CW02B100R0JS70 Equivalent & Substitute Parts

Part Overview

The CW02B100R0JS70 is a 100 Ohm, 3.75W wirewound axial resistor manufactured by Vishay Dale. 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 836 units available in tape and 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

The CW02B100R0JE70 qualifies as a parametric equivalent to the CW02B100R0JS70 based on the following criteria:

All electrical parameters are identical: 100 Ohm resistance, ±5% tolerance, 3.75W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range. Physical dimensions remain unchanged at 0.188" diameter by 0.562" length. Both parts use wirewound composition with moisture-resistant features and maintain two terminations.

The primary difference is packaging format: CW02B100R0JS70 is supplied in Tape & Reel (TR) configuration, while CW02B100R0JE70 is supplied in Cut Tape (CT) configuration. This distinction affects handling, storage, and automated assembly processes but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and are manufactured by Vishay Dale within the CW series. Selection between CW02B100R0JS70 and CW02B100R0JE70 depends on packaging requirements and regulatory compliance needs.

The CW02B100R0JS70 in Tape & Reel format is suitable for high-volume automated assembly operations. However, it carries RoHS non-compliant status and REACH Affected designation.

The CW02B100R0JE70 in Cut Tape format accommodates lower-volume applications and manual assembly processes. This variant achieves ROHS3 compliance and REACH Unaffected status, making it preferable for applications subject to environmental and regulatory restrictions.

Both parts are electrically and mechanically interchangeable when packaging format and compliance requirements align with application specifications.

Frequently Asked Questions (FAQ)

Q: Are CW02B100R0JS70 and CW02B100R0JE70 electrically identical?

A: Yes. Both parts deliver identical electrical performance: 100 Ohm resistance at ±5% tolerance, 3.75W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating range.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments, suitable for manual assembly or lower-volume production runs.

Q: Can I substitute CW02B100R0JE70 for CW02B100R0JS70 in my design?

A: Substitution is possible when your assembly process accommodates Cut Tape format and when ROHS3 compliance and REACH Unaffected status meet your regulatory requirements. Verify packaging compatibility with your production equipment before implementation.

Q: What does RoHS3 Compliant mean for the CW02B100R0JE70?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This designation is required for many applications in regulated markets.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both CW02B100R0JS70 and CW02B100R0JE70 operate reliably up to 350°C, making them suitable for high-temperature circuit designs requiring wirewound resistor performance.
