Substitute Part Grouping Explanation

The CW02B270R0JE70 qualifies as a direct substitute for the CW02B270R0JS70 based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical selection criteria: 270 Ohm resistance value, ±5% tolerance, 3.75W power rating, wirewound composition, axial package configuration, ±30ppm/°C temperature coefficient, -65°C to 350°C operating temperature range, moisture-resistant features, and identical physical dimensions (0.188" Dia x 0.562" L).

The primary difference between these parts is packaging format: CW02B270R0JS70 is supplied in Tape & Reel (TR) format, while CW02B270R0JE70 is supplied in Cut Tape (CT) format. This distinction affects only the procurement and handling process, not the electrical or mechanical performance of the component itself.

Parameter Comparison

Engineering Selection Recommendations

Both CW02B270R0JS70 and CW02B270R0JE70 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on manufacturing process requirements and packaging handling capabilities.

CW02B270R0JS70 in Tape & Reel format is suitable for high-volume automated assembly processes where continuous reel feeding is required. CW02B270R0JE70 in Cut Tape format is appropriate for lower-volume production runs, manual assembly operations, or applications where individual component handling is preferred.

Both parts are RoHS non-compliant and REACH Affected, with identical compliance status. Inventory availability shows CW02B270R0JE70 with 1401 units in stock compared to 1034 units for CW02B270R0JS70, providing additional procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can CW02B270R0JE70 be used as a direct replacement for CW02B270R0JS70 in circuit design?

A: Yes. Both parts have identical electrical and mechanical specifications including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The only difference is packaging format, which does not affect circuit performance.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides components on tape segments, typically used for manual assembly or lower-volume production. Both formats contain the same component.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant) and REACH status (Affected). Compliance characteristics are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process requirements. For automated assembly with reel-fed equipment, use CW02B270R0JS70. For manual assembly or lower-volume applications, use CW02B270R0JE70. Both are active production parts with equivalent performance.

Q: Can these parts be intermixed in the same assembly?

A: Yes. Since electrical and mechanical specifications are identical, these parts can be used interchangeably within the same assembly. Packaging format differences do not affect component functionality or circuit performance.
