OY154K Equivalent & Substitute Parts

Part Overview

The OY154K is a 150 kOhms ±10% 2W through-hole axial resistor manufactured by Ohmite with ceramic composition. This component 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 OY154K is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY154K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute must maintain identical resistance value (150 kOhms), tolerance (±10%), power rating (2W), composition (ceramic), axial package configuration, and operating temperature range (-40°C to 220°C). The temperature coefficient specification (-1000/-1600 ppm/°C) and feature set (moisture resistance and pulse withstanding) must also be preserved. The OY154KE meets all these criteria as a direct equivalent from the same manufacturer within the OY series.

Parameter Comparison

Engineering Selection Recommendations

The OY154KE is the direct equivalent substitute for the obsolete OY154K. Both components are manufactured by Ohmite and share identical electrical specifications, mechanical dimensions, and performance characteristics. The primary distinction is product status: the OY154K is obsolete while the OY154KE remains in active production. Additionally, the OY154KE achieves ROHS3 compliance, whereas the OY154K is RoHS non-compliant. For new designs and ongoing production requiring this 150 kOhms 2W axial ceramic resistor, the OY154KE provides full functional equivalence with the advantage of current availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OY154KE be used as a direct replacement for the OY154K? A: Yes. The OY154KE is electrically and mechanically identical to the OY154K across all specified parameters, including resistance value, tolerance, power rating, package dimensions, and operating temperature range.

Q: What is the primary reason to substitute the OY154K? A: The OY154K is classified as obsolete. The OY154KE provides the same functionality while remaining in active production with current availability.

Q: Are there any compliance differences between these parts? A: Yes. The OY154KE is ROHS3 compliant, while the OY154K is RoHS non-compliant. For applications subject to RoHS regulations, the OY154KE is the appropriate selection.

Q: Do the physical dimensions match between OY154K and OY154KE? A: Yes. Both components have identical axial package dimensions of 0.276" diameter by 0.748" length (7.00mm x 19.00mm), ensuring direct board-level compatibility.

Q: Are the electrical characteristics identical? A: Yes. Both parts maintain 150 kOhms resistance at ±10% tolerance, 2W power rating, ceramic composition, -1000/-1600 ppm/°C temperature coefficient, and -40°C to 220°C operating temperature range.
