CW02B350R0JS70 Equivalent & Substitute Parts

Part Overview

The CW02B350R0JS70 is a 350 Ohm, 3.75W axial wirewound 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 and available in Tape & Reel packaging. Identifying equivalent substitute parts is necessary when Tape & Reel packaging is unavailable or when compliance requirements differ between procurement specifications.

Substitute Part Grouping Explanation

Substitute parts for the CW02B350R0JS70 are determined by electrical and mechanical parameter equivalence within the Vishay Dale CW series. The substitution criteria are based on the following parameters:

• Electrical Parameters: Resistance value (350 Ohms), tolerance (±5%), power rating (3.75W), and temperature coefficient (±30ppm/°C) must be identical
• Mechanical Parameters: Package type (Axial), physical dimensions (0.188" Dia x 0.562" L), and number of terminations (2) must match
• Material Composition: Wirewound construction with moisture-resistant properties must be maintained
• Operating Specifications: Temperature range (-65°C ~ 350°C) must be equivalent or superior
• Packaging Format: Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) while maintaining identical component specifications

The CW02B350R0JE70 qualifies as a direct substitute based on complete electrical and mechanical parameter alignment, with the primary difference being packaging format.

Engineering Selection Recommendations

CW02B350R0JE70 as Primary Substitute

The CW02B350R0JE70 is a direct functional equivalent to the CW02B350R0JS70. Both parts are manufactured by Vishay Dale within the CW series and share identical electrical specifications, mechanical dimensions, and operating characteristics. The substitute part is suitable for applications requiring the same 350 Ohm, 3.75W axial wirewound resistor configuration.

Compliance Considerations

The CW02B350R0JE70 offers improved regulatory compliance status compared to the main part. The substitute is ROHS3 compliant and REACH unaffected, whereas the CW02B350R0JS70 is RoHS non-compliant and REACH affected. Selection between these parts should account for end-product regulatory requirements and supply chain compliance mandates.

Packaging Format Difference

The primary distinction between the two parts is packaging format. The CW02B350R0JS70 is supplied in Tape & Reel format, while the CW02B350R0JE70 is supplied in Cut Tape format. This difference affects handling, storage, and automated assembly processes but does not impact component performance or electrical characteristics. Selection should be based on manufacturing process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are the CW02B350R0JS70 and CW02B350R0JE70 electrically identical?

A: Yes. Both parts have identical resistance (350 Ohms), tolerance (±5%), power rating (3.75W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). They are functionally equivalent in all electrical parameters.

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

A: Tape & Reel packaging supplies components wound on a continuous reel, suitable for high-volume automated assembly. Cut Tape packaging supplies components in individual tape segments, typically used for lower-volume applications or manual assembly. Both formats contain identical components with no performance difference.

Q: Can I use CW02B350R0JE70 in place of CW02B350R0JS70 in my circuit?

A: Yes. The CW02B350R0JE70 is a direct substitute with identical electrical and mechanical specifications. Circuit performance will be unchanged.

Q: Why does the substitute part have different RoHS and REACH compliance status?

A: Compliance status reflects manufacturing processes and material sourcing at the time of production. The CW02B350R0JE70 represents a newer production variant with improved regulatory compliance. Both parts are functionally equivalent; compliance selection depends on end-product requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical axial package dimensions of 0.188" Dia x 0.562" L (4.78mm x 14.27mm). They are mechanically interchangeable in circuit board layouts and through-hole applications.

Q: Which part should I select for new designs?

A: Selection should be based on specific project requirements. For applications requiring ROHS3 compliance and REACH unaffected status, the CW02B350R0JE70 is the appropriate choice. For applications with no compliance restrictions, either part is suitable based on packaging availability and procurement preferences.
