CW02B2R000JS70 Equivalent & Substitute Parts

Part Overview

The CW02B2R000JS70 is a 2 Ohm, 3.75W wirewound axial resistor manufactured by Vishay Dale in the CW series. This through-hole component 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 902 units available in tape and reel packaging. Substitute parts are necessary when tape and reel packaging is unavailable or when RoHS3 compliance is required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

The CW02B2R000JE70 qualifies as a parametric equivalent to the CW02B2R000JS70 based on the following criteria:

• Identical resistance value: 2 Ohms
• Identical tolerance: ±5%
• Identical power rating: 3.75W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical physical dimensions: 0.188" Dia x 0.562" L (4.78mm x 14.27mm)
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -65°C ~ 350°C
• Identical moisture-resistant feature
• Identical number of terminations: 2

The primary difference between these parts is packaging format: the main part uses tape and reel (TR) packaging, while the substitute uses cut tape (CT) packaging. Both are manufactured by Vishay Dale within the CW series and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CW02B2R000JS70 and CW02B2R000JE70 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The CW02B2R000JS70 is suitable for applications where tape and reel packaging is required for automated assembly processes. The CW02B2R000JE70 offers ROHS3 compliance and REACH unaffected status, making it the appropriate choice for applications subject to RoHS3 regulations or REACH compliance requirements. The CW02B2R000JE70 also provides significantly higher inventory availability at 3600 units compared to 902 units for the main part.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. Both parts have identical resistance (2 Ohms), tolerance (±5%), power rating (3.75W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C ~ 350°C). They are fully electrically equivalent.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging? A: Tape and reel packaging is used for high-volume automated assembly, where components are supplied on continuous tape wound on reels. Cut tape packaging provides individual component strips cut from the same tape format, suitable for lower-volume applications or manual assembly. Both formats contain the same component.

Q: Why does the CW02B2R000JE70 have ROHS3 compliance while the main part does not? A: RoHS3 compliance status is determined by the manufacturing process and material composition used by the manufacturer. The CW02B2R000JE70 meets ROHS3 requirements, while the CW02B2R000JS70 does not. For applications requiring RoHS3 certification, the CW02B2R000JE70 is the appropriate selection.

Q: Can I use the CW02B2R000JE70 in place of the CW02B2R000JS70 in automated assembly? A: Cut tape packaging can be used in automated assembly with appropriate tape feeders, though tape and reel is the standard format for high-speed automated lines. Verify your assembly equipment compatibility with cut tape format before substitution.

Q: Are there any mechanical differences between these parts? A: No. Both parts have identical physical dimensions (0.188" Dia x 0.562" L / 4.78mm x 14.27mm), axial package type, and two terminations. They are mechanically interchangeable.
