Substitute Part Grouping Explanation

The CW0101R000JE73 qualifies as a parametric equivalent to the CW0101R000JS73 based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Resistance value: 1 Ohms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 13W (exact match)
• Composition: Wirewound (exact match)
• Package case: Axial (exact match)
• Temperature coefficient: ±50ppm/°C (exact match)
• Operating temperature range: -65°C to 350°C (exact match)
• Physical dimensions: 0.375" Dia x 1.781" L (exact match)
• Moisture resistance: Present (exact match)

The only difference between these parts is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both packaging formats are standard industry options for through-hole axial resistors and do not affect electrical performance or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CW0101R000JS73 and CW0101R000JE73 are active production parts from Vishay Dale with identical electrical and mechanical performance. Selection between these parts should be based on the following factors:

The CW0101R000JE73 offers compliance advantages, meeting ROHS3 requirements and REACH unaffected status, making it suitable for applications with regulatory compliance requirements. This part also has higher inventory availability at 2324 units compared to 977 units for the main part.

The CW0101R000JS73 is available in Tape & Reel packaging, which is preferred for automated assembly processes requiring continuous reel feeding. The CW0101R000JE73 in Cut Tape format is suitable for manual assembly, kit builds, or lower-volume production runs.

Both parts are suitable for high-temperature applications up to 350°C and maintain stable performance across the full operating range with identical temperature coefficients.

Frequently Asked Questions (FAQ)

Q: Can CW0101R000JE73 be used as a direct replacement for CW0101R000JS73?

A: Yes. Both parts have identical electrical specifications (1 Ohm, ±5%, 13W), identical physical dimensions (0.375" Dia x 1.781" L), and identical thermal characteristics (-65°C to 350°C operating range, ±50ppm/°C temperature coefficient). The only difference is packaging format.

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 equipment. Cut Tape (CT) packaging provides individual segments cut from the tape, suitable for manual assembly, prototyping, or lower-volume applications. Both formats contain the same component with identical performance.

Q: Are there any compatibility issues when switching between these parts?

A: No compatibility issues exist. Both parts are axial through-hole resistors with identical lead spacing, diameter, and length. They mount identically on PCBs and function identically in circuits.

Q: Which part should I select for high-temperature applications?

A: Both parts are rated for -65°C to 350°C operation with identical temperature coefficients. Selection should be based on packaging requirements and compliance needs rather than thermal performance.

Q: What are the compliance differences between these parts?

A: The CW0101R000JE73 is ROHS3 compliant and REACH unaffected, while the CW0101R000JS73 is RoHS non-compliant and REACH affected. For applications requiring regulatory compliance, the CW0101R000JE73 is the appropriate selection.
