KSH47TF Equivalent & Substitute Parts

Part Overview

The KSH47TF is an NPN bipolar junction transistor manufactured by onsemi, rated for 250V collector-emitter breakdown voltage and 1A maximum collector current in a surface mount DPAK package. This device is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts maintain identical electrical specifications and mechanical packaging while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSH47TF is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): 250 V
• Current - Collector (Ic) (Max): 1 A
• Vce Saturation (Max) @ Ib, Ic: 1V @ 200mA, 1A
• DC Current Gain (hFE) (Min) @ Ic, Vce: 30 @ 300mA, 10V
• Frequency - Transition: 10MHz
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount

All identified substitute parts maintain these parameters within the specified tolerances. Packaging format variations (Tube, Tape & Reel, Cut Tape) represent different distribution methods and do not affect electrical or mechanical compatibility. The primary distinction between substitutes is product status: MJD47G, MJD47T4G, NJVMJD47T4G, and MJD47T4 are active products, whereas KSH47TF is obsolete.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (onsemi Manufacturer):

MJD47G, MJD47T4G, and NJVMJD47T4G are direct onsemi equivalents to the KSH47TF. These parts maintain identical electrical specifications and DPAK packaging. All three are active products with ROHS3 compliance and REACH unaffected status. Selection between these three onsemi alternatives is determined by packaging format availability: MJD47G is supplied in Tube format, while MJD47T4G and NJVMJD47T4G are supplied in Tape & Reel format. MJD47T4G and NJVMJD47T4G offer extended operating temperature range (-65°C ~ 150°C) compared to the KSH47TF specification (150°C maximum).

Alternative Substitute (STMicroelectronics Manufacturer):

MJD47T4 manufactured by STMicroelectronics is electrically equivalent across all critical parameters with the exception of maximum power dissipation (15W versus 1.56W) and collector cutoff current (100µA versus 200µA). This part is active, ROHS3 compliant, and REACH unaffected. The higher power rating provides additional thermal margin in applications. MJD47T4 is supplied in Cut Tape and Digi-Reel format.

All substitute parts are suitable for direct replacement in applications designed for the KSH47TF, with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can MJD47G, MJD47T4G, NJVMJD47T4G, and MJD47T4 be used interchangeably with KSH47TF?

A: Yes. All substitute parts maintain identical electrical specifications for collector-emitter breakdown voltage (250V), maximum collector current (1A), saturation voltage, DC current gain, and transition frequency. All are packaged in TO-252-3 DPAK format with identical pinout and mechanical dimensions. No circuit modifications are required for substitution.

Q: What is the difference between MJD47G, MJD47T4G, and NJVMJD47T4G?

A: These three parts are electrically identical onsemi products. The primary differences are packaging format and operating temperature range. MJD47G is supplied in Tube format, while MJD47T4G and NJVMJD47T4G are supplied in Tape & Reel format. MJD47T4G and NJVMJD47T4G specify an extended operating temperature range of -65°C to 150°C, compared to the KSH47TF maximum of 150°C. Selection is based on procurement requirements and application temperature specifications.

Q: Why does MJD47T4 have a higher power rating (15W) than the KSH47TF (1.56W)?

A: MJD47T4 is manufactured by STMicroelectronics and features enhanced thermal characteristics within the same DPAK package. The higher power rating reflects improved thermal performance. This part is suitable for applications requiring additional thermal margin. All other electrical parameters remain equivalent to KSH47TF.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MJD47G, MJD47T4G, NJVMJD47T4G, and MJD47T4 are all ROHS3 compliant and REACH unaffected, matching the compliance status of KSH47TF.

Q: What is the difference between Tube, Tape & Reel, and Cut Tape packaging?

A: These represent different distribution and handling formats. Tube packaging is used for manual handling and small-quantity applications. Tape & Reel format is used for automated assembly processes with standard reel specifications. Cut Tape & Digi-Reel format provides flexibility for intermediate quantities. All formats contain electrically identical components; selection is based on assembly process requirements and order quantities.

Q: Is the KSH47TF still available for purchase?

A: KSH47TF is classified as obsolete. Active substitute parts (MJD47G, MJD47T4G, NJVMJD47T4G, MJD47T4) are recommended for new designs and ongoing production. These substitutes provide equivalent functionality with improved product lifecycle status and availability.

Q: Can MJD47T4 from STMicroelectronics be used in place of the onsemi alternatives?

A: Yes. MJD47T4 is electrically equivalent across all critical parameters and maintains identical DPAK packaging and pinout. The higher power dissipation rating (15W) and lower collector cutoff current (100µA) represent performance enhancements. Selection between onsemi and STMicroelectronics alternatives is based on supplier availability, procurement agreements, and application thermal requirements.
