2STC4467 Equivalent & Substitute Parts

Part Overview

The 2STC4467 is an NPN bipolar junction transistor (BJT) manufactured by STMicroelectronics, rated for 120 V collector-emitter breakdown voltage and 8 A maximum collector current. This device is packaged in the TO-3P through-hole configuration and is rated for 80 W maximum power dissipation. The 2STC4467 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges to ensure proper circuit operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2STC4467 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Transistor type: NPN
• Voltage rating: Collector-emitter breakdown voltage ≥ 120 V
• Current rating: Maximum collector current ≥ 8 A
• Power dissipation: Maximum power ≥ 80 W
• Package type: TO-3P through-hole configuration
• Operating temperature range: ≥ 150 °C (TJ)

Secondary Compatibility Parameters:

• Vce saturation characteristics
• DC current gain (hFE)
• Transition frequency
• Collector cutoff current (ICBO)
• RoHS and regulatory compliance status

Substitute parts must satisfy all primary criteria and maintain electrical performance within acceptable operating margins. Parts that meet or exceed the specified ratings in all categories are classified as direct substitutes.

Engineering Selection Recommendations

2SC4467 (Sanken Electric USA Inc.) - Primary Substitute

The 2SC4467 manufactured by Sanken Electric USA Inc. is the direct equivalent to the obsolete STMicroelectronics 2STC4467. Both devices share identical electrical specifications: 120 V breakdown voltage, 8 A maximum collector current, 80 W power dissipation, and 20 MHz transition frequency. The Vce saturation voltage and collector cutoff current are identical. The 2SC4467 is currently in active production status with 2200 units in stock, ensuring supply continuity. Both devices are ROHS3 compliant and carry MSL rating of 1 (Unlimited). This part is the recommended substitute for direct replacement applications.

2SC3835 (Sanken Electric USA Inc.) - Conditional Substitute

The 2SC3835 is a partial substitute suitable for applications where reduced current and power requirements are acceptable. This device is rated for 7 A maximum collector current and 70 W power dissipation, representing a 12.5% reduction in current capacity and 12.5% reduction in power handling compared to the original 2STC4467. The 2SC3835 offers improved transition frequency (30 MHz versus 20 MHz) and superior Vce saturation characteristics (500 mV versus 1.5 V). However, the collector cutoff current is elevated at 100 µA compared to 10 µA in the original part. The 2SC3835 is active in production and ROHS3 compliant. This substitute is applicable only in circuits where the reduced current and power ratings do not compromise system performance.

Frequently Asked Questions (FAQ)

Q: Can the 2SC4467 (Sanken) be used as a direct replacement for the 2STC4467 (STMicroelectronics)?

A: Yes. Both devices are electrically and mechanically identical. They share the same voltage rating (120 V), current rating (8 A), power dissipation (80 W), transition frequency (20 MHz), Vce saturation characteristics, and TO-3P package configuration. The 2SC4467 is the direct substitute for the obsolete 2STC4467.

Q: What are the limitations of using the 2SC3835 as a substitute?

A: The 2SC3835 has reduced maximum collector current (7 A versus 8 A) and reduced maximum power dissipation (70 W versus 80 W). Applications requiring the full 8 A current capacity or 80 W power handling will not operate within specification with the 2SC3835. Additionally, the collector cutoff current is higher (100 µA versus 10 µA), which may affect leakage characteristics in certain circuit topologies.

Q: Are all substitute parts packaged identically?

A: Yes. All listed substitute parts use the TO-3P through-hole package configuration (TO-3P-3, SC-65-3 case designation). Physical mounting and thermal interface characteristics are identical, allowing direct mechanical substitution without circuit board modifications.

Q: Do the substitute parts meet the same regulatory and compliance standards?

A: Yes. Both the 2SC4467 and 2SC3835 are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the original 2STC4467. Both parts carry EAR99 ECCN classification.

Q: What is the difference in DC current gain between the substitute parts?

A: The 2STC4467 and 2SC3835 both specify a minimum DC current gain (hFE) of 70 @ 3 A, 4 V. The 2SC4467 (Sanken) specifies a minimum hFE of 50 @ 3 A, 4 V, representing a 28.6% reduction in guaranteed current gain. Circuits dependent on high current gain may require design adjustment when using the 2SC4467 (Sanken).

Q: Which substitute part offers the best overall performance?

A: The 2SC4467 (Sanken Electric USA Inc.) is the optimal substitute, providing complete electrical and mechanical equivalence to the original 2STC4467 with active production status and full inventory availability. The 2SC3835 is suitable only for applications with reduced current and power requirements.
