Key Parameters

Substitute Part Grouping Explanation

Substitution for the S3-0R015J8 is determined by the following critical parameters:

• Resistance Value: Must be 15 mOhms
• Power Rating: Must be 3W minimum
• Package / Case: Must be 6327 J-Lead
• Operating Temperature Range: Must support -55°C to 275°C
• Physical Dimensions: Must match 0.626" L x 0.272" W (15.90mm x 6.90mm)
• Composition: Wirewound construction required
• Compliance: ROHS3 and REACH compliance required

The S3-0R015F1 qualifies as a direct substitute based on identical electrical specifications, package configuration, and environmental ratings. The primary distinction is tolerance specification, which is tighter in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The S3-0R015F1 is a direct substitute for the S3-0R015J8 in applications where component interchangeability is required. Both parts maintain identical mechanical fit, thermal performance, and regulatory compliance status. The S3-0R015F1 provides improved tolerance specification at ±1% compared to the ±5% tolerance of the main part, making it suitable for precision current sensing applications requiring tighter resistance accuracy. Both parts are active products with full ROHS3 and REACH compliance, ensuring long-term availability and regulatory alignment. Selection between these parts should be based on application tolerance requirements and inventory availability.
