Substitute Part Grouping Explanation

Substitution eligibility for the M2S050-FG484 is determined by strict equivalence across the following critical parameters:

• Processor Architecture: ARM Cortex-M3 core
• Operating Frequency: 166MHz
• Memory Configuration: 256KB flash, 64KB RAM
• FPGA Capacity: 50K logic modules
• Package Specification: 484-FPBGA (23x23) form factor
• I/O Count: 267 pins
• Peripheral Set: DDR, PCIe, SERDES support
• Connectivity Interfaces: CANbus, Ethernet, I2C, SPI, UART/USART, USB
• Temperature Rating: 0°C to 85°C (TJ)
• Moisture Sensitivity: MSL 3 (168 Hours)

The M2S050-FGG484 qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, memory configuration, FPGA capacity, package geometry, and functional capabilities. The primary distinction lies in RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

M2S050-FG484 is suitable for applications where RoHS non-compliant components are acceptable or where legacy system compatibility is required. This part maintains active product status and is available in inventory.

M2S050-FGG484 is the preferred selection for new designs and applications subject to RoHS3 compliance requirements. This variant maintains identical electrical and functional specifications while meeting current environmental and material restriction directives. The M2S050-FGG484 also offers higher inventory availability (1058 units versus 749 units).

Both parts are functionally interchangeable at the electrical and mechanical level. Selection between them should be based on compliance requirements and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are M2S050-FG484 and M2S050-FGG484 pin-compatible?

A: Yes. Both parts use the 484-FPBGA (23x23) package with 267 I/O pins in identical pin configurations. PCB layouts and socket designs are directly interchangeable.

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

A: The primary difference is RoHS compliance status. M2S050-FGG484 is ROHS3 compliant, while M2S050-FG484 is RoHS non-compliant. All electrical specifications, memory configuration, FPGA capacity, and functional capabilities are identical.

Q: Can I substitute M2S050-FGG484 for M2S050-FG484 in existing designs?

A: Yes. The M2S050-FGG484 is a direct functional equivalent with no changes required to firmware, PCB layout, or system integration. The substitution is electrically and mechanically transparent.

Q: Which part should I specify for new product designs?

A: M2S050-FGG484 is recommended for new designs due to ROHS3 compliance alignment with current environmental regulations and higher inventory availability.

Q: Are there any firmware or software compatibility issues between these parts?

A: No. Both parts execute identical instruction sets and support the same peripheral interfaces, connectivity protocols, and development tools. Firmware compiled for one part runs without modification on the other.

Q: What is the moisture sensitivity level for both parts?

A: Both M2S050-FG484 and M2S050-FGG484 have MSL 3 rating with a 168-hour floor life. Identical moisture handling and storage procedures apply to both variants.
