TIP107 Equivalent & Substitute Parts

Part Overview

The TIP107 is a PNP Darlington bipolar junction transistor manufactured by onsemi, housed in a TO-220-3 package for through-hole mounting applications. This component is rated for 100 V collector-emitter breakdown voltage and 8 A maximum collector current, with a maximum power dissipation of 2 W. The onsemi TIP107 carries an obsolete product status, necessitating identification of equivalent alternatives from active product lines to ensure design continuity and procurement availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TIP107 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: PNP - Darlington configuration
• Current - Collector (Ic) (Max): 8 A minimum
• Voltage - Collector Emitter Breakdown (Max): 100 V minimum
• Power - Max: 2 W minimum
• Package / Case: TO-220-3
• Mounting Type: Through Hole

Acceptable Variation Parameters:

• Vce Saturation (Max): May vary within device specifications
• Current - Collector Cutoff (Max): May vary within device specifications
• DC Current Gain (hFE) (Min): May vary provided minimum 1000 is maintained at specified test conditions
• Operating Temperature Range: May extend beyond -65°C to 150°C

Substitute parts are classified into two categories:

Direct Equivalents: Parts meeting all critical matching parameters with identical electrical performance at rated conditions.

Similar Alternatives: Parts meeting all critical matching parameters with acceptable variations in secondary electrical characteristics that do not compromise circuit functionality within the original design envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TIP107G (onsemi)

The TIP107G represents the direct equivalent to the obsolete onsemi TIP107. This part maintains identical electrical specifications across all critical parameters including collector current, breakdown voltage, saturation voltage, and current gain. The TIP107G carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection of TIP107G provides pin-for-pin compatibility with zero design modification requirements.

Secondary Recommendation: TIP107 (STMicroelectronics)

The STMicroelectronics TIP107 serves as a cross-manufacturer direct equivalent with identical electrical performance to the original onsemi device. This part is actively manufactured and ROHS3 compliant. The STMicroelectronics variant provides an alternative supply source while maintaining complete electrical and mechanical compatibility.

Alternative Consideration: TIP137 (STMicroelectronics)

The TIP137 qualifies as a similar alternative meeting all critical matching parameters. This part exhibits acceptable variations in secondary electrical characteristics: higher collector cutoff current (500µA versus 50µA) and higher saturation voltage (4V @ 30mA, 6A versus 2.5V @ 80mA, 8A). The TIP137 is suitable for applications where these parameter variations do not compromise circuit performance. This part is actively manufactured with ROHS3 compliance and represents the highest inventory availability among all alternatives.

Frequently Asked Questions (FAQ)

Q: Can TIP107G be used as a direct replacement for the obsolete onsemi TIP107?

A: Yes. The TIP107G is a direct equivalent with identical electrical specifications and TO-220-3 package configuration. No circuit modifications are required.

Q: What is the difference between TIP107G and the STMicroelectronics TIP107?

A: Both parts are direct equivalents with identical electrical performance. The primary difference is manufacturer source. TIP107G is manufactured by onsemi; the STMicroelectronics variant is manufactured by STMicroelectronics. Both are ROHS3 compliant and actively produced.

Q: Can TIP137 replace TIP107 in all applications?

A: TIP137 meets the critical electrical parameters (8 A collector current, 100 V breakdown voltage, 2 W power rating, TO-220-3 package). However, TIP137 exhibits higher collector cutoff current and higher saturation voltage. Verify that these variations are acceptable for the specific circuit application before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: TIP107G, STMicroelectronics TIP107, and TIP137 are all ROHS3 compliant. The original onsemi TIP107 is RoHS non-compliant due to its obsolete status.

Q: What is the difference in saturation voltage between TIP107 and TIP137?

A: TIP107 exhibits 2.5V saturation voltage at 80mA base current and 8A collector current. TIP137 exhibits 4V saturation voltage at 30mA base current and 6A collector current. These variations reflect different device design characteristics and should be evaluated against circuit requirements.

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

A: Yes. All substitute parts use TO-220-3 package configuration with through-hole mounting. Physical board layout compatibility is maintained across all alternatives.

Q: Which substitute part offers the best long-term availability?

A: TIP137 currently maintains the highest inventory level (67,710 pieces) among all alternatives, followed by STMicroelectronics TIP107 (28,650 pieces) and TIP107G (9,094 pieces). Inventory levels are subject to change based on market demand and manufacturing schedules.
