Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S3-0R2J8 is determined by the following critical parameters:

• Resistance Value: Must be 200 mOhms (exact match required)
• Power Rating: Must be 3W (exact match required)
• Package / Case: Must be 6327 J-Lead (exact match required)
• Composition: Must be Wirewound (exact match required)
• Operating Temperature Range: Must support -55°C ~ 275°C (exact match required)
• Physical Dimensions: Must be 0.626" L x 0.272" W and 0.268" height (exact match required)

The S3-0R2J8 can be substituted with parts that maintain identical electrical and mechanical specifications. Tolerance variations are permitted when circuit design allows for relaxed tolerance requirements, provided all other parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The S3-0R2F1 serves as a direct substitute for the S3-0R2J8 with the primary distinction being tolerance specification. Both parts maintain identical electrical performance characteristics, mechanical dimensions, and environmental compliance certifications. The S3-0R2F1 offers ±1% tolerance compared to the ±5% tolerance of the S3-0R2J8, making it suitable for applications requiring tighter resistance accuracy. Both parts are ROHS3 compliant, REACH affected, and rated for the same operating temperature range of -55°C to 275°C. Selection between these parts should be based on circuit tolerance requirements and application-specific accuracy specifications.

Frequently Asked Questions (FAQ)

Q: Can S3-0R2F1 be used as a direct replacement for S3-0R2J8?

A: Yes. The S3-0R2F1 is electrically and mechanically compatible with the S3-0R2J8. Both parts share identical resistance values, power ratings, package configurations, and operating temperature ranges. The primary difference is tolerance specification.

Q: What is the tolerance difference between these parts?

A: The S3-0R2J8 has ±5% tolerance, while the S3-0R2F1 has ±1% tolerance. The tighter tolerance of the S3-0R2F1 provides greater resistance accuracy for precision current sensing applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 6327 J-Lead package with identical dimensions of 0.626" L x 0.272" W (15.90mm x 6.90mm) and a maximum seated height of 0.268" (6.80mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the S3-0R2J8 and S3-0R2F1 are ROHS3 compliant, REACH affected, and rated for the same operating temperature range of -55°C to 275°C.

Q: Which part should I select for my application?

A: Selection depends on your circuit's tolerance requirements. Use the S3-0R2J8 for applications tolerating ±5% resistance variation. Use the S3-0R2F1 when tighter ±1% tolerance is required for improved measurement accuracy.
