Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2S025T-VF400 is determined by strict equivalence across the following critical parameters:

Processor Architecture and Performance: The core processor must be ARM Cortex-M3 operating at 166MHz to ensure software compatibility and performance parity.

Memory Configuration: Flash memory must be 256KB and RAM must be 64KB. These specifications directly impact firmware capacity and runtime performance.

FPGA Fabric: The FPGA logic module count must be 25K to maintain functional equivalence in hardware acceleration capabilities.

Package and Pin Configuration: The 400-pin VFBGA (17x17) package with 207 I/O pins must be identical to ensure mechanical and electrical compatibility with existing PCB designs.

Thermal and Environmental Specifications: Operating temperature range of 0°C to 85°C and MSL rating of 3 must be maintained.

Manufacturer: All substitutes must be from Microchip Technology to ensure consistency in design support, documentation, and supply chain management.

The M2S025-VFG400 meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the M2S025T-VF400 and M2S025-VFG400 are functionally equivalent and interchangeable at the component level based on electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status.

The M2S025-VFG400 carries ROHS3 compliance certification, making it the preferred selection for applications subject to RoHS directives or customer requirements mandating lead-free manufacturing processes. The M2S025T-VF400 is RoHS non-compliant and should be selected only when legacy designs or specific procurement constraints require non-compliant components.

Both parts maintain identical product status (Active), REACH unaffected status, and ECCN/HTSUS classifications. Selection between these substitutes should be driven by regulatory requirements, supply chain availability, and project-specific compliance mandates rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can M2S025-VFG400 be used as a direct replacement for M2S025T-VF400 in existing designs?

A: Yes. The M2S025-VFG400 is a parametric equivalent with identical electrical specifications, processor architecture, memory configuration, FPGA fabric, package type, and I/O pin count. No PCB redesign or firmware modification is required for substitution.

Q: What is the difference between M2S025T-VF400 and M2S025-VFG400?

A: The primary difference is RoHS compliance status. M2S025-VFG400 is ROHS3 compliant, while M2S025T-VF400 is RoHS non-compliant. All other specifications including processor, memory, FPGA configuration, and package are identical.

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

A: No. Both parts operate at 166MHz with identical operating temperature ranges (0°C to 85°C junction temperature) and thermal characteristics. Performance and thermal behavior are equivalent.

Q: Which part should be selected for new designs?

A: M2S025-VFG400 is recommended for new designs due to ROHS3 compliance, which aligns with current regulatory standards and customer expectations. M2S025T-VF400 should only be selected if legacy design constraints or specific procurement requirements mandate non-compliant components.

Q: Is the 400-VFBGA package identical between both parts?

A: Yes. Both parts use the 400-pin VFBGA (17x17) package with 207 I/O pins. Package dimensions, pin assignments, and mechanical specifications are identical, ensuring direct PCB compatibility.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically equivalent with identical electrical and mechanical specifications, they can be used interchangeably within the same design and production batch. However, compliance documentation should reflect the specific part number used in each unit.
