OY150K Equivalent & Substitute Parts

Part Overview

The OY150K is a 15 Ohms ±10% 2W through-hole resistor with axial leads, manufactured by Ohmite. This ceramic composition resistor features moisture resistance and pulse withstanding capabilities, designed for applications requiring reliable performance across a wide operating temperature range of -40°C to 220°C. The OY150K is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY150K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 15 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY150KE meets all these parameters and is classified as an active product, providing continuity for applications currently using the obsolete OY150K.

Engineering Selection Recommendations

The OY150KE is the direct substitute for the obsolete OY150K. Both components are manufactured by Ohmite within the OY series and maintain identical electrical specifications and physical dimensions. The OY150KE offers the advantage of active product status, ensuring continued availability and supply chain reliability.

A significant distinction exists in regulatory compliance: the OY150K is RoHS non-compliant, while the OY150KE achieves ROHS3 compliance. For applications subject to RoHS requirements or environmental regulations, the OY150KE is the appropriate selection. For legacy systems or applications without RoHS mandates, both components are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the OY150KE directly replace the OY150K in existing designs?

A: Yes. The OY150KE is electrically and mechanically identical to the OY150K. Both components share the same resistance value, tolerance, power rating, physical dimensions, and operating temperature range. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from OY150K to OY150KE?

A: The OY150K is classified as obsolete, creating supply and long-term availability concerns. The OY150KE is an active product from the same manufacturer and series, providing assured procurement and support. Additionally, the OY150KE meets ROHS3 compliance requirements.

Q: Are there any packaging differences between OY150K and OY150KE?

A: The OY150K is supplied in standard packaging, while the OY150KE is supplied in bulk packaging. Both maintain identical component specifications and axial lead configuration. Packaging format does not affect electrical or mechanical performance.

Q: Do the temperature coefficients differ between these parts?

A: No. Both the OY150K and OY150KE maintain identical temperature coefficients of -1000/-1600 ppm/°C across the full operating range of -40°C to 220°C.

Q: Is the OY150KE suitable for moisture-sensitive applications?

A: Yes. The OY150KE retains the moisture-resistant feature of the OY150K. Both components are designed for applications requiring protection against moisture ingress and maintain stable performance in humid environments.
