TIP147T Equivalent & Substitute Parts

Part Overview

The TIP147T is a PNP Darlington bipolar junction transistor manufactured by STMicroelectronics, designed for high-current switching and amplification applications. This device operates at 100 V collector-emitter breakdown voltage with a maximum collector current of 10 A and 90 W power dissipation in a Through Hole TO-220-3 package. The TIP147T maintains Active product status with full availability and ROHS3 compliance. Substitute parts are identified when equivalent electrical performance is required, inventory constraints exist, or design flexibility is needed within the specified parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP147T is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Transistor Type: PNP - Darlington configuration
• Voltage - Collector Emitter Breakdown: 100 V minimum
• Package / Case: TO-220-3 Through Hole
• Mounting Type: Through Hole
• DC Current Gain (hFE): 1000 minimum @ 5A, 4V
• Current - Collector Cutoff (Max): 2 mA maximum
• Vce Saturation: 3V @ specified base and collector currents
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current - Collector (Ic) (Max): Equal to or greater than 10 A
• Power - Max: Equal to or greater than 90 W
• Operating Temperature Range: Must include 150°C maximum junction temperature
• Product Status: Active or Obsolete (both acceptable for substitution)

The BDW47G meets all mandatory equivalence criteria and exceeds current and power specifications, qualifying as a direct substitute within the defined parameter envelope.

Engineering Selection Recommendations

TIP147T Selection: The TIP147T is the primary choice for new designs and applications requiring active product status with guaranteed long-term availability. STMicroelectronics maintains this component in active production with 21,370 units in current inventory. Full ROHS3 compliance and REACH unaffected status confirm regulatory alignment for industrial and commercial applications.

BDW47G Selection: The BDW47G functions as a direct electrical substitute where the TIP147T is unavailable or where higher collector current capacity (15 A versus 10 A) provides design margin. The BDW47G carries Obsolete product status, indicating limited future availability. This substitute is suitable for legacy system maintenance, repair applications, or designs where the higher current rating provides operational benefit. ROHS3 compliance and REACH unaffected status maintain regulatory equivalence.

Compliance Considerations: Both parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to environmental and hazardous substance restrictions. Moisture Sensitivity Level (MSL) 1 (Unlimited) applies to both components, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can the BDW47G replace the TIP147T in existing designs?

A: Yes. The BDW47G meets all mandatory electrical parameters including voltage rating (100 V), transistor type (PNP Darlington), current gain (1000 @ 5A, 4V), saturation voltage (3V @ 10A), and package configuration (TO-220-3 Through Hole). The substitute exceeds the collector current specification (15 A versus 10 A), providing additional design margin.

Q: What is the primary difference between these parts?

A: The BDW47G provides higher maximum collector current (15 A) and includes transition frequency specification (4MHz), while the TIP147T maintains Active product status with greater inventory availability. Both devices operate identically within the TIP147T's specified current envelope (10 A maximum).

Q: Are there thermal management differences?

A: Both parts specify identical maximum junction temperature (150°C) and package type (TO-220-3). Thermal management requirements remain unchanged during substitution. The BDW47G's 85 W maximum power rating is within the TIP147T's 90 W specification at the 10 A operating point.

Q: Does product status affect substitution suitability?

A: Product status indicates availability trajectory. The TIP147T (Active) ensures continued supply for new designs. The BDW47G (Obsolete) is suitable for repair and maintenance applications but not recommended for new production designs requiring long-term component availability.

Q: Are packaging and mounting identical?

A: Yes. Both parts use TO-220-3 Through Hole packages with identical pin configurations and thermal characteristics. No PCB layout or mechanical modifications are required for substitution.

Q: Do regulatory certifications differ?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. Regulatory requirements are fully satisfied by either component.
