Substitute Part Grouping Explanation

Substitution for the Ohmite 90J6K2 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 6.2 kΩ (exact match required)
• Tolerance: ±5% (electrical accuracy specification)
• Power Rating: 11W (thermal dissipation capability)
• Composition: Wirewound (construction type)
• Package Type: Axial (form factor and termination style)
• Temperature Coefficient: ±30ppm/°C (temperature stability)
• Features: Flame Retardant Coating, Safety (regulatory and safety requirements)
• Physical Dimensions: 0.343" Dia × 1.811" L (board layout compatibility)

The Ohmite 90J6K2E qualifies as a parametric equivalent because it matches all critical electrical and mechanical specifications. The primary distinction is packaging format (Bulk vs. standard) and RoHS compliance status, which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 90J6K2 and 90J6K2E are Active products from the same manufacturer and series, with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

90J6K2: Select this part number when RoHS non-compliant components are acceptable for the application and standard packaging is required.

90J6K2E: Select this part number when ROHS3 compliance is mandated by design or regulatory requirements, or when bulk packaging is preferred for high-volume procurement. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions during storage and handling.

Both parts are suitable for direct substitution in circuit designs requiring 6.2 kΩ, 11W, ±5% tolerance wirewound resistors with flame retardant and safety features.

Frequently Asked Questions (FAQ)

Q: Can the 90J6K2E be used as a direct replacement for the 90J6K2?

A: Yes. The 90J6K2E is a parametric equivalent with identical resistance, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. The parts are functionally interchangeable in circuit applications.

Q: What is the difference between the 90J6K2 and 90J6K2E?

A: The primary differences are packaging format (standard vs. Bulk) and RoHS compliance status. The 90J6K2 is RoHS non-compliant, while the 90J6K2E is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical functional characteristics in circuit operation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 90J6K2 and 90J6K2E measure 0.343" diameter × 1.811" length (8.70mm × 46.00mm), ensuring identical board layout compatibility and mounting requirements.

Q: What does MSL 1 (Unlimited) mean for the 90J6K2E?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This simplifies inventory management and procurement logistics.

Q: Can these parts be used in high-temperature applications?

A: The temperature coefficient of ±30ppm/°C applies to both parts. Specific operating temperature limits are not provided in the component specifications. Consult application requirements and thermal design calculations to confirm suitability for target operating conditions.

Q: Are both parts suitable for safety-critical applications?

A: Both the 90J6K2 and 90J6K2E feature flame retardant coating and safety construction. Confirm that these safety features meet the specific regulatory and application requirements for your design.
