Substitute Part Grouping Explanation

Substitute parts for the EP3WS150RJ are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant:

• Resistance value of 150 Ohms with ±5% tolerance
• Power rating of 3W
• Wirewound composition
• Axial package configuration
• Physical dimensions of 0.256" Dia x 0.689" L (6.50mm x 17.50mm)
• Operating temperature range of -55°C to 155°C
• Temperature coefficient of ±300ppm/°C
• Presence of flame retardant coating, pulse withstanding capability, and safety features
• ROHS3 compliance status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.
