• 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 to 220°C
• Features: Moisture Resistant, Pulse Withstanding

The OX222KE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The OX222KE is the direct equivalent substitute for the obsolete OX222K. Both components share identical electrical specifications and physical dimensions, ensuring form-fit-function compatibility in existing circuit designs.

The OX222KE offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the OX222KE achieves ROHS3 compliance, whereas the OX222K is RoHS non-compliant. For applications subject to regulatory requirements or environmental compliance mandates, the OX222KE is the appropriate selection.

Both components are REACH Unaffected and classified under ECCN EAR99, with identical HTSUS coding (8533.21.0090).

Frequently Asked Questions (FAQ)

Q: Can the OX222KE be used as a direct replacement for the OX222K?
