BSC0702LSATMA1 Equivalent & Substitute Parts

Part Overview

The BSC0702LSATMA1 is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 60V drain-to-source voltage and 100A continuous drain current. This device is housed in a PG-TDSON-8 surface mount package and is part of the OptiMOS™ series. The part is classified as "Not For New Designs," indicating that Infineon has discontinued active development support. Finding equivalent or substitute components is necessary for applications requiring continued supply, design flexibility, or alternative sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BSC0702LSATMA1 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: Must be N-Channel MOSFET
• Drain-to-Source Voltage (Vdss): Substitute must equal or exceed 60V
• Continuous Drain Current (Id): Must support 100A at 25°C
• RDS(on): Lower or equal values ensure equivalent or superior performance
• Gate Threshold Voltage (Vgs(th)): Must fall within compatible drive voltage ranges
• Gate Charge (Qg): Lower values reduce drive circuit stress
• Operating Temperature Range: Must cover -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Package Classification: 8-PowerTDFN family packages
• Pin Configuration: Compatible with PG-TDSON-8 footprint

Regulatory & Supply Criteria:

• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): Level 1 (Unlimited) preferred
• Product Status: Active status preferred for long-term availability

The MCAC100N08YA-TP meets these substitution criteria with the following considerations: it provides higher voltage rating (80V vs. 60V), maintains 100A current capability, and is classified as Active product status, ensuring continued supply and support.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The BSC0702LSATMA1 carries a "Not For New Designs" status from Infineon Technologies, indicating that the manufacturer no longer actively supports this component for new applications. This status creates supply chain risk and limits access to technical support and design resources. The MCAC100N08YA-TP is classified as Active, ensuring continued availability and manufacturer support.

Electrical Performance Assessment

The MCAC100N08YA-TP substitute maintains the critical 100A continuous drain current specification required by the application. The higher Vdss rating (80V vs. 60V) provides additional voltage margin and is fully compatible with 60V circuit designs. However, the substitute exhibits higher RDS(on) (4.5 mOhm vs. 2.3 mOhm) and increased gate charge (90 nC vs. 30 nC), which may impact thermal performance and gate drive circuit requirements. These differences must be evaluated within the specific application context.

Regulatory Compliance

Both components meet RoHS3 compliance and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent handling and storage requirements. Both are classified under identical HTSUS and ECCN codes, supporting equivalent regulatory treatment.

Package and Mechanical Compatibility

Both devices use 8-pin PowerTDFN surface mount packages. While both are designated as 8-PowerTDFN, the main part uses PG-TDSON-8 and the substitute uses DFN5060 designation. PCB footprint verification is required to confirm pin-to-pin compatibility and thermal pad alignment before design implementation.

Frequently Asked Questions (FAQ)

Q: Can the MCAC100N08YA-TP directly replace the BSC0702LSATMA1 in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB footprint compatibility between PG-TDSON-8 and DFN5060 packages, (2) gate driver capability to supply the higher gate charge (90 nC vs. 30 nC), and (3) thermal design adequacy given the higher RDS(on) specification. Electrical functionality is compatible for 60V applications due to the substitute's higher voltage rating.

Q: What is the impact of the higher RDS(on) in the MCAC100N08YA-TP?

A: Higher RDS(on) (4.5 mOhm vs. 2.3 mOhm) increases conduction losses and heat generation. In high-current applications, this may require enhanced thermal management (larger heatsink, improved PCB thermal design, or forced cooling). Calculate power dissipation using I²R losses at the application's actual operating current to determine thermal impact.

Q: Why does the substitute have higher gate charge?

A: Gate charge (Qg) is a function of the device's internal capacitance and switching characteristics. The MCAC100N08YA-TP's higher gate charge (90 nC vs. 30 nC) reflects different internal design. The gate driver circuit must supply sufficient current to charge the gate within the required switching time. Verify that the existing gate driver can deliver the required charge without exceeding maximum gate voltage (±20V for both devices).

Q: Are the packages truly compatible?

A: Both devices are 8-pin PowerTDFN packages, but the specific designations (PG-TDSON-8 vs. DFN5060) may indicate different thermal pad sizes or pin spacing. Obtain detailed package drawings from both manufacturers and verify footprint dimensions, pin pitch, and thermal pad area before PCB layout. Pin assignment must also be confirmed to be identical.

Q: What is the significance of "Not For New Designs" status?

A: This status indicates that Infineon has ended active development and support for the BSC0702LSATMA1. While existing inventory may be available, the manufacturer will not release new design documentation, application notes, or technical support. Long-term supply cannot be guaranteed. Substitution with an Active-status component (MCAC100N08YA-TP) mitigates supply chain and support risks.

Q: How do the operating temperature ranges compare?

A: Both devices operate across -55°C to 150°C (TJ), providing identical thermal operating windows. No temperature-related compatibility issues exist between the two components.

Q: What certifications and compliance standards apply to both parts?

A: Both the BSC0702LSATMA1 and MCAC100N08YA-TP are RoHS3 compliant, REACH unaffected, and classified under EAR99 export control. Both carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory and compliance requirements are equivalent.
