Substitute Part Grouping Explanation

Substitution eligibility for the CW02B5R000JS70 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 Ohms
• Tolerance: ±5%
• Power rating: 3.75W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 350°C
• Physical dimensions: 0.188" Dia x 0.562" L
• Moisture resistance feature

The primary difference between the main part and its substitute lies in packaging format (tape and reel versus cut tape) and compliance certifications. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CW02B5R000JS70 and CW02B5R000JE70 are functionally equivalent and maintain identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The CW02B5R000JE70 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to environmental regulations and RoHS requirements. This part is available in higher inventory (1780 units) and is supplied in cut tape format.

The CW02B5R000JS70 is available in tape and reel packaging, which may be preferred for automated assembly processes. This part carries RoHS non-compliant and REACH affected designations and should be selected only when regulatory compliance is not a requirement.

Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications.

Frequently Asked Questions (FAQ)

Q: Are CW02B5R000JS70 and CW02B5R000JE70 electrically identical?

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

Q: What is the difference between tape and reel and cut tape packaging?

A: Tape and reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape (CT) packaging provides components on individual tape segments, typically for manual assembly or lower-volume applications. Both formats contain the same component.

Q: Can I use CW02B5R000JE70 as a direct replacement for CW02B5R000JS70?

A: Yes, from an electrical and mechanical standpoint. However, verify that your application requirements align with the compliance certifications. CW02B5R000JE70 is ROHS3 compliant and REACH unaffected, while CW02B5R000JS70 is RoHS non-compliant and REACH affected.

Q: Why would I choose one part over the other if they are electrically identical?

A: Selection depends on packaging requirements (automated assembly versus manual handling), regulatory compliance needs (RoHS3 and REACH status), and inventory availability. CW02B5R000JE70 offers better compliance certifications and higher stock levels.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.188" diameter by 0.562" length (4.78mm x 14.27mm) and are housed in axial package configuration with two terminations.
