The OX103KE meets all specified electrical and mechanical parameters, establishing it as a direct equivalent to the OX103K.

Parameter Comparison

Engineering Selection Recommendations

The OX103KE is the direct equivalent substitute for the OX103K. Both components share identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction is product status: the OX103K is obsolete while the OX103KE maintains active production status. Additionally, the OX103KE achieves ROHS3 compliance, whereas the OX103K is non-compliant with RoHS directives. For new designs and ongoing system support where regulatory compliance is required, the OX103KE is the appropriate selection. Both components maintain equivalent REACH status and ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the OX103KE be used as a direct replacement for the OX103K in existing applications?

A: Yes. The OX103KE provides complete electrical and mechanical equivalence to the OX103K. All specified parameters—resistance, tolerance, power rating, temperature range, and physical dimensions—are identical between the two components.

Q: What is the significance of the product status difference between OX103K and OX103KE?

A: The OX103K is classified as obsolete, indicating discontinued production. The OX103KE maintains active production status, ensuring long-term availability for component procurement and system support.

Q: Does the RoHS compliance difference affect substitution compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. However, for applications subject to RoHS directives or regulatory requirements, the ROHS3-compliant OX103KE is the required selection.

Q: Are the physical dimensions identical between OX103K and OX103KE?

A: Yes. Both components share identical dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What packaging options are available for the OX103KE?

A: The OX103KE is supplied in bulk packaging, whereas the OX103K packaging specification was not provided in the available data.
