Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST4SI2M0004TPIFW is determined by alignment across the following critical parameters:

Base Product Family: Both the main part and substitute share the ST4SI2 base product number, confirming they belong to the same eSIM System-on-Chip product line from STMicroelectronics.

Processor Architecture: The Arm® SecurCore® SC300™ RISC processor is the core computational element and must remain consistent across substitutions.

Network Technology Support: The substitute part must support the same cellular network technologies (2G, 3G, 4G LTE IoT) to ensure functional compatibility in M2M industrial applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting the same environmental and regulatory requirements.

Electrical Classification: Voltage class compatibility (5V, 3V, 1.8V) ensures the substitute operates within the same power supply specifications.

Operating Temperature Range: The -40°C ~ 105°C operating range defines the thermal envelope for industrial deployment.

Physical Form Factor: The 5mm x 6mm x 1mm dimensions and eSIM (MFF2) format establish the mechanical compatibility baseline.

The substitute part ST4SI2M0020TPIFW maintains these core parameters while transitioning from obsolete to active product status, enabling continued component sourcing and design support.

Parameter Comparison

Engineering Selection Recommendations

Product Status Transition: The ST4SI2M0004TPIFW is classified as obsolete, while the ST4SI2M0020TPIFW maintains active product status. This transition ensures continued manufacturing support, technical documentation availability, and long-term supply chain reliability.

Regulatory Compliance Alignment: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, confirming they satisfy the same environmental and regulatory requirements for industrial M2M applications.
