Substitute Part Grouping Explanation

The CW02C2R000JS70 and its identified substitute share identical electrical and mechanical specifications across all critical parameters: resistance value, tolerance, power rating, temperature coefficient, operating temperature range, composition, and physical dimensions. The substitution is valid based on these matching parameters. The primary difference between the main part and substitute lies in packaging format and RoHS compliance status. The CW02C2R000JS70 is supplied in Tape & Reel (TR) format with RoHS non-compliant status, while the substitute CW02C2R000JE70 is supplied in Cut Tape (CT) format with ROHS3 compliance. Both parts maintain the same axial package configuration and are suitable for through-hole assembly applications where these packaging and compliance differences are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW02C2R000JS70 and CW02C2R000JE70 is determined by packaging requirements and regulatory compliance needs. The CW02C2R000JS70 in Tape & Reel format is suitable for high-volume automated assembly operations. The CW02C2R000JE70 in Cut Tape format with ROHS3 compliance is appropriate for applications requiring RoHS3 certification or for lower-volume manual assembly processes. Both parts are active products with equivalent electrical performance and identical thermal characteristics. Selection should be based on assembly process compatibility and applicable regulatory requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Are CW02C2R000JS70 and CW02C2R000JE70 electrically identical? A: Yes. Both parts have identical resistance (2 Ohms), tolerance (±5%), power rating (3.25W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 350°C).

Q: What is the primary difference between these two parts? A: The main differences are packaging format and RoHS compliance. CW02C2R000JS70 uses Tape & Reel packaging and is RoHS non-compliant, while CW02C2R000JE70 uses Cut Tape packaging and is ROHS3 compliant.

Q: Can I use CW02C2R000JE70 as a direct replacement for CW02C2R000JS70 in my assembly process? A: Direct replacement depends on your assembly equipment and process. If your equipment handles Cut Tape format and ROHS3 compliance is acceptable or required, substitution is valid. If your process requires Tape & Reel format, the substitute is not suitable without process modification.

Q: Do both parts have the same physical dimensions? A: Yes. Both parts have identical axial package dimensions of 0.218" Dia x 0.500" L (5.54mm x 12.70mm) and are suitable for the same PCB footprints.

Q: Which part should I select for RoHS-compliant applications? A: CW02C2R000JE70 is ROHS3 compliant and is the appropriate selection for applications requiring RoHS certification.
