Substitute Part Grouping Explanation

Substitution eligibility for the M2S050-1FCS325I is determined by strict equivalence across the following critical parameters:

• Identical core processor architecture (ARM Cortex-M3)
• Matching clock speed (166MHz)
• Equivalent memory configuration (256KB flash, 64KB RAM)
• Same FPGA capacity (50K logic modules)
• Identical package type and pin count (325-FCBGA, 11x11, 200 I/O)
• Matching connectivity interfaces (CANbus, Ethernet, I2C, SPI, UART/USART, USB)
• Equivalent peripheral support (DDR, PCIe, SERDES)
• Same operating temperature range (-40°C to 100°C)

The M2S050-FCSG325I meets all these criteria and qualifies as a parametric equivalent. The primary distinction between these parts lies in RoHS compliance status and packaging designation, not in functional or electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The M2S050-FCSG325I serves as a direct parametric equivalent to the M2S050-1FCS325I for applications where all electrical and functional specifications are identical. Selection between these parts should be based on compliance requirements and regulatory constraints applicable to the end application.

For designs requiring RoHS3 compliance, the M2S050-FCSG325I is the appropriate choice. For applications without RoHS compliance mandates, either part satisfies the functional requirements. Both parts maintain identical REACH status and export classification codes, ensuring equivalent regulatory standing in international supply chains.

Frequently Asked Questions (FAQ)

Q: Are M2S050-1FCS325I and M2S050-FCSG325I electrically interchangeable?

A: Yes. Both parts share identical core processor architecture, clock speed, memory configuration, FPGA capacity, package type, pin count, and I/O specifications. No circuit modifications are required for substitution.

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

A: The primary difference is RoHS compliance status. The M2S050-FCSG325I is RoHS3 compliant, while the M2S050-1FCS325I is RoHS non-compliant. All other electrical and mechanical specifications are identical.

Q: Can I use M2S050-FCSG325I as a drop-in replacement for M2S050-1FCS325I?

A: Yes, provided your application does not have specific requirements tied to the RoHS non-compliant status of the original part. The 325-FCBGA package, pin configuration, and electrical characteristics are identical.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts have Moisture Sensitivity Level 3 with a 168-hour floor life specification. Identical handling and storage protocols apply to both.

Q: Are there any differences in operating temperature range?

A: No. Both parts operate across the identical temperature range of -40°C to 100°C (junction temperature).

Q: What connectivity interfaces are supported by both parts?

A: Both parts support CANbus, Ethernet, I2C, SPI, UART/USART, and USB interfaces, with equivalent DDR, PCIe, and SERDES peripheral support.
