Substitute Part Grouping Explanation

Substitution eligibility for the M2S025-1FCS325I is determined by strict equivalence across the following critical parameters:

• Identical ARM Cortex-M3 core processor architecture
• Matching 166MHz clock speed
• Equivalent 256KB flash and 64KB RAM configuration
• Identical 25K logic module FPGA capacity
• Same 325-FCBGA (11x11) package footprint and pinout
• Matching 180 I/O count
• Identical operating temperature range (-40°C to 100°C)
• Equivalent peripheral and connectivity feature set

The M2S025-FCSG325I meets all these criteria and qualifies as a parametric equivalent. The primary distinction between these parts lies in RoHS compliance status and inventory availability, not in electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the M2S025-1FCS325I and M2S025-FCSG325I are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and supply availability:

The M2S025-1FCS325I is suitable for applications where RoHS compliance is not a contractual requirement and existing designs are qualified to this part number.

The M2S025-FCSG325I is the appropriate choice for designs requiring ROHS3 compliance. This variant maintains full parametric equivalence while meeting current environmental and regulatory standards. Current inventory availability for M2S025-FCSG325I (15,100 units) significantly exceeds that of M2S025-1FCS325I (953 units), providing supply chain advantages.

Both parts share identical MSL ratings, REACH status, ECCN classification, and HTSUS codes, ensuring equivalent handling, storage, and regulatory treatment throughout the supply chain.

Frequently Asked Questions (FAQ)

Q: Are M2S025-1FCS325I and M2S025-FCSG325I pin-for-pin compatible?

A: Yes. Both parts use the identical 325-FCBGA (11x11) package with 180 I/O pins in the same configuration. PCB layouts and footprints are directly interchangeable.

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

A: The primary difference is RoHS compliance status. M2S025-1FCS325I is RoHS non-compliant, while M2S025-FCSG325I is ROHS3 compliant. All electrical specifications, memory configurations, processor speed, and peripheral features are identical.

Q: Can I substitute M2S025-FCSG325I for M2S025-1FCS325I in existing designs?

A: Yes, from an electrical and mechanical standpoint. However, design qualification and compliance documentation should be reviewed to ensure the ROHS3-compliant variant meets your production requirements.

Q: Are there any performance differences between these parts?

A: No. Both parts operate at 166MHz with identical ARM Cortex-M3 core architecture, 256KB flash, 64KB RAM, and 25K FPGA logic modules. Performance characteristics are equivalent.

Q: What is the MSL rating for both parts?

A: Both parts carry an MSL rating of 3 with a 168-hour floor life. Identical moisture sensitivity handling and storage requirements apply to both variants.

Q: Which part should I specify for new designs?

A: Selection depends on your compliance requirements. For designs requiring ROHS3 compliance, specify M2S025-FCSG325I. For applications without RoHS requirements, either part is suitable based on availability and existing qualification status.
