Substitute Part Grouping Explanation

Substitution eligibility for the RS00522R00FS73 is determined by the following critical parameters:

• Resistance value: 22 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Operating temperature range: -65°C to 250°C (exact match required)
• Physical dimensions: 0.312" Dia x 0.875" L (exact match required)
• Moisture resistance: Required feature (exact match required)

The identified substitute part RS00522R00FE73 meets all electrical and mechanical criteria. The primary difference between the main part and substitute is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both formats contain identical components with no functional or performance differences.

Parameter Comparison

Engineering Selection Recommendations

Both RS00522R00FS73 and RS00522R00FE73 are functionally equivalent and electrically interchangeable for all circuit applications requiring a 22 Ohm, 5W wirewound axial resistor with ±1% tolerance and moisture resistance.

Selection between these parts should be based on:

• Packaging format requirements: Choose RS00522R00FS73 for automated assembly processes requiring Tape & Reel format. Choose RS00522R00FE73 for manual assembly or applications where Cut Tape format is acceptable.
• Compliance requirements: RS00522R00FE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental regulations. RS00522R00FS73 is RoHS non-compliant and REACH affected.
• Inventory availability: RS00522R00FE73 has higher stock availability (1212 units) compared to RS00522R00FS73 (768 units).

Both parts share identical electrical performance, temperature characteristics, and physical dimensions, ensuring direct substitution without circuit redesign or performance impact.

Frequently Asked Questions (FAQ)

Q: Can RS00522R00FE73 be used as a direct replacement for RS00522R00FS73 in production assembly?

A: Yes, RS00522R00FE73 is electrically and mechanically equivalent. The primary consideration is packaging format compatibility. If your assembly process requires Tape & Reel format, use RS00522R00FS73. If Cut Tape format is acceptable, RS00522R00FE73 is a direct substitute.

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

A: Tape & Reel (TR) format supplies components on continuous tape wound on a reel, suitable for high-speed automated pick-and-place assembly. Cut Tape (CT) format supplies components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume production. The components themselves are identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical resistance values (22 Ohms), tolerance (±1%), power rating (5W), temperature coefficient (±20ppm/°C), and operating temperature range (-65°C to 250°C). They are fully interchangeable from an electrical standpoint.

Q: What is the significance of RoHS and REACH compliance differences?

A: RS00522R00FE73 is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to environmental regulations in the European Union and other regions with similar requirements. RS00522R00FS73 is RoHS non-compliant and REACH affected. Select based on your application's regulatory requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts have identical operating temperature ranges (-65°C to 250°C) and temperature coefficients (±20ppm/°C), making them fully interchangeable for high-temperature circuit applications.

Q: Which part should I choose if compliance is not a concern?

A: If compliance is not a requirement, selection can be based on packaging format preference and inventory availability. RS00522R00FE73 has higher stock availability (1212 units versus 768 units).
