Substitute Part Grouping Explanation

Substitute parts for the Ohmite 90J3K3 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match identically for substitution eligibility:

• Resistance value: 3.3 kOhms
• Tolerance: ±5%
• Power rating: 11W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.343" Dia x 1.811" L
• Temperature coefficient: ±30ppm/°C
• Safety and flame retardant features

Parts meeting all these criteria are classified as parametric equivalents and are directly interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J3K3 and 90J3K3E are Active product status components from Ohmite's Series 90 wirewound resistor line. The primary distinction between these parts is RoHS compliance status. The 90J3K3E carries RoHS3 compliance certification, while the 90J3K3 is RoHS non-compliant. Selection between these parts depends on regulatory and procurement requirements specific to the application and end-use market. All other electrical, mechanical, and safety parameters are identical, ensuring direct functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 90J3K3E be used as a direct replacement for the 90J3K3?
