TIP3055-S Equivalent & Substitute Parts Reference

Part Overview

The TIP3055-S, manufactured by Bourns Inc., is an NPN bipolar junction transistor (BJT) designed for through-hole mounting in a SOT-93 package. Its key ratings include a collector current of 15 A and a collector-emitter breakdown voltage of 60 V. The TIP3055-S is classified as obsolete. For applications requiring continued supply or active lifecycle status, it is necessary to identify substitute or equivalent parts with directly matching parameters for electrical, mechanical, and compliance criteria.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on matching specifications for transistor type, maximum collector current, voltage rating, collector-emitter saturation voltage, cutoff current, DC current gain, power rating, operating temperature range, mounting method, package style, and compliance with ROHS3. Only parts listed with direct matching values for these key parameters are considered substitutes.

Key parameters considered:

• Transistor Type: NPN
• Current - Collector (Ic) (Max): 15 A
• Voltage - Collector Emitter Breakdown (Max): 60 V
• Vce Saturation (Max) @ Ib, Ic: 3V @ 3.3A, 10A
• Current - Collector Cutoff (Max): 700µA
• DC Current Gain (hFE) (Min): 20 @ 4A, 4V
• Power - Max
• Operating Temperature: -65°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: TO-218-3, TO-247-3
• RoHS Status

Engineering Selection Recommendations

Selection is based on matching ROHS3 compliance and product status. The TIP3055-S is obsolete, while the TIP3055G is active and ROHS3 compliant, supporting ongoing requirements for environmental and supply chain certifications.

Frequently Asked Questions (FAQ)

Q1: How are equivalent and substitute transistors selected in this category?
A1: Substitutes are selected strictly by matching electrical parameters (NPN, collector current, voltage, gain, saturation voltage, cutoff current), mechanical attributes (mounting type, package style), and compliance status.

Q2: Are different package types such as TO-218-3 and TO-247-3 compatible for substitution?
A2: Packages must be compared for mechanical and PCB compatibility. Only package types listed in the parameter comparison are considered.

Q3: What is the significance of ROHS3 compliance when selecting a substitute?
A3: ROHS3 compliance ensures the selected part meets current environmental regulations, which is mandatory in regulated markets.

Q4: Does product status affect equivalency?
A4: Active status is prioritized over obsolete parts to ensure continued production and supply chain security.

Q5: Why must parameters such as collector current and voltage be exactly matched?
A5: These parameters define the safe and intended electrical operation of the transistor in the application.

Q6: Are there differences in electrical performance between TIP3055-S and TIP3055G?
A6: Only parameters explicitly listed have been compared. Both parts match in all mandatory fields required for substitution.
