Substitute Part Grouping Explanation

Substitution for the RS005100R0FS73 is determined by strict equivalence across the following critical parameters: resistance value (100 Ohms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), operating temperature range (-65°C to 250°C), and physical dimensions (0.312" Dia x 0.875" L). The substitute part RS005100R0FE73 meets all these electrical and mechanical specifications, making it a direct parametric equivalent. Differences in RoHS compliance status and REACH classification do not affect functional interchangeability but may influence procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The RS005100R0FE73 serves as a direct parametric equivalent to the RS005100R0FS73 across all electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements. The RS005100R0FE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to these regulatory frameworks. The RS005100R0FS73 remains appropriate for applications without such compliance mandates. Both parts maintain identical functional performance, temperature characteristics, and physical form factor, ensuring interchangeability in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Are RS005100R0FS73 and RS005100R0FE73 electrically identical? A: Yes. Both parts share identical resistance (100 Ohms), tolerance (±1%), power rating (5W), temperature coefficient (±20ppm/°C), and operating temperature range (-65°C to 250°C).

Q: What is the difference between these two parts? A: The primary differences are RoHS compliance status and REACH classification. RS005100R0FE73 is ROHS3 compliant and REACH unaffected, while RS005100R0FS73 is RoHS non-compliant and REACH affected. Functionally and mechanically, they are equivalent.

Q: Can I use RS005100R0FE73 as a direct replacement for RS005100R0FS73? A: Yes, from an electrical and mechanical standpoint. Verify that your application's regulatory requirements align with the compliance status of the selected part.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.312" Dia x 0.875" L (7.92mm x 22.23mm) and use the same axial package type.

Q: Which part should I choose for new designs? A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance or REACH unaffected status, use RS005100R0FE73. For applications without these constraints, either part is suitable based on availability and cost considerations.
