Parameter Comparison

Engineering Selection Recommendations

The OY182KE is the direct equivalent for the obsolete OY182K. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the OY182K is obsolete and RoHS non-compliant, while the OY182KE is active and ROHS3 compliant. For new designs and ongoing procurement, the OY182KE is the appropriate selection. Both parts carry identical REACH and ECCN classifications, ensuring consistent regulatory treatment in supply chain applications.

Frequently Asked Questions (FAQ)

Q: Can the OY182KE be used as a direct replacement for the OY182K?
