Substitute Part Grouping Explanation

Substitution for the CW02B180R0JS70 is determined by strict equivalence across the following critical parameters: resistance value (180 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 the main part and its substitute lies in packaging format (Tape & Reel versus Cut Tape) and regulatory compliance status. Both parts maintain identical electrical performance and mechanical compatibility within the same series (CW).

Engineering Selection Recommendations

The CW02B180R0JE70 serves as a direct parametric equivalent to the CW02B180R0JS70, with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The CW02B180R0JS70 is supplied in Tape & Reel format and carries RoHS non-compliant and REACH Affected status. The CW02B180R0JE70 is supplied in Cut Tape format and is ROHS3 Compliant with REACH Unaffected status. Both parts are active products from Vishay Dale's CW series. Applications requiring ROHS3 compliance or REACH compliance should specify the CW02B180R0JE70. Applications with Tape & Reel packaging requirements should specify the CW02B180R0JS70.

Frequently Asked Questions (FAQ)

Q: Can CW02B180R0JE70 be used as a direct replacement for CW02B180R0JS70?

A: Yes. Both parts are electrically and mechanically identical with 180 Ohm resistance, ±5% tolerance, 3.75W power rating, and identical physical dimensions. The difference is packaging format (Cut Tape versus Tape & Reel) and regulatory compliance status.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, suitable for automated assembly equipment. Cut Tape packaging supplies the same components on cut sections of carrier tape, suitable for manual handling or smaller volume applications. Electrical and mechanical performance is identical.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and regulatory requirements, not electrical performance. Both parts deliver identical resistance, tolerance, power rating, and temperature characteristics.

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

A: Yes. Both CW02B180R0JS70 and CW02B180R0JE70 operate across -65°C to 350°C with ±30ppm/°C temperature coefficient, making them suitable for high-temperature circuit applications.

Q: Which part should be selected for new designs?

A: Selection depends on specific requirements. For applications requiring ROHS3 and REACH compliance, specify CW02B180R0JE70. For applications with existing Tape & Reel supply chain integration, specify CW02B180R0JS70. Both are active products with adequate inventory.
