• Voltage - Collector Emitter Breakdown (Max): 50 V
• Vce Saturation (Max) @ Ib, Ic: 300mV @ 10mA, 100mA
• Current - Collector Cutoff (Max): 100nA (ICBO)
• Power - Max: 400 mW
• Frequency - Transition: 80MHz
• Mounting Type: Through Hole
• Package / Case: TO-226-3, TO-92-3 (TO-226AA) Formed Leads

The KSA1015YTA manufactured by onsemi meets all critical electrical specifications and package requirements, establishing it as a direct functional equivalent for the obsolete 2SA1015-O-AP.

Parameter Comparison

Engineering Selection Recommendations

The KSA1015YTA is the direct substitute for the obsolete 2SA1015-O-AP. Both components are ROHS3 Compliant and share identical electrical ratings and package specifications. The KSA1015YTA maintains Active product status, ensuring long-term availability and supply chain continuity. The DC Current Gain (hFE) of the KSA1015YTA at 120 @ 2mA, 6V exceeds the minimum specification of 70 @ 2mA, 6V, providing additional performance margin. Both devices are suitable for Through Hole assembly and are compatible with standard PCB layouts designed for TO-92-3 packages.

Frequently Asked Questions (FAQ)

Q: Can the KSA1015YTA be used as a direct replacement for the 2SA1015-O-AP in existing designs?

A: Yes. The KSA1015YTA meets all electrical specifications and package requirements of the 2SA1015-O-AP. Both components are PNP transistors with identical maximum ratings for collector current (150 mA), collector-emitter breakdown voltage (50 V), saturation voltage, power dissipation (400 mW), and transition frequency (80MHz). The TO-92-3 package is identical, enabling direct PCB compatibility.

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

A: The 2SA1015-O-AP specifies a minimum DC Current Gain (hFE) of 70 @ 2mA, 6V. The KSA1015YTA specifies a minimum of 120 @ 2mA, 6V. The higher gain of the KSA1015YTA does not create incompatibility; it provides additional performance margin for circuit operation.

Q: Are there any compliance or certification differences?

A: Both the 2SA1015-O-AP and KSA1015YTA are ROHS3 Compliant. The KSA1015YTA carries REACH Unaffected status. Both components share the same ECCN (EAR99) and HTSUS (8541.21.0095) classifications.

Q: Why is the 2SA1015-O-AP classified as Obsolete?

A: The 2SA1015-O-AP is listed as Obsolete by the manufacturer. The KSA1015YTA, manufactured by onsemi, is an Active product with equivalent specifications and serves as the recommended substitute for ongoing production and design requirements.

Q: Are the packaging formats different between these parts?

A: Both components use Through Hole mounting with TO-226-3 and TO-92-3 (TO-226AA) Formed Leads packages. The KSA1015YTA is supplied in Cut Tape (CT) packaging, while the 2SA1015-O-AP packaging format is not specified. This difference does not affect electrical compatibility or PCB assembly.
