TIP36C Equivalent & Substitute Parts

Part Overview

The TIP36C is a PNP bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 25 A maximum collector current. This device is packaged in the TO-218-3 (SOT-93) through-hole configuration and delivers 125 W maximum power dissipation. The TIP36C is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitution of the TIP36C is determined by strict equivalence across the following electrical and mechanical parameters:

Transistor Type: PNP configuration required
Current Rating: 25 A maximum collector current
Voltage Rating: 100 V collector-emitter breakdown voltage
Power Dissipation: 125 W maximum
Frequency Response: 3 MHz transition frequency
Temperature Range: -65°C to 150°C operating range
Mounting Configuration: Through-hole technology

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalent: Parts from onsemi that maintain identical electrical specifications with alternative packaging configurations (TO-247-3 vs. TO-218-3).

Similar Manufacturer Alternatives: Parts from alternative manufacturers (NTE Electronics, Inc and Central Semiconductor Corp) that meet the core electrical requirements within the specified parameter envelope, packaged in TO-218-3 configuration.

Engineering Selection Recommendations

TIP36CG (onsemi) is the primary recommended substitute for the obsolete TIP36C. This part maintains identical electrical specifications and is manufactured by the original equipment supplier. The TIP36CG is classified as active product status and achieves ROHS3 compliance, supporting modern regulatory requirements. The alternative TO-247-3 package provides enhanced thermal performance through increased lead surface area, beneficial for high-power applications. PCB layout modifications are required to accommodate the different package footprint.

TIP36C (NTE Electronics, Inc) and TIP36C SL (Central Semiconductor Corp) are secondary alternatives that maintain TO-218-3 package compatibility with the original TIP36C, eliminating PCB redesign requirements. Both parts are active products from established alternative manufacturers. These options are suitable for applications where package footprint compatibility is a primary constraint. Note that both alternatives are RoHS non-compliant, consistent with the original TIP36C classification.

Selection between substitute options depends on design priorities: regulatory compliance and thermal performance favor the TIP36CG, while package compatibility and minimal redesign favor the NTE Electronics or Central Semiconductor alternatives.

Frequently Asked Questions (FAQ)

Q: Can the TIP36CG replace the TIP36C in existing designs without circuit modification?

A: The TIP36CG maintains identical electrical specifications and can replace the TIP36C functionally. However, the TO-247-3 package differs from the TO-218-3 package, requiring PCB layout modifications for mounting and thermal management. Pin configuration and electrical performance are equivalent.

Q: What is the primary difference between TIP36CG and the alternative manufacturer options?

A: The TIP36CG is manufactured by onsemi, the original equipment supplier, and achieves ROHS3 compliance. The NTE Electronics and Central Semiconductor alternatives maintain the original TO-218-3 package footprint but remain RoHS non-compliant. All three options meet the core electrical specifications.

Q: Are there thermal performance differences between the TO-218-3 and TO-247-3 packages?

A: The TO-247-3 package (TIP36CG) provides increased lead surface area compared to TO-218-3, supporting improved thermal dissipation. Package selection should align with thermal design requirements and PCB layout constraints.

Q: Can NTE Electronics TIP36C and Central Semiconductor TIP36C SL be used interchangeably?

A: Both parts maintain identical electrical specifications and TO-218-3 package compatibility. They are functionally interchangeable within the circuit design. Inventory and supplier availability may determine practical selection.

Q: What compliance considerations apply to substitute part selection?

A: The TIP36CG achieves ROHS3 compliance, supporting modern regulatory environments. The NTE Electronics and Central Semiconductor alternatives remain RoHS non-compliant. Compliance requirements should drive substitute selection for new designs targeting regulated markets.

Q: Is the DC Current Gain (hFE) specification identical across all substitute options?

A: The onsemi TIP36C and TIP36CG specify hFE minimum of 15 @ 15A, 4V. The NTE Electronics and Central Semiconductor alternatives specify hFE minimum of 10 @ 15A, 4V. This represents a lower guaranteed gain in the alternative manufacturer options and should be evaluated for circuit performance impact.
