Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 20J8K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 8 kOhms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package type: Axial
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety construction

The identified substitute part maintains identical electrical specifications and mechanical form factor, differing only in packaging configuration and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 20J8K0 and 20J8K0E are electrically and mechanically equivalent components suitable for direct substitution in axial wirewound resistor applications requiring 8 kOhms at 10W with ±5% tolerance.

The primary distinction between these parts is RoHS compliance status. The 20J8K0E is ROHS3 compliant, making it the appropriate selection for applications subject to RoHS3 regulatory requirements. The 20J8K0 is RoHS non-compliant and should be selected only when RoHS compliance is not a design constraint.

Packaging configuration differs between the two parts: the 20J8K0 is supplied in standard packaging, while the 20J8K0E is supplied in bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 20J8K0E directly replace the 20J8K0 in existing designs?

A: Yes. The 20J8K0E is electrically and mechanically equivalent to the 20J8K0. Both components share identical resistance, tolerance, power rating, composition, package type, and physical dimensions. Direct substitution is permissible from a technical standpoint.

Q: What is the difference between the 20J8K0 and 20J8K0E?

A: The primary differences are RoHS compliance status and packaging configuration. The 20J8K0E is ROHS3 compliant with bulk packaging, while the 20J8K0 is RoHS non-compliant with standard packaging. Electrical and mechanical specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, select the 20J8K0E. If RoHS compliance is not a constraint, either part is suitable based on availability and packaging requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 20J8K0 and 20J8K0E have identical dimensions of 0.394" Dia x 1.858" L (10.00mm x 47.20mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What does the "E" suffix in the 20J8K0E designation indicate?

A: The "E" suffix indicates ROHS3 compliance. This designation distinguishes the RoHS-compliant variant from the standard non-compliant version.
