Substitute Part Grouping Explanation

Substitute parts for the CW00515K00JS73 are determined by strict equivalence across the following critical parameters: resistance value (15 kOhms), tolerance (±5%), power rating (6.5W), composition (wirewound), package type (axial), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), physical dimensions (0.312" Dia x 0.875" L), and moisture-resistant features. The primary difference between the main part and its substitute is the packaging format: tape and reel (TR) versus cut tape (CT). Both formats contain identical components with the same electrical and mechanical specifications, differing only in how units are supplied and handled during assembly operations.

Parameter Comparison

Engineering Selection Recommendations

Both the CW00515K00JS73 and CW00515K00JE73 are functionally equivalent and interchangeable from an electrical and mechanical standpoint. Selection between these parts should be based on packaging requirements and compliance status. The CW00515K00JS73 is supplied in tape and reel format and is RoHS non-compliant with REACH Affected status. The CW00515K00JE73 is supplied in cut tape format and is ROHS3 compliant with REACH Unaffected status. For applications requiring RoHS3 compliance or REACH unaffected status, the CW00515K00JE73 is the appropriate selection. For applications where packaging format is the determining factor, either part may be selected based on assembly line compatibility and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are CW00515K00JS73 and CW00515K00JE73 electrically identical? A: Yes. Both parts have identical resistance (15 kOhms), tolerance (±5%), power rating (6.5W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C). They are functionally equivalent for all electrical 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 supplies components on individual tape segments. Both formats contain identical components; the difference is in supply format and handling during assembly.

Q: Can I use CW00515K00JE73 as a direct replacement for CW00515K00JS73? A: Yes, provided your assembly process is compatible with cut tape packaging. The electrical and mechanical specifications are identical. Verify that your assembly equipment can accommodate the cut tape format before substitution.

Q: What compliance differences exist between these parts? A: CW00515K00JS73 is RoHS non-compliant and REACH Affected. CW00515K00JE73 is ROHS3 compliant and REACH Unaffected. Select based on your application's regulatory requirements.

Q: Are the physical dimensions identical? A: Yes. Both parts have identical dimensions of 0.312" diameter by 0.875" length (7.92mm x 22.22mm), ensuring mechanical compatibility in all circuit board layouts and enclosures.

Q: Which part should I select for new designs? A: For new designs, CW00515K00JE73 is recommended due to ROHS3 compliance and REACH unaffected status, which align with current regulatory standards. Verify packaging format compatibility with your assembly process.
