Substitute Part Grouping Explanation

Substitution eligibility for the M2S090T-FGG484I is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters: All substitute parts must maintain identical processor architecture (ARM Cortex-M3), clock speed (166MHz), FPGA logic module count (90K), memory configuration (512KB flash, 64KB RAM), and I/O count (267 pins).

Package Compatibility: All substitutes use the 484-FPBGA (23x23) package format with identical pin assignments and mechanical dimensions.

Peripheral and Connectivity Support: All substitutes provide equivalent DDR, PCIe, and SERDES peripheral support with identical CANbus, Ethernet, I2C, SPI, UART/USART, and USB connectivity options.

Environmental Specifications: All substitutes operate across the identical temperature range (-40°C to 100°C junction temperature) and share the same MSL rating (3, 168 hours).

The identified substitutes differ only in packaging format (Tray vs. standard packaging) and regulatory compliance status (RoHS3 compliant vs. non-compliant, ECCN classification variations). These differences do not affect functional or electrical compatibility.

Engineering Selection Recommendations

All four parts are functionally equivalent and electrically interchangeable based on identical core specifications, memory configuration, and peripheral support. Selection between these parts should be based on regulatory and compliance requirements specific to the application and target market.

For RoHS3 Compliant Applications: M2S090T-FGG484I, M2S090-FGG484I, and M2S090TS-1FGG484I are suitable. These parts meet ROHS3 compliance requirements and carry ECCN classification 3A991D.

For Non-Compliant or Legacy Applications: M2S090TS-1FG484I is available as an alternative, though it carries RoHS non-compliant status and ECCN classification 5A002A1.

For Packaging Considerations: M2S090T-FGG484I is supplied in standard packaging, while M2S090-FGG484I, M2S090TS-1FG484I, and M2S090TS-1FGG484I are supplied in Tray packaging. Packaging format does not affect electrical performance or pin compatibility.

Frequently Asked Questions (FAQ)

Q: Are all listed parts pin-compatible with the M2S090T-FGG484I?

A: Yes. All substitute parts use the identical 484-FPBGA (23x23) package with 267 I/O pins in the same configuration. Direct socket substitution is supported without PCB redesign.

Q: What is the difference between M2S090T-FGG484I and M2S090-FGG484I?

A: These parts are electrically and functionally identical. The primary difference is packaging format: M2S090T-FGG484I uses standard packaging while M2S090-FGG484I uses Tray packaging. Both maintain ROHS3 compliance and identical ECCN classification.

Q: Can M2S090TS-1FG484I be used in applications requiring RoHS3 compliance?

A: No. M2S090TS-1FG484I is RoHS non-compliant and carries a different ECCN classification (5A002A1). Applications with RoHS3 requirements must use M2S090T-FGG484I, M2S090-FGG484I, or M2S090TS-1FGG484I.

Q: Do the ECCN differences affect functional compatibility?

A: No. ECCN classification differences reflect regulatory and export control status only. Functional, electrical, and mechanical compatibility remains identical across all parts.

Q: What is the significance of the MSL rating for these parts?

A: All parts share MSL rating 3 (168 hours), indicating identical moisture sensitivity and requiring equivalent handling, storage, and reflow procedures during assembly.

Q: Are there any performance differences between substitute parts?

A: No. All parts operate at 166MHz with identical processor architecture, memory configuration, FPGA logic module count, and peripheral support. Performance is equivalent across all substitutes.
