Substitute Part Grouping Explanation

Substitution of the CW02C33R00JS70 is determined by electrical and mechanical parameter equivalence. The primary substitution criterion is maintained across all equivalent parts:

• Resistance value: 33 Ohms
• Tolerance: ±5%
• Power rating: 3.25W
• Composition: Wirewound
• Package case: Axial
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Physical dimensions: 0.218" Dia x 0.500" L (5.54mm x 12.70mm)
• Moisture resistance: Present

Packaging format (tape and reel versus cut tape) represents a supply chain variation and does not affect electrical or mechanical compatibility. RoHS compliance status is an additional differentiator for applications with specific regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The CW02C33R00JE70 is a direct electrical and mechanical equivalent to the CW02C33R00JS70. Both parts maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The primary differences are packaging format and RoHS compliance status.

Selection between these parts depends on application requirements:

• Choose CW02C33R00JS70 when tape and reel packaging is specified for automated assembly processes.
• Choose CW02C33R00JE70 when cut tape packaging is acceptable and ROHS3 compliance is required.

Both parts are active products from Vishay Dale with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CW02C33R00JE70 replace CW02C33R00JS70 in my circuit?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (33 Ohms), tolerance (±5%), power rating (3.25W), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), and physical dimensions (0.218" Dia x 0.500" L). The difference is packaging format and RoHS compliance status.

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 high-speed automated pick-and-place assembly. Cut tape (CT) packaging provides components on individual tape segments, typically for lower-volume applications or manual assembly. Electrically and mechanically, the components are identical.

Q: Does RoHS compliance affect component performance?

A: RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both the RoHS non-compliant CW02C33R00JS70 and ROHS3 compliant CW02C33R00JE70 deliver identical electrical characteristics. Selection depends on regulatory requirements for your end application.

Q: Are there inventory differences between these parts?

A: Yes. CW02C33R00JS70 has 687 units in stock, while CW02C33R00JE70 has 1579 units available. Availability may influence selection for time-sensitive projects.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes, provided your assembly process accommodates the packaging format. If your equipment is configured for tape and reel, use CW02C33R00JS70. If your process uses cut tape, use CW02C33R00JE70. The components are functionally identical.
