OY105K Equivalent & Substitute Parts

Part Overview

The OY105K is a 1 MOhms ±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 OY105K is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY105K is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 MOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial
• Operating temperature range: -40°C to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Functional features: Moisture resistant and pulse withstanding

The OY105KE qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions (0.276" Dia x 0.748" L / 7.00mm x 19.00mm), and functional characteristics. The primary distinction between these components is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The OY105KE is the direct equivalent substitute for the obsolete OY105K. Both components share identical electrical and mechanical specifications, ensuring functional interchangeability in circuit applications. The OY105KE is currently in active production status with full inventory availability.

For new designs or production continuity, the OY105KE is the appropriate selection. The OY105KE provides ROHS3 compliance, whereas the OY105K is RoHS non-compliant. This compliance difference is significant for applications subject to RoHS regulatory requirements. Both components maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the OY105KE directly replace the OY105K in existing designs?

A: Yes. The OY105KE is electrically and mechanically identical to the OY105K. Both components have the same resistance value (1 MOhms), tolerance (±10%), power rating (2W), axial package configuration, and operating temperature range (-40°C to 220°C). Direct substitution is valid without circuit modification.

Q: What is the primary difference between OY105K and OY105KE?

A: The OY105K is obsolete, while the OY105KE is in active production. The OY105KE also provides ROHS3 compliance, whereas the OY105K is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both components use axial through-hole packaging with identical physical dimensions (0.276" Dia x 0.748" L / 7.00mm x 19.00mm). The OY105KE is supplied in bulk packaging, while the OY105K packaging specification is not defined in available data.

Q: What parameters must remain constant for substitution validity?

A: Resistance (1 MOhms), tolerance (±10%), power rating (2W), ceramic composition, axial package type, operating temperature range (-40°C to 220°C), and functional features (moisture resistant, pulse withstanding) must all remain constant for valid substitution.

Q: Is the OY105KE suitable for applications requiring RoHS compliance?

A: Yes. The OY105KE is ROHS3 compliant. If RoHS compliance is a design requirement, the OY105KE is the appropriate selection over the non-compliant OY105K.
