Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS005R1000FS73 is determined by strict alignment of the following parameters:

• Resistance value: 100 mOhms ±1%
• Power rating: 5W minimum
• Composition: Wirewound
• Package configuration: Axial through-hole
• Physical dimensions: 0.312" Dia × 0.875" L (7.92mm × 22.23mm)
• Operating temperature range: -65°C to +250°C
• Termination count: 2
• Moisture resistance capability

The RS005R1000FE73 qualifies as a parametric equivalent substitute. Both components share identical electrical specifications, mechanical dimensions, and environmental operating parameters. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. This packaging difference does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RS005R1000FS73 and RS005R1000FE73 are Active product status components manufactured by Vishay Dale within the RS series. Selection between these parts should be based on packaging requirements and compliance certifications applicable to the end application.

The RS005R1000FS73 carries RoHS non-compliant status and is REACH Affected. The RS005R1000FE73 is ROHS3 Compliant and REACH Unaffected, making it suitable for applications with regulatory compliance requirements under RoHS3 and REACH directives.

For applications without specific compliance mandates, either component provides equivalent electrical and mechanical performance. Packaging format selection (Tape & Reel versus Cut Tape) depends on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can RS005R1000FE73 be used as a direct replacement for RS005R1000FS73?

A: Yes. Both components share identical electrical specifications (100 mOhms ±1%, 5W), mechanical dimensions (0.312" Dia × 0.875" L), and operating temperature range (-65°C to +250°C). The only difference is packaging format: Tape & Reel versus Cut Tape. This does not affect circuit performance or board-level compatibility.

Q: What is the significance of the packaging format difference?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly processes. Cut Tape (CT) packaging is suitable for manual assembly or lower-volume production runs. The electrical and mechanical properties of the component remain unchanged regardless of packaging format.

Q: Are there compliance differences between these parts?

A: Yes. The RS005R1000FS73 is RoHS non-compliant and REACH Affected. The RS005R1000FE73 is ROHS3 Compliant and REACH Unaffected. Applications subject to RoHS3 or REACH regulations should specify the FE73 variant.

Q: Do these resistors maintain performance across the full operating temperature range?

A: Both components are rated for -65°C to +250°C operation. Electrical specifications remain valid across this entire range. Specific performance characteristics at temperature extremes should be confirmed against the manufacturer's detailed datasheet for the application.

Q: What is the moisture resistance feature?

A: Both components incorporate moisture-resistant construction, suitable for environments with elevated humidity or condensation exposure. This feature does not classify them as hermetically sealed; standard PCB-level moisture protection practices remain applicable.
