Substitute Part Grouping Explanation

The Ohmite 90J10KE is identified as a direct substitute for the 90J10K based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 10 kOhms (identical)
• Tolerance: ±5% (identical)
• Power rating: 11W (identical)
• Composition: Wirewound (identical)
• Package / Case: Axial (identical)
• Physical dimensions: 0.343" Dia x 1.811" L (identical)
• Temperature coefficient: ±30ppm/°C (identical)
• Features: Flame retardant coating and safety construction (identical)
• Number of terminations: 2 (identical)

The primary distinction between these parts is RoHS compliance status. The 90J10KE achieves ROHS3 compliance, whereas the 90J10K is RoHS non-compliant. Both parts maintain identical thermal, electrical, and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 90J10K and 90J10KE should be based on regulatory and compliance requirements:

• 90J10K: Select when RoHS compliance is not a design constraint and cost optimization is prioritized. Both parts are active in production with adequate inventory levels.

• 90J10KE: Select when ROHS3 compliance is mandatory for the application or end-market. This variant meets current environmental and regulatory standards while maintaining identical electrical and thermal performance.

Both parts are functionally interchangeable in circuit applications where the specified electrical parameters (10 kOhms, ±5%, 11W) and physical form factor (axial, 0.343" Dia x 1.811" L) are required. No performance degradation or functional differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Are the 90J10K and 90J10KE electrically identical?

A: Yes. Both parts have identical resistance (10 kOhms), tolerance (±5%), power rating (11W), temperature coefficient (±30ppm/°C), and composition (wirewound). Electrical performance is equivalent.

Q: Can I use the 90J10KE as a direct replacement for the 90J10K?

A: Yes. The 90J10KE is a direct substitute. Physical dimensions, package type (axial), and all electrical specifications are identical. The primary difference is RoHS compliance status.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant?

A: The 90J10K is RoHS non-compliant, while the 90J10KE meets ROHS3 compliance standards. ROHS3 compliance indicates the part meets current environmental regulations restricting hazardous substances. Selection depends on regulatory requirements for your application.

Q: Do these parts have the same physical dimensions?

A: Yes. Both the 90J10K and 90J10KE have identical dimensions of 0.343" Dia x 1.811" L (8.70mm x 46.00mm) and use the same axial package type. They are mechanically interchangeable.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±30ppm/°C, indicating stable resistance performance across the operating temperature range.

Q: Are both parts currently in production?

A: Yes. Both the 90J10K and 90J10KE are active products with current inventory availability (1,057 and 899 units respectively).
