Parameter Comparison

Engineering Selection Recommendations

RS01AR5000FE70 (Vishay Dale): This part is electrically and mechanically identical to the main part RS01AR5000FS70, with identical dimensions and specifications. The primary distinction is RoHS3 compliance status and REACH unaffected classification, compared to the main part's RoHS non-compliant status. Selection of this substitute is appropriate for applications requiring RoHS3 compliance.

41FR50 (Ohmite): This part meets all critical electrical specifications and operates within the same tolerance and temperature coefficient parameters. The Ohmicone® 40 series designation indicates a different product line. Physical dimensions are larger (0.126" Dia x 0.437" L versus 0.094" Dia x 0.406" L), which may affect PCB layout compatibility in space-constrained designs. This substitute is suitable for applications where dimensional differences do not present mechanical constraints. RoHS compliance status matches the main part.

Frequently Asked Questions (FAQ)

Q: Can RS01AR5000FE70 be used as a direct replacement for RS01AR5000FS70?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications, tolerance, power rating, temperature coefficient, and operating temperature range. Dimensions are identical. The primary difference is RoHS3 compliance status of the FE70 variant.

Q: What are the dimensional differences between RS01AR5000FS70 and 41FR50?

A: RS01AR5000FS70 measures 0.094" diameter by 0.406" length. The 41FR50 measures 0.126" diameter by 0.437" length. Both are axial package configurations. Verify PCB layout clearances before substitution.

Q: Are all three parts electrically equivalent?

A: Yes. All three parts share identical resistance (500 mOhms), tolerance (±1%), power rating (1W), composition (wirewound), and temperature coefficient (±90ppm/°C). Electrical performance in circuit applications is equivalent.

Q: Does the 41FR50 have a specified operating temperature range?

A: The operating temperature range is not provided in the available specifications for the 41FR50. The RS01AR5000FS70 and RS01AR5000FE70 both specify -65°C ~ 250°C.

Q: Which substitute should be selected for RoHS-compliant applications?

A: RS01AR5000FE70 is RoHS3 compliant and REACH unaffected, making it suitable for applications with RoHS compliance requirements.
