Substitute Part Grouping Explanation

Substitution eligibility for the CW00525R00JS73 is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 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 construction

The primary difference between the main part and its substitute lies in packaging format: the CW00525R00JS73 is supplied in Tape & Reel (TR) configuration, while the substitute CW00525R00JE73 is supplied in Cut Tape (CT) format. Both parts maintain identical electrical and mechanical specifications, with dimensional variance limited to 0.01mm in length.

Parameter Comparison

Engineering Selection Recommendations

Both CW00525R00JS73 and CW00525R00JE73 are functionally equivalent and maintain identical electrical performance characteristics. Selection between these parts should be based on the following factors:

CW00525R00JS73 (Tape & Reel): Suitable for high-volume automated assembly operations where reel-based component feeding is standard. Appropriate for production environments with established tape & reel handling infrastructure.

CW00525R00JE73 (Cut Tape): Suitable for lower-volume production runs, manual assembly processes, or applications where cut tape packaging reduces waste. This variant offers ROHS3 compliance and REACH unaffected status, making it preferable for applications subject to stricter environmental and regulatory requirements.

Both parts are active products with adequate inventory levels. The choice between them should align with assembly methodology, regulatory compliance requirements, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can CW00525R00JE73 be used as a direct replacement for CW00525R00JS73?

A: Yes. Both parts are electrically and mechanically identical, with the only difference being packaging format (Tape & Reel versus Cut Tape). They are interchangeable in circuit applications.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies individual components or small quantities cut from tape, suitable for manual assembly or lower-volume applications.

Q: Are there compliance differences between these parts?

A: Yes. CW00525R00JE73 is ROHS3 compliant and REACH unaffected, while CW00525R00JS73 is RoHS non-compliant and REACH affected. Applications subject to environmental regulations should specify CW00525R00JE73.

Q: Is there a dimensional difference between these parts?

A: Dimensional variance is negligible. Length differs by 0.01mm (22.22mm versus 22.23mm), which is within manufacturing tolerance and does not affect circuit board layout or mechanical fit.

Q: Which part should be selected for new designs?

A: Selection depends on assembly volume and regulatory requirements. For high-volume automated assembly, CW00525R00JS73 is appropriate. For applications requiring environmental compliance or lower-volume production, CW00525R00JE73 is the preferred choice.
