Key Parameters

Substitute Part Grouping Explanation

The RS01A1R000FS70 qualifies as a substitute for the CW0011R000JS70 based on the following critical parameters:

Matching Parameters:

• Resistance value: 1 Ohms (identical)
• Composition: Wirewound (identical)
• Package / Case: Axial (identical)
• Physical dimensions: 0.094" Dia x 0.406" L (identical)
• Number of Terminations: 2 (identical)
• Features: Moisture Resistant (identical)
• Temperature Coefficient: ±50ppm/°C (identical)
• Manufacturer: Vishay Dale (same manufacturer)
• Product Status: Active (both in production)

Enhanced Specifications in Substitute:

• Tolerance: ±1% (improved from ±5%)
• Power Rating: 1W (specified, versus unspecified in main part)
• Operating Temperature Range: -65°C ~ 250°C (subset of main part range)

The substitute part maintains all critical mechanical and electrical compatibility parameters while offering tighter tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CW0011R000JS70 and RS01A1R000FS70 are active production components from Vishay Dale with identical mechanical compatibility and core electrical characteristics. Selection between these parts is determined by application-specific requirements:

Select CW0011R000JS70 when:

• Operating temperature requirements exceed 250°C
• Tolerance specification of ±5% is acceptable
• Packaging in Tape & Reel format is required

Select RS01A1R000FS70 when:

• Tighter tolerance of ±1% is required
• Power dissipation specification of 1W is needed
• Operating temperature range of -65°C to 250°C is sufficient
• Cut Tape packaging is acceptable

Both parts maintain RoHS non-compliant status and identical compliance classifications (ECCN: EAR99, HTSUS: 8533.21.0080).

Frequently Asked Questions (FAQ)

Q: Can RS01A1R000FS70 be used as a direct replacement for CW0011R000JS70?

A: Yes, for applications operating within -65°C to 250°C. The substitute maintains identical resistance value, physical dimensions, axial package configuration, and moisture-resistant wirewound construction. The primary differences are improved tolerance (±1% versus ±5%) and specified 1W power rating.

Q: What is the impact of the operating temperature range difference?

A: The CW0011R000JS70 operates to 350°C, while RS01A1R000FS70 operates to 250°C. If your application requires operation above 250°C, the CW0011R000JS70 is the only suitable option. For applications below 250°C, both parts are compatible.

Q: Does the packaging difference (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging type affects handling, storage, and assembly processes only. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Why is the tolerance specification different between these parts?

A: The RS01A1R000FS70 is specified with ±1% tolerance, representing a tighter manufacturing specification compared to the ±5% tolerance of CW0011R000JS70. Both tolerances are within acceptable ranges for wirewound resistor applications; selection depends on circuit accuracy requirements.

Q: Are both parts suitable for moisture-sensitive applications?

A: Yes. Both parts feature moisture-resistant construction and are classified as Moisture Sensitivity Level (MSL): Not Applicable, indicating they are not affected by moisture exposure during storage or handling.

Q: What is the significance of the identical temperature coefficient?

A: Both parts maintain ±50ppm/°C temperature coefficient, ensuring consistent resistance stability across temperature variations. This parameter is critical for precision applications and is identical between the main part and substitute.
