Substitute Part Grouping Explanation

The Ohmite 20J35RE qualifies as a direct substitute for the 20J35R based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 35 Ohms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 10W (exact match)
• Composition: Wirewound (exact match)
• Package type: Axial (exact match)
• Physical dimensions: 0.394" Dia x 1.858" L (exact match)
• Temperature coefficient: ±30ppm/°C (exact match)
• Features: Flame retardant coating and safety features (exact match)
• Terminations: 2 (exact match)

The primary difference between these parts is packaging configuration and RoHS compliance status, which do not affect electrical or mechanical compatibility in circuit applications.
