KSC2331YSHTA Equivalent & Substitute Parts

Part Overview

The KSC2331YSHTA is an NPN bipolar junction transistor manufactured by onsemi, rated for 60 V collector-emitter breakdown voltage and 700 mA maximum collector current. This device is packaged in a TO-92-3 through-hole configuration and is designed for general-purpose switching and amplification applications. The KSC2331YSHTA is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support and production continuity. Active substitute parts with identical or superior electrical characteristics are available to maintain circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

KSC1008YTA (onsemi)

The KSC1008YTA is an active product manufactured by onsemi, the original manufacturer of the KSC2331YSHTA. This substitute meets all electrical specifications and is RoHS3 compliant. The KSC1008YTA exhibits improved saturation voltage performance (400 mV versus 700 mV at specified conditions), resulting in lower power dissipation during switching operations. This part is available in Cut Tape (CT) packaging with 2,100 units in stock.

KSC1008CYTA (Fairchild Semiconductor)

The KSC1008CYTA is an active product manufactured by Fairchild Semiconductor. This substitute meets all electrical specifications and shares identical electrical characteristics with the KSC1008YTA. The KSC1008CYTA provides the same improved saturation voltage performance and is available in Bulk packaging with 55,100 units in stock, offering superior availability for high-volume applications.

Both substitutes are electrically compatible with the KSC2331YSHTA and support direct pin-for-pin replacement in TO-92-3 through-hole circuit implementations. Selection between KSC1008YTA and KSC1008CYTA depends on packaging requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the KSC1008YTA or KSC1008CYTA be used as direct replacements for the KSC2331YSHTA?

A: Yes. Both substitute parts are electrically and mechanically compatible. They share identical voltage ratings (60 V), current ratings (700 mA), frequency response (50 MHz), and DC current gain specifications. Both are packaged in TO-92-3 through-hole configuration, enabling direct pin-for-pin replacement.

Q: What is the difference between the KSC1008YTA and KSC1008CYTA?

A: The primary differences are manufacturer and packaging format. The KSC1008YTA is manufactured by onsemi and supplied in Cut Tape (CT) packaging. The KSC1008CYTA is manufactured by Fairchild Semiconductor and supplied in Bulk packaging. Electrically, both parts are identical and interchangeable.

Q: Why do the substitute parts have lower maximum power ratings (800 mW) compared to the KSC2331YSHTA (1 W)?

A: The substitute parts have lower maximum power dissipation specifications. However, both substitutes exhibit superior saturation voltage performance (400 mV versus 700 mV), which reduces power dissipation during active switching. Circuit designs operating within the 700 mA current and 60 V voltage limits will function correctly with either substitute.

Q: Are the substitute parts available in the same TO-92-3 package?

A: Yes. Both KSC1008YTA and KSC1008CYTA are packaged in TO-92-3 through-hole configuration with formed leads, identical to the KSC2331YSHTA. No PCB layout modifications are required for substitution.

Q: What is the product status of the substitute parts?

A: Both KSC1008YTA and KSC1008CYTA are classified as Active products, ensuring ongoing availability and manufacturing support. The KSC2331YSHTA is classified as Obsolete, making these active substitutes the appropriate choice for new designs and production continuity.

Q: Do the substitute parts meet RoHS compliance requirements?

A: The KSC1008YTA is RoHS3 compliant. The KSC1008CYTA compliance status is not specified in the provided data. Both parts are REACH Unaffected and classified under ECCN EAR99.
