Key Parameters

Substitute Part Grouping Explanation

Substitution of the CW02B7R500JS70 is determined by equivalence in the following critical parameters: resistance value (7.5 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), and moisture-resistant features. The primary differentiator between the main part and its substitute is the packaging format: Tape & Reel (TR) versus Cut Tape (CT). Both formats deliver identical electrical performance and mechanical compatibility in through-hole applications. Substitution is valid when the end application can accommodate either packaging method during assembly.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW02B7R500JS70 and CW02B7R500JE70 depends on regulatory compliance requirements and assembly process specifications. The CW02B7R500JS70 in Tape & Reel format is suitable for high-volume automated assembly operations and is appropriate for applications where RoHS non-compliance is acceptable. The CW02B7R500JE70 in Cut Tape format is ROHS3 compliant and REACH unaffected, making it the appropriate choice for applications subject to European Union environmental directives or customer specifications requiring RoHS3 compliance. Both parts are electrically and mechanically identical, ensuring functional interchangeability in circuit design. Selection should be based on assembly capability, regulatory jurisdiction, and compliance documentation requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Are CW02B7R500JS70 and CW02B7R500JE70 electrically identical? A: Yes. Both parts have identical resistance (7.5 Ohms), tolerance (±5%), power rating (3.75W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 350°C). They are functionally equivalent in all circuit applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is used for high-volume automated assembly with pick-and-place equipment. Cut Tape (CT) packaging provides individual component strips suitable for lower-volume or manual assembly processes. Both formats contain identical components with the same electrical specifications.

Q: Can I substitute CW02B7R500JE70 for CW02B7R500JS70 in my design? A: Substitution is valid if your assembly process can accommodate Cut Tape packaging and if ROHS3 compliance is acceptable or required for your application. The electrical and mechanical performance are identical.

Q: Why does CW02B7R500JE70 have different RoHS and REACH status? A: RoHS and REACH compliance status reflects regulatory certifications applicable to the specific part number and packaging configuration. CW02B7R500JE70 is ROHS3 compliant and REACH unaffected, making it suitable for applications requiring European Union environmental compliance.

Q: Are the physical dimensions identical between both parts? A: Yes. Both parts have identical axial package dimensions of 0.188" Dia x 0.562" L (4.78mm x 14.27mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should I select for a new design? A: Selection depends on your assembly capability and regulatory requirements. For automated high-volume production, CW02B7R500JS70 (Tape & Reel) is standard. For applications requiring RoHS3 compliance or manual assembly, CW02B7R500JE70 (Cut Tape) is appropriate.
