Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 41F2K2E is determined by the following critical parameters:

• Resistance Value: 2.2 kOhms (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)

The RS01A2K200FE70 manufactured by Vishay Dale meets all critical electrical and mechanical parameters. Both parts are wirewound axial resistors with identical resistance, tolerance, power rating, and temperature coefficient specifications. Physical dimensions vary slightly, but both conform to standard axial package dimensions suitable for through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 41F2K2E and RS01A2K200FE70 are active production parts with full RoHS compliance. The 41F2K2E offers a wider operating temperature range (-55°C to 275°C) compared to the RS01A2K200FE70 (-65°C to 250°C). Selection between these parts should be based on the specific operating temperature requirements of the application. The RS01A2K200FE70 includes moisture-resistant construction, which may provide additional environmental protection in humid or corrosive conditions. Physical dimensions differ slightly; PCB layout and mechanical clearance constraints should be evaluated during component placement design.

Frequently Asked Questions (FAQ)

Q: Can RS01A2K200FE70 be used as a direct replacement for 41F2K2E?

A: Yes, the RS01A2K200FE70 meets all critical electrical specifications: 2.2 kOhms resistance, ±1% tolerance, 1W power rating, wirewound composition, and ±20ppm/°C temperature coefficient. Both are axial through-hole packages suitable for identical PCB footprints. Physical dimensions vary slightly, but both conform to standard axial resistor dimensions.

Q: What is the difference in operating temperature range?

A: The 41F2K2E operates from -55°C to 275°C, while the RS01A2K200FE70 operates from -65°C to 250°C. Applications requiring operation above 250°C must use the 41F2K2E. Applications requiring operation below -55°C can use either part, though the RS01A2K200FE70 extends to -65°C.

Q: Does the moisture-resistant feature of RS01A2K200FE70 affect electrical performance?

A: No. Moisture resistance is an environmental protection feature that does not alter the electrical characteristics. Both parts maintain identical resistance, tolerance, temperature coefficient, and power rating specifications.

Q: Are there packaging considerations when switching between these parts?

A: The 41F2K2E is supplied in box packaging, while the RS01A2K200FE70 is supplied in cut tape format. This affects inventory management and automated assembly processes but does not impact electrical or mechanical compatibility on the PCB.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. The 41F2K2E is RoHS Compliant, and the RS01A2K200FE70 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions for electronic components.
