Engineering Selection Recommendations

The KSP92TA is a direct electrical and mechanical substitute for the 2N6519-AP. Both devices share identical maximum ratings for collector current (500 mA), collector-emitter breakdown voltage (300 V), and power dissipation (625 mW). Package configuration is identical (TO-92-3 Through Hole), ensuring mechanical compatibility in existing PCB layouts and through-hole assembly processes.

The KSP92TA offers the advantage of active product status from onsemi, providing assured long-term availability and supply chain continuity compared to the obsolete 2N6519-AP. Both parts maintain ROHS3 compliance and identical ECCN and HTSUS classifications, supporting regulatory and trade compliance requirements.

The transition frequency of the KSP92TA (50 MHz) exceeds that of the 2N6519-AP (40 MHz), representing an enhancement in high-frequency performance characteristics without compromising any specified maximum ratings.

Frequently Asked Questions (FAQ)

Q: Can the KSP92TA directly replace the 2N6519-AP in existing designs?

A: Yes. The KSP92TA meets all electrical maximum ratings and shares identical package configuration (TO-92-3). No circuit modifications are required for direct substitution.

Q: Are there differences in DC current gain (hFE) between these parts?

A: Yes. The 2N6519-AP specifies a minimum hFE of 45 @ 30 mA, 10 V, while the KSP92TA specifies a minimum hFE of 25 @ 30 mA, 10 V. Circuit designs relying on specific gain characteristics should account for this difference in bias network calculations.

Q: What is the difference in saturation voltage between these transistors?

A: The 2N6519-AP specifies Vce saturation of 1 V @ 5 mA, 50 mA, while the KSP92TA specifies 500 mV @ 2 mA, 20 mA. The KSP92TA exhibits lower saturation voltage under its specified test conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2N6519-AP and KSP92TA are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the packaging difference between these parts?

A: Both parts use identical TO-92-3 (TO-226AA) Through Hole package configuration with formed leads. No mechanical or assembly modifications are necessary when substituting between these devices.

Q: Why is the 2N6519-AP classified as obsolete?

A: The 2N6519-AP is no longer in active production by Micro Commercial Co. The KSP92TA from onsemi provides equivalent electrical performance with active product status and assured availability.

Q: Are there any temperature range limitations when substituting?

A: The 2N6519-AP operates from -55°C to 150°C. The KSP92TA operates to 150°C maximum. For applications requiring operation below 0°C, the lower temperature limit of the 2N6519-AP should be verified against specific system requirements.
