OY222K Equivalent & Substitute Parts

Part Overview

The OY222K is a 2.2 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 OY222K is 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 OY222K is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 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 OY222KE meets all these criteria and is classified as a direct substitute for the obsolete OY222K.

Parameter Comparison

Engineering Selection Recommendations

The OY222KE is the direct equivalent substitute for the obsolete OY222K. Both components are manufactured by Ohmite within the OY series and maintain identical electrical and mechanical specifications across all critical parameters including resistance, tolerance, power rating, package dimensions, and operating temperature range.

The primary distinction between the two parts is product status and regulatory compliance. The OY222K is obsolete, while the OY222KE is active and ROHS3 compliant, making it the appropriate selection for new designs and ongoing production requirements. The OY222KE provides equivalent functional performance with improved regulatory standing for modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the OY222KE be used as a direct replacement for the OY222K in existing designs?

A: Yes. The OY222KE is electrically and mechanically identical to the OY222K across all specified parameters, including resistance value, tolerance, power rating, physical dimensions, and operating temperature range. The components are pin-compatible and functionally equivalent.

Q: What is the difference between OY222K and OY222KE?

A: The OY222K is classified as obsolete, while the OY222KE is an active product. The OY222KE is ROHS3 compliant, whereas the OY222K is RoHS non-compliant. Both components share identical electrical and mechanical specifications.

Q: Are there any packaging differences between these parts?

A: The OY222K and OY222KE both use axial packaging with identical physical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm). The OY222KE is supplied in bulk packaging, while the OY222K packaging specification is listed as standard.
