Substitute Part Grouping Explanation

The RS00539K00FE73 qualifies as a direct substitute for the RS00539K00FS73 based on identical electrical and mechanical parameters. Both parts share the same resistance value (39 kOhms), tolerance (±1%), power rating (5W), composition (wirewound), temperature coefficient (±20ppm/°C), operating temperature range (-65°C to 250°C), physical dimensions (0.312" Dia x 0.875" L), and axial package configuration. The primary difference between these parts is packaging format: the main part uses Tape & Reel (TR) while the substitute uses Cut Tape (CT). Both maintain the same series designation (RS) and active product status. This substitution is valid for applications where packaging format flexibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The RS00539K00FE73 serves as a functional equivalent to the RS00539K00FS73 for applications requiring identical electrical performance and mechanical fit. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The RS00539K00FE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with stricter environmental regulations. The RS00539K00FS73 remains appropriate for applications where RoHS non-compliance is acceptable and Tape & Reel packaging is preferred for automated assembly processes. Both parts maintain active production status and identical performance specifications across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RS00539K00FE73 replace RS00539K00FS73 in my circuit?

A: Yes. Both parts are electrically and mechanically identical with 39 kOhms resistance, ±1% tolerance, 5W power rating, and identical temperature coefficients and operating ranges. The only difference is packaging format (Cut Tape versus Tape & Reel).

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging provides components on tape segments, suitable for lower-volume applications or manual assembly processes. Both formats contain identical components.

Q: Are there compliance differences between these parts?

A: Yes. The RS00539K00FE73 is ROHS3 compliant and REACH unaffected, while the RS00539K00FS73 is RoHS non-compliant and REACH affected. Select based on your application's regulatory requirements.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.312" diameter by 0.875" length (7.92mm x 22.23mm) and use identical axial package configuration, ensuring mechanical compatibility in PCB layouts.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±20ppm/°C, ensuring stable resistance performance across the -65°C to 250°C operating range.
