BSC0802LSATMA1 Equivalent & Substitute Parts

Part Overview

The BSC0802LSATMA1 is an N-Channel MOSFET manufactured by Infineon Technologies, part of the OptiMOS™ 5 series. This device is rated for 100V drain-to-source voltage with continuous drain current of 20A at Ta and 100A at Tc, housed in an 8-PowerTDFN surface mount package. The BSC0802LSATMA1 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while offering active product status and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BSC0802LSATMA1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Drain-to-source voltage rating (Vdss) must equal or exceed 100V
• N-Channel MOSFET technology with Metal Oxide construction
• Gate threshold voltage (Vgs(th)) within specified range
• Maximum gate voltage (Vgs) rating of ±20V
• Operating temperature range of -55°C to 150°C

Mechanical Compatibility Requirements:

• Package type: 8-PowerTDFN (PG-TDSON-8-7) surface mount configuration
• Mounting type: Surface Mount

Regulatory Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected classification
• ECCN: EAR99

The ISC0802NLSATMA1 meets all mandatory substitution criteria. While this part exhibits higher continuous drain current ratings (22A at Ta, 150A at Tc) and different gate charge characteristics, these represent performance enhancements within the same electrical class and package footprint, maintaining full pin and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ISC0802NLSATMA1 is the direct substitute for the obsolete BSC0802LSATMA1. Both devices are manufactured by Infineon Technologies within the OptiMOS™ 5 series and share identical electrical class specifications (100V N-Channel MOSFET) and mechanical packaging (8-PowerTDFN surface mount).

Substitution Basis:

The ISC0802NLSATMA1 maintains full compatibility across all critical parameters: identical Vdss rating, matching gate threshold voltage, equivalent drive voltage specifications, and identical operating temperature range. The package footprint and pinout are identical, enabling direct PCB-level substitution without layout modifications.

Product Status Advantage:

The ISC0802NLSATMA1 carries Active product status, ensuring continued manufacturing support, long-term availability, and supply chain stability. The BSC0802LSATMA1 is classified as Obsolete, making the ISC0802NLSATMA1 the appropriate selection for new designs and production continuity.

Regulatory Compliance:

Both parts maintain RoHS3 Compliant and REACH Unaffected certifications, with identical ECCN classification (EAR99), ensuring regulatory equivalence for procurement and deployment.

Performance Characteristics:

The ISC0802NLSATMA1 exhibits enhanced continuous drain current ratings (22A at Ta versus 20A, and 150A at Tc versus 100A), representing performance improvement within the same electrical class. Input capacitance is reduced (5190 pF versus 6500 pF), which may provide switching speed benefits in certain applications. RDS(on) characteristics remain within comparable ranges (3.6 mOhm versus 3.4 mOhm at 50A, 10V).

Frequently Asked Questions (FAQ)

Q: Can the ISC0802NLSATMA1 be used as a direct replacement for the BSC0802LSATMA1 on existing PCBs?

A: Yes. Both devices use the identical 8-PowerTDFN (PG-TDSON-8-7) package with matching pinout and footprint. No PCB modifications are required for substitution.

Q: What is the primary reason for substituting the BSC0802LSATMA1?

A: The BSC0802LSATMA1 is classified as Obsolete. The ISC0802NLSATMA1 is the active equivalent part, ensuring continued availability and manufacturing support.

Q: Are there electrical differences between these parts that affect circuit design?

A: Both parts maintain identical Vdss (100V), Vgs(th) (2.3V max), and operating temperature range (-55°C to 150°C). The ISC0802NLSATMA1 offers higher continuous drain current ratings and lower input capacitance, representing performance enhancements. Existing circuit designs require no modification.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the BSC0802LSATMA1 and ISC0802NLSATMA1 are RoHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference in gate charge between these parts?

A: The BSC0802LSATMA1 specifies 46 nC gate charge at 4.5V, while the ISC0802NLSATMA1 specifies 73 nC at 10V. Gate charge is measured at different drive voltages, making direct comparison inappropriate. Both parts operate within the same gate voltage range (±20V).

Q: Is the ISC0802NLSATMA1 available in the same packaging options as the BSC0802LSATMA1?

A: The BSC0802LSATMA1 is supplied in Tape & Reel (TR) packaging. The ISC0802NLSATMA1 is supplied in Cut Tape (CT) and Digi-Reel® packaging. Both use the identical 8-PowerTDFN component package. Packaging format does not affect component electrical or mechanical compatibility.

Q: Can the higher drain current rating of the ISC0802NLSATMA1 cause issues in circuits designed for the BSC0802LSATMA1?

A: No. Higher current ratings represent increased capability. The ISC0802NLSATMA1 operates within the same voltage and temperature specifications, and circuits designed for the BSC0802LSATMA1 will operate within the safe operating area of the ISC0802NLSATMA1.

Q: Are there any thermal considerations when substituting these parts?

A: Both parts operate across the identical temperature range (-55°C to 150°C). The ISC0802NLSATMA1 exhibits slightly lower input capacitance, which may reduce switching losses in high-frequency applications. Thermal management requirements remain equivalent to the original design.
