TIP42C-S Equivalent & Substitute Parts Reference

Part Overview

The TIP42C-S (Bourns Inc.) is a PNP bipolar junction transistor in the TO-220 package, with a maximum collector-emitter voltage of 100 V and a maximum collector current of 6 A. The product is marked as obsolete, making it necessary to identify suitable alternative models to ensure continued production support and field maintenance.

Substitute Part Grouping Explanation

Substitute and equivalent part selection is based exclusively on matching the following critical parameters: transistor type (PNP), maximum collector-emitter voltage (100 V), maximum collector current (≥ 6 A), V_CE(sat) at the same test conditions, DC current gain (hFE), maximum collector cutoff current, mounting style (Through Hole), package/case (TO-220-3), and compliance status (RoHS3). Only parts meeting all listed values are shown as direct substitutes. Variance in power rating, frequency, or other non-listed attributes is neither considered nor substituted unless also specified.

Engineering Selection Recommendations

All listed substitutes are active and ROHS3 compliant. Each candidate meets the TO-220-3 through-hole package, PNP polarity, 100 V collector-emitter breakdown voltage, and 6 A or higher collector current requirements, strictly as defined by the input parameters. Selection can proceed based on company-approved supplier lists and inventory status, as no additional product status or compliance restrictions are present.

Frequently Asked Questions (FAQ)

Q: What are the main criteria for selecting a substitute for TIP42C-S?
A: The substitute must match PNP polarity, maximum collector-emitter voltage (100 V), maximum collector current (≥ 6 A), V_CE(sat), hFE (DC current gain), cutoff current, mounting type (Through Hole), package (TO-220-3), and RoHS3 compliance.

Q: Are all listed substitutes in the same package as TIP42C-S?
A: All listed substitutes use the TO-220-3 through-hole package, consistent with the TIP42C-S mechanical requirements.

Q: Are there differences in performance parameters across substitutes?
A: Only parameters explicitly provided (such as Ic, V_CE, hFE, cutoff current, power rating, and compliance) are considered. The presented parts match all substitution requirements.

Q: Is RoHS3 compliance consistent across all substitute parts?
A: Yes. All shown substitute parts are designated as ROHS3 Compliant.

Q: Can these substitutes be used in existing designs without mechanical modification?
A: Each substitute part shares the TO-220-3 through-hole package with the TIP42C-S, supporting design interchange on this basis.
