Substitute Part Grouping Explanation

Substitution eligibility for the 41F47RE is determined by matching the following critical parameters:

• Resistance Value: 47 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Temperature Coefficient: ±20ppm/°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant (minimum requirement)

The RS01A47R00FE70 manufactured by Vishay Dale meets all substitution criteria. Both components share identical electrical specifications and axial package configuration, enabling direct functional replacement in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the RS01A47R00FE70 directly replace the 41F47RE in existing designs?

A: Yes. Both components share identical electrical specifications (47 Ohms, ±1%, 1W, ±20ppm/°C) and axial package configuration, enabling direct functional replacement without circuit modification.

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

A: Bulk packaging supplies loose components, while Cut Tape packaging provides components on continuous tape for automated assembly equipment. Selection depends on assembly process requirements and handling procedures.

Q: Does the moisture-resistant feature of the RS01A47R00FE70 affect electrical performance?

A: No. Moisture resistance is an additional feature that enhances reliability in humid environments without altering the electrical characteristics specified for both components.

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

A: The RS01A47R00FE70 specifies an operating temperature range of -65°C to 250°C. The 41F47RE does not specify an operating temperature range in the provided data. Verify temperature requirements against application specifications before selection.

Q: Do both components meet current regulatory compliance standards?

A: Yes. Both the 41F47RE and RS01A47R00FE70 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
