Riedon S1-0R2J8 Equivalent & Substitute Parts

Part Overview

The Riedon S1-0R2J8 is a 200 mOhms ±5% wirewound chip resistor rated at 0.5W (1/2W) in a 1913 J-Lead package. This current sense resistor is designed for applications requiring precision low-resistance measurements with flame-proof, moisture-resistant, and pulse-withstanding characteristics. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement while maintaining circuit performance and compliance requirements.

Substitute Part Grouping Explanation

Substitute parts for the S1-0R2J8 are qualified based on the following criteria:

• Identical resistance value: 200 mOhms
• Identical power rating: 0.5W (1/2W)
• Identical package: 1913 J-Lead
• Identical composition: Wirewound
• Identical operating temperature range: -55°C ~ 275°C
• Identical features: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety
• Identical RoHS and compliance status: ROHS3 Compliant, REACH Affected

Tolerance variations within the same electrical class are permitted when the substitute part meets or exceeds the performance requirements of the original specification. The S1-0R2F1 qualifies as a direct substitute with improved tolerance specification (±1% versus ±5%).

Parameter Comparison
