Key Parameters

Substitute Part Grouping Explanation

The S2-0R75F1 qualifies as a direct substitute for the S2-0R75J8 based on the following critical parameters:

• Identical resistance value: 750 mOhms
• Identical power rating: 1W
• Identical package: 2615 J-Lead
• Identical physical dimensions: 0.260" L x 0.154" W (6.60mm x 3.90mm)
• Identical operating temperature range: -55°C ~ 275°C
• Identical composition: Wirewound
• Identical features: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety
• Identical RoHS and REACH compliance status

The primary difference is tolerance specification: S2-0R75F1 provides ±1% tolerance compared to ±5% tolerance of the S2-0R75J8. This represents an upgrade path for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

Both S2-0R75J8 and S2-0R75F1 are Active status components from Riedon with identical ROHS3 and REACH compliance certifications. Selection between these parts depends on tolerance requirements:

Use S2-0R75J8 when ±5% tolerance meets circuit specifications and cost optimization is prioritized.

Use S2-0R75F1 when ±1% tolerance is required for precision current sensing applications or when tighter resistance accuracy is mandated by design specifications.

Both parts maintain identical mechanical compatibility, thermal performance, and safety certifications across the full operating temperature range of -55°C to 275°C.

Frequently Asked Questions (FAQ)

Q: Can S2-0R75F1 replace S2-0R75J8 in existing designs?
