Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF200JB-73-8R2 is determined by the following critical parameters:

• Resistance value: 8.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package: Axial through-hole (exact match required)
• Power rating: 2W minimum (equal or higher acceptable)
• Operating temperature range: Must encompass or match the original specification
• Compliance: ROHS3 and REACH status alignment

The substitute parts ROX3SJ8R2 and ROX2SJ8R2 meet these criteria. ROX3SJ8R2 provides a higher power rating (3W) while maintaining all other electrical parameters. ROX2SJ8R2 matches the 2W power rating exactly and is the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

ROX2SJ8R2 is the manufacturer-recommended direct equivalent. It maintains identical electrical specifications (8.2 Ohms, ±5%, 2W) and composition while offering enhanced pulse-withstanding capability. This part is ROHS3 compliant and widely available (13,696 units in stock). The operating temperature range is -55°C to 200°C, which covers standard industrial applications. Use this part for direct replacement in standard circuit designs.

ROX3SJ8R2 is an upgrade option providing increased power dissipation capability (3W versus 2W). This part is suitable for applications requiring thermal margin or higher transient power handling. It maintains all other electrical parameters and is ROHS3 compliant with REACH Unaffected status. The operating temperature range is -55°C to 200°C. Select this part when circuit analysis indicates potential thermal stress or when design margins require higher power rating.

Both substitute parts are active products with established supply chains and comply with ROHS3 requirements. Selection between ROX2SJ8R2 and ROX3SJ8R2 depends on application power dissipation requirements and thermal design considerations.

Frequently Asked Questions (FAQ)

Q: Can ROX2SJ8R2 be used as a direct replacement for RSF200JB-73-8R2?

A: Yes. ROX2SJ8R2 matches the critical electrical parameters: 8.2 Ohms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and axial package. Both are ROHS3 compliant. This is the manufacturer-recommended equivalent.

Q: What is the difference between ROX2SJ8R2 and ROX3SJ8R2?

A: The primary difference is power rating: ROX2SJ8R2 is rated 2W (matching the original), while ROX3SJ8R2 is rated 3W. Both share identical resistance, tolerance, composition, and package specifications. ROX3SJ8R2 provides additional thermal headroom for applications with higher power dissipation.

Q: Are there physical size differences between these parts?

A: Yes. RSF200JB-73-8R2 measures 0.197" Dia × 0.610" L (5.00mm × 15.50mm). ROX2SJ8R2 measures 0.197" Dia × 0.472" L (5.00mm × 12.00mm). ROX3SJ8R2 measures 0.217" Dia × 0.630" L (5.50mm × 16.00mm). All are axial through-hole packages with compatible PCB footprints for standard 0.1" pitch designs.

Q: What is the operating temperature difference?

A: RSF200JB-73-8R2 operates from -55°C to 235°C. Both ROX2SJ8R2 and ROX3SJ8R2 operate from -55°C to 200°C. For applications requiring operation above 200°C, the original RSF200JB-73-8R2 is required.

Q: Are packaging formats compatible?

A: RSF200JB-73-8R2 is supplied in Bulk packaging. ROX2SJ8R2 and ROX3SJ8R2 are supplied in Cut Tape (CT) format. Both formats are compatible with standard PCB assembly processes. Tape format may offer advantages for automated assembly workflows.

Q: Do these parts have different compliance certifications?

A: All three parts are ROHS3 compliant. RSF200JB-73-8R2 and ROX3SJ8R2 have REACH Unaffected status. ROX2SJ8R2 has Vendor Undefined REACH status. For applications with strict REACH requirements, ROX3SJ8R2 is the preferred substitute.
