TIP47 SL Equivalent & Substitute Parts

Part Overview

The TIP47 SL is a Bipolar (BJT) NPN transistor manufactured by Central Semiconductor Corp, rated for 250 V collector-emitter breakdown voltage and 1 A maximum collector current. This device is packaged in TO-220-3 through-hole configuration and is designed for general-purpose switching and amplification applications requiring moderate power dissipation up to 40 W.

The TIP47 SL is classified as an obsolete product. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Engineering Selection Recommendations

TIP47G (onsemi) - Primary Substitute

The TIP47G is the recommended substitute for the obsolete TIP47 SL. This part maintains complete electrical and mechanical equivalence across all specified parameters. The TIP47G is classified as an active product with current manufacturing status, ensuring long-term availability and supply chain stability.

The TIP47G carries RoHS3 compliance certification, meeting current environmental and regulatory standards for electronic components. Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), confirming regulatory compatibility.

Inventory availability of the TIP47G (2056 pcs in stock) supports immediate procurement requirements. The component is supplied in tube packaging format, suitable for automated assembly or manual installation in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the TIP47G directly replace the TIP47 SL without circuit modification?

A: Yes. The TIP47G meets all electrical specifications of the TIP47 SL, including voltage rating, current rating, gain characteristics, and saturation parameters. Both devices use identical TO-220-3 through-hole packaging. No circuit modifications are required for direct substitution.

Q: What is the difference in power rating between these parts?

A: The TIP47 SL is rated for 40 W maximum power dissipation, while the TIP47G is rated for 2 W. In applications where the TIP47 SL operates within the 2 W thermal envelope, the TIP47G is suitable. Applications requiring power dissipation exceeding 2 W must evaluate thermal management and may require alternative component selection.

Q: Are there packaging differences between TIP47 SL and TIP47G?

A: Both parts use TO-220-3 through-hole packaging. The TIP47 SL supplier device package is listed as TO-220-3, and the TIP47G supplier device package is listed as TO-220. These designations refer to the same physical package configuration suitable for identical PCB layouts and mounting hardware.

Q: What compliance certifications apply to the TIP47G?

A: The TIP47G is RoHS3 compliant and carries REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications, confirming regulatory equivalence for export and procurement purposes.

Q: Why is the TIP47 SL classified as obsolete?

A: The TIP47 SL is no longer in active production. The TIP47G serves as the current-generation equivalent, offering the same electrical performance with modern manufacturing standards and regulatory compliance.
