CW02BR1000JS70 Equivalent & Substitute Parts

Part Overview

The CW02BR1000JS70 is a 100 mOhms ±5% 3.75W through-hole resistor manufactured by Vishay Dale in the CW series. This axial wirewound resistor features moisture-resistant construction and operates across a temperature range of -65°C to 350°C. The part is currently active in production with 702 units available in Tape & Reel packaging. Substitute parts are identified when packaging format changes or when compliance requirements differ while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CW02BR1000JS70 is determined by the following criteria:

• Resistance value: 100 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3.75W (exact match required)
• Composition: Wirewound (exact match required)
• Package case: Axial (exact match required)
• Physical dimensions: 0.188" Dia x 0.562" L (exact match required)
• Operating temperature range: -65°C to 350°C (exact match required)
• Moisture resistance feature: Required

The CW02BR1000JE70 qualifies as a direct substitute based on identical electrical specifications and mechanical dimensions. The primary difference is packaging format: the main part uses Tape & Reel (TR) while the substitute uses Cut Tape (CT). Both formats contain the same component with no functional or performance differences.

Parameter Comparison

Engineering Selection Recommendations

Both the CW02BR1000JS70 and CW02BR1000JE70 are functionally equivalent for circuit applications requiring a 100 mOhms ±5% 3.75W axial wirewound resistor. Selection between these parts depends on packaging requirements and regulatory compliance:

The CW02BR1000JS70 in Tape & Reel format is suitable for automated assembly processes. However, it carries RoHS non-compliant status and REACH Affected designation.

The CW02BR1000JE70 in Cut Tape format is suitable for manual assembly or lower-volume production runs. This part meets ROHS3 compliance and carries REACH Unaffected status, making it preferable for applications subject to environmental regulations. Higher inventory availability (1298 units) also supports supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CW02BR1000JE70 replace CW02BR1000JS70 in my circuit?

A: Yes. Both parts have identical electrical specifications (100 mOhms ±5%, 3.75W), composition (wirewound), operating temperature range (-65°C to 350°C), and physical dimensions (0.188" Dia x 0.562" L). The only difference is packaging format: Tape & Reel versus Cut Tape. Electrical performance and mechanical fit are equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies the same components cut from tape and stacked, suitable for manual assembly or lower-volume production. Both formats contain identical components.

Q: Does the substitute part meet RoHS requirements?

A: The CW02BR1000JE70 is ROHS3 compliant, while the main part CW02BR1000JS70 is RoHS non-compliant. If your application requires RoHS compliance, the substitute part is the appropriate selection.

Q: Are there any performance differences between these parts?

A: No. Both parts are manufactured by Vishay Dale in the CW series with identical resistance value, tolerance, power rating, composition, temperature coefficient behavior, and moisture-resistant features. Performance in circuit operation is equivalent.

Q: Which part should I select for new designs?

A: Selection depends on assembly method and regulatory requirements. For automated assembly without RoHS requirements, use CW02BR1000JS70. For manual assembly, lower-volume production, or applications requiring RoHS compliance, use CW02BR1000JE70.
