Substitute Part Grouping Explanation

Substitution eligibility for the CW005100R0JS73 is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 6.5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Physical dimensions: 0.312" Dia x 0.875" L
• Moisture resistance feature

The CW005100R0JE73 meets all electrical and mechanical specifications required for direct substitution. The primary difference between the main part and its substitute is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. Both formats contain identical components with identical electrical characteristics.

Engineering Selection Recommendations

The CW005100R0JE73 is a direct functional equivalent to the CW005100R0JS73 for all electrical and mechanical applications. Selection between these parts should be based on the following criteria:

Packaging Format Compatibility: The main part (CW005100R0JS73) is supplied in Tape & Reel format, suitable for automated pick-and-place assembly systems. The substitute (CW005100R0JE73) is supplied in Cut Tape format, appropriate for manual assembly or lower-volume production runs.

Regulatory Compliance: The substitute part (CW005100R0JE73) carries ROHS3 compliance and REACH unaffected status, providing advantages for applications subject to European Union environmental regulations. The main part is RoHS non-compliant and REACH affected, which may restrict use in certain regulated markets.

Supply Chain Availability: The substitute part maintains significantly higher inventory levels (16250 units versus 666 units), providing improved supply chain security and shorter lead times for procurement.

Both parts are active products from the same manufacturer and series, ensuring long-term availability and consistent quality standards.

Frequently Asked Questions (FAQ)

Q: Can CW005100R0JE73 be used as a direct replacement for CW005100R0JS73 in circuit design?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values, tolerance, power ratings, temperature coefficients, and operating temperature ranges. The only difference is the packaging format (Cut Tape versus Tape & Reel).

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, optimized for automated assembly equipment. Cut Tape (CT) packaging supplies the same components on shorter tape segments, suitable for manual assembly or lower-volume applications. The components themselves are identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical electrical specifications: 100 Ohm resistance, ±5% tolerance, 6.5W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range.

Q: Why does the substitute part have better RoHS and REACH compliance?

A: The CW005100R0JE73 is manufactured to ROHS3 standards and is REACH unaffected, reflecting current environmental compliance requirements. The main part predates these standards. Both parts are from the same manufacturer and series, but the substitute represents a more recent production variant with updated compliance certifications.

Q: Which part should I select for automated assembly?

A: The CW005100R0JS73 in Tape & Reel format is optimized for automated pick-and-place systems. If this part is unavailable, the CW005100R0JE73 in Cut Tape format requires manual handling or alternative assembly processes.

Q: Is there a performance penalty for using the Cut Tape version?

A: No. The Cut Tape format does not affect electrical or thermal performance. The difference is purely in packaging and handling methodology during assembly.
