Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF3JB22K0 is determined by the following critical parameters:

• Resistance value: 22 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Compliance: ROHS3 Compliant

The ROX3SJ22K meets all primary electrical specifications and maintains mechanical compatibility through identical axial packaging. Both parts share the same resistance, tolerance, power rating, and composition. Compliance certifications align, with both parts rated ROHS3 Compliant and assigned identical HTSUS and ECCN classifications.

Parameter Comparison

Engineering Selection Recommendations

The ROX3SJ22K qualifies as a direct substitute for the RSF3JB22K0 based on matching electrical specifications and compliance certifications. Both parts are ROHS3 Compliant and carry identical trade classification codes.

When selecting between these parts, consider the following provided specifications:

• The RSF3JB22K0 operates to 235°C maximum, while the ROX3SJ22K operates to 200°C maximum. Applications requiring operation above 200°C require the RSF3JB22K0.
• The RSF3JB22K0 maintains a temperature coefficient of ±200ppm/°C compared to the ROX3SJ22K at ±350ppm/°C. Applications with strict temperature stability requirements favor the RSF3JB22K0.
• Both parts feature metal oxide film construction with safety design. The RSF3JB22K0 specifies flame retardant coating; the ROX3SJ22K specifies flame proof and pulse withstanding characteristics.
• Packaging format differs: RSF3JB22K0 is supplied in bulk; ROX3SJ22K is supplied in cut tape format.

Frequently Asked Questions (FAQ)

Q: Can ROX3SJ22K replace RSF3JB22K0 in all applications?

A: ROX3SJ22K is electrically and mechanically compatible for applications operating within -55°C to 200°C. Applications requiring operation above 200°C or demanding temperature coefficient stability better than ±350ppm/°C require the RSF3JB22K0.

Q: What are the physical dimension differences?

A: RSF3JB22K0 measures 0.236" diameter × 0.689" length (6.00mm × 17.50mm). ROX3SJ22K measures 0.217" diameter × 0.630" length (5.50mm × 16.00mm). Both fit standard axial through-hole footprints, though the ROX3SJ22K is slightly more compact.

Q: Are both parts RoHS compliant?

A: Both RSF3JB22K0 and ROX3SJ22K are ROHS3 Compliant.

Q: What is the difference between flame retardant and flame proof coatings?

A: This distinction is provided in the manufacturer specifications. RSF3JB22K0 features flame retardant coating; ROX3SJ22K features flame proof coating. Application requirements determine which coating specification is necessary.

Q: How do temperature coefficients affect circuit performance?

A: Temperature coefficient defines resistance change per degree Celsius. RSF3JB22K0 at ±200ppm/°C exhibits tighter tolerance to temperature variation than ROX3SJ22K at ±350ppm/°C. High-precision circuits benefit from lower temperature coefficient values.
