Substitute Part Grouping Explanation

Substitute parts for the CW00518K00JS73 are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to qualify as a direct substitute:

• Resistance value: 18 kOhms
• Tolerance: ±5%
• Power rating: 6.5W
• Composition: Wirewound
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C ~ 350°C
• Package type: Axial
• Physical dimensions: 0.312" Dia x 0.875" L (7.92mm x 22.22mm)
• Moisture resistance feature
• Number of terminations: 2

Packaging format (tape and reel versus cut tape) does not affect electrical or mechanical compatibility and represents the only allowable variation between equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

The CW00518K00JE73 is a direct electrical and mechanical equivalent to the CW00518K00JS73. Both parts are manufactured by Vishay Dale within the CW series and maintain identical specifications across all critical parameters including resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

The primary distinction between these parts is packaging format and regulatory compliance status. The CW00518K00JE73 is supplied in cut tape format and carries ROHS3 compliance with REACH unaffected status, whereas the CW00518K00JS73 is supplied in tape and reel format with RoHS non-compliant and REACH affected designations. Selection between these parts should be based on packaging requirements for your assembly process and applicable regulatory compliance mandates for your end application.

Frequently Asked Questions (FAQ)

Q: Can CW00518K00JE73 be used as a direct replacement for CW00518K00JS73 in circuit applications?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Direct substitution is valid from a functional standpoint.

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

A: Tape and reel (TR) packaging supplies components wound on a continuous reel for automated pick-and-place assembly equipment. Cut tape (CT) packaging supplies components on tape segments cut to specific lengths. Both formats contain identical components; the difference is in handling and assembly process compatibility.

Q: Does the RoHS compliance difference affect component performance?

A: No. RoHS compliance status reflects manufacturing process and material composition restrictions but does not alter the electrical or thermal performance of the component. Selection should be based on regulatory requirements applicable to your end product.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.312" diameter by 0.875" length (7.92mm x 22.22mm). They are mechanically interchangeable in circuit board layouts and mounting applications.

Q: What does REACH unaffected status mean?

A: REACH unaffected status indicates the component does not contain substances of very high concern (SVHC) listed under the REACH regulation. REACH affected status indicates the component may contain listed substances. Selection depends on your regulatory jurisdiction and end-use requirements.
