Substitute Part Grouping Explanation

Substitution between CW0104K000JS73 and CW0104K000JE73 is based on electrical and mechanical parameter equivalence. Both parts share identical resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, physical dimensions, and termination count. The primary distinction is packaging format: CW0104K000JS73 is supplied in Tape & Reel (TR) format, while CW0104K000JE73 is supplied in Cut Tape (CT) format. This packaging difference does not affect electrical performance or mechanical compatibility in circuit applications. Substitution is valid when packaging format flexibility is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

Both CW0104K000JS73 and CW0104K000JE73 are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and regulatory compliance needs. CW0104K000JE73 offers ROHS3 compliance and REACH unaffected status, providing advantages for applications subject to environmental regulations. CW0104K000JS73 in Tape & Reel format is suitable for high-volume automated assembly processes, while CW0104K000JE73 in Cut Tape format accommodates lower-volume or manual assembly workflows. Inventory availability should also be considered: CW0104K000JE73 currently maintains higher stock levels at 1739 pieces compared to 655 pieces for CW0104K000JS73.

Frequently Asked Questions (FAQ)

Q: Can CW0104K000JE73 be used as a direct replacement for CW0104K000JS73?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The only difference is packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance or board compatibility.

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-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume assembly or manual handling.

Q: Are there compliance differences between these parts?

A: Yes. CW0104K000JE73 is ROHS3 compliant and REACH unaffected, while CW0104K000JS73 is RoHS non-compliant and REACH affected. Applications requiring environmental compliance should specify CW0104K000JE73.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts operate from -65°C to 350°C with identical temperature coefficient of ±30ppm/°C, ensuring equivalent thermal stability across the full operating range.

Q: Which part should be selected for new designs?

A: CW0104K000JE73 is recommended for new designs due to ROHS3 compliance and REACH unaffected status, providing better long-term regulatory alignment and supply chain sustainability.
