CW0014R000JS70 Equivalent & Substitute Parts

Part Overview

The CW0014R000JS70 is a 4 Ohms ±5% through-hole resistor with axial package configuration, manufactured by Vishay Dale as part of the CW series. This wirewound resistor features moisture-resistant construction and operates across a wide temperature range from -65°C to 350°C. The part is currently active in production with 1036 units available in stock. Substitute parts are identified when equivalent electrical performance is required but the original part is unavailable, or when enhanced specifications such as improved tolerance or power rating are necessary for circuit requirements.

Substitute Part Grouping Explanation

The RS01A4R000FS70 qualifies as a direct substitute for the CW0014R000JS70 based on the following critical parameters:

• Identical resistance value: 4 Ohms
• Identical package configuration: Axial
• Identical physical dimensions: 0.094" Dia x 0.406" L (2.39mm x 10.31mm)
• Identical composition: Wirewound
• Identical features: Moisture Resistant
• Identical temperature coefficient: ±50ppm/°C
• Identical number of terminations: 2

The RS01A4R000FS70 provides enhanced specifications in tolerance (±1% versus ±5%) and rated power (1W versus unspecified), making it suitable for applications requiring tighter tolerance control. The operating temperature range of the substitute extends to 250°C maximum, which is lower than the original part's 350°C maximum but remains adequate for most industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CW0014R000JS70 and RS01A4R000FS70 are active production parts from Vishay Dale with identical RoHS and export classification status. Selection between these parts depends on application-specific requirements:

The CW0014R000JS70 is appropriate for applications requiring the extended operating temperature range up to 350°C and standard ±5% tolerance specifications. This part is supplied in Tape & Reel packaging, suitable for high-volume automated assembly processes.

The RS01A4R000FS70 is appropriate for applications requiring tighter tolerance control (±1%) and explicit power rating specification (1W). This part is supplied in Cut Tape packaging, suitable for lower-volume or mixed-component assembly operations. The maximum operating temperature of 250°C is sufficient for standard industrial and commercial applications.

Both parts share identical electrical characteristics in resistance value, temperature coefficient, and moisture-resistant wirewound construction, ensuring functional equivalence in circuits where tolerance and temperature range are not limiting factors.

Frequently Asked Questions (FAQ)

Q: Can RS01A4R000FS70 be used as a direct replacement for CW0014R000JS70?

A: Yes. Both parts have identical resistance (4 Ohms), package configuration (Axial), physical dimensions (0.094" Dia x 0.406" L), and composition (Wirewound). The RS01A4R000FS70 provides improved tolerance (±1% versus ±5%) and explicit power rating (1W). Verify that the operating temperature requirement does not exceed 250°C, as this is the maximum for the substitute part.

Q: What is the difference in packaging between these parts?

A: The CW0014R000JS70 is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly at high volumes. The RS01A4R000FS70 is supplied in Cut Tape (CT) format, suitable for manual handling or lower-volume assembly operations. Both formats contain identical components.

Q: Are there compliance differences between these parts?

A: Both parts share identical RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS code (8533.21.0080). The RS01A4R000FS70 carries additional REACH Affected designation. Verify compliance requirements for your specific application and region.

Q: What is the significance of the tolerance difference?

A: The CW0014R000JS70 has ±5% tolerance, while the RS01A4R000FS70 has ±1% tolerance. Tighter tolerance (±1%) provides more precise resistance values and is required in applications where circuit performance depends on accurate component values. Standard tolerance (±5%) is acceptable for general-purpose applications where resistance variation within this range does not affect circuit function.

Q: Can CW0014R000JS70 be used in applications requiring operation above 250°C?

A: Yes. The CW0014R000JS70 operates up to 350°C maximum, compared to 250°C for the RS01A4R000FS70. If your application requires sustained operation above 250°C, the CW0014R000JS70 is the appropriate selection.
