Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SC2383-O-AP are selected based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters (Must Match or Exceed):

• Transistor Type: NPN
• Current - Collector (Ic) Max: 1 A minimum
• Voltage - Collector Emitter Breakdown (Max): 160 V minimum
• Power - Max: 900 mW minimum
• DC Current Gain (hFE) Min @ Ic, Vce: 100 @ 200mA, 5V minimum

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-226-3 or TO-92-3 Long Body (Formed Leads)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

The KSC2383OTA and KSC2383YTA, both manufactured by onsemi, satisfy all substitution criteria. Both devices are active products with enhanced performance characteristics, including higher transition frequency (100 MHz versus 20 MHz) and improved collector cutoff current specifications. These parts are direct functional replacements suitable for applications previously designed with the 2SC2383-O-AP.

Parameter Comparison

Engineering Selection Recommendations

Both KSC2383OTA and KSC2383YTA are suitable substitutes for the obsolete 2SC2383-O-AP based on electrical and mechanical parameter equivalence. The selection between these two onsemi alternatives depends on application-specific DC current gain requirements:

KSC2383OTA Selection Criteria:

• Applications requiring minimum DC current gain of 100 @ 200mA, 5V
• Active product status with established supply chain availability
• ROHS3 compliant with REACH unaffected designation

KSC2383YTA Selection Criteria:

• Applications benefiting from higher DC current gain of 160 @ 200mA, 5V
• Significantly higher inventory availability (155,200 pcs in stock)
• Active product status with ROHS3 compliance and REACH unaffected designation
• Enhanced performance margin for gain-dependent circuit designs

Both substitute parts exceed the original 2SC2383-O-AP specifications in transition frequency (100 MHz versus 20 MHz) and collector cutoff current performance (1µA versus 10µA), providing improved high-frequency response and reduced leakage characteristics. The through-hole TO-92-3 package configuration ensures direct mechanical compatibility with existing PCB layouts designed for the original component.

Frequently Asked Questions (FAQ)

Q: Can KSC2383OTA and KSC2383YTA be used interchangeably with 2SC2383-O-AP?

A: Both onsemi parts are direct functional substitutes for the obsolete 2SC2383-O-AP. They meet or exceed all critical electrical parameters including collector current (1 A), breakdown voltage (160 V), and power dissipation (900 mW). The through-hole TO-92-3 package ensures mechanical compatibility with existing PCB designs.

Q: What is the difference between KSC2383OTA and KSC2383YTA?

A: The primary difference is DC current gain specification. KSC2383OTA is rated for minimum hFE of 100 @ 200mA, 5V, while KSC2383YTA is rated for minimum hFE of 160 @ 200mA, 5V. Both parts share identical maximum ratings and package configuration. KSC2383YTA offers higher inventory availability and enhanced gain margin for circuit designs sensitive to transistor gain variation.

Q: Are the substitute parts RoHS compliant?

A: Both KSC2383OTA and KSC2383YTA are ROHS3 compliant, matching the compliance status of the original 2SC2383-O-AP. Both onsemi parts are also REACH unaffected.

Q: Does the higher transition frequency of the substitute parts affect circuit operation?

A: The substitute parts feature 100 MHz transition frequency compared to the original 20 MHz specification. This enhanced frequency response is a performance improvement that does not degrade circuit operation in applications designed for the original 20 MHz device. Higher transition frequency provides additional margin for high-frequency signal handling.

Q: Are the package dimensions identical between the original and substitute parts?

A: All three parts use the TO-226-3 or TO-92-3 Long Body (Formed Leads) package configuration. The through-hole mounting type and lead spacing are identical, ensuring direct PCB compatibility without layout modifications.

Q: What is the operating temperature range for the substitute parts?

A: The KSC2383OTA and KSC2383YTA are rated for maximum junction temperature (TJ) of 150°C. The original 2SC2383-O-AP specifies an operating range of -55°C to 150°C. For applications requiring the full -55°C lower temperature limit, thermal design verification is necessary to confirm the substitute parts operate within specified junction temperature limits at minimum ambient conditions.
