Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS01AR3000FS70 is determined by matching the following critical parameters:

• Resistance value: 300 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.094" Dia x 0.406" L (2.39mm x 10.31mm)
• Operating temperature range: -65°C to 250°C
• Termination count: 2

The RS01AR3000FE70 qualifies as a parametric equivalent. It maintains identical electrical specifications and mechanical dimensions but differs in packaging format (Cut Tape versus Tape & Reel) and compliance certifications. This distinction allows for direct functional substitution in applications where the packaging delivery method is flexible.

Engineering Selection Recommendations

The RS01AR3000FE70 serves as a direct functional substitute for the RS01AR3000FS70 in applications requiring identical electrical and mechanical performance. Selection between these parts should be based on:

• Packaging requirements: The FS70 variant is supplied in Tape & Reel format, suitable for automated assembly processes. The FE70 variant is supplied in Cut Tape format, appropriate for manual or semi-automated handling.
• Regulatory compliance: The FE70 achieves ROHS3 compliance and REACH unaffected status, whereas the FS70 is RoHS non-compliant and REACH affected. Applications subject to environmental or regulatory restrictions may require the FE70 variant.
• Inventory availability: The FE70 variant maintains higher stock levels (1639 units) compared to the FS70 (669 units), which may influence lead time considerations.

Both parts are active products from the same manufacturer and series, ensuring consistent quality and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RS01AR3000FE70 be used as a direct replacement for RS01AR3000FS70?

A: Yes. Both parts share identical electrical specifications (300 mOhms, ±1%, 1W), composition (wirewound), physical dimensions (0.094" Dia x 0.406" L), and operating temperature range (-65°C to 250°C). The primary difference is packaging format: FS70 is Tape & Reel, while FE70 is Cut Tape.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components in individual tape segments, typically used for manual assembly or lower-volume applications. Both formats contain the same component.

Q: Does the packaging format affect component performance?

A: No. The component itself is identical regardless of packaging format. Performance, electrical characteristics, and reliability remain unchanged between FS70 and FE70 variants.

Q: Why would I choose FE70 over FS70?

A: The FE70 variant offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to environmental regulations. Additionally, higher inventory availability may reduce lead times.

Q: Are there any mechanical compatibility issues when switching between these variants?

A: No. Both variants maintain the same axial package case, physical dimensions, and two-termination configuration. They are mechanically interchangeable in any circuit design or PCB layout.

Q: What certifications differ between these parts?

A: The FS70 is RoHS non-compliant and REACH affected. The FE70 is ROHS3 compliant and REACH unaffected. Both share the same ECCN (EAR99) and HTSUS (8533.21.0080) classifications.
