Substitute Part Grouping Explanation

Substitution of PS2501L-1-E3-K-A with PS2501L-1-F3-K-A is permissible based on functional equivalence across all critical electrical and mechanical parameters. Both components share the same base product number (PS2501) and are qualified within the NEPOC series. The key substitution parameters—isolation voltage, channel count, output type, current transfer ratio range, maximum output voltage, output current rating, saturation voltage, rise/fall time characteristics, operating temperature range, and surface-mount 4-SMD package configuration—are identical between the main part and substitute. The primary distinction is product status: the main part PS2501L-1-E3-K-A is obsolete while PS2501L-1-F3-K-A maintains active status through Renesas Electronics Corporation, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

For new designs or redesigns, PS2501L-1-F3-K-A is the preferred selection due to active product status and ROHS3 compliance. The substitute part maintains full electrical and mechanical compatibility with the obsolete main part across all specified parameters. The REACH unaffected status of PS2501L-1-F3-K-A further supports selection for applications subject to regulatory compliance requirements. Both components function identically within the specified electrical operating window, with no design modifications required for PCB layout or electrical interface implementation.
