Substitute Part Grouping Explanation

Substitution eligibility for the RS00510R00FS73 is determined by strict equivalence across the following parameters:

• Resistance value: 10 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -65°C to 250°C
• Physical dimensions: 0.312" Dia × 0.875" L
• Moisture-resistant feature requirement

The RS00510R00FE73 meets all electrical and mechanical specifications required for direct substitution. Differences in RoHS compliance status and REACH classification do not affect functional equivalence but may influence procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both RS00510R00FS73 and RS00510R00FE73 are functionally equivalent for circuit applications requiring 10 Ohm, 5W wirewound resistors with axial packaging. Selection between these parts should be based on regulatory compliance requirements:

The RS00510R00FE73 is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union environmental regulations. The RS00510R00FS73 remains a valid choice for applications without RoHS or REACH compliance mandates. Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. Inventory availability differs, with RS00510R00FE73 offering higher stock levels at 2,030 units compared to 1,424 units for RS00510R00FS73.

Frequently Asked Questions (FAQ)

Q: Can RS00510R00FE73 replace RS00510R00FS73 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The RS00510R00FE73 can be used as a direct substitute without circuit modifications or re-qualification.

Q: What is the difference between these two part numbers?

A: The primary differences are RoHS compliance status and REACH classification. RS00510R00FE73 is ROHS3 compliant and REACH unaffected, while RS00510R00FS73 is RoHS non-compliant and REACH affected. Electrical specifications, power rating, tolerance, temperature range, and physical dimensions are identical.

Q: Are there any thermal or performance differences?

A: No. Both parts have identical temperature coefficients (±20ppm/°C), operating temperature ranges (-65°C to 250°C), and power dissipation characteristics (5W).

Q: Does packaging differ between these parts?

A: No. Both parts are supplied in Cut Tape (CT) packaging with identical axial dimensions of 0.312" Dia × 0.875" L (7.92mm × 22.23mm).

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS or REACH regulations, RS00510R00FE73 is the appropriate choice. For applications without such requirements, either part is suitable based on availability and procurement preferences.
