OY180K Equivalent & Substitute Parts

Part Overview

The OY180K is an 18 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 OY180K is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the OY180K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 18 Ohms
• 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 OY180KE meets all these requirements and is classified as an active product, providing continuity for applications currently using the obsolete OY180K.

Parameter Comparison

Engineering Selection Recommendations

The OY180KE is the direct substitute for the obsolete OY180K. Both components are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY180K is obsolete while the OY180KE remains in active production.

For new designs or ongoing procurement, the OY180KE is the appropriate selection. This substitute provides improved compliance status, with ROHS3 certification compared to the non-compliant RoHS status of the original part. Both components maintain equivalent performance across the specified operating temperature range and feature identical moisture resistance and pulse withstanding characteristics.

Frequently Asked Questions (FAQ)

Q: Can the OY180KE be used as a direct replacement for the OY180K?

A: Yes. The OY180KE is electrically and mechanically equivalent to the OY180K. Both components have identical resistance values (18 Ohms ±10%), power ratings (2W), physical dimensions (0.276" Dia x 0.748" L), and operating temperature ranges (-40°C ~ 220°C).

Q: What is the primary reason to substitute the OY180K?

A: The OY180K is classified as obsolete. The OY180KE provides continuity for applications requiring this component specification while maintaining active product status and improved regulatory compliance.

Q: Are there any packaging differences between these parts?

A: The OY180K is supplied in standard packaging, while the OY180KE is supplied in bulk packaging. Both maintain identical axial lead configuration and physical dimensions suitable for through-hole PCB assembly.

Q: Does the OY180KE meet current regulatory requirements?

A: The OY180KE is ROHS3 compliant and REACH unaffected, providing improved compliance status compared to the non-compliant RoHS status of the OY180K.

Q: Are the temperature coefficients identical?

A: Yes. Both the OY180K and OY180KE have identical temperature coefficients of -1000 / -1600 ppm/°C, ensuring equivalent thermal performance across the operating temperature range.
