Key Parameters

Substitute Part Grouping Explanation

Substitution of the CW01020K00JS70 is determined by electrical and mechanical parameter equivalence within the CW series wirewound resistor family. The following parameters must remain constant for valid substitution:

• Resistance value: 20 kOhms
• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.375" Dia x 1.781" L
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Moisture resistance feature

The primary difference between the main part and its substitute is the packaging format: Tape & Reel versus Cut Tape. This distinction affects inventory management and automated assembly processes but does not alter electrical or mechanical performance.

Engineering Selection Recommendations

Both CW01020K00JS70 and CW01020K00JE73 are electrically and mechanically equivalent and interchangeable in circuit applications. Selection between these parts should be based on the following criteria:

CW01020K00JS70 (Tape & Reel): Select this part when automated pick-and-place assembly is required or when bulk component handling through tape dispensing systems is preferred.

CW01020K00JE73 (Cut Tape): Select this part when RoHS3 compliance is mandated by design specifications or when REACH-unaffected status is required for regulatory compliance. Cut Tape packaging is suitable for manual assembly or lower-volume production runs.

Both parts maintain identical electrical performance and thermal characteristics across the full operating temperature range. The choice between them is determined by packaging requirements and regulatory compliance needs, not by functional performance.

Frequently Asked Questions (FAQ)

Q: Can CW01020K00JE73 be used as a direct replacement for CW01020K00JS70 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only differences are packaging format and compliance certifications. No circuit modifications are required.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated assembly equipment. Cut Tape packaging provides individual components or small quantities cut from tape, suitable for manual assembly or prototyping. Both formats contain the same component.

Q: Does the RoHS3 compliance difference affect circuit performance?

A: No. RoHS3 compliance refers to material composition restrictions and does not alter electrical or thermal performance. The CW01020K00JE73 meets RoHS3 standards while the CW01020K00JS70 does not. Selection depends on regulatory requirements for your application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm). They are mechanically interchangeable in PCB layouts and mechanical assemblies.

Q: What does REACH Unaffected status mean?

A: REACH Unaffected indicates the component does not contain substances of very high concern (SVHC) listed under EU REACH regulations. REACH Affected means the component may contain listed substances. Selection depends on your regulatory jurisdiction and supply chain requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -65°C to 350°C with the same ±30ppm/°C temperature coefficient. They are fully interchangeable for thermal performance.
