substituting the BDW93C for the TIP142TU?

A: No. Both devices use TO-220-3 through-hole packaging with identical pin configurations and thermal characteristics. Direct board-level substitution is possible without PCB modification.

Q: Why is the TIP142TU classified as obsolete?

A: The TIP142TU is listed as obsolete by onsemi. The BDW93C, actively manufactured by STMicroelectronics, is the recommended substitute for ongoing procurement and new designs.

Q: Does the BDW93C meet modern regulatory standards?

A: Yes. The BDW93C is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What applications are suitable for the BDW93C as a TIP142TU replacement?

A: The BDW93C is suitable for any application previously designed for the TIP142TU, including power switching, motor control, audio amplification, and general-purpose high-current amplification circuits operating within the specified voltage and current ratings.
