Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5CSX-H5-4YA-RC is determined by strict equivalence across the following parameters:

Critical Parameters (Must Match Exactly):

• Core processor architecture and FPGA variant (ARM Cortex-A9, Cyclone V SX/SE)
• Operating frequency (800MHz)
• RAM capacity (1GB)
• Physical connector type and form factor (Edge Connector, 82.00mm x 39.00mm)
• Operating temperature range (0°C ~ 70°C)

Functional Parameters (Allowable Variation):

• Flash memory size may vary within the MitySOM product line, provided the substitute meets or exceeds the minimum storage requirements for the target application

The identified substitute part 5CSE-H4-3YA-RC maintains equivalence across all critical parameters while differing only in flash memory capacity (16MB versus 32MB).

Parameter Comparison

Engineering Selection Recommendations

Both the 5CSX-H5-4YA-RC and 5CSE-H4-3YA-RC are active production parts from Critical Link LLC with RoHS compliance certification. Selection between these parts depends solely on flash memory requirements:

• 5CSX-H5-4YA-RC is specified when 32MB flash storage is required for firmware, bootloader, or application code.
• 5CSE-H4-3YA-RC is suitable for applications where 16MB flash capacity is sufficient, offering equivalent processor performance, RAM capacity, and physical compatibility.

Both modules maintain identical operating temperature ranges, connector specifications, and regulatory compliance status. The choice between these parts is determined by application-specific flash memory storage needs only.

Frequently Asked Questions (FAQ)

Q: Can the 5CSE-H4-3YA-RC substitute for the 5CSX-H5-4YA-RC in existing designs?

A: Yes, provided the application does not require more than 16MB of flash storage. All other electrical and mechanical parameters are identical, including processor speed, RAM capacity, connector type, and physical dimensions.

Q: Are there any differences in processor performance between these two modules?

A: No. Both modules use the same ARM Cortex-A9 processor running at 800MHz with identical NEON SIMD co-processor support and 1GB RAM configuration.

Q: Do both parts fit the same PCB footprint and connector?

A: Yes. Both modules use edge connectors and share identical physical dimensions of 3.200" L x 1.500" W (82.00mm x 39.00mm).

Q: What is the primary difference between these substitute parts?

A: The only difference is flash memory capacity: the 5CSX-H5-4YA-RC provides 32MB while the 5CSE-H4-3YA-RC provides 16MB.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5CSX-H5-4YA-RC and 5CSE-H4-3YA-RC are RoHS compliant and suitable for applications with regulatory compliance requirements.

Q: What operating temperature range do these modules support?

A: Both modules operate across the identical temperature range of 0°C to 70°C.
