Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX472K is determined by the following critical parameters:

• Resistance Value: 4.7 kOhms (exact match required)
• Tolerance: ±10% (exact match required)
• Power Rating: 1W (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.217" Dia x 0.650" L (exact match required)
• Composition: Ceramic (exact match required)
• Operating Temperature Range: -40°C ~ 220°C (exact match required)
• Features: Moisture Resistant, Pulse Withstanding (exact match required)

The OX472KE is a direct substitute manufactured by Ohmite with identical electrical and mechanical specifications. The primary distinction is product status: OX472KE is active and RoHS3 compliant, whereas OX472K is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The OX472KE is the direct equivalent for the obsolete OX472K. Both components share identical electrical specifications, mechanical dimensions, and functional characteristics. The OX472KE is the recommended selection for new designs and component replacement due to its active product status and RoHS3 compliance. The transition from OX472K to OX472KE presents no functional or compatibility concerns, as all critical parameters remain unchanged. RoHS3 compliance of the OX472KE aligns with current regulatory requirements for electronic component procurement.
