Substitute Part Grouping Explanation

Substitute parts for the F10J2R0 are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Resistance value: 2 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Temperature coefficient: ±400ppm/°C
• Operating temperature range: -55°C to 350°C
• Coating type: Vitreous Enamel Coated
• Mounting configuration: Flange Braces, Right Angle
• Lead style: Solder Lugs
• Package type: Radial, Flat Oval
• Physical dimensions: 0.750" L x 0.375" W (19.05mm x 9.53mm)

The F10J2R0E meets all these criteria and qualifies as a parametric equivalent. The primary difference between the main part and its substitute is packaging configuration and compliance certification status.
