Key Parameters

Substitute Part Grouping Explanation

The RS00547K00FE73 qualifies as a direct substitute for the RS00547K00FS73 based on identical electrical and mechanical parameters. Both parts share the same resistance value (47 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 lies in packaging format: RS00547K00FS73 is supplied in tape and reel (TR) format, while RS00547K00FE73 is supplied in cut tape (CT) format. Both parts maintain the same series designation (RS) and active product status.

Parameter Comparison

Engineering Selection Recommendations

Selection between RS00547K00FS73 and RS00547K00FE73 depends on packaging requirements and regulatory compliance needs. The RS00547K00FS73 in tape and reel format is suitable for high-volume automated assembly processes. The RS00547K00FE73 in cut tape format accommodates lower-volume applications or manual assembly workflows. For applications requiring ROHS3 compliance and REACH unaffected status, the RS00547K00FE73 is the appropriate choice. Both parts maintain identical electrical performance and physical dimensions, ensuring functional interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RS00547K00FE73 replace RS00547K00FS73 in my circuit design? A: Yes. Both parts are electrically and mechanically identical with the same 47 kOhms resistance, ±1% tolerance, 5W power rating, and axial configuration. The only difference is packaging format (cut tape versus tape and reel).

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging? A: Tape and reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly. Cut tape packaging supplies components on individual tape segments, suitable for manual assembly or lower-volume production runs.

Q: Does the packaging format affect the component's electrical performance? A: No. The electrical and thermal characteristics remain identical regardless of packaging format. Only the delivery and handling method differs.

Q: Why does RS00547K00FE73 have different RoHS and REACH status? A: RoHS and REACH compliance status reflects the manufacturing process and material sourcing at the time of production. RS00547K00FE73 meets ROHS3 compliance and is REACH unaffected, making it suitable for applications with strict regulatory requirements.

Q: Are both parts currently available? A: Yes. RS00547K00FS73 has 1133 units in stock, and RS00547K00FE73 has 1072 units in stock, both listed as active products.
