Substitute Part Grouping Explanation

The CW02B470R0JE70 qualifies as a parametric equivalent to the CW02B470R0JS70 based on identical electrical and mechanical specifications. Both parts share the same resistance value (470 Ohms), tolerance (±5%), power rating (3.75W), composition (wirewound), package type (axial), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), physical dimensions (0.188" Dia x 0.562" L), and moisture-resistant features. The primary difference between these parts is packaging format: the main part is supplied in tape and reel (TR) configuration, while the substitute is supplied in cut tape (CT) configuration. Both parts are manufactured by Vishay Dale within the CW series and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CW02B470R0JE70 serves as a direct electrical and mechanical substitute for the CW02B470R0JS70. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The main part (CW02B470R0JS70) in tape and reel format is suitable for high-volume automated assembly processes. The substitute part (CW02B470R0JE70) in cut tape format provides greater inventory availability and offers improved compliance status: it is ROHS3 compliant and REACH unaffected, compared to the main part which is RoHS non-compliant and REACH affected. For applications subject to RoHS3 or REACH regulations, the CW02B470R0JE70 is the appropriate selection. Both parts maintain identical electrical performance and are suitable for applications requiring moisture-resistant wirewound resistors across extended temperature ranges.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically identical? A: Yes. Both the CW02B470R0JS70 and CW02B470R0JE70 have identical resistance (470 Ohms), tolerance (±5%), power rating (3.75W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C).

Q: What is the difference between tape and reel and cut tape packaging? A: Tape and reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape (CT) packaging supplies components on individual tape segments, typically used for manual assembly or lower-volume applications.

Q: Can I use the CW02B470R0JE70 as a direct replacement for the CW02B470R0JS70? A: Yes, provided your assembly process can accommodate cut tape packaging instead of tape and reel format. Electrically and mechanically, both parts are identical.

Q: What compliance differences exist between these parts? A: The CW02B470R0JE70 is ROHS3 compliant and REACH unaffected, while the CW02B470R0JS70 is RoHS non-compliant and REACH affected. For applications requiring RoHS3 or REACH compliance, the CW02B470R0JE70 must be selected.

Q: Are the physical dimensions identical? A: Yes. Both parts have identical axial package dimensions of 0.188" diameter by 0.562" length (4.78mm x 14.27mm).

Q: Which part has better inventory availability? A: The CW02B470R0JE70 has 2502 units in stock compared to 1046 units for the CW02B470R0JS70.
