Substitute Part Grouping Explanation

Substitution eligibility for the CW00522R00JS73 is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 Ohms
• Tolerance: ±5%
• Power rating: 6.5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Moisture-resistant feature requirement
• Physical dimensions: 0.312" Dia x 0.875" L

The CW00522R00JE73 meets all electrical and mechanical specifications required for direct substitution. The primary difference 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 are manufactured by Vishay Dale within the same CW series and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CW00522R00JS73 and CW00522R00JE73 are functionally equivalent and maintain active production status. Selection between these parts should be based on the following factors:

The CW00522R00JE73 offers improved regulatory compliance, meeting ROHS3 requirements and REACH unaffected status, compared to the non-compliant and REACH-affected status of the main part. This substitute is preferable for applications subject to environmental regulations or customer compliance mandates.

Packaging format selection depends on assembly process requirements. The Tape & Reel format of the CW00522R00JS73 is optimized for high-volume automated pick-and-place assembly. The Cut Tape format of the CW00522R00JE73 is suitable for lower-volume manual assembly or mixed-component kitting operations.

The CW00522R00JE73 maintains significantly higher inventory availability at 3133 units compared to 736 units for the main part, providing supply chain advantages for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can CW00522R00JE73 be used as a direct replacement for CW00522R00JS73?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values, power ratings, temperature coefficients, and operating ranges. The only differences are packaging format and regulatory compliance status.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated assembly equipment. Cut Tape packaging supplies the same carrier tape in shorter segments, suitable for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Are there dimensional differences between these parts?

A: Dimensions are essentially identical. The CW00522R00JS73 measures 0.312" Dia x 0.875" L (7.92mm x 22.22mm), while the CW00522R00JE73 measures 0.312" Dia x 0.875" L (7.92mm x 22.23mm). The 0.01mm difference in length is within manufacturing tolerance and does not affect functional compatibility.

Q: Which part should be selected for RoHS-compliant applications?

A: The CW00522R00JE73 is ROHS3 compliant and REACH unaffected, making it the appropriate choice for applications requiring environmental regulation compliance. The CW00522R00JS73 is RoHS non-compliant and REACH affected.

Q: Does packaging format affect electrical performance?

A: No. Packaging format is a supply and assembly consideration only. Both Tape & Reel and Cut Tape formats deliver identical electrical characteristics and performance.
