Substitute Part Grouping Explanation

The CW00520K00JE73 qualifies as a parametric equivalent to the CW00520K00JS73 based on strict electrical and mechanical compatibility. Both parts share identical specifications across all critical parameters: 20 kOhms resistance, ±5% tolerance, 6.5W power rating, wirewound composition, axial package configuration, and 0.312" Dia x 0.875" L physical dimensions. The primary distinction between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. Both parts maintain the same series designation (CW), product status (Active), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). The substitution is valid for applications where Cut Tape packaging is acceptable as an alternative to Tape & Reel delivery.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW00520K00JS73 and CW00520K00JE73 depends on packaging requirements and regulatory compliance needs. The CW00520K00JS73 in Tape & Reel format is suitable for high-volume automated assembly processes. The CW00520K00JE73 in Cut Tape format provides equivalent electrical and mechanical performance with improved regulatory compliance: it meets ROHS3 requirements and is REACH Unaffected, compared to the main part which is RoHS non-compliant and REACH Affected. Both parts are Active products with full inventory availability. Component selection should align with production methodology, supply chain requirements, and applicable regulatory frameworks for the end application.

Frequently Asked Questions (FAQ)

Q: Are CW00520K00JS73 and CW00520K00JE73 electrically identical?

A: Yes. Both parts have identical electrical specifications: 20 kOhms resistance, ±5% tolerance, 6.5W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating range.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume processes.

Q: Can I substitute CW00520K00JE73 for CW00520K00JS73 in my assembly process?

A: Substitution is valid if your assembly process can accommodate Cut Tape packaging instead of Tape & Reel format. Electrical and mechanical compatibility is confirmed across all specifications.

Q: What are the compliance differences between these parts?

A: CW00520K00JE73 is ROHS3 Compliant and REACH Unaffected. CW00520K00JS73 is RoHS non-compliant and REACH Affected. Select based on your regulatory requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial dimensions of 0.312" Dia x 0.875" L (7.92mm x 22.22mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Which part has better availability?

A: CW00520K00JE73 has 1559 units in stock compared to 1001 units for CW00520K00JS73, providing higher immediate availability.
