Engineering Selection Recommendations

The RS01A47R00FE70 is a direct electrical and mechanical equivalent to the RS01A47R00FS70. Selection between these parts should be based on the following factors:

Packaging Requirements: Choose RS01A47R00FS70 when Tape & Reel packaging is required for automated assembly processes. Select RS01A47R00FE70 when Cut Tape packaging is acceptable or preferred for manual assembly or lower-volume applications.

Compliance Requirements: The RS01A47R00FE70 carries ROHS3 compliance certification, while the RS01A47R00FS70 is RoHS non-compliant. Applications subject to RoHS regulations must use the RS01A47R00FE70. The RS01A47R00FS70 remains suitable for applications without RoHS compliance mandates.

REACH Status: The RS01A47R00FS70 is REACH Affected, while the RS01A47R00FE70 is REACH Unaffected. This distinction may influence selection for applications in regulated markets.

Both parts maintain identical electrical performance, temperature stability, and physical form factor, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RS01A47R00FE70 be used as a direct replacement for RS01A47R00FS70 in PCB assembly?

A: Yes. Both parts are electrically and mechanically identical. The RS01A47R00FE70 can be substituted directly. The only difference is packaging format: Tape & Reel versus Cut Tape. Verify that your assembly process can accommodate the Cut Tape format before substitution.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides the same components on shorter tape segments, typically used for manual assembly or lower-volume production runs.

Q: Are there compliance differences between these parts?

A: Yes. The RS01A47R00FE70 is ROHS3 compliant and REACH Unaffected, while the RS01A47R00FS70 is RoHS non-compliant and REACH Affected. For applications requiring RoHS compliance, the RS01A47R00FE70 must be used.

Q: Do these resistors have identical temperature performance?

A: Yes. Both parts share identical temperature coefficient (±20ppm/°C) and operating temperature range (-65°C to 250°C), ensuring equivalent thermal stability and performance across all operating conditions.

Q: Can I mix these parts in the same production batch?

A: Electrically and mechanically, yes. However, packaging format differences may require separate handling procedures. Verify assembly process compatibility with Cut Tape format before mixing parts in production.
