Substitute Part Grouping Explanation

Substitution eligibility for the RS01A2R700FS70 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.7 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 250°C
• Package type: Axial
• Physical dimensions: 0.094" Dia × 0.406" L
• Number of terminations: 2
• Moisture resistance feature

The RS01A2R700FE70 meets all electrical and mechanical requirements for direct substitution. The primary difference between the main part and its substitute is the packaging format: the main part is supplied in tape and reel (TR) configuration, while the substitute is available in cut tape (CT) format. Both parts are manufactured by Vishay Dale within the RS series and maintain identical performance characteristics across all specified parameters.

Engineering Selection Recommendations

Both the RS01A2R700FS70 and RS01A2R700FE70 are electrically and mechanically equivalent and suitable for direct substitution in circuit applications. Selection between these parts should be based on the following factors:

Packaging Requirements: The RS01A2R700FS70 is supplied in tape and reel format, suitable for automated assembly processes. The RS01A2R700FE70 is supplied in cut tape format, appropriate for manual assembly or lower-volume production runs.

Compliance Status: The RS01A2R700FE70 carries ROHS3 compliance certification, while the RS01A2R700FS70 is RoHS non-compliant. Applications subject to RoHS regulations should specify the RS01A2R700FE70.

Inventory Availability: The RS01A2R700FE70 has higher current stock levels (1760 units) compared to the RS01A2R700FS70 (651 units), which may influence lead time and procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can RS01A2R700FE70 be used as a direct replacement for RS01A2R700FS70 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The only differences are packaging format and RoHS compliance status.

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 applications. Both formats contain the same component.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical electrical specifications: 2.7 Ohms resistance, ±1% tolerance, 1W power rating, ±50ppm/°C temperature coefficient, and -65°C to 250°C operating temperature range.

Q: Which part should be selected for RoHS-regulated applications?

A: The RS01A2R700FE70 is ROHS3 compliant and should be specified for applications subject to RoHS directives. The RS01A2R700FS70 is RoHS non-compliant.

Q: Do both parts have the same physical dimensions?

A: Yes. Both parts are axial package type with identical dimensions of 0.094" diameter by 0.406" length (2.39mm × 10.31mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have moisture sensitivity level classified as Not Applicable, indicating they are not subject to moisture-related handling restrictions during storage and assembly.
