OY124K Equivalent & Substitute Parts

Part Overview

The OY124K is a 120 kOhms ±10% 2W axial through-hole resistor manufactured by Ohmite with ceramic composition. This component features moisture resistance and pulse withstanding capabilities, designed for operating temperatures from -40°C to 220°C. The OY124K is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the OY124K is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match:

• Resistance value: 120 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial through-hole
• Physical dimensions: 0.276" Dia × 0.748" L
• Temperature coefficient: -1000/-1600 ppm/°C
• Operating temperature range: -40°C to 220°C
• Features: Moisture resistant and pulse withstanding

The OY124KE meets all these criteria and is identified as a direct substitute for the obsolete OY124K.

Parameter Comparison

Engineering Selection Recommendations

The OY124KE is the direct equivalent substitute for the obsolete OY124K. Both components are manufactured by Ohmite within the OY series and maintain identical electrical specifications and physical dimensions. The primary distinction is product status: the OY124K is obsolete while the OY124KE is active and currently available.

The OY124KE offers an additional advantage in regulatory compliance, meeting ROHS3 standards, whereas the OY124K is RoHS non-compliant. For new designs or system updates, the OY124KE is the appropriate selection. Both components maintain REACH Unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the OY124KE be used as a direct replacement for the OY124K?

A: Yes. The OY124KE is electrically and mechanically identical to the OY124K across all specified parameters, including resistance, tolerance, power rating, composition, package type, dimensions, and operating temperature range.

Q: What is the primary reason to substitute the OY124K?

A: The OY124K is classified as obsolete. The OY124KE provides continued access to equivalent functionality with active product status and improved regulatory compliance.

Q: Are there any dimensional differences between these parts?

A: No. Both the OY124K and OY124KE share identical physical dimensions of 0.276" Dia × 0.748" L (7.00mm × 19.00mm) and are packaged as axial through-hole components.

Q: What is the difference in RoHS compliance?

A: The OY124K is RoHS non-compliant, while the OY124KE is ROHS3 compliant. For applications requiring RoHS compliance, the OY124KE is the appropriate selection.

Q: Are the electrical characteristics identical?

A: Yes. Both parts maintain 120 kOhms resistance at ±10% tolerance, 2W power rating, -1000/-1600 ppm/°C temperature coefficient, and -40°C to 220°C operating temperature range.
