OY100K Equivalent & Substitute Parts

Part Overview

The OY100K is a 10 Ohm, 2W axial through-hole resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. This part is classified as obsolete, making identification of compatible substitutes essential for ongoing design support and procurement continuity. The OY100K operates across a temperature range of -40°C to 220°C with a tolerance of ±10% and is RoHS non-compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY100K is determined by strict equivalence across electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value (10 Ohms), tolerance (±10%), power rating (2W), composition (ceramic), package configuration (axial), operating temperature range (-40°C to 220°C), and physical dimensions (0.276" Dia x 0.748" L). The OY100KE meets all these criteria and is therefore a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OY100KE is the direct substitute for the obsolete OY100K. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status: the OY100K is obsolete while the OY100KE is active in production. Additionally, the OY100KE achieves ROHS3 compliance, whereas the OY100K is RoHS non-compliant. For new designs or ongoing procurement, the OY100KE should be selected to ensure component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OY100KE be used as a direct replacement for the OY100K? A: Yes. The OY100KE is electrically and mechanically identical to the OY100K across all specified parameters, including resistance, tolerance, power rating, composition, package type, operating temperature range, and physical dimensions.

Q: What is the primary reason to substitute the OY100K? A: The OY100K is classified as obsolete. The OY100KE is the active production equivalent, ensuring long-term component availability and supply chain continuity.

Q: Are there any compliance differences between these parts? A: Yes. The OY100KE is ROHS3 compliant, while the OY100K is RoHS non-compliant. For applications requiring RoHS compliance, the OY100KE is the appropriate selection.

Q: Do the physical dimensions match between OY100K and OY100KE? A: Yes. Both parts have identical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm) and use the same axial package configuration, ensuring mechanical compatibility in existing PCB layouts.

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