Substitute Part Grouping Explanation

Substitution eligibility for the S2-0R01J3 is determined by strict equivalence in the following critical parameters:

• Resistance value: 10 mOhms (exact match required)
• Power rating: 1W (exact match required)
• Package / Case: 2615 J-Lead (exact match required)
• Operating temperature range: -55°C to 275°C (exact match required)
• Physical dimensions: 0.260" L x 0.154" W, height 0.142" max (exact match required)
• Composition: Wirewound (exact match required)
• Features: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety (all required)

The S2-0R01F1 qualifies as a direct substitute based on identical electrical specifications, mechanical compatibility, and environmental performance. The tolerance specification difference (±1% versus ±5%) represents an upgrade in precision capability while maintaining full backward compatibility with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the S2-0R01J3 and S2-0R01F1 are active products with identical ROHS3 compliance and REACH affected status. Selection between these parts depends on tolerance requirements for the specific application. The S2-0R01J3 with ±5% tolerance is suitable for general current sensing applications where standard precision is acceptable. The S2-0R01F1 with ±1% tolerance provides enhanced precision for applications requiring tighter resistance value control. Both components maintain full mechanical and thermal compatibility, identical package footprints, and equivalent environmental performance across the -55°C to 275°C operating range. Component selection should be based on circuit tolerance budgets and measurement accuracy requirements.
