Key Parameters

Substitute Part Grouping Explanation

The S5-100RF2 qualifies as a substitute for the S5-100RJ2 based on the following critical parameters:

• Resistance Value: Both parts are 100 Ohms
• Power Rating: Both rated at 4W
• Package / Case: Both use 8230 J-Lead package
• Physical Dimensions: Identical footprint (0.819" L x 0.296" W, 20.80mm x 7.50mm)
• Height - Seated: Both maximum 0.319" (8.10mm)
• Operating Temperature Range: Both -55°C ~ 275°C
• Temperature Coefficient: Both ±20ppm/°C
• Composition: Both wirewound
• RoHS Status: Both ROHS3 Compliant
• Moisture Sensitivity Level: Both MSL 1 (Unlimited)

The primary difference is tolerance specification: S5-100RF2 provides ±1% tolerance versus the ±5% tolerance of S5-100RJ2. This represents an upgrade in precision while maintaining full mechanical and thermal compatibility.
