Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW0051R000JS73 is determined by matching the following critical parameters:

• Resistance value: 1 Ohms
• Tolerance: ±5%
• Power rating: 6.5W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 350°C
• Moisture resistance feature
• Physical dimensions: 0.312" Dia x 0.875" L

The primary substitute CW0051R000JE73 matches all electrical and mechanical parameters. The difference between the main part and this 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 are manufactured by Vishay Dale within the same CW series and maintain identical performance characteristics.

Engineering Selection Recommendations

The CW0051R000JE73 serves as a direct electrical and mechanical equivalent to the CW0051R000JS73. Selection between these parts should be based on the following factors:

Packaging Format: The main part is supplied in Tape & Reel format, suitable for automated assembly processes. The substitute is available in Cut Tape format, appropriate for manual assembly or lower-volume applications.

Compliance Status: The substitute part (CW0051R000JE73) achieves ROHS3 compliance and REACH unaffected status, whereas the main part is RoHS non-compliant and REACH affected. Applications subject to regulatory compliance requirements should specify the substitute part.

Inventory Availability: The substitute part maintains higher stock levels (1001 units versus 816 units), providing improved availability for procurement planning.

Both parts are active products from the same manufacturer and series, ensuring consistent quality and performance characteristics across applications.

Frequently Asked Questions (FAQ)

Q: Can CW0051R000JE73 be used as a direct replacement for CW0051R000JS73?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The difference is packaging format (Cut Tape versus Tape & Reel) and compliance certifications.

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

A: Tape & Reel packaging is used for high-volume automated assembly, where components are fed directly into pick-and-place machines. Cut Tape packaging provides individual component strips suitable for manual assembly or lower-volume production runs.

Q: Does the substitute part meet RoHS requirements?

A: The CW0051R000JE73 is ROHS3 compliant, whereas the main part CW0051R000JS73 is RoHS non-compliant. Applications requiring RoHS compliance should use the substitute part.

Q: Are the physical dimensions identical between the two parts?

A: The dimensions are functionally equivalent. Both parts measure 0.312" Dia x 0.875" L, with a negligible difference of 0.01mm in length (22.22mm versus 22.23mm), which does not affect mechanical fit or performance.

Q: What is the REACH compliance difference?

A: The substitute part (CW0051R000JE73) is REACH unaffected, while the main part is REACH affected. Applications subject to REACH regulations should specify the substitute part.
