Substitute Part Grouping Explanation

The S3-100RF1 qualifies as a substitute for the S3-100RJ8 based on the following criteria:

Identical Parameters:

• Resistance value: 100 Ohms
• Power rating: 3W
• Package / Case: 6327 J-Lead
• Physical dimensions: 0.626" L x 0.272" W (15.90mm x 6.90mm)
• Height - Seated (Max): 0.268" (6.80mm)
• Operating temperature range: -55°C ~ 275°C
• Temperature coefficient: ±20ppm/°C
• Composition: Wirewound
• Features: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Manufacturer: Riedon
• Series: S
• Product Status: Active

Tolerance Difference: The S3-100RF1 provides ±1% tolerance compared to the S3-100RJ8's ±5% tolerance. This represents an upgrade in precision while maintaining all other electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the S3-100RJ8 and S3-100RF1 are Active status components manufactured by Riedon with identical ROHS3 compliance and regulatory certifications. The S3-100RF1 provides enhanced tolerance specification (±1% versus ±5%) while maintaining full mechanical and thermal compatibility through the 6327 J-Lead package format.

Selection between these parts depends on application tolerance requirements. The S3-100RJ8 is suitable for applications where ±5% tolerance meets circuit specifications. The S3-100RF1 is appropriate for applications requiring tighter tolerance control without any package or thermal redesign.

Frequently Asked Questions (FAQ)

Q: Can S3-100RF1 directly replace S3-100RJ8 in existing designs?

A: Yes. Both parts share identical package dimensions (6327 J-Lead), physical footprint (0.626" L x 0.272" W), and thermal operating range (-55°C ~ 275°C). Direct substitution is mechanically and thermally compatible.
