Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY103K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY103KE maintains identical specifications for resistance value, tolerance, power rating, composition, package configuration, physical dimensions, operating temperature range, and temperature coefficient. Both components are manufactured by Ohmite within the OY series and feature identical moisture resistance and pulse withstanding characteristics. The primary distinction between the OY103K and OY103KE is product status and RoHS compliance level, with OY103KE representing the active production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OY103KE is the direct functional equivalent of the OY103K and serves as the primary substitute for obsolete unit replacement and new design implementations. Both components are electrically and mechanically identical across all specified parameters. The OY103KE maintains active production status and achieves ROHS3 compliance, providing advantages for applications subject to regulatory requirements. Selection between these components should be based on procurement availability, compliance mandates, and system-level RoHS requirements. The OY103KE is suitable for direct substitution in all applications previously utilizing the OY103K.

Frequently Asked Questions (FAQ)

Q: Can OY103KE be used as a direct replacement for OY103K? A: Yes. The OY103KE is electrically and mechanically equivalent to the OY103K across all specified parameters, including resistance, tolerance, power rating, physical dimensions, and operating temperature range.

Q: What is the primary difference between OY103K and OY103KE? A: The OY103K is classified as obsolete, while OY103KE is in active production. Additionally, OY103KE achieves ROHS3 compliance, whereas OY103K is RoHS non-compliant.

Q: Are the physical dimensions identical between OY103K and OY103KE? A: Yes. Both components share identical axial package dimensions of 0.276" diameter by 0.748" length (7.00mm x 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Do both components operate across the same temperature range? A: Yes. Both OY103K and OY103KE operate from -40°C to 220°C with identical temperature coefficients of -1000 / -1600 ppm/°C.

Q: Is RoHS compliance a factor in selecting between these components? A: RoHS compliance becomes relevant only if your application or regulatory environment mandates it. OY103KE provides ROHS3 compliance, while OY103K does not. For applications without RoHS requirements, both components are functionally equivalent.
