OY183K Equivalent & Substitute Parts

Part Overview

The OY183K is an 18 kOhms ±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 OY183K is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY183K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following specifications without deviation:

• Resistance value: 18 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY183KE meets all these criteria and is classified as a direct equivalent substitute for the obsolete OY183K.

Parameter Comparison

Engineering Selection Recommendations

The OY183KE is the direct equivalent substitute for the obsolete OY183K. Both components are manufactured by Ohmite within the OY series and share identical electrical specifications and physical dimensions. The primary distinction is product status and regulatory compliance: the OY183K is obsolete, while the OY183KE is active and ROHS3 compliant. For new designs or ongoing procurement, the OY183KE is the appropriate selection. Both components maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the OY183KE be used as a direct replacement for the OY183K in existing designs?

A: Yes. The OY183KE is electrically and mechanically identical to the OY183K. Both components have the same resistance value (18 kOhms), tolerance (±10%), power rating (2W), physical dimensions (0.276" Dia x 0.748" L), and operating temperature range (-40°C ~ 220°C). Pin-for-pin and footprint compatibility is assured.

Q: What is the difference between OY183K and OY183KE?

A: The OY183K is classified as obsolete, while the OY183KE is an active product. The OY183KE is ROHS3 compliant, whereas the OY183K is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: Both components use axial packaging with identical physical dimensions. The OY183K is supplied in standard packaging, while the OY183KE is available in bulk packaging. The component form factor and lead configuration are identical.

Q: Is the OY183KE suitable for high-temperature applications?

A: Yes. The OY183KE operates across the temperature range of -40°C to 220°C with a temperature coefficient of -1000 / -1600 ppm/°C, identical to the OY183K. Both components are rated for the same thermal performance envelope.

Q: What certifications apply to the OY183KE?

A: The OY183KE is ROHS3 compliant and REACH Unaffected. It carries EAR99 export classification. These certifications ensure compliance with current regulatory requirements for electronic components.
