Substitute Part Grouping Explanation

The CW0057K500JE73 qualifies as a direct electrical and mechanical substitute for the CW0057K500JS73. Substitution is valid based on the following criteria:

• Identical resistance value: 7.5 kOhms
• Identical tolerance: ±5%
• Identical power rating: 6.5W
• Identical composition: Wirewound
• Identical package case: Axial
• Identical physical dimensions: 0.312" Dia x 0.875" L (7.92mm x 22.22mm)
• Identical temperature coefficient: ±30ppm/°C
• Identical operating temperature range: -65°C ~ 350°C
• Identical moisture resistance feature

The only difference between these parts is the packaging format: CW0057K500JS73 is supplied in Tape & Reel (TR) format, while CW0057K500JE73 is supplied in Cut Tape (CT) format. Both formats contain identical components and are suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CW0057K500JS73 and CW0057K500JE73 are Active status components suitable for equivalent circuit applications. Selection between these parts should be based on packaging requirements and regulatory compliance needs:

The CW0057K500JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental and regulatory requirements. The CW0057K500JS73 maintains RoHS non-compliant status but is available in Tape & Reel packaging format for high-volume automated assembly operations.

Both parts share identical electrical performance characteristics and physical dimensions, ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can CW0057K500JE73 replace CW0057K500JS73 in my circuit design?

A: Yes. Both parts have identical electrical specifications (7.5 kOhms ±5%, 6.5W), composition (wirewound), operating temperature range (-65°C ~ 350°C), and physical dimensions (0.312" Dia x 0.875" L). The difference is packaging format only: Tape & Reel versus Cut Tape.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume or manual assembly operations. The resistor components themselves are identical.

Q: Are there compliance differences between these parts?

A: Yes. CW0057K500JE73 is ROHS3 compliant and REACH unaffected. CW0057K500JS73 is RoHS non-compliant and REACH affected. Select based on your application's regulatory requirements.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±30ppm/°C and operate across the identical temperature range of -65°C ~ 350°C.

Q: Can I use these parts interchangeably in PCB assembly?

A: Electrical and mechanical interchangeability is confirmed. Verify your assembly process compatibility with the selected packaging format (Tape & Reel or Cut Tape) before procurement.
