CW02B25R00JS70 Equivalent & Substitute Parts

Part Overview

The CW02B25R00JS70 is a 25 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 1021 units in stock. Substitute parts are necessary when tape and reel packaging (TR) is unavailable or when compliance requirements differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW02B25R00JS70 is determined by the following critical parameters:

• Resistance value: 25 Ohms
• Tolerance: ±5%
• Power rating: 3.75W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Physical dimensions: 0.188" Dia x 0.562" L
• Moisture resistance feature

The CW02B25R00JE70 qualifies as a direct substitute because it maintains identical electrical specifications and physical dimensions. The primary difference is packaging format: the original uses tape and reel (TR) while the substitute uses cut tape (CT). Both are supplied by the same manufacturer in the same CW series.

Engineering Selection Recommendations

The CW02B25R00JE70 serves as a direct electrical and mechanical substitute for the CW02B25R00JS70. Both components are manufactured by Vishay Dale and maintain identical electrical performance across all specified parameters.

Selection between these parts should be based on:

• Packaging requirements: Choose tape and reel (TR) format for automated assembly lines; select cut tape (CT) for manual assembly or lower-volume applications.
• Compliance requirements: The CW02B25R00JE70 offers ROHS3 compliance and REACH unaffected status, whereas the original part is RoHS non-compliant and REACH affected. Applications subject to environmental regulations should prioritize the compliant substitute.
• Inventory availability: Both parts maintain active production status with comparable stock levels.

Frequently Asked Questions (FAQ)

Q: Can CW02B25R00JE70 be used as a direct replacement for CW02B25R00JS70?

A: Yes. Both components are electrically and mechanically identical. The only difference is packaging format: tape and reel versus cut tape. Electrical performance, power rating, temperature range, and physical dimensions are identical.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape packaging provides components in individual tape segments, typically used for manual assembly or lower-volume production runs. The component itself is identical in both formats.

Q: Does the substitute part have different compliance certifications?

A: Yes. The CW02B25R00JE70 is ROHS3 compliant and REACH unaffected, while the original CW02B25R00JS70 is RoHS non-compliant and REACH affected. Applications requiring environmental compliance should use the substitute part.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.188" diameter by 0.562" length (4.78mm x 14.27mm). They are mechanically interchangeable on PCBs and in through-hole applications.

Q: What is the temperature coefficient difference, if any?

A: Both parts share an identical temperature coefficient of ±30ppm/°C, ensuring equivalent thermal stability across the operating range of -65°C to 350°C.
