BD244C Equivalent & Substitute Parts

Part Overview

The BD244C is a PNP bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 6 A maximum collector current in a TO-220-3 through-hole package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The BD244C delivers 65 W maximum power dissipation and operates at junction temperatures up to 150°C.

Substitute Part Grouping Explanation

Substitution of the BD244C is determined by matching the following critical electrical and mechanical parameters:

Primary Matching Criteria:

Transistor polarity: PNP
Collector-emitter breakdown voltage: 100 V minimum
Collector current rating: 6 A minimum
Package type: TO-220-3 through-hole configuration
Vce saturation characteristics at specified bias conditions
DC current gain (hFE) at rated operating points

Substitution Categories:

Direct Equivalents maintain all primary electrical specifications and are pin-compatible replacements. These parts satisfy the full electrical envelope of the BD244C.

Similar Alternatives share the same voltage and package specifications but differ in current rating or power dissipation. These parts are suitable for applications where the full 6 A current capability is not required, or where lower power dissipation is acceptable.

Engineering Selection Recommendations

BD244CG (onsemi) is the primary direct equivalent for the obsolete BD244C. This part is manufactured by the same supplier, maintains identical electrical specifications including 6 A collector current and 65 W power dissipation, and is currently in active production status. BD244CG is RoHS3 compliant and carries REACH Unaffected certification. This part provides the most direct replacement path with no design modifications required.

TIP42CG (onsemi) and TIP42C-BP (Micro Commercial Co) are direct electrical equivalents with respect to voltage, current, and saturation characteristics. Both parts support 6 A collector current and 100 V breakdown voltage. The primary difference is reduced power dissipation rating (2 W versus 65 W). These parts are suitable for applications where thermal management requirements are less stringent than the original design. TIP42CG is RoHS3 compliant; TIP42C-BP is RoHS3 compliant with MSL 1 rating.

TIP32CG (onsemi) supports 3 A maximum collector current with 100 V breakdown voltage. This part is applicable only to designs where the full 6 A current capability is not required. TIP32CG is RoHS3 compliant and carries REACH Unaffected certification.

TIP30CG (onsemi) supports 1 A maximum collector current with 100 V breakdown voltage. This part is applicable only to low-current applications. TIP30CG is RoHS3 compliant and carries REACH Unaffected certification.

BD912 (NTE Electronics, Inc) supports 15 A collector current and 90 W power dissipation, exceeding the BD244C specifications. This part is suitable for applications requiring higher current capacity. BD912 is RoHS non-compliant and carries MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can BD244CG be used as a direct replacement for BD244C?

A: Yes. BD244CG is manufactured by onsemi and maintains identical electrical specifications: 6 A collector current, 100 V breakdown voltage, 65 W power dissipation, and TO-220-3 package configuration. BD244CG is in active production status, whereas BD244C is obsolete. No circuit modifications are required.

Q: What is the difference between BD244CG and TIP42CG?

A: Both parts support 6 A collector current and 100 V breakdown voltage in TO-220-3 packages. The primary difference is power dissipation rating: BD244CG is rated for 65 W, while TIP42CG is rated for 2 W. TIP42CG is suitable for applications with lower power dissipation requirements. Vce saturation characteristics differ slightly at specified bias points.

Q: Can TIP32CG replace BD244C in all applications?

A: No. TIP32CG supports only 3 A maximum collector current, compared to 6 A for BD244C. TIP32CG is suitable only for applications where the design current requirement does not exceed 3 A. Both parts share 100 V breakdown voltage and TO-220-3 package configuration.

Q: Is BD912 a suitable replacement for BD244C?

A: BD912 exceeds BD244C specifications in current (15 A versus 6 A) and power dissipation (90 W versus 65 W). BD912 is electrically compatible but is not a direct equivalent. BD912 is RoHS non-compliant, whereas BD244C is REACH Unaffected. Use BD912 only when higher current capacity is required.

Q: What are the compliance differences between substitute parts?

A: BD244CG, TIP42CG, TIP32CG, and TIP30CG are RoHS3 compliant. TIP42C-BP is RoHS3 compliant with MSL 1 rating. BD912 is RoHS non-compliant. All parts carry REACH Unaffected or equivalent certification except where noted. Verify compliance requirements for your specific application before selection.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts are supplied in TO-220-3 through-hole packages. Packaging format (tube, bag) varies by manufacturer and supplier. Verify packaging requirements for your assembly process before procurement.
