D44VH10 Equivalent & Substitute Parts

Part Overview

The D44VH10 is an NPN bipolar junction transistor (BJT) manufactured by onsemi, rated for 80 V collector-emitter breakdown voltage and 15 A maximum collector current in a TO-220-3 through-hole package. This device is classified as obsolete, indicating discontinuation from active production. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Substitute Part Grouping Explanation

Substitution of the D44VH10 is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

• Transistor Type: Must be NPN configuration
• Current Rating: Collector current (Ic) must equal or exceed 15 A maximum
• Voltage Rating: Collector-emitter breakdown voltage must equal or exceed 80 V
• Saturation Characteristics: Vce saturation must not exceed 400mV at specified base and collector currents
• Current Gain: DC current gain (hFE) minimum must meet or exceed 20 @ 4A, 1V
• Power Dissipation: Maximum power rating must equal or exceed 83 W
• Frequency Response: Transition frequency must equal or exceed 50MHz
• Temperature Range: Operating temperature range must encompass -55°C to 150°C
• Package: TO-220-3 through-hole package required for mechanical compatibility
• Mounting: Through-hole mounting type required

Parameter Comparison

Engineering Selection Recommendations

The D44VH10G is a direct electrical and mechanical equivalent to the D44VH10. All electrical parameters, including current rating, voltage rating, saturation characteristics, current gain, power dissipation, frequency response, and operating temperature range, are identical. Both devices utilize the TO-220-3 through-hole package and are manufactured by onsemi.

The primary distinction between these parts is product status and regulatory compliance. The D44VH10 is obsolete and RoHS non-compliant, while the D44VH10G is active in production and ROHS3 compliant. For new designs and production applications, the D44VH10G is the appropriate selection. The D44VH10G maintains full backward compatibility with existing circuit designs specified for the D44VH10, requiring no circuit modifications or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the D44VH10G be used as a direct replacement for the D44VH10?

A: Yes. The D44VH10G is electrically and mechanically identical to the D44VH10. All electrical parameters match exactly, and both devices use the TO-220-3 through-hole package. No circuit modifications are required.

Q: What is the primary reason to substitute the D44VH10?

A: The D44VH10 is classified as obsolete and is no longer in active production. The D44VH10G provides continued access to equivalent functionality with active manufacturing status and improved regulatory compliance.

Q: Are there packaging differences between the D44VH10 and D44VH10G?

A: Both parts use the TO-220-3 through-hole package. The D44VH10G is supplied in tube packaging, while the D44VH10 packaging specification was not provided. Both are mechanically compatible with standard TO-220 mounting configurations.

Q: Does the D44VH10G meet current regulatory requirements?

A: Yes. The D44VH10G is ROHS3 compliant and REACH unaffected. The D44VH10 is RoHS non-compliant. For applications requiring regulatory compliance, the D44VH10G is the appropriate selection.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Current rating (15 A), voltage rating (80 V), saturation voltage (400mV @ 400mA, 8A), DC current gain (20 @ 4A, 1V), power dissipation (83 W), transition frequency (50MHz), and operating temperature range (-55°C to 150°C) are identical.

Q: Can the D44VH10G be used in existing PCB designs without modification?

A: Yes. The D44VH10G maintains identical electrical specifications and uses the same TO-220-3 through-hole package. No PCB layout modifications are required.
