2N6338G Equivalent & Substitute Parts

Part Overview

The 2N6338G is an NPN bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 25 A maximum collector current. This device is packaged in the TO-204 (TO-3) through-hole format and is designed for high-power switching and amplification applications with a maximum power dissipation of 200 W. The 2N6338G is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N6338G is determined by equivalence in the following critical parameters:

• Transistor Type: NPN configuration
• Voltage Rating: 100 V collector-emitter breakdown voltage
• Current Rating: 25 A maximum collector current
• Power Dissipation: 200 W maximum
• Frequency Response: 40 MHz transition frequency
• DC Current Gain: Minimum 30 hFE at specified conditions
• Saturation Characteristics: Vce saturation performance
• Package Type: TO-204 (TO-3) through-hole format

The substitute parts 2N6338, 2N6339, and 2N6340 are all manufactured by Microchip Technology and share the same base product designations as the original onsemi device. These parts maintain electrical equivalence within the NPN transistor category and are suitable for direct replacement in applications requiring the specified voltage, current, and power parameters.

Parameter Comparison

Engineering Selection Recommendations

2N6338 (Microchip Technology): This part is the direct equivalent designation and is currently in active production status. Inventory availability is substantial at 1900 pieces. Selection of this part provides continuity with the original 2N6338G electrical specifications while transitioning to an active product line. Note that this part carries RoHS non-compliant status, which may require evaluation against project compliance requirements.

2N6339 (Microchip Technology): This substitute maintains NPN transistor classification and is available in active production status with 759 pieces in inventory. RoHS non-compliance status is consistent with the 2N6338 variant. This part is suitable for applications where the base product number 2N6339 designation is acceptable.

2N6340 (Microchip Technology): This substitute is also in active production with 653 pieces available. It maintains the same electrical category and RoHS compliance profile as the 2N6339. Selection is appropriate where the 2N6340 base product number meets design specifications.

All three Microchip substitutes provide active product status, addressing the obsolescence of the original 2N6338G. Compliance considerations regarding RoHS status must be evaluated against specific project requirements, as the substitute parts differ from the original ROHS3 compliant designation.

Frequently Asked Questions (FAQ)

Q: Can the 2N6338 (Microchip) directly replace the 2N6338G (onsemi)?

A: Yes. Both parts share the same base product number 2N6338 and maintain equivalent NPN transistor specifications for voltage, current, and power ratings. The primary difference is manufacturer and product status transition from obsolete to active production.

Q: What is the significance of the RoHS compliance difference between the original and substitute parts?

A: The 2N6338G is ROHS3 compliant, while the Microchip substitutes are RoHS non-compliant. This distinction must be evaluated against project environmental and regulatory requirements. Applications subject to RoHS directives may require compliance verification before substitution.

Q: Are there electrical performance differences between 2N6338, 2N6339, and 2N6340?

A: The provided specifications indicate all three parts are classified as NPN transistors within the same electrical category. Detailed electrical parameter specifications beyond the base transistor type are not provided in the substitute part data. Consultation of complete datasheets is necessary to confirm parameter equivalence for specific application requirements.

Q: Does the TO-204 (TO-3) package remain consistent across all substitute parts?

A: The package information provided for the substitute parts does not explicitly specify TO-204 or TO-3 designation. Verification of package compatibility is required before substitution to ensure mechanical fit in existing circuit board layouts and thermal management designs.

Q: What inventory considerations apply to these substitutes?

A: All three Microchip substitutes maintain active inventory status: 2N6338 (1900 pcs), 2N6339 (759 pcs), and 2N6340 (653 pcs). The 2N6338 variant offers the highest inventory availability. Procurement planning should account for these quantities relative to production volume requirements.

Q: Are there export control or tariff implications for these substitutes?

A: All parts, including the original 2N6338G and the three Microchip substitutes, carry identical ECCN (EAR99) and HTSUS (8541.29.00xx) classifications. Export control and tariff treatment remain consistent across the substitution options.
