Key Parameters

Substitute Part Grouping Explanation

Substitution of CW02B1R000JS70 is determined by the following critical parameters that must remain constant:

• Resistance Value: 1 Ohms
• Tolerance: ±5%
• Power Rating: 3.75W
• Composition: Wirewound
• Package Type: Axial
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -65°C to 350°C
• Physical Dimensions: 0.188" Dia x 0.562" L (4.78mm x 14.27mm)
• Features: Moisture Resistant

The primary variable in substitution is packaging format. CW02B1R000JS70 is supplied in Tape & Reel (TR) format, while CW02B1R000JE70 is supplied in Cut Tape (CT) format. Both parts are electrically and mechanically identical, with differences limited to supply packaging and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

CW02B1R000JE70 serves as a direct electrical and mechanical substitute for CW02B1R000JS70. Selection between these parts is determined by supply chain requirements and regulatory compliance needs:

CW02B1R000JS70 is appropriate for applications where Tape & Reel packaging is required for automated assembly processes and where RoHS non-compliance is acceptable within the design framework.

CW02B1R000JE70 is appropriate for applications requiring ROHS3 compliance and REACH unaffected status. This part is supplied in Cut Tape format, suitable for manual assembly or lower-volume production environments.

Both parts maintain identical electrical performance, temperature stability, and moisture resistance characteristics. Selection should be based on packaging format availability, compliance certification requirements, and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Are CW02B1R000JS70 and CW02B1R000JE70 electrically interchangeable?

A: Yes. Both parts have identical resistance value (1 Ohm), tolerance (±5%), power rating (3.75W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 350°C). They are electrically and mechanically interchangeable in circuit applications.

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, suitable for high-speed automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume production runs.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format affects only supply chain logistics and assembly methodology. Electrical and thermal performance remain identical regardless of packaging format.

Q: What is the significance of RoHS and REACH compliance differences?

A: CW02B1R000JS70 is RoHS non-compliant and REACH Affected. CW02B1R000JE70 is ROHS3 Compliant and REACH Unaffected. Selection depends on regulatory requirements applicable to the end application and target markets.

Q: Can CW02B1R000JE70 be used as a direct replacement in existing designs specified for CW02B1R000JS70?

A: Yes, provided that packaging format change from Tape & Reel to Cut Tape is compatible with assembly processes, and compliance certifications meet application requirements.
