MJF15030 Equivalent & Substitute Parts

Part Overview

The MJF15030 is an NPN bipolar junction transistor (BJT) manufactured by onsemi, designed for general-purpose switching and amplification applications. The device features a maximum collector current of 8 A, collector-emitter breakdown voltage of 150 V, and maximum power dissipation of 2 W in a through-hole TO-220FP package.

The MJF15030 carries an obsolete product status, indicating that onsemi has discontinued active production and support for this part number. This obsolescence necessitates identification of equivalent substitute components that maintain electrical and mechanical compatibility with existing designs while offering active product status and current manufacturing support.

Substitute Part Grouping Explanation

Substitution of the MJF15030 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Required Match):

• Transistor type: NPN
• Maximum collector current (Ic): 8 A
• Collector-emitter breakdown voltage: 150 V
• Vce saturation characteristics: 500mV @ 100mA, 1A
• Collector cutoff current: 10 µA
• DC current gain (hFE): 20 @ 4A, 2V minimum
• Maximum power dissipation: 2 W
• Transition frequency: 30 MHz
• Operating temperature range: -65°C to 150°C

Mechanical Parameters (Required Match):

• Mounting type: Through Hole
• Package designation: TO-220-3 Full Pack
• Supplier device package: TO-220FP

The MJF15030G meets all specified electrical and mechanical parameters and qualifies as a direct equivalent substitute.

Engineering Selection Recommendations

The MJF15030G is the direct equivalent substitute for the obsolete MJF15030. Both parts are manufactured by onsemi and exhibit identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The MJF15030 is classified as obsolete, whereas the MJF15030G maintains active product status. Active status ensures continued manufacturing availability, technical support, and supply chain reliability for new designs and production runs.

Compliance Consideration: The MJF15030G achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in restricted substance directives. The original MJF15030 is RoHS non-compliant. Both parts maintain REACH Unaffected status.

Packaging Consideration: The MJF15030G is supplied in tube packaging, whereas the original MJF15030 packaging specification is not explicitly defined. Both parts utilize the TO-220FP supplier device package and TO-220-3 Full Pack case designation, ensuring mechanical and thermal compatibility in through-hole PCB applications.

For new designs, production transitions, or component replenishment, the MJF15030G provides equivalent electrical performance with the advantage of active manufacturing status and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the MJF15030G be used as a direct replacement for the MJF15030 in existing circuit designs?

A: Yes. The MJF15030G exhibits identical electrical specifications and mechanical package configuration. All critical parameters—collector current, breakdown voltage, saturation characteristics, current gain, power dissipation, transition frequency, and operating temperature range—are equivalent. The TO-220FP package ensures identical PCB footprint and thermal interface compatibility.

Q: What is the primary reason for substituting the MJF15030?

A: The MJF15030 carries obsolete product status, indicating discontinued manufacturing by onsemi. The MJF15030G maintains active production status, ensuring supply availability and technical support for current and future applications.

Q: Are there any electrical performance differences between the MJF15030 and MJF15030G?

A: No. Both parts are specified with identical electrical parameters: 8 A maximum collector current, 150 V breakdown voltage, 500 mV saturation voltage, 10 µA cutoff current, 20 minimum DC current gain, 2 W power dissipation, 30 MHz transition frequency, and -65°C to 150°C operating temperature range.

Q: What is the difference in packaging between these parts?

A: The MJF15030G is supplied in tube packaging, while the original MJF15030 packaging type is not specified in the available data. Both parts use the TO-220FP supplier device package and TO-220-3 Full Pack case designation. Tube packaging is a standard industry format for through-hole components and does not affect electrical or mechanical compatibility.

Q: Does the MJF15030G meet current regulatory compliance standards?

A: Yes. The MJF15030G is ROHS3 compliant, meeting current restricted substance directive requirements. Both parts maintain REACH Unaffected status. The original MJF15030 is RoHS non-compliant, making the MJF15030G the preferred choice for applications requiring regulatory compliance.

Q: Are the MJF15030 and MJF15030G pin-compatible?

A: Yes. Both parts utilize the TO-220-3 Full Pack configuration with identical pin assignments and mechanical dimensions. Direct PCB substitution is possible without circuit modification or layout changes.

Q: What is the inventory status of these parts?

A: The MJF15030 has 3193 pieces in stock as new original inventory. The MJF15030G has 1516 pieces in stock as new original inventory. Given the obsolete status of the MJF15030, the MJF15030G represents the recommended long-term supply source.
