Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSF3JB22R0 are qualified based on the following critical parameters:

• Resistance value: 22 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The identified substitutes ROX3SJ22R and RSS3W22RJTB meet all core electrical and mechanical specifications. Variations in temperature coefficient, maximum operating temperature, physical dimensions, and packaging format are secondary parameters that do not prevent functional substitution in applications designed for the RSF3JB22R0.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RSF3JB22R0, ROX3SJ22R, and RSS3W22RJTB—are active products with ROHS3 compliance and meet the core electrical specifications of 22 Ohms, ±5% tolerance, and 3W power rating in metal oxide film axial package configuration.

ROX3SJ22R maintains the widest operating temperature range (-55°C ~ 200°C) among the substitutes and is available in higher inventory volume (11,249 pieces). This part is suitable for applications where the upper temperature limit of 200°C is acceptable.

RSS3W22RJTB operates within a narrower temperature range (-55°C ~ 155°C) and should be selected only when this temperature specification aligns with application requirements. The REACH status for this part is listed as vendor undefined, requiring clarification for applications subject to REACH compliance verification.

Physical dimension variations across the three parts are minor and typically do not impact PCB layout compatibility for standard through-hole designs, though board-level spacing constraints should be confirmed during design integration.

Frequently Asked Questions (FAQ)

Q: Can ROX3SJ22R be used as a direct replacement for RSF3JB22R0?

A: Yes. Both parts share identical electrical specifications: 22 Ohms, ±5% tolerance, 3W power rating, metal oxide film composition, and axial package type. The primary difference is the operating temperature range (200°C maximum for ROX3SJ22R versus 235°C for RSF3JB22R0). Substitution is valid for applications operating within -55°C to 200°C.

Q: What are the physical dimension differences between these parts?

A: RSF3JB22R0 measures 6.00mm diameter x 17.50mm length. ROX3SJ22R measures 5.50mm diameter x 16.00mm length. RSS3W22RJTB measures 5.00mm diameter x 15.00mm length. These variations are within typical tolerances for axial resistor designs and do not typically affect PCB footprint compatibility.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk, Cut Tape, or Tape & Box) affects only procurement, handling, and assembly processes. Electrical and thermal performance remain identical across all three parts.

Q: Which substitute part has the best inventory availability?

A: ROX3SJ22R has the highest inventory level at 11,249 pieces in stock, compared to 890 pieces for RSS3W22RJTB and 660 pieces for the main part RSF3JB22R0.

Q: Are all three parts RoHS compliant?

A: RSF3JB22R0 and ROX3SJ22R are confirmed ROHS3 compliant. RSS3W22RJTB is ROHS3 compliant, though REACH status is listed as vendor undefined and should be clarified for applications requiring full REACH compliance documentation.
