Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BSC026NE2LS5ATMA1 are qualified based on the following criteria:

Electrical Compatibility Parameters:

• Drain-to-source voltage rating equal to or greater than 25V
• Continuous drain current capability at Ta and Tc meeting or exceeding the original specification
• On-resistance (Rds On) within acceptable operating parameters
• Gate threshold voltage compatible with existing drive circuitry
• Maximum gate voltage rating accommodating the control signal range

Thermal and Mechanical Compatibility:

• Operating temperature range spanning -55°C to 150°C
• Surface mount package configuration
• RoHS3 compliance and MSL rating of 1

Substitution Logic: The CSD16321Q5 and CSD16414Q5 from Texas Instruments are qualified substitutes because they maintain the 25V Vdss rating, exceed the continuous drain current specifications, operate within the same temperature range, and comply with identical regulatory standards. Both devices are manufactured in 8-VSON-CLIP surface mount packages compatible with the original application footprint.

Parameter Comparison

Engineering Selection Recommendations

BSC026NE2LS5ATMA1 (Primary Component): The original Infineon OptiMOS™ device is recommended for applications requiring the specified electrical characteristics with established supply chain continuity. This component maintains Active product status with full regulatory compliance including RoHS3 and REACH Unaffected designation.

CSD16414Q5 (Preferred Substitute): The CSD16414Q5 from Texas Instruments NexFET™ series is the primary substitute option. This device provides superior on-resistance performance (1.9 mOhm vs. 2.6 mOhm), higher continuous drain current ratings (34A Ta / 100A Tc vs. 24A Ta / 82A Tc), and maintains compatibility with the ±16V gate voltage specification of the original component. The device is supplied in Tape & Reel packaging and maintains identical RoHS3 compliance and MSL rating.

CSD16321Q5 (Secondary Substitute): The CSD16321Q5 serves as an alternative substitute with comparable electrical performance (31A Ta / 100A Tc continuous drain current) and improved on-resistance (2.4 mOhm). This device is supplied in Cut Tape & Digi-Reel® packaging. The gate voltage rating is limited to +10V / -8V, which may restrict application in circuits requiring the full ±16V range of the original component.

All substitute parts maintain Active product status, RoHS3 compliance, MSL 1 rating, and operate across the -55°C to 150°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can CSD16321Q5 and CSD16414Q5 be used interchangeably with BSC026NE2LS5ATMA1?

A: Both Texas Instruments devices are qualified substitutes for the Infineon BSC026NE2LS5ATMA1 based on electrical parameter compatibility. The CSD16414Q5 is preferred due to its ±16V gate voltage rating matching the original specification. The CSD16321Q5 is suitable for applications operating within its +10V / -8V gate voltage range.

Q: What are the key differences in on-resistance performance?

A: The CSD16414Q5 exhibits the lowest on-resistance at 1.9 mOhm (@ 30A, 10V), compared to 2.6 mOhm for the BSC026NE2LS5ATMA1 and 2.4 mOhm for the CSD16321Q5. Lower on-resistance reduces power dissipation and heat generation in high-current applications.

Q: Are the package footprints compatible?

A: The BSC026NE2LS5ATMA1 uses a PG-TDSON-8-7 package, while both substitute parts use 8-VSON-CLIP (5x6) packages. Although both are 8-pin surface mount configurations, PCB layout verification is required to confirm mechanical compatibility with the existing footprint.

Q: What is the impact of higher input capacitance in the substitute parts?

A: The CSD16321Q5 and CSD16414Q5 exhibit higher input capacitance (3100 pF and 3650 pF respectively) compared to the BSC026NE2LS5ATMA1 (1100 pF). Higher capacitance increases gate charge requirements and may affect switching speed in high-frequency applications. Gate drive circuitry must be evaluated for compatibility.

Q: Do all parts meet the same regulatory requirements?

A: Yes. The BSC026NE2LS5ATMA1, CSD16321Q5, and CSD16414Q5 are all RoHS3 compliant, REACH Unaffected, classified as EAR99, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which substitute is recommended for new designs?

A: The CSD16414Q5 is recommended for new designs due to its superior on-resistance performance, higher current ratings, and full compatibility with the ±16V gate voltage specification. The device is supplied in standard Tape & Reel packaging suitable for automated assembly.
