Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD1012F-SPA-AC is determined by electrical parameter compatibility within the following criteria:

Electrical Compatibility Requirements:

• Transistor type must be NPN
• Voltage - Collector Emitter Breakdown rating must equal or exceed 15 V
• Current - Collector (Ic) maximum rating must equal or exceed 700 mA
• Power dissipation capability must equal or exceed 250 mW
• DC Current Gain (hFE) must meet or exceed 160 @ 50mA, 2V
• Vce Saturation characteristics must support switching applications at specified current levels

Mechanical Compatibility Considerations:

• Package type and mounting method may differ based on application requirements
• Through-hole and surface-mount variants are evaluated separately
• Pin configuration must support direct functional replacement or circuit adaptation

The 15C02CH-TL-E qualifies as a functional substitute based on superior electrical ratings across all critical parameters, despite differences in mounting technology and package form factor.

Parameter Comparison

Engineering Selection Recommendations

Electrical Suitability: The 15C02CH-TL-E demonstrates superior electrical performance across all measured parameters. Maximum collector current rating increases from 700 mA to 1 A, power dissipation capability increases from 250 mW to 700 mW, and DC current gain improves from 160 to 300. Transition frequency increases from 250 MHz to 440 MHz. These enhancements provide design margin and support higher-performance applications without electrical compromise.

Compliance and Certification Status: Both devices are manufactured by onsemi and carry identical REACH and ECCN classifications (REACH Unaffected, EAR99). The 15C02CH-TL-E includes RoHS3 compliance certification, whereas the 2SD1012F-SPA-AC does not specify RoHS status. Both devices are classified as obsolete products.

Packaging and Integration Considerations: The primary distinction between these devices is mounting technology. The 2SD1012F-SPA-AC uses through-hole mounting (3-SIP package), while the 15C02CH-TL-E employs surface-mount technology (SC-96 package). Circuit board redesign is required for direct substitution. Through-hole applications may require adapter solutions or board layout modification to accommodate surface-mount components.

Thermal Performance: The 15C02CH-TL-E supports higher maximum junction temperature (150°C versus 125°C), enabling operation in elevated ambient conditions.

Frequently Asked Questions (FAQ)

Q: Can the 15C02CH-TL-E directly replace the 2SD1012F-SPA-AC in existing circuit boards?

A: Direct replacement is not possible without circuit board modification. The 2SD1012F-SPA-AC uses through-hole mounting (3-SIP package), while the 15C02CH-TL-E uses surface-mount technology (SC-96 package). Pin configuration and physical layout differ. Circuit board redesign or adapter solutions are required.

Q: What are the key electrical advantages of the 15C02CH-TL-E substitute?

A: The 15C02CH-TL-E provides higher maximum collector current (1 A versus 700 mA), greater power dissipation capability (700 mW versus 250 mW), improved DC current gain (300 versus 160), and higher transition frequency (440 MHz versus 250 MHz). These parameters enable the substitute to handle higher-performance applications while maintaining voltage compatibility at 15 V.

Q: Are both devices suitable for new designs?

A: Both the 2SD1012F-SPA-AC and 15C02CH-TL-E are classified as obsolete products. Neither device is recommended for new designs. Current production alternatives from onsemi should be evaluated for new applications.

Q: What is the significance of the lower Vce saturation voltage in the 15C02CH-TL-E?

A: The 15C02CH-TL-E exhibits higher Vce saturation (280mV @ 20mA, 400mA) compared to the 2SD1012F-SPA-AC (80mV @ 10mA, 100mA). This difference reflects measurement at different current levels. At equivalent operating points, saturation characteristics must be verified for switching applications requiring minimal voltage drop.

Q: Does the 15C02CH-TL-E require different biasing circuit design?

A: The 15C02CH-TL-E exhibits higher DC current gain (300 versus 160), which affects base current requirements. Biasing circuits must be recalculated to account for the improved gain characteristics. Lower base current may be required to achieve equivalent collector current levels.

Q: What is the moisture sensitivity level for both devices?

A: Both devices are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there compliance differences between these devices?

A: The 15C02CH-TL-E includes RoHS3 compliance certification. The 2SD1012F-SPA-AC does not specify RoHS status. Both devices are REACH Unaffected and classified as EAR99 for export control purposes.
