2SC6011A Equivalent & Substitute Parts Reference Guide

Part Overview

The Sanken Electric USA Inc. 2SC6011A is an NPN bipolar junction transistor (BJT) specified for 230 V collector-emitter breakdown voltage, 15 A collector current, 160 W power dissipation, and a transition frequency of 20 MHz in a TO-3P through-hole package. This part is classified as “Obsolete”, creating replacement requirements for maintenance, repair, and mass-production applications. Identifying electrically and mechanically suitable substitute BJTs with matching critical parameters is necessary to ensure direct drop-in compatibility.

Substitute Part Grouping Explanation

Substitute part selection is based strictly on equivalent values for transistor type, collector-emitter breakdown voltage (max), collector current (max), mounting type, package, power dissipation, and DC current gain. Transition frequency and Vce saturation are considered for performance margin. Only parts matching NPN polarity, 230 V or greater Vce, 15 A Ic (max), similar or compatible TO-3P package, through-hole mounting, and RoHS compliance are grouped. Product status must be active or available.

Key parameters for substitution:

NPN transistor type
Maximum collector-emitter voltage (Vce)
Maximum collector current (Ic)
Power dissipation rating
Package/case and mounting type
DC current gain (hFE)
RoHS status and MSL

Engineering Selection Recommendations

Selection of substitute transistors for 2SC6011A is supported by matching device status (Active), RoHS compliance, and moisture sensitivity classification. All listed substitutes (2SC3263, 2SC5242-O(Q), NJW0281G) are RoHS Compliant or ROHS3 Compliant and either MSL 1 (Unlimited) or Not Applicable. Only parts with "Active" product status should be used as direct alternatives in applications requiring current production and compliance.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for a BJT transistor to be substituted for 2SC6011A?
A1: Transistor type (NPN), voltage rating (Vce), collector current (Ic), power dissipation, DC current gain, package type (TO-3P), mounting type (Through Hole), and RoHS status.

Q2: Are all substitute parts in the same physical package as 2SC6011A?
A2: Yes, all substitutes are specified in TO-3P-3, SC-65-3 packages, compatible with through-hole board mounting.

Q3: Do substitute parts meet the environmental and compliance status of the original?
A3: All listed substitutes are RoHS Compliant or ROHS3 Compliant with similar MSL or Not Applicable designations, meeting equivalent compliance requirements.

Q4: What is the product status significance in selection?
A4: Substitute parts with "Active" status are in-current production, supporting sourcing and continuity, whereas "Obsolete" parts require further alternatives.

Q5: Are there electrical differences between substitute parts?
A5: Substitute transistors listed have equivalent or compatible ratings for voltage, current, gain, and power. Differences in parameters such as transition frequency or Vce saturation are presented in the table and should be compared for application-specific needs.
