Key Parameters

Substitute Part Grouping Explanation

The Ohmite 90J56RE is a parametric equivalent to the 90J56R. Substitution is valid based on the following matching criteria:

• Resistance value: 56 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 11W (identical)
• Composition: Wirewound (identical)
• Package / Case: Axial (identical)
• Physical dimensions: 0.343" Dia x 1.811" L (8.70mm x 46.00mm) (identical)
• Temperature coefficient: ±30ppm/°C (identical)
• Features: Flame retardant coating, safety construction (identical)
• Terminations: 2 (identical)

The primary difference between these parts is packaging format (Bulk for 90J56RE versus standard for 90J56R) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J56R and 90J56RE are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements:

• Use 90J56R where RoHS non-compliant components are acceptable and standard packaging is required.
• Use 90J56RE where ROHS3 compliance is mandated or where bulk packaging is preferred. The 90J56RE provides enhanced environmental compliance with ROHS3 certification.

Both parts are suitable for direct substitution in applications requiring 56 Ohm, 11W axial wirewound resistors with flame retardant coating and safety construction.

Frequently Asked Questions (FAQ)

Q: Can 90J56RE replace 90J56R in all applications?

A: Yes. The 90J56RE is electrically and mechanically identical to the 90J56R. The primary difference is RoHS compliance status (ROHS3 Compliant versus non-compliant) and packaging format (Bulk). If your application or supply chain requires RoHS3 compliance, the 90J56RE is the appropriate choice.

Q: What is the difference between the packaging formats?

A: The 90J56R uses standard packaging, while the 90J56RE uses bulk packaging. Both contain identical components with the same electrical and mechanical properties. Packaging format selection depends on inventory management and supply chain requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.343" Dia x 1.811" L (8.70mm x 46.00mm), ensuring compatibility in PCB layouts and mechanical assemblies.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. The 90J56RE carries ROHS3 certification, while the 90J56R does not. Selection depends on regulatory requirements for your application or region.

Q: Are there any performance differences between these parts?

A: No. Both parts have identical electrical performance: 56 Ohms resistance, ±5% tolerance, 11W power rating, ±30ppm/°C temperature coefficient, and flame retardant coating with safety construction.
