Substitute Part Grouping Explanation

Substitute parts for the Ohmite 20J2K7 are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Temperature coefficient: ±30ppm/°C
• Safety features: Flame retardant coating

The substitute part 20J2K7E meets all these criteria and is therefore electrically and mechanically interchangeable with the primary part number 20J2K7.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J2K7 and 20J2K7E are Active status components from Ohmite's Series 20 wirewound resistor line. The primary distinction between these parts is regulatory compliance status. The 20J2K7E is ROHS3 compliant, whereas the 20J2K7 is RoHS non-compliant. Both parts share identical electrical specifications, physical dimensions, and safety features. Selection between these parts should be based on project-specific regulatory requirements and compliance mandates applicable to the end application. Both parts maintain REACH Unaffected status and EAR99 export classification.
