Key Parameters

Substitute Part Grouping Explanation

Substitution for the RSF3JB10R0 is determined by strict equivalence in the following electrical and mechanical parameters:

• Resistance value: 10 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package: Axial through-hole (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The substitute part ROX3SJ10R, manufactured by TE Connectivity Passive Product, meets all these core electrical and mechanical criteria. Variations in physical dimensions, temperature coefficient, and maximum operating temperature are within acceptable ranges for this component category and do not prevent functional substitution.

Engineering Selection Recommendations

Both the RSF3JB10R0 and ROX3SJ10R are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Circuit board layout constraints: The ROX3SJ10R has slightly smaller physical dimensions (5.50mm diameter vs. 6.00mm, 16.00mm length vs. 17.50mm), which may be advantageous in space-constrained applications.
• Temperature stability requirements: The RSF3JB10R0 offers superior temperature coefficient performance (±200ppm/°C vs. ±350ppm/°C), suitable for precision applications requiring tighter stability across temperature ranges.
• Maximum operating temperature: The RSF3JB10R0 supports operation up to 235°C, compared to 200°C for the ROX3SJ10R. Applications requiring extended high-temperature operation should specify the RSF3JB10R0.
• Availability and supply chain: The ROX3SJ10R has significantly higher inventory availability (34,937 pieces vs. 666 pieces).

Frequently Asked Questions (FAQ)

Q: Can ROX3SJ10R be used as a direct replacement for RSF3JB10R0 in all applications?

A: ROX3SJ10R is electrically equivalent for resistance, tolerance, and power rating. However, verify that your application does not require the extended temperature range (up to 235°C) or the tighter temperature coefficient (±200ppm/°C) of the RSF3JB10R0. Physical dimensions are slightly different; confirm PCB layout compatibility.

Q: What is the significance of the different temperature coefficients?

A: Temperature coefficient indicates how much the resistance value changes with temperature. The RSF3JB10R0 (±200ppm/°C) maintains more stable resistance across temperature variations compared to ROX3SJ10R (±350ppm/°C). For precision circuits, the lower coefficient is preferable.

Q: Are both parts suitable for high-temperature applications?

A: The RSF3JB10R0 operates up to 235°C, while ROX3SJ10R operates up to 200°C. For applications exceeding 200°C, the RSF3JB10R0 is required.

Q: Do the physical dimension differences affect PCB design?

A: Yes. The ROX3SJ10R is slightly smaller (5.50mm diameter, 16.00mm length) compared to RSF3JB10R0 (6.00mm diameter, 17.50mm length). Verify that your PCB footprint and component spacing accommodate the substitute part's dimensions.

Q: Are both parts RoHS compliant?

A: Yes, both RSF3JB10R0 and ROX3SJ10R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
