OY152KE Equivalent & Substitute Parts

Part Overview

The OY152KE is a 1.5 kOhms ±10% 2W through-hole resistor manufactured by Ohmite in the OY series. This ceramic axial resistor features moisture resistance and pulse withstanding capability, designed for applications requiring reliable performance across a wide operating temperature range from -40°C to 220°C. The part is currently active in production with 1021 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to availability constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OY152KE is determined by the following critical parameters:

• Resistance Value: Must be 1.5 kOhms ±10%
• Composition: Ceramic construction required
• Package Type: Axial through-hole configuration
• Tolerance: ±10% tolerance class
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The OC2K152E-TR qualifies as a manufacturer-recommended substitute based on matching resistance, tolerance, composition, and package specifications. While the OC2K152E-TR has a lower power rating (1.7W versus 2W) and different temperature coefficient characteristics, it maintains electrical and mechanical compatibility for applications within its rated power envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the OY152KE and OC2K152E-TR are active production parts with full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on power dissipation requirements: the OY152KE is suitable for applications requiring the full 2W rating, while the OC2K152E-TR is appropriate for circuits operating within its 1.7W envelope. The OC2K152E-TR offers an extended lower operating temperature limit (-55°C versus -40°C), which may be advantageous for applications in extreme cold environments. Physical dimensions differ slightly; verify PCB layout compatibility before substitution, particularly regarding hole spacing and component clearance in confined layouts.

Frequently Asked Questions (FAQ)

Q: Can the OC2K152E-TR replace the OY152KE in all applications?

A: The OC2K152E-TR is electrically compatible for resistance and tolerance specifications. However, substitution is limited to applications where power dissipation does not exceed 1.7W. If your circuit requires the full 2W rating, the OY152KE is the appropriate choice.

Q: What are the physical differences between these parts?

A: The OC2K152E-TR has a slightly larger diameter (0.311" versus 0.276") and marginally longer length (0.752" versus 0.748"). These dimensional differences are minor but should be verified against PCB layout constraints, particularly in high-density designs.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the OY152KE and OC2K152E-TR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference in temperature coefficient between these parts?

A: The OY152KE has a temperature coefficient of -1000/-1600 ppm/°C, while the OC2K152E-TR has 0/-800 ppm/°C. The OC2K152E-TR exhibits lower temperature-dependent resistance variation, which may be beneficial for precision applications sensitive to thermal drift.

Q: Which part should I select for new designs?

A: For new designs, select based on power budget requirements. If power dissipation is ≤1.7W, either part is acceptable; the OC2K152E-TR offers extended temperature range and lower thermal coefficient. If power dissipation exceeds 1.7W, the OY152KE is required.
