2STW1693 Equivalent & Substitute Parts

Part Overview

The 2STW1693 is a PNP bipolar junction transistor manufactured by STMicroelectronics, rated for 80 V collector-emitter breakdown voltage and 6 A maximum collector current. This device is packaged in a TO-247-3 through-hole configuration and is designed for 60 W power dissipation applications. The 2STW1693 is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2STW1693 is determined by the following critical parameters:

Transistor Polarity: The substitute must be PNP type to maintain circuit functionality.

Voltage Rating: The substitute must have a collector-emitter breakdown voltage equal to or greater than 80 V to ensure safe operation within the original design envelope.

Current Rating: The substitute must have a maximum collector current equal to or greater than 6 A to support the required load conditions.

Power Dissipation: The substitute must have a maximum power rating equal to or greater than 60 W to handle thermal requirements.

Frequency Response: The substitute must have a transition frequency equal to or greater than 20 MHz to maintain signal integrity in the intended application.

Package Compatibility: The substitute must be compatible with through-hole mounting and PCB layouts designed for the original package footprint, or the design must accommodate package differences.

The TIP36C meets the electrical parameter requirements for substitution, with higher ratings in voltage (100 V), current (25 A), and power (125 W) capabilities. However, package differences and compliance status require engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The TIP36C exceeds the electrical specifications of the 2STW1693 in voltage, current, and power ratings. All critical electrical parameters are satisfied for direct functional substitution.

Frequency Consideration: The TIP36C operates at 3 MHz transition frequency, which is lower than the 2STW1693 at 20 MHz. Applications requiring higher frequency response may experience performance degradation with this substitute.

Package Difference: The 2STW1693 uses TO-247-3 packaging while the TIP36C uses TO-218-3 packaging. These packages have different pin configurations and footprints. PCB layout modifications are required for physical substitution.

Product Status: The TIP36C is classified as active and maintains current manufacturing support, providing long-term availability compared to the obsolete 2STW1693.

Compliance Status: The 2STW1693 is ROHS3 compliant, while the TIP36C is RoHS non-compliant. Applications subject to RoHS requirements must account for this compliance difference.

Frequently Asked Questions (FAQ)

Q: Can the TIP36C directly replace the 2STW1693 without circuit modifications?

A: The TIP36C satisfies all electrical parameter requirements for functional substitution. However, the different package types (TO-247-3 versus TO-218-3) require PCB layout modifications. Pin-to-pin electrical compatibility must be verified for the specific application circuit.

Q: Why does the TIP36C have lower frequency response than the 2STW1693?

A: The TIP36C is designed for higher current and power applications (25 A, 125 W) compared to the 2STW1693 (6 A, 60 W). Higher current capability typically results in lower transition frequency. Applications operating above 3 MHz may require alternative substitutes with higher frequency ratings.

Q: What is the significance of the RoHS compliance difference?

A: The 2STW1693 is ROHS3 compliant, indicating it meets RoHS Directive requirements for restricted hazardous substances. The TIP36C is RoHS non-compliant. Products destined for markets with RoHS requirements must use compliant components. This difference may restrict the use of TIP36C in certain applications or regions.

Q: Are there package-specific considerations for substitution?

A: Yes. The TO-247-3 package (2STW1693) and TO-218-3 package (TIP36C) have different pin layouts and mounting footprints. Mechanical compatibility with existing PCB designs cannot be assumed. Physical evaluation of package dimensions and pin spacing is required before implementation.

Q: What applications are suitable for the TIP36C as a substitute?

A: The TIP36C is suitable for applications requiring PNP transistor functionality at voltages up to 100 V and currents up to 25 A, with operating frequencies up to 3 MHz. Applications requiring higher frequency response or RoHS compliance should evaluate alternative substitutes.
