Substitute Part Grouping Explanation

Substitution eligibility for the M2S005S-1FG484 is determined by strict equivalence across the following parameters:

• Core processor architecture and speed (ARM Cortex-M3 at 166MHz)
• Memory configuration (128KB flash, 64KB RAM)
• FPGA fabric capacity (5K logic modules)
• Package specification (484-FPBGA with 23x23 footprint and 209 I/O pins)
• Peripheral and connectivity feature set (CANbus, Ethernet, I2C, SPI, UART/USART, USB, DDR)
• Operating temperature range (0°C to 85°C)
• Series classification (SmartFusion2)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in RoHS compliance status, MSL rating, or inventory availability do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both M2S005S-1FG484 and M2S005-FGG484 are functionally equivalent and directly interchangeable at the circuit level. Selection between these parts should be based on regulatory and compliance requirements:

The M2S005-FGG484 is ROHS3 compliant and is the preferred choice for applications subject to RoHS directives or customer specifications requiring RoHS compliance. The M2S005S-1FG484, while RoHS non-compliant, remains suitable for applications without RoHS requirements. Both parts share identical electrical specifications, thermal characteristics, and package dimensions, ensuring seamless substitution without design modifications.

Frequently Asked Questions (FAQ)

Q: Are M2S005S-1FG484 and M2S005-FGG484 pin-compatible?

A: Yes. Both parts use the 484-FPBGA (23x23) package with 209 I/O pins in identical pinout configuration. Direct PCB substitution is possible without layout changes.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. M2S005-FGG484 is ROHS3 compliant, while M2S005S-1FG484 is RoHS non-compliant. All electrical, thermal, and functional parameters are identical.

Q: Can I use M2S005-FGG484 as a drop-in replacement for M2S005S-1FG484?

A: Yes, M2S005-FGG484 is a direct functional equivalent and can be used as a drop-in replacement without any circuit or firmware modifications.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate at 166MHz, support identical memory configurations (128KB flash, 64KB RAM), and share the same operating temperature range of 0°C to 85°C (TJ).

Q: Which part should I specify for new designs?

A: For new designs subject to RoHS regulations or customer RoHS requirements, specify M2S005-FGG484. For applications without RoHS mandates, either part is acceptable based on availability and cost considerations.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both M2S005S-1FG484 and M2S005-FGG484 have MSL rating of 3 with a 168-hour floor life requirement.
