Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY152K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical resistance value (1.5 kOhms), tolerance (±10%), power rating (2W), composition (ceramic), axial package configuration, operating temperature range (-40°C to 220°C), and physical dimensions (0.276" Dia × 0.748" L). The OY152KE qualifies as a direct substitute because it matches all these parameters exactly while offering the advantage of active product status and improved compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The OY152KE is the direct equivalent for the obsolete OY152K. Both parts are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY152K is obsolete while the OY152KE maintains active production status, ensuring long-term availability and supply chain continuity. Additionally, the OY152KE achieves ROHS3 compliance, whereas the OY152K is RoHS non-compliant. For new designs or component replenishment, the OY152KE is the appropriate selection. Both parts maintain equivalent REACH and ECCN classifications, confirming regulatory alignment across the substitution.

Frequently Asked Questions (FAQ)

Q: Can the OY152KE be used as a direct replacement for the OY152K in existing designs?

A: Yes. The OY152KE is electrically and mechanically identical to the OY152K. All critical parameters—resistance, tolerance, power rating, temperature range, and physical dimensions—are equivalent. The parts are pin-compatible and functionally interchangeable.

Q: Why is the OY152K listed as obsolete?

A: The OY152K has been discontinued by Ohmite. The OY152KE represents the active production equivalent within the same OY series, ensuring continued availability of this specification.

Q: What is the difference in packaging between OY152K and OY152KE?

A: Both parts use identical axial through-hole packaging with the same physical dimensions (0.276" Dia × 0.748" L). The OY152K was supplied in standard packaging, while the OY152KE is available in bulk packaging. This distinction does not affect electrical or mechanical compatibility.

Q: Are there compliance differences between these parts?

A: The OY152KE is ROHS3 compliant, while the OY152K is RoHS non-compliant. Both maintain REACH Unaffected status and share the same ECCN (EAR99) and HTSUS classifications. For applications requiring RoHS compliance, the OY152KE is the appropriate choice.

Q: What is the temperature coefficient specification, and does it affect substitution?

A: Both parts specify a temperature coefficient of -1000/-1600 ppm/°C, indicating resistance change over the operating temperature range of -40°C to 220°C. This parameter is identical across both parts, confirming thermal performance equivalence.

Q: Can these axial resistors be used in surface-mount applications?

A: No. Both the OY152K and OY152KE are through-hole axial components designed for insertion into PCB holes. They are not suitable for surface-mount assembly without mechanical adaptation.
