OY104K Equivalent & Substitute Parts

Part Overview

The OY104K is a 100 kOhms ±10% 2W through-hole axial resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. The part operates across a temperature range of -40°C to 220°C and features a temperature coefficient of -1000/-1600ppm/°C. Currently classified as obsolete, this part requires identification of active equivalent alternatives to maintain supply chain continuity for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY104K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY104KE maintains identical specifications for resistance value, tolerance, power rating, ceramic composition, axial package configuration, physical dimensions, operating temperature range, temperature coefficient, and functional features. Both parts are manufactured by Ohmite within the OY series and share the same termination configuration. The primary distinction is product status: OY104K is obsolete while OY104KE is active, making OY104KE the direct functional equivalent for ongoing applications.

Parameter Comparison

Engineering Selection Recommendations

OY104KE is the direct substitute for OY104K. Both parts are electrically and mechanically identical across all specified parameters. The OY104KE offers the advantage of active product status with ROHS3 compliance, compared to the obsolete status and RoHS non-compliance of OY104K. For new designs and production requiring 100 kOhms ±10% 2W ceramic axial resistors with moisture resistance and pulse-withstanding capability, OY104KE provides continuity of supply with improved regulatory compliance. Existing inventory of OY104K can be used interchangeably with OY104KE in applications where the specified electrical and thermal characteristics are required.

Frequently Asked Questions (FAQ)

Q: Can OY104KE be used as a direct replacement for OY104K? A: Yes. OY104KE is a direct substitute with identical electrical specifications (100 kOhms ±10%, 2W), ceramic composition, axial package configuration, physical dimensions (7.00mm x 19.00mm), operating temperature range (-40°C to 220°C), and functional features (moisture resistant, pulse withstanding).

Q: What is the primary reason to transition from OY104K to OY104KE? A: OY104K is classified as obsolete, while OY104KE is an active product. OY104KE also provides ROHS3 compliance, whereas OY104K is RoHS non-compliant. For ongoing production and new designs, OY104KE ensures supply chain continuity and regulatory compliance.

Q: Are there any physical or dimensional differences between these parts? A: No. Both parts share identical physical dimensions of 0.276" diameter by 0.748" length (7.00mm x 19.00mm) and are packaged in axial configuration with two terminations.

Q: Do these parts have the same temperature performance characteristics? A: Yes. Both OY104K and OY104KE operate across -40°C to 220°C with an identical temperature coefficient of -1000/-1600ppm/°C.

Q: Is OY104KE available in different packaging options? A: OY104KE is supplied in bulk packaging, while OY104K was supplied with standard packaging. Both maintain the same axial component form factor suitable for through-hole PCB assembly.
