Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW0101K000JS73 is determined by the following critical parameters:

• Resistance value: 1 kOhms
• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Physical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm)
• Features: Moisture Resistant
• Terminations: 2

The substitute part CW0101K000JE73 matches all electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both parts are manufactured by Vishay Dale within the same CW series.

Parameter Comparison

Engineering Selection Recommendations

Both CW0101K000JS73 and CW0101K000JE73 are functionally equivalent for circuit applications requiring a 1 kOhms ±5% 13W wirewound axial resistor. Selection between these parts should be based on:

Packaging format requirements: The CW0101K000JS73 is supplied in Tape & Reel format suitable for automated assembly processes. The CW0101K000JE73 is supplied in Cut Tape format suitable for manual or semi-automated handling.

Compliance requirements: The CW0101K000JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental regulations. The CW0101K000JS73 is RoHS non-compliant and REACH affected.

Both parts share identical electrical characteristics, physical dimensions, and thermal performance specifications.

Frequently Asked Questions (FAQ)

Q: Can CW0101K000JE73 be used as a direct replacement for CW0101K000JS73?

A: Yes. Both parts have identical electrical specifications (1 kOhms ±5%, 13W), composition (wirewound), temperature performance (-65°C to 350°C), and physical dimensions (0.375" Dia x 1.781" L). The difference is packaging format: Tape & Reel versus Cut Tape. Functional performance in the circuit is identical.

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

A: Tape & Reel packaging supplies components on continuous tape wound on a reel, optimized for high-speed automated assembly equipment. Cut Tape packaging supplies components on tape segments, suitable for manual placement or lower-volume assembly processes. Both formats contain the same component.

Q: Are there compliance differences between these parts?

A: Yes. The CW0101K000JE73 is ROHS3 compliant and REACH unaffected. The CW0101K000JS73 is RoHS non-compliant and REACH affected. Applications subject to environmental regulations should specify the CW0101K000JE73.

Q: Do these parts have the same temperature performance?

A: Yes. Both parts operate from -65°C to 350°C with a temperature coefficient of ±30ppm/°C.

Q: Can packaging format affect circuit performance?

A: No. Packaging format affects only handling, assembly method, and supply logistics. Electrical and thermal performance is identical between Tape & Reel and Cut Tape formats of the same component.
