Substitute Part Grouping Explanation

Substitution between CW02B2K700JS70 and CW02B2K700JE70 is valid based on the following criteria:

Both parts share identical electrical specifications: 2.7 kOhms resistance, ±5% tolerance, 3.75W power rating, wirewound composition, and ±30ppm/°C temperature coefficient. Both maintain the same operating temperature range (-65°C to 350°C) and physical dimensions (0.188" Dia x 0.562" L). The primary difference is packaging format: CW02B2K700JS70 is supplied in Tape & Reel (TR) format, while CW02B2K700JE70 is supplied in Cut Tape (CT) format. This distinction affects procurement and assembly processes but does not impact electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW02B2K700JS70 and CW02B2K700JE70 should be based on packaging requirements and regulatory compliance needs. Both parts are Active status products with identical electrical and mechanical performance. CW02B2K700JE70 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental regulations. CW02B2K700JS70 in Tape & Reel format is appropriate for high-volume automated assembly processes, while CW02B2K700JE70 in Cut Tape format accommodates lower-volume or manual assembly workflows. The choice does not affect circuit performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can CW02B2K700JE70 be used as a direct replacement for CW02B2K700JS70?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values, tolerances, power ratings, temperature coefficients, and operating ranges. The substitution is valid from a functional standpoint. Packaging format differences (Tape & Reel versus Cut Tape) affect procurement and assembly logistics but not component performance.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments cut to specific lengths, suitable for lower-volume production or manual assembly operations. Both formats contain identical components.

Q: Are there compliance differences between these parts?

A: Yes. CW02B2K700JE70 is ROHS3 compliant and REACH unaffected, while CW02B2K700JS70 is RoHS non-compliant and REACH affected. Applications subject to environmental regulations should specify CW02B2K700JE70.

Q: Do these resistors have identical thermal performance?

A: Yes. Both parts share the same temperature coefficient (±30ppm/°C) and operating temperature range (-65°C to 350°C), ensuring identical thermal behavior in circuit applications.

Q: Can packaging format affect circuit reliability?

A: No. Packaging format does not impact electrical performance, reliability, or thermal characteristics. The component itself remains unchanged; only the delivery and handling format differs.
