Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW02B50R00JS70 is determined by matching the following critical parameters:

• Resistance value: 50 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 to 350°C
• Features: Moisture Resistant

The identified substitute part CW02B50R00JE70 matches all electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. Both formats contain identical components suitable for through-hole PCB assembly applications.

Parameter Comparison

Engineering Selection Recommendations

Both CW02B50R00JS70 and CW02B50R00JE70 are electrically and mechanically equivalent and suitable for direct substitution in through-hole PCB applications requiring 50 Ohm, 3.75W wirewound resistors.

Selection between these parts should be based on:

• Packaging format requirements: Choose TR format for automated reel-fed assembly; choose CT format for manual or semi-automated placement
• Compliance requirements: CW02B50R00JE70 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with regulatory compliance mandates
• Inventory availability: CW02B50R00JE70 has higher stock levels (2547 units vs. 795 units)
• Supply chain considerations: Both parts are active products from the same manufacturer and series

Frequently Asked Questions (FAQ)

Q: Can CW02B50R00JE70 be used as a direct replacement for CW02B50R00JS70?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The only difference is packaging format (Cut Tape vs. Tape & Reel).

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

A: Tape & Reel (TR) format supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) format supplies components on tape segments, typically used for manual assembly or lower-volume production runs.

Q: Does the packaging format affect component performance?

A: No. The component itself is identical regardless of packaging format. Performance characteristics, electrical specifications, and reliability are unchanged.

Q: Why would I choose the substitute part over the main part?

A: CW02B50R00JE70 offers higher inventory availability, ROHS3 compliance, and REACH unaffected status. These factors may be relevant for regulatory compliance, supply chain continuity, or specific procurement requirements.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the full temperature range of -65°C to 350°C with a temperature coefficient of ±30ppm/°C, making them suitable for demanding thermal environments.

Q: What is the significance of RoHS and REACH compliance differences?

A: CW02B50R00JE70 meets ROHS3 compliance and is REACH unaffected, indicating it meets current European Union environmental and chemical safety regulations. CW02B50R00JS70 does not meet these standards. Selection depends on end-market regulatory requirements.
