Substitute Part Grouping Explanation

Substitution of the S3-2K2J8 is determined by strict equivalence in the following critical parameters:

• Resistance value: 2.2 kOhms (exact match required)
• Power rating: 3W (exact match required)
• Package / Case: 6327 J-Lead (exact match required)
• Composition: Wirewound (exact match required)
• Operating temperature range: -55°C ~ 275°C (exact match required)
• Physical dimensions: 0.626" L x 0.272" W, height 0.268" max (exact match required)

The S3-2K2F1 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. The primary difference is tolerance specification: S3-2K2F1 offers ±1% tolerance compared to the ±5% tolerance of S3-2K2J8. This represents an upgrade in precision while maintaining full compatibility with existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both S3-2K2J8 and S3-2K2F1 are Active products with ROHS3 compliance and REACH affected status. Selection between these parts should be based on tolerance requirements for the specific application. The S3-2K2J8 with ±5% tolerance is suitable for applications where standard precision is acceptable. The S3-2K2F1 with ±1% tolerance provides enhanced precision for circuits requiring tighter resistance values. Both parts maintain identical electrical performance characteristics, thermal specifications, and mechanical compatibility. Current inventory levels show 1485 units available for S3-2K2F1 compared to 817 units for S3-2K2J8.
