TIP101G Equivalent & Substitute Parts

Part Overview

The TIP101G is an NPN Darlington bipolar junction transistor manufactured by onsemi, rated for 80 V collector-emitter breakdown voltage and 8 A maximum collector current in a TO-220-3 through-hole package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The TIP101G is suitable for applications requiring moderate voltage and current switching with Darlington configuration benefits, including high current gain and simplified base drive requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP101G is determined by electrical and mechanical compatibility across the following critical parameters:

Primary Substitution Criteria:

• Transistor Type: NPN - Darlington configuration
• Package / Case: TO-220-3 form factor
• Mounting Type: Through Hole
• Voltage - Collector Emitter Breakdown: Equal to or greater than 80 V
• Current - Collector (Ic) (Max): Equal to or greater than 8 A
• DC Current Gain (hFE): Minimum 1000 @ specified operating point
• Operating Temperature Range: Minimum -65°C to 150°C
• RoHS Compliance: ROHS3 Compliant

Direct Equivalent: TIP102G (onsemi) provides identical electrical specifications with upgraded voltage rating (100 V) and active product status.

Similar Substitute: TIP102 (STMicroelectronics) matches all critical electrical parameters with active product status and equivalent thermal performance.

Alternative Substitute: BDX53B (STMicroelectronics) matches voltage and current ratings with identical package, though power dissipation capability differs (60 W vs. 2 W).

Parameter Comparison

Engineering Selection Recommendations

TIP102G (onsemi) is the primary direct equivalent for TIP101G replacement. This part maintains identical electrical specifications with the exception of an increased voltage rating (100 V vs. 80 V), providing enhanced design margin. TIP102G carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

TIP102 (STMicroelectronics) serves as a cross-manufacturer equivalent with identical electrical performance at the 8 A, 100 V operating point. This part is actively manufactured and maintains full ROHS3 compliance. The operating temperature specification differs slightly (150°C maximum vs. -65°C to 150°C range), which may be relevant for applications requiring extended low-temperature operation.

BDX53B (STMicroelectronics) functions as an alternative substitute when higher power dissipation capability is required. This part matches the 80 V, 8 A core ratings but provides 60 W maximum power rating compared to 2 W for the TIP101G. The BDX53B exhibits higher collector cutoff current (500 µA vs. 50 µA) and lower minimum DC current gain (750 vs. 1000), which may affect base drive requirements in specific circuit topologies.

All substitute parts are ROHS3 compliant and maintain TO-220-3 through-hole packaging, ensuring mechanical and thermal interface compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can TIP102G directly replace TIP101G in existing designs?

A: Yes. TIP102G is a direct equivalent with identical electrical specifications and package configuration. The higher voltage rating (100 V vs. 80 V) provides additional design margin without affecting circuit operation in applications rated for 80 V operation.

Q: What is the primary difference between TIP102G and TIP102?

A: Both parts are electrically equivalent NPN Darlington transistors with 100 V, 8 A ratings. TIP102G is manufactured by onsemi, while TIP102 is manufactured by STMicroelectronics. The operating temperature specification for TIP102 is listed as 150°C maximum, whereas TIP102G specifies -65°C to 150°C range. Both are ROHS3 compliant and actively produced.

Q: When should BDX53B be selected instead of TIP102G?

A: BDX53B is selected when circuit design requires higher power dissipation capability (60 W vs. 2 W). Applications involving continuous high-current switching or thermal stress benefit from the BDX53B's enhanced power rating. However, the BDX53B exhibits different saturation characteristics and higher collector cutoff current, requiring circuit verification for base drive and leakage current performance.

Q: Are all substitute parts available in the same packaging?

A: Yes. TIP101G, TIP102G, TIP102, and BDX53B are all supplied in TO-220-3 through-hole packages, ensuring mechanical compatibility with existing PCB layouts and thermal management solutions.

Q: What compliance certifications apply to these substitute parts?

A: All listed parts are ROHS3 compliant and REACH unaffected. These certifications ensure regulatory compliance for applications subject to environmental and hazardous substance restrictions.

Q: Does the TIP101G obsolete status affect substitute part selection?

A: Yes. The obsolete status of TIP101G necessitates substitution for new procurement and long-term design support. TIP102G, TIP102, and BDX53B are all actively manufactured, ensuring reliable supply chain availability and continued technical support from manufacturers.
