Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD14990P is determined by electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Criteria:

• Transistor polarity (NPN configuration required)
• Collector-emitter breakdown voltage (VCEO) must equal or exceed 100 V
• Maximum collector current (Ic) must equal or exceed 5 A
• Package type must be TO-220-3 Full Pack for mechanical and thermal compatibility
• Through-hole mounting requirement

Functional Compatibility Criteria:

• DC current gain (hFE) characteristics suitable for switching applications
• Saturation voltage performance acceptable for the application
• Operating temperature range supporting 150°C junction temperature

The 2SD2015 manufactured by Sanken Electric USA Inc. is identified as a substitute part. While the 2SD2015 is classified as an NPN Darlington configuration (versus standard NPN), it maintains electrical compatibility through higher collector-emitter breakdown voltage (120 V), adequate collector current rating (4 A), and identical TO-220-3 Full Pack through-hole packaging. The Darlington configuration provides enhanced current gain characteristics (2000 hFE minimum) and improved saturation performance, making it suitable for applications where the 2SD14990P was previously specified.

Parameter Comparison

Engineering Selection Recommendations

The 2SD2015 is an active product with current manufacturing support and availability, addressing the obsolescence status of the 2SD14990P. Both devices share identical TO-220-3 Full Pack through-hole packaging and operating temperature specifications, ensuring mechanical and thermal compatibility in existing circuit board layouts.

The 2SD2015 provides superior electrical performance characteristics: higher collector-emitter breakdown voltage (120 V versus 100 V), enhanced power dissipation capability (25 W versus 2 W), and significantly higher DC current gain (2000 hFE minimum versus 100 hFE minimum). The Darlington configuration of the 2SD2015 delivers lower saturation voltage (1.5 V versus 2 V), reducing power loss in switching applications.

The 2SD2015 is RoHS Compliant, meeting current environmental and regulatory requirements for new designs and production. Both devices maintain MSL Level 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements.

The maximum collector current of the 2SD2015 (4 A) is marginally lower than the 2SD14990P (5 A). Circuit designs operating at or near the 5 A maximum specification of the 2SD14990P require evaluation to confirm the 4 A rating of the 2SD2015 is acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 2SD2015 directly replace the 2SD14990P in existing designs?

A: The 2SD2015 is mechanically and electrically compatible with the 2SD14990P in TO-220-3 Full Pack through-hole applications. Both devices share identical package geometry and pin configuration. However, the maximum collector current specification differs (4 A versus 5 A). Designs operating below 4 A collector current support direct substitution. Designs requiring the full 5 A specification require circuit evaluation.

Q: What is the primary difference between the 2SD14990P and 2SD2015?

A: The 2SD14990P is a standard NPN bipolar junction transistor, while the 2SD2015 is an NPN Darlington configuration. The Darlington structure provides higher current gain (2000 hFE minimum versus 100 hFE minimum) and lower saturation voltage (1.5 V versus 2 V), resulting in improved switching efficiency and reduced base drive requirements.

Q: Are there thermal management differences between these devices?

A: Both devices support identical maximum junction temperature (150°C) and share the same TO-220-3 Full Pack package. The 2SD2015 offers significantly higher power dissipation capability (25 W versus 2 W), providing greater thermal margin in power-limited applications. Identical heatsinking and thermal management approaches apply to both devices.

Q: Does the 2SD2015 require different circuit design considerations?

A: The Darlington configuration of the 2SD2015 exhibits higher current gain, requiring lower base drive current for equivalent collector current levels. Applications designed for the 2SD14990P base drive specifications operate within acceptable parameters with the 2SD2015, though base current requirements are reduced. The lower saturation voltage of the 2SD2015 reduces power dissipation in saturated switching applications.

Q: What is the availability status of these devices?

A: The 2SD14990P is classified as obsolete with limited inventory availability. The 2SD2015 is an active product with current manufacturing support and ongoing availability, making it the preferred choice for new designs and production continuity.

Q: Are moisture sensitivity and handling requirements identical?

A: Both the 2SD14990P and 2SD2015 are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Identical handling, storage, and packaging requirements apply to both devices.
