OY120K Equivalent & Substitute Parts

Part Overview

The OY120K is a 12 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 OY120K 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 OY120K is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 12 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Operating temperature range: -40°C to 220°C
• Physical dimensions: 0.276" Dia × 0.748" L (7.00mm × 19.00mm)
• Features: Moisture Resistant, Pulse Withstanding

The OY120KE meets all specified electrical and mechanical requirements for direct substitution. Both components are manufactured by Ohmite and share identical resistance, tolerance, power rating, composition, package type, and operating specifications.

Parameter Comparison

Engineering Selection Recommendations

The OY120KE is the direct equivalent substitute for the obsolete OY120K. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the OY120K is obsolete while the OY120KE is active and available for procurement.

The OY120KE offers an additional compliance advantage: it is ROHS3 compliant, whereas the OY120K is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the OY120KE provides regulatory alignment while maintaining full electrical and mechanical compatibility.

Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring consistent export and regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the OY120KE be used as a direct replacement for the OY120K?

A: Yes. The OY120KE is electrically and mechanically equivalent to the OY120K. Both components have identical resistance (12 Ohms), tolerance (±10%), power rating (2W), composition (ceramic), package type (axial), physical dimensions, and operating temperature range (-40°C to 220°C).

Q: What is the primary reason to substitute the OY120K?

A: The OY120K is classified as obsolete. The OY120KE is the active equivalent part from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: Yes. The OY120KE is ROHS3 compliant, while the OY120K is RoHS non-compliant. For applications requiring RoHS compliance, the OY120KE is the appropriate selection.

Q: Do the physical dimensions match between OY120K and OY120KE?

A: Yes. Both components have identical dimensions of 0.276" Dia × 0.748" L (7.00mm × 19.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Are the temperature coefficients identical?

A: Yes. Both the OY120K and OY120KE have identical temperature coefficients of -1000/-1600ppm/°C and operate across the same temperature range of -40°C to 220°C.

Q: What packaging options are available?

A: The OY120KE is supplied in bulk packaging. The OY120K packaging specification was not provided in the available data.
