Parameter Comparison

Engineering Selection Recommendations

The OY393KE is the direct equivalent substitute for the obsolete OY393K. Both components are manufactured by Ohmite within the OY series and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY393K is obsolete while the OY393KE remains in active production.

The OY393KE provides an additional compliance advantage, meeting ROHS3 requirements compared to the non-compliant status of the original OY393K. Both components maintain REACH Unaffected status and EAR99 export classification. Selection of the OY393KE ensures design continuity with improved regulatory compliance and sustained component availability.

Frequently Asked Questions (FAQ)

Q: Can the OY393KE be used as a direct replacement for the OY393K?

A: Yes. The OY393KE provides complete electrical and mechanical equivalence to the OY393K across all specified parameters, including resistance value, tolerance, power rating, composition, package type, operating temperature range, and physical dimensions.

Q: What is the primary reason to substitute the OY393K?

A: The OY393K is classified as obsolete. The OY393KE, as an active production component from the same manufacturer and series, ensures ongoing availability and procurement continuity.

Q: Are there any compliance differences between these parts?

A: Yes. The OY393KE is ROHS3 compliant, while the OY393K is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 export classification.

Q: Do the physical dimensions match exactly?

A: Yes. Both the OY393K and OY393KE share identical dimensions of 0.276" Dia × 0.748" L (7.00mm × 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Are the electrical characteristics identical?

A: Yes. Both components provide 39 kOhms ±10% resistance at 2W power rating with ceramic composition, -1000/-1600 ppm/°C temperature coefficient, and -40°C to 220°C operating temperature range.
