RS01A100R0FS70 Equivalent & Substitute Parts

Part Overview

The RS01A100R0FS70 is a 100 Ohms ±1% 1W through-hole resistor with axial leads, manufactured by Vishay Dale. This wirewound resistor features moisture-resistant construction and operates across a wide temperature range from -65°C to 250°C. The component is currently in active production status. Identifying equivalent substitute parts is necessary to ensure design flexibility, optimize inventory management, and maintain supply chain continuity when the primary part number becomes unavailable or when alternative compliance certifications are required.

Substitute Part Grouping Explanation

Substitute parts for the RS01A100R0FS70 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

• Resistance value: 100 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.094" Dia x 0.406" L (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Operating temperature range: -65°C ~ 250°C (exact match required)
• Features: Moisture Resistant (exact match required)

The RS01A100R0FE70 meets all these criteria and qualifies as a direct substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the RS01A100R0FS70 and RS01A100R0FE70 are active production components from Vishay Dale with identical electrical and mechanical specifications. The primary distinction between these parts lies in their regulatory compliance status:

The RS01A100R0FS70 is RoHS non-compliant and REACH Affected. The RS01A100R0FE70 is ROHS3 Compliant and REACH Unaffected. Selection between these parts should be based on the regulatory requirements of the end application and target market. Applications requiring RoHS3 compliance should specify the RS01A100R0FE70. Applications without RoHS compliance requirements may use either part interchangeably from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can RS01A100R0FE70 be used as a direct replacement for RS01A100R0FS70?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (100 Ohms), tolerance (±1%), power rating (1W), wirewound composition, axial package type, physical dimensions, temperature coefficient, and operating temperature range. The difference is regulatory compliance status only.

Q: What is the difference between these two part numbers?

A: The RS01A100R0FS70 is RoHS non-compliant and REACH Affected. The RS01A100R0FE70 is ROHS3 Compliant and REACH Unaffected. All other specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.094" Dia x 0.406" L (2.39mm x 10.31mm) and use the same axial package type. They are mechanically interchangeable.

Q: Do these parts have the same temperature operating range?

A: Yes. Both parts operate from -65°C to 250°C with a temperature coefficient of ±20ppm/°C.

Q: Which part should I select for my application?

A: If your application or target market requires RoHS3 compliance, select RS01A100R0FE70. If RoHS compliance is not required, either part may be used. Both are in active production and available in inventory.
