Engineering Selection Recommendations

The KSC1815YTA is a direct electrical and mechanical equivalent to the 2SC1815-GR-AP. Both devices meet identical specifications for maximum collector current, breakdown voltage, power dissipation, and transition frequency. Both are housed in the TO-92-3 Through Hole package and maintain RoHS3 compliance.

The primary distinction between these parts is product status: the 2SC1815-GR-AP is classified as Obsolete, while the KSC1815YTA is classified as Active. The KSC1815YTA is manufactured by onsemi, an established semiconductor manufacturer with active production and distribution channels. Selection of the KSC1815YTA ensures long-term component availability and supply chain continuity for applications currently using or requiring the 2SC1815-GR-AP.

Both devices are suitable for general-purpose NPN switching and amplification applications operating within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can the KSC1815YTA be used as a direct replacement for the 2SC1815-GR-AP?

A: Yes. The KSC1815YTA meets all critical electrical specifications including maximum collector current (150 mA), collector-emitter breakdown voltage (50 V), power dissipation (400 mW), and transition frequency (80 MHz). Both devices use the TO-92-3 Through Hole package and are RoHS3 compliant.

Q: What is the difference in DC Current Gain between these parts?

A: The 2SC1815-GR-AP specifies a minimum DC Current Gain (hFE) of 200 @ 2mA, 6V. The KSC1815YTA specifies a minimum DC Current Gain (hFE) of 70 @ 2mA, 6V. Applications requiring specific hFE characteristics must account for this difference in circuit design.

Q: Are there any package differences between these transistors?

A: Both the 2SC1815-GR-AP and KSC1815YTA use the TO-92-3 (TO-226AA) Through Hole package with formed leads. No package modifications are required for substitution.

Q: Why is the 2SC1815-GR-AP classified as Obsolete?

A: The 2SC1815-GR-AP is no longer in active production by Micro Commercial Co. The KSC1815YTA, manufactured by onsemi, provides an active alternative with equivalent electrical and mechanical specifications.

Q: What is the operating temperature range for the KSC1815YTA?

A: The KSC1815YTA operates at a maximum junction temperature (TJ) of 150°C. The 2SC1815-GR-AP operates across a range of -55°C to 150°C (TJ). Applications requiring operation below 0°C must evaluate the KSC1815YTA specifications against specific design requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2SC1815-GR-AP and KSC1815YTA are ROHS3 compliant and suitable for applications requiring RoHS compliance.
