Key Parameters

Substitute Part Grouping Explanation

The 90J20KE is classified as a parametric equivalent to the 90J20K. Substitution is valid based on the following matching criteria:

• Resistance value: 20 kOhms (identical)
• Tolerance: ±5% (identical)
• Power rating: 11W (identical)
• Composition: Wirewound (identical)
• Package type: Axial (identical)
• Physical dimensions: 0.343" Dia x 1.811" L (identical)
• Temperature coefficient: ±30ppm/°C (identical)
• Features: Flame Retardant Coating, Safety (identical)
• Number of terminations: 2 (identical)

Both parts are manufactured by Ohmite and maintain the same electrical performance and mechanical fit characteristics. The primary difference is packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J20K and 90J20KE are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and packaging needs.

The 90J20K is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required. The 90J20KE provides ROHS3 compliance, making it the appropriate choice for applications subject to RoHS regulations or where compliance documentation is mandated. Both parts maintain identical performance characteristics and physical compatibility, ensuring direct substitution capability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 90J20KE replace the 90J20K in existing designs?
