Substitute Part Grouping Explanation

The CW02B330R0JE70 qualifies as a direct electrical and mechanical substitute for the CW02B330R0JS70. Substitution is valid based on the following criteria:

All electrical parameters are identical: 330 Ohm resistance, ±5% tolerance, 3.75W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range.

All mechanical parameters are identical: axial package configuration, 0.188" diameter by 0.562" length, two terminations, and moisture-resistant wirewound construction.

The only difference is packaging format: the main part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) packaging. Both are standard distribution formats for the same component.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between them depends on regulatory and supply chain requirements:

The CW02B330R0JS70 is suitable for applications where RoHS non-compliant components are acceptable and REACH-affected materials are permitted.

The CW02B330R0JE70 is the preferred choice for applications requiring ROHS3 compliance and REACH-unaffected status. This part also offers higher inventory availability (2948 pcs vs. 1100 pcs).

Packaging format selection (Tape & Reel vs. Cut Tape) should be based on assembly equipment compatibility and procurement workflow requirements.

Frequently Asked Questions (FAQ)

Q: Can CW02B330R0JE70 be used as a direct replacement for CW02B330R0JS70?

A: Yes. All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature) and mechanical parameters (package type, dimensions, terminations, composition) are identical. The only difference is packaging format.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for lower-volume or manual assembly processes. Both formats contain the same component.

Q: Are there compliance differences between these parts?

A: Yes. The CW02B330R0JE70 is ROHS3 compliant and REACH unaffected, while the CW02B330R0JS70 is RoHS non-compliant and REACH affected. Select based on your application's regulatory requirements.

Q: Do these parts have identical thermal performance?

A: Yes. Both parts have the same temperature coefficient (±30ppm/°C) and operating temperature range (-65°C to 350°C).

Q: Can packaging format affect circuit performance?

A: No. Packaging format does not affect electrical or thermal performance. Selection should be based on assembly equipment compatibility and supply chain requirements.
