Substitute Part Grouping Explanation

Substitution for the CW02B10R00JS70 is determined by equivalence in the following critical parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 3.75W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.188" Dia x 0.562" L
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C ~ 350°C
• Moisture resistance feature

The primary variable between the main part and its substitute is the packaging format (Tape & Reel versus Cut Tape), which affects supply chain logistics but does not alter electrical or mechanical performance. Compliance status differences are noted for applications with specific regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both CW02B10R00JS70 and CW02B10R00JE70 are electrically and mechanically identical, with all critical performance parameters matching exactly. Selection between these parts depends on application-specific requirements:

For applications requiring ROHS3 compliance and REACH unaffected status, the CW02B10R00JE70 is the appropriate selection. This part maintains full electrical equivalence while meeting enhanced regulatory requirements.

For applications where RoHS non-compliance is acceptable and REACH affected status is permissible, the CW02B10R00JS70 remains a valid choice with higher current inventory availability.

The packaging format difference (Tape & Reel versus Cut Tape) affects procurement and assembly processes but does not impact circuit performance or component functionality.

Frequently Asked Questions (FAQ)

Q: Are CW02B10R00JS70 and CW02B10R00JE70 electrically interchangeable?

A: Yes. Both parts have identical resistance (10 Ohms), tolerance (±5%), power rating (3.75W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). They are direct electrical equivalents.

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 automated assembly lines. Cut Tape (CT) packaging provides components on tape segments cut to specified lengths, suitable for manual assembly or smaller production runs. Both formats contain identical components.

Q: Can I use CW02B10R00JE70 as a direct replacement for CW02B10R00JS70 in my circuit?

A: Yes, provided your application does not have specific packaging format requirements. The electrical and mechanical specifications are identical, allowing direct substitution in the circuit design.

Q: Why would I choose CW02B10R00JE70 over CW02B10R00JS70?

A: Choose CW02B10R00JE70 if your application or supply chain requires ROHS3 compliance or REACH unaffected status. This part also has higher inventory availability (2052 units versus 1144 units).

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.188" diameter by 0.562" length (4.78mm x 14.27mm), ensuring identical PCB footprint and mounting requirements.

Q: What compliance certifications differ between these parts?

A: CW02B10R00JS70 is RoHS non-compliant and REACH affected. CW02B10R00JE70 is ROHS3 compliant and REACH unaffected. Select based on your regulatory requirements.
