Key Parameters

Substitute Part Grouping Explanation

Substitution for the RS01AR2000FS70 is determined by the following critical parameters that must remain constant:

• Resistance value: 200 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 ~ 250°C
• Number of terminations: 2

The primary difference between the main part and its substitute is the packaging format. The RS01AR2000FS70 is supplied in tape and reel (TR) format, while the RS01AR2000FE70 is supplied in cut tape (CT) format. Both parts are identical in electrical and mechanical specifications, allowing direct substitution based on packaging requirements.

Parameter Comparison

Engineering Selection Recommendations

The RS01AR2000FE70 serves as a direct electrical and mechanical substitute for the RS01AR2000FS70. Selection between these parts should be based on the following criteria:

Packaging Format: Choose RS01AR2000FS70 when tape and reel packaging is required for automated assembly processes. Select RS01AR2000FE70 when cut tape packaging is acceptable or preferred for manual assembly or lower-volume applications.

Compliance Requirements: The RS01AR2000FE70 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental and regulatory requirements. The RS01AR2000FS70 is RoHS non-compliant and REACH affected, requiring evaluation against specific application compliance mandates.

Availability: The RS01AR2000FE70 has higher inventory availability (1411 units) compared to the RS01AR2000FS70 (932 units), which may influence lead time considerations.

Both parts are active products with identical electrical performance, thermal characteristics, and mechanical dimensions, ensuring functional interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RS01AR2000FE70 be used as a direct replacement for RS01AR2000FS70?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values (200 mOhms), tolerance (±1%), power rating (1W), physical dimensions (0.094" Dia x 0.406" L), and operating temperature range (-65°C ~ 250°C). The only difference is packaging format: tape and reel versus cut tape.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape packaging supplies components on individual tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Are there compliance differences between these parts?

A: Yes. The RS01AR2000FE70 is ROHS3 compliant and REACH unaffected, while the RS01AR2000FS70 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations should specify the RS01AR2000FE70.

Q: Do these parts have identical thermal performance?

A: Yes. Both parts operate across the same temperature range (-65°C ~ 250°C) and are rated for 1W power dissipation with identical wirewound composition and moisture-resistant features.

Q: Which part should be selected for high-volume automated assembly?

A: The RS01AR2000FS70 in tape and reel format is optimized for automated assembly processes. However, if compliance certifications are required, the RS01AR2000FE70 should be evaluated for compatibility with your assembly equipment.
