Substitute Part Grouping Explanation

Substitution of the AON6202 is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss): Must equal or exceed 30V
Continuous Drain Current: Must meet or exceed 21A (Ta) and 24A (Tc) ratings
On-Resistance (Rds On): Lower or equivalent values ensure compatible switching performance
Gate Threshold Voltage (Vgs(th)): Must fall within compatible operating range
Package Type: Surface mount 8-pin configurations with compatible pinout and thermal characteristics
Operating Temperature Range: Must support -55°C to 150°C minimum

Secondary Compatibility Parameters:

Gate Charge (Qg): Lower values indicate faster switching capability
Input Capacitance (Ciss): Affects gate drive requirements
Power Dissipation: Must support thermal requirements of the application

Substitute parts are grouped into two categories: direct functional equivalents with matching or superior electrical performance, and alternative package options that maintain electrical compatibility while offering different thermal or manufacturing characteristics.

Engineering Selection Recommendations

Tier 1 - Direct Functional Equivalents (Recommended for Replacement):

AON6558 (Alpha & Omega Semiconductor Inc.) provides the closest functional match to the AON6202. Both devices share the same 30V Vdss rating, 8-DFN (5x6) package footprint, and comparable drain current specifications (25A Ta / 28A Tc versus 21A Ta / 24A Tc). The AON6558 exhibits superior on-resistance (5.1 mOhm versus 5.5 mOhm) and lower gate charge (25 nC versus 33 nC), resulting in improved switching efficiency. However, the AON6558 is classified as Not For New Designs, limiting its suitability for new product development.

Tier 2 - Active Production Alternatives (Preferred for New Designs):

BSC0902NSATMA1 (Infineon Technologies OptiMOS™ series) is an active production device offering superior electrical performance. The 30V Vdss rating matches the AON6202, with continuous drain current of 24A (Ta) and 100A (Tc). The significantly lower on-resistance of 2.6 mOhm at 30A, 10V provides reduced power dissipation. The package is PG-TDSON-8-6, which differs from the original 8-DFN footprint and requires PCB layout verification. ROHS3 compliance and active product status support long-term availability.

CSD17577Q5A and CSD17577Q5AT (Texas Instruments NexFET™ series) are active production devices with 30V Vdss and 60A continuous drain current (Ta). The on-resistance of 4.2 mOhm at 18A, 10V is superior to the AON6202. The 8-VSONP (5x6) package differs from the original 8-DFN footprint. Both variants are ROHS3 compliant. The CSD17577Q5AT variant is subject to REACH regulations, while CSD17577Q5A is REACH Unaffected.

STL66N3LLH5 (STMicroelectronics STripFET™ V series) is an active production device with 30V Vdss and 80A continuous drain current (Tc). The on-resistance of 5.8 mOhm at 10.5A, 10V is comparable to the AON6202. The PowerFlat™ (5x6) package differs from the original 8-DFN footprint. The device is AEC-Q101 qualified and supports extended operating temperature to 175°C. ROHS3 compliance and active product status ensure availability.

STL90N3LLH6 (STMicroelectronics DeepGATE™/STripFET™ VI series) is an active production device with 30V Vdss and 90A continuous drain current (Tc). The on-resistance of 4.5 mOhm at 12A, 10V is superior to the AON6202. The PowerFlat™ (5x6) package differs from the original 8-DFN footprint. ROHS3 compliance and active product status support long-term availability.

Tier 3 - Specialized Applications:

DMT3006LFG-13 (Diodes Incorporated) is an active production device with 30V Vdss, 16A (Ta) and 55.6A (Tc) continuous drain current. The device is AEC-Q101 qualified for automotive applications. The PowerDI3333-8 package differs from the original 8-DFN footprint. ROHS3 compliance is provided.

TPH6R003NL,LQ (Toshiba Semiconductor U-MOSVIII-H series) is an active production device with 30V Vdss and 38A continuous drain current (Tc). The on-resistance of 6 mOhm at 19A, 10V is comparable to the AON6202. The 8-SOP Advance (5x5) package differs from the original 8-DFN footprint. RoHS compliance is provided.

Package Compatibility Considerations:

The AON6202 uses an 8-DFN (5x6) package. Substitute devices employ alternative 8-pin surface mount packages including 8-VSONP, PG-TDSON-8-6, PowerFlat™, PowerDI3333-8, and 8-SOP Advance. While pinout compatibility may exist, PCB layout modifications are required for package transitions. Thermal performance characteristics differ across package types; verification of thermal requirements is necessary during design transition.

Frequently Asked Questions (FAQ)

Q: Can the AON6202 be directly replaced with the AON6558 without PCB modifications?

A: Yes. Both devices use the 8-DFN (5x6) package with identical footprints and pinouts. No PCB layout changes are required. However, the AON6558 is classified as Not For New Designs, limiting its use to legacy product support.

Q: What is the primary advantage of BSC0902NSATMA1 over the AON6202?

A: The BSC0902NSATMA1 offers significantly lower on-resistance (2.6 mOhm versus 5.5 mOhm at comparable conditions), resulting in reduced power dissipation and improved thermal performance. The device is in active production with ROHS3 compliance. The PG-TDSON-8-6 package requires PCB layout verification before implementation.

Q: Are the CSD17577Q5A and CSD17577Q5AT interchangeable?

A: Both devices are electrically identical with the same electrical specifications and 8-VSONP (5x6) package. The primary difference is packaging format: CSD17577Q5A is supplied in Tape & Reel (TR), while CSD17577Q5AT is supplied in Cut Tape (CT) & Digi-Reel®. REACH compliance status differs: CSD17577Q5A is REACH Unaffected, while CSD17577Q5AT is REACH Affected.

Q: Which substitute offers the best thermal performance?

A: STL90N3LLH6 provides the highest continuous drain current rating (90A Tc) with 60W power dissipation (Tc) and the lowest on-resistance (4.5 mOhm at 12A, 10V) among active production alternatives. The PowerFlat™ (5x6) package provides enhanced thermal characteristics compared to the original 8-DFN package.

Q: Is automotive qualification available in substitute devices?

A: Yes. DMT3006LFG-13 and STL66N3LLH5 are both AEC-Q101 qualified for automotive applications. These devices are suitable for automotive-grade designs requiring formal qualification documentation.

Q: What is the impact of package changes on circuit design?

A: Package transitions from 8-DFN to alternative 8-pin surface mount packages (8-VSONP, PG-TDSON-8-6, PowerFlat™, PowerDI3333-8, 8-SOP Advance) require PCB layout verification. Pinout compatibility must be confirmed, and thermal via placement may differ. Consult device datasheets for specific package dimensions and thermal characteristics before PCB redesign.

Q: Are all substitute devices RoHS compliant?

A: All substitute devices listed are RoHS compliant. AON6558, BSC0902NSATMA1, CSD17552Q5A, CSD17577Q5A, CSD17577Q5AT, DMT3006LFG-13, STL65N3LLH5, STL66N3LLH5, and STL90N3LLH6 are ROHS3 compliant. TPH6R003NL,LQ is RoHS compliant. The original AON6202 does not specify RoHS status.

Q: Which substitute is recommended for new product designs?

A: For new designs requiring active production status and long-term availability, BSC0902NSATMA1, CSD17577Q5A, STL66N3LLH5, STL90N3LLH6, DMT3006LFG-13, and TPH6R003NL,LQ are all suitable.

BSC0902NSATMA1 and STL90N3LLH6 offer superior on-resistance and thermal performance for power-sensitive applications.

Q: What is the difference between Ta and Tc current ratings?

A: Ta (ambient temperature) represents continuous drain current at 25°C ambient temperature with natural convection cooling. Tc (case temperature) represents continuous drain current at 25°C case temperature with enhanced thermal management. Tc ratings are typically higher due to improved heat dissipation. Application thermal design determines which rating applies.
