Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY184K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY184KE maintains identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, physical dimensions, operating temperature range, and temperature coefficient. Both parts feature identical moisture resistance and pulse withstanding characteristics. The substitution is valid because all functional and mechanical parameters remain unchanged between the main part and the substitute.

Parameter Comparison

Engineering Selection Recommendations

The OY184KE serves as the direct substitute for the obsolete OY184K. Both parts are manufactured by Ohmite and maintain complete electrical and mechanical equivalence. The primary distinction is product status: the OY184K is obsolete while the OY184KE is active and available for procurement. Additionally, the OY184KE achieves ROHS3 compliance, whereas the OY184K is RoHS non-compliant. For new designs and ongoing production requiring this 180 kOhms 2W axial resistor specification, the OY184KE is the appropriate selection. Both parts share identical performance characteristics across all operating parameters, physical dimensions, and functional features.

Frequently Asked Questions (FAQ)

Q: Can OY184KE be used as a direct replacement for OY184K in existing assemblies?

A: Yes. The OY184KE is electrically and mechanically identical to the OY184K. All critical parameters including resistance value, tolerance, power rating, package dimensions, and operating temperature range are equivalent. Direct substitution is valid for circuit applications.

Q: What is the primary reason for substituting OY184K with OY184KE?

A: The OY184K is classified as obsolete, making it unavailable for new procurement. The OY184KE is an active product from the same manufacturer with identical specifications, ensuring continued availability and supply chain continuity.

Q: Are there any compliance differences between OY184K and OY184KE?

A: Yes. The OY184KE is ROHS3 compliant, while the OY184K is RoHS non-compliant. For applications subject to RoHS regulations, the OY184KE is the required choice.

Q: Do the physical dimensions of OY184KE match OY184K?

A: Yes. Both parts have 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: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts maintain 180 kOhms resistance with ±10% tolerance, 2W power rating, identical temperature coefficient of -1000/-1600 ppm/°C, and operating temperature range of -40°C to 220°C. Moisture resistance and pulse withstanding features are equivalent.
