Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROX1SJR47 is permissible when the alternative component meets the following critical parameters:

• Resistance Value: 470 mOhms exact match
• Tolerance: ±5% or tighter
• Power Rating: 1W minimum
• Composition: Metal Oxide Film
• Package Configuration: Axial through-hole
• Termination Count: 2 leads
• Regulatory Compliance: RoHS3 Compliant
• Operating Temperature: Minimum -55°C to +130°C range coverage

The substitute part RSF100JB-73-0R47 from YAGEO meets all mandatory electrical parameters and regulatory requirements. Physical dimensions vary slightly between manufacturers due to standard design tolerances in axial resistor construction. Both components share identical electrical performance characteristics within specified tolerance bands.

Engineering Selection Recommendations

Primary Selection: ROX1SJR47

The ROX1SJR47 from TE Connectivity Passive Product is the specified component with confirmed Active product status and full RoHS3 compliance. Current inventory of 1017 pieces supports immediate procurement. This component is suitable for all applications within the defined operating temperature range of -55°C to 130°C.

Substitute Selection: RSF100JB-73-0R47

The RSF100JB-73-0R47 from YAGEO is a qualified substitute meeting all mandatory electrical specifications. This component provides extended operating temperature capability to 235°C, which exceeds the primary part specification. RoHS3 compliance and REACH Unaffected status confirm regulatory alignment. Inventory availability of 4480 pieces supports high-volume requirements. Physical dimensions are within standard axial resistor manufacturing tolerances and do not impact circuit board layout for typical through-hole applications.

Both components are suitable for direct substitution in applications requiring 470 mOhms ±5% 1W axial resistors with metal oxide film construction and flame-proof characteristics.

Frequently Asked Questions (FAQ)

Q: Can RSF100JB-73-0R47 be used as a direct replacement for ROX1SJR47?

A: Yes. Both components share identical electrical specifications: 470 mOhms resistance, ±5% tolerance, 1W power rating, and metal oxide film composition. Both are RoHS3 compliant and feature flame-proof construction. Physical dimensions vary slightly due to standard manufacturing tolerances in axial resistor design, but both are compatible with standard through-hole circuit board layouts.

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

A: The ROX1SJR47 measures 0.138" diameter by 0.394" length (3.50mm x 10.00mm). The RSF100JB-73-0R47 measures 0.177" diameter by 0.453" length (4.50mm x 11.50mm). These variations are within standard axial resistor manufacturing tolerances and do not affect electrical performance or typical PCB mounting applications.

Q: Does the extended temperature range of RSF100JB-73-0R47 affect substitution suitability?

A: No. The RSF100JB-73-0R47 operating range of -55°C to 235°C exceeds the ROX1SJR47 specification of -55°C to 130°C. This extended capability does not compromise compatibility and provides additional design margin for applications operating at elevated temperatures.

Q: Are both components RoHS3 compliant?

A: Yes. Both ROX1SJR47 and RSF100JB-73-0R47 carry RoHS3 compliance certification, confirming conformance to restricted substance requirements.

Q: What is the temperature coefficient difference between these parts?

A: The ROX1SJR47 specifies a temperature coefficient of ±350ppm/°C. The RSF100JB-73-0R47 temperature coefficient is not provided in the available data. For applications requiring precise temperature coefficient matching, the primary part specification should be referenced.

Q: Can these components be used interchangeably in high-reliability applications?

A: Both components meet identical electrical and regulatory requirements for standard applications. Selection between them should be based on inventory availability, lead time, packaging requirements (Tape & Box versus Bulk), and specific application temperature operating points within their respective ranges.
