Substitute Part Grouping Explanation

Substitution of CW0101K000JS70 is based on electrical and mechanical parameter equivalence within the Vishay Dale CW series. The substitute part CW0101K000JE73 maintains identical electrical specifications: 1 kOhms resistance, ±5% tolerance, 13W power rating, wirewound composition, and moisture-resistant features. Both parts share the same axial package configuration, physical dimensions, temperature coefficient, and operating temperature range. The primary difference between these parts is packaging format: CW0101K000JS70 is supplied in Tape & Reel (TR) format, while CW0101K000JE73 is available in Cut Tape (CT) format. This distinction affects procurement and assembly processes but does not alter component functionality or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

CW0101K000JS70 and CW0101K000JE73 are electrically and mechanically equivalent components suitable for direct substitution in circuit applications requiring 1 kOhms, 13W wirewound axial resistors. Selection between these parts should be based on packaging requirements and regulatory compliance needs. CW0101K000JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental and regulatory requirements. CW0101K000JS70 maintains RoHS non-compliant and REACH affected status. Both parts are active products from Vishay Dale with identical electrical performance characteristics and physical dimensions, ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can CW0101K000JE73 be used as a direct replacement for CW0101K000JS70?

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

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging supplies components on tape segments cut to specific lengths, typically used for lower-volume applications or manual assembly processes. Both formats contain identical components.

Q: Are there compliance differences between these substitute parts?

A: Yes. CW0101K000JE73 is ROHS3 compliant and REACH unaffected, while CW0101K000JS70 is RoHS non-compliant and REACH affected. Applications subject to environmental regulations should specify CW0101K000JE73.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm) and feature identical axial package configuration with two terminations.

Q: What temperature range do these resistors support?

A: Both parts operate from -65°C to 350°C with a temperature coefficient of ±30ppm/°C, providing stable performance across industrial and high-temperature applications.
