Substitute Part Grouping Explanation

Substitution of the Riedon S5-2K2J8 is permissible with the Riedon S5-2K2F1 based on the following criteria:

Matching Parameters (Substitution Basis):

• Identical resistance value: 2.2 kOhms
• Identical power rating: 4W
• Identical package / case: 8230 J-Lead
• Identical composition: Wirewound
• Identical operating temperature range: -55°C ~ 275°C
• Identical temperature coefficient: ±20ppm/°C
• Identical features: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

Differentiating Parameter:

• Tolerance: S5-2K2J8 specifies ±5%, while S5-2K2F1 specifies ±1%

The S5-2K2F1 represents an upgrade path where tighter tolerance specifications are required for the application.

Parameter Comparison

Engineering Selection Recommendations

Both the S5-2K2J8 and S5-2K2F1 maintain Active product status and full ROHS3 compliance with REACH affected designation. Selection between these components is determined by tolerance requirements:

The S5-2K2J8 (±5% tolerance) is suitable for applications where standard tolerance specifications are acceptable. The S5-2K2F1 (±1% tolerance) is appropriate for applications requiring precision resistance values with tighter tolerance control. Both components share identical mechanical, thermal, and environmental characteristics, ensuring direct substitution capability within the specified tolerance parameters.

Frequently Asked Questions (FAQ)

Q: Can the S5-2K2F1 directly replace the S5-2K2J8 in existing designs?

A: Yes. The S5-2K2F1 is mechanically and electrically compatible with the S5-2K2J8. The primary difference is tolerance specification (±1% versus ±5%), which represents an upgrade in precision. No circuit modifications or layout changes are required.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable deviation from the nominal 2.2 kOhms resistance value. The S5-2K2J8 allows ±5% deviation (2.09 kOhms to 2.31 kOhms), while the S5-2K2F1 allows ±1% deviation (2.178 kOhms to 2.222 kOhms). Applications requiring tighter resistance accuracy should specify the S5-2K2F1.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components use the 8230 J-Lead package with identical dimensions: 0.819" L x 0.296" W (20.80mm x 7.50mm) and maximum seated height of 0.319" (8.10mm).

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the S5-2K2J8 and S5-2K2F1 are ROHS3 compliant, REACH affected, and rated for identical operating temperature ranges (-55°C ~ 275°C) with MSL 1 (Unlimited) moisture sensitivity.

Q: Which part should be selected for new designs?

A: Selection depends on application tolerance requirements. For standard tolerance applications, either part is acceptable. For precision current sensing or measurement circuits requiring tighter tolerance control, the S5-2K2F1 is the appropriate selection.
