Substitute Part Grouping Explanation

Substitution of the B20J2K0 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part B20J2K0E maintains identical specifications for resistance value, tolerance, power rating, composition, package configuration, temperature coefficient, and physical dimensions. Both parts are manufactured by Ohmite within the same Brown Devil® 200 series, ensuring mechanical and thermal compatibility. The substitution is valid when the following parameters match exactly:

• Resistance: 2 kOhms
• Tolerance: ±5%
• Power Rating: 20W
• Composition: Wirewound
• Package/Case: Axial
• Temperature Coefficient: ±260ppm/°C
• Physical Dimensions: 0.437" Dia x 2.000" L

Parameter Comparison

Engineering Selection Recommendations

Both B20J2K0 and B20J2K0E are active production parts from Ohmite with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status. The B20J2K0 is RoHS non-compliant, while the B20J2K0E is ROHS3 compliant and REACH unaffected. Selection between these parts should be based on the regulatory requirements of the end application and target market. For applications requiring RoHS3 compliance, B20J2K0E is the appropriate selection. For applications without RoHS compliance requirements, either part is electrically and mechanically equivalent. Current inventory availability shows B20J2K0E at 1269 pieces compared to B20J2K0 at 900 pieces.
