Engineering Selection Recommendations

The EKXG351ELL151MMP1S is the direct equivalent substitute for the obsolete KXG350VB151M18X35LL. Selection of this substitute is based on the following engineering factors:

Product Status: The main part is classified as obsolete, while the substitute is active. This transition ensures continued availability and supply chain reliability for new production and field replacements.

Compliance Status: The substitute part is ROHS3 compliant, whereas the main part is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in regulated markets and applications.

Electrical and Mechanical Equivalence: All critical parameters—capacitance, voltage rating, tolerance, thermal lifetime, operating temperature range, ripple current specifications, and physical dimensions—are identical between the main part and substitute. This ensures direct functional compatibility without circuit redesign or PCB layout modification.

Regulatory Alignment: Both parts maintain identical REACH and ECCN classifications, confirming regulatory consistency for export and supply chain purposes.

The substitute part is suitable for direct replacement in all applications where the KXG350VB151M18X35LL was originally specified.

Frequently Asked Questions (FAQ)
