OX220K Equivalent & Substitute Parts

Part Overview

The OX220K is a 22 Ohm, 1W axial through-hole resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. The part is currently obsolete, making identification of active equivalent components essential for ongoing production, maintenance, and design updates. Substitute parts must maintain identical electrical specifications and physical dimensions to ensure direct compatibility in existing circuit designs.

Substitute Part Grouping Explanation

Substitution for the OX220K is determined by strict equivalence across the following parameters:

• Resistance value: 22 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000/-1600ppm/°C
• Functional features: Moisture Resistant, Pulse Withstanding

The OX220KE meets all these criteria and is classified as a parametric equivalent. Substitution is valid based on complete alignment of electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OX220KE is the direct active equivalent for the obsolete OX220K. Both parts are manufactured by Ohmite within the OX series and share identical electrical and mechanical specifications. The OX220KE offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The OX220KE achieves RoHS compliance, whereas the OX220K is non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the OX220KE is the appropriate selection. Both parts carry the same ECCN classification (EAR99) for export control purposes.

Physical compatibility is confirmed: both parts maintain the same axial package dimensions (0.217" Dia x 0.650" L), enabling direct board-level substitution without layout modifications or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can OX220KE be used as a direct replacement for OX220K?

A: Yes. The OX220KE is a parametric equivalent with identical resistance (22 Ohms), tolerance (±10%), power rating (1W), composition (ceramic), package type (axial), and physical dimensions (0.217" Dia x 0.650" L). Direct substitution is valid for all electrical and mechanical applications.

Q: What is the primary difference between OX220K and OX220KE?

A: The OX220K is obsolete, while the OX220KE is active. The OX220KE also achieves RoHS compliance. All electrical and mechanical parameters remain identical.

Q: Are there any packaging differences between these parts?

A: The OX220K is supplied in standard packaging, while the OX220KE is supplied in bulk packaging. Both maintain identical axial dimensions and termination configuration, ensuring compatibility in circuit board assembly.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance reflects manufacturing process and material sourcing standards, not electrical performance. Both parts deliver identical electrical characteristics across the specified operating temperature range (-40°C ~ 220°C).

Q: Can these parts be used interchangeably in moisture-sensitive applications?

A: Yes. Both the OX220K and OX220KE feature moisture-resistant construction and pulse-withstanding ceramic composition, making them suitable for applications requiring environmental protection.
