Key Parameters

Substitute Part Grouping Explanation

The Ohmite 22J82RE is classified as a parametric equivalent to the 22J82R. Substitution eligibility is determined by strict matching of the following critical parameters:

• Resistance value: 82 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.220" Dia x 0.421" L (5.60mm x 10.70mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame Retardant Coating, Safety
• Series designation: 20
• Termination count: 2

The 22J82RE maintains identical electrical performance and mechanical compatibility with the 22J82R, with the primary distinction being packaging format (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 22J82R and 22J82RE are Active status components suitable for direct substitution based on electrical and mechanical equivalence. The 22J82RE offers ROHS3 compliance, making it the preferred selection for applications subject to RoHS3 regulatory requirements. The 22J82R remains suitable for applications where RoHS compliance is not mandated. Both parts maintain identical performance characteristics across resistance, tolerance, power dissipation, and thermal behavior. Selection between these parts should be based on compliance requirements specific to the end application and regional regulations.

Frequently Asked Questions (FAQ)

Q: Can the 22J82RE replace the 22J82R in existing designs? A: Yes. The 22J82RE is electrically and mechanically equivalent to the 22J82R. Both components share identical resistance values, tolerance, power ratings, physical dimensions, and thermal characteristics. Direct substitution is permissible from a functional standpoint.

Q: What is the primary difference between these two parts? A: The primary differences are packaging format and RoHS compliance status. The 22J82R is supplied in standard packaging and is RoHS non-compliant, while the 22J82RE is supplied in Bulk packaging and is ROHS3 compliant.

Q: Are the physical dimensions identical? A: Yes. Both the 22J82R and 22J82RE have identical physical dimensions of 0.220" Dia x 0.421" L (5.60mm x 10.70mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS compliance status does not alter electrical performance. Both parts deliver identical resistance, tolerance, power dissipation, and temperature coefficient specifications.

Q: Are both parts suitable for high-temperature applications? A: Both components operate with a temperature coefficient of ±30ppm/°C. Specific operating temperature limits should be confirmed against application requirements and thermal management design.

Q: Can these parts be used interchangeably in production? A: Yes, provided that regulatory compliance requirements for the end application are satisfied. If RoHS3 compliance is required, the 22J82RE must be used. If RoHS compliance is not required, either part is acceptable.
