CW02BR2000JS70 Equivalent & Substitute Parts

Part Overview

The CW02BR2000JS70 is a 200 mOhms ±5% 3.75W through-hole axial wirewound resistor manufactured by Vishay Dale. This component is designed for applications requiring low-resistance, high-power dissipation in a compact axial package with moisture-resistant construction. The part is currently active in production with 707 units available in tape and reel packaging. Substitute parts are necessary when tape and reel packaging is unavailable or when alternative compliance certifications are required for specific applications.

Substitute Part Grouping Explanation

Substitution of the CW02BR2000JS70 is determined by electrical and mechanical parameter equivalence within the CW series. The following parameters must remain constant for valid substitution:

• Resistance value: 200 mOhms
• Tolerance: ±5%
• Power rating: 3.75W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.188" Dia x 0.562" L
• Operating temperature range: -65°C ~ 350°C
• Moisture-resistant construction

The primary difference between the main part and its substitute is packaging format (tape and reel versus cut tape) and compliance certifications. Both parts are manufactured by Vishay Dale within the same CW series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CW02BR2000JS70 and CW02BR2000JE70 are electrically and mechanically equivalent and suitable for direct substitution in circuit applications. Selection between these parts should be based on the following criteria:

CW02BR2000JS70 is appropriate when tape and reel packaging is required for automated assembly processes and when RoHS non-compliance is acceptable for the application.

CW02BR2000JE70 is appropriate when cut tape packaging is acceptable, when ROHS3 compliance is required, when REACH unaffected status is necessary, or when higher inventory availability is needed. This part offers superior compliance certifications and greater stock availability.

Both parts share identical electrical performance, physical dimensions, and thermal characteristics. The choice between them depends on packaging requirements and regulatory compliance needs specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can CW02BR2000JE70 be used as a direct replacement for CW02BR2000JS70?

A: Yes. Both parts are electrically and mechanically identical with the same resistance value, tolerance, power rating, physical dimensions, and operating temperature range. The primary differences are packaging format and compliance certifications.

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 with pick-and-place equipment. Cut tape packaging is used for lower-volume applications or manual assembly. Both formats contain the same component; the difference is in delivery and handling method.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics. Selection should be based on regulatory requirements for the end application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.188" diameter by 0.562" length (4.78mm x 14.27mm) and are housed in identical axial packages. They are mechanically interchangeable on circuit boards.

Q: What does REACH Unaffected status mean?

A: REACH Unaffected indicates the part does not contain substances of very high concern (SVHC) listed under the REACH regulation. REACH Affected means the part may contain such substances. Selection depends on regulatory requirements for the target market.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -65°C to 350°C and maintain their electrical specifications throughout this range.
