Engineering Selection Recommendations

The Ohmite 90J27KE is a direct parametric equivalent to the 90J27K. Both components are Active product status and share identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements specific to the application:

• 90J27K: Suitable for applications where RoHS non-compliance is acceptable or not required.
• 90J27KE: Recommended for applications requiring ROHS3 compliance. This variant provides equivalent performance with enhanced regulatory alignment.

Both parts are manufactured by Ohmite within the same Series 90 product line and maintain identical resistance, tolerance, power rating, composition, package type, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 90J27KE replace the 90J27K in existing designs?

A: Yes. The 90J27KE is a direct parametric equivalent with identical electrical specifications (27 kOhms ±5%, 11W), composition (wirewound), package type (axial), and physical dimensions (0.343" Dia x 1.811" L). No circuit modifications are required.

Q: What is the difference between the 90J27K and 90J27KE?

A: The primary differences are packaging format (standard vs. Bulk) and RoHS compliance status. The 90J27K is RoHS non-compliant, while the 90J27KE is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 90J27K and 90J27KE have identical dimensions of 0.343" Dia x 1.811" L (8.70mm x 46.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards but does not alter the electrical performance or functional characteristics of the resistor. Both parts deliver identical 27 kOhms ±5% resistance at 11W power rating.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±30ppm/°C, indicating the resistance change per degree Celsius across the operating temperature range.

Q: Are these components suitable for high-temperature applications?

A: Both the 90J27K and 90J27KE feature wirewound construction with flame retardant coating and safety characteristics. Specific operating temperature limits are not provided in the parametric data; application-specific thermal analysis is required.
