Substitute Part Grouping Explanation

Substitution of the OY824K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY824KE maintains identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, operating temperature range, and temperature coefficient. Both components feature identical moisture resistance and pulse withstanding characteristics, and share the same physical dimensions, ensuring direct mechanical and electrical compatibility. The primary distinction between these parts is product status and RoHS compliance level.

Parameter Comparison

Engineering Selection Recommendations

The OY824KE serves as the direct equivalent substitute for the obsolete OY824K. Both components are manufactured by Ohmite and provide identical electrical performance and mechanical compatibility. The OY824KE is classified as active product status, ensuring continued availability and supply chain reliability. For applications requiring RoHS3 compliance, the OY824KE is the appropriate selection. For legacy systems or applications where RoHS compliance is not mandated, either part may be selected based on availability and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can OY824KE be used as a direct replacement for OY824K in existing designs?

A: Yes. The OY824KE provides identical electrical specifications, including 820 kOhms resistance, ±10% tolerance, 2W power rating, and ceramic composition. Physical dimensions and operating temperature range are equivalent, enabling direct substitution without circuit redesign.

Q: What is the primary difference between OY824K and OY824KE?

A: The OY824K is classified as obsolete, while OY824KE is active product status. Additionally, OY824KE is ROHS3 compliant, whereas OY824K is RoHS non-compliant. All electrical and mechanical parameters remain identical.

Q: Are the axial package dimensions identical between both parts?

A: Yes. Both OY824K and OY824KE share identical physical dimensions of 0.276" diameter by 0.748" length (7.00mm × 19.00mm), ensuring compatibility with existing PCB layouts and through-hole mounting configurations.

Q: Does the temperature coefficient differ between these resistors?

A: No. Both components maintain the same temperature coefficient specification of -1000/-1600 ppm/°C and operate across the identical temperature range of -40°C to 220°C.

Q: Which part should be selected for new production designs?

A: OY824KE is the appropriate selection for new production designs due to active product status and ROHS3 compliance, ensuring long-term supply chain availability and regulatory alignment.
