Key Parameters

Substitute Part Grouping Explanation

Substitution of the CW02B1K000JS70 is determined by equivalence in the following critical parameters: resistance value (1 kOhms), tolerance (±5%), power rating (3.75W), composition (wirewound), package type (axial), physical dimensions (0.188" Dia x 0.562" L), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). The primary distinction between the main part and its substitute lies in packaging format: the CW02B1K000JS70 is supplied in Tape & Reel (TR) format, while the CW02B1K000JE70 is supplied in Cut Tape (CT) format. Both parts are identical in electrical performance and mechanical specifications, with the packaging difference reflecting distribution and handling requirements rather than functional capability.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW02B1K000JS70 and CW02B1K000JE70 depends on packaging requirements and regulatory compliance needs. Both parts are active products with identical electrical and mechanical specifications. The CW02B1K000JS70 in Tape & Reel format is suitable for high-volume automated assembly operations. The CW02B1K000JE70 in Cut Tape format accommodates lower-volume applications or manual assembly processes. The CW02B1K000JE70 offers ROHS3 compliance and REACH unaffected status, making it the appropriate choice for applications subject to these regulatory requirements. The CW02B1K000JS70 remains suitable for applications where RoHS3 compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can CW02B1K000JE70 be used as a direct replacement for CW02B1K000JS70?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: Tape & Reel versus Cut Tape. Substitution is valid provided the assembly process accommodates the different packaging format.

Q: What is the primary difference between these two parts?

A: The CW02B1K000JS70 is supplied in Tape & Reel (TR) packaging, while the CW02B1K000JE70 is supplied in Cut Tape (CT) packaging. Electrical specifications, physical dimensions, and performance characteristics are identical.

Q: Does packaging format affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical performance and reliability are unaffected by the choice between Tape & Reel and Cut Tape formats.

Q: Which part should be selected for RoHS3-compliant applications?

A: The CW02B1K000JE70 is ROHS3 compliant. The CW02B1K000JS70 is RoHS non-compliant. For applications requiring RoHS3 compliance, CW02B1K000JE70 is the appropriate selection.

Q: Are there inventory considerations when selecting between these parts?

A: The CW02B1K000JS70 has 1160 units in stock, while CW02B1K000JE70 has 926 units in stock. Availability may influence selection based on project timeline and volume requirements.

Q: What is the operating temperature range for both parts?

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