Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY123K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY123KE maintains identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, operating temperature range, and temperature coefficient. Both components are manufactured by Ohmite within the same OY series, ensuring mechanical and electrical compatibility. The substitution is valid based on matching all provided technical parameters without deviation.

Parameter Comparison

Engineering Selection Recommendations

The OY123KE serves as the direct substitute for the obsolete OY123K. Selection of OY123KE is supported by its active product status, ensuring long-term availability and supply chain continuity. The OY123KE achieves RoHS3 compliance, whereas the OY123K is non-compliant, making OY123KE the preferred choice for applications subject to RoHS requirements. Both components maintain identical electrical and mechanical specifications, supporting direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can OY123KE replace OY123K in existing designs? A: Yes. OY123KE is electrically and mechanically equivalent to OY123K across all specified parameters, including resistance, tolerance, power rating, package dimensions, and operating temperature range.

Q: What is the primary reason to substitute OY123K? A: OY123K carries obsolete product status. OY123KE, with active status, provides continued availability and supply security.

Q: Are there compliance differences between OY123K and OY123KE? A: OY123KE is RoHS3 compliant, while OY123K is non-compliant. For applications requiring RoHS compliance, OY123KE is the appropriate selection.

Q: Do the axial package dimensions differ between these parts? A: No. Both components share identical dimensions of 0.276" diameter by 0.748" length (7.00mm x 19.00mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Are the electrical characteristics identical? A: Yes. Resistance value (12 kOhms), tolerance (±10%), power rating (2W), temperature coefficient (-1000/-1600 ppm/°C), and operating temperature range (-40°C to 220°C) are identical between OY123K and OY123KE.
