CW0057R500JS73 Equivalent & Substitute Parts

Part Overview

The CW0057R500JS73 is a 7.5 Ohm, 6.5W wirewound axial resistor manufactured by Vishay Dale, part of the CW series. This component is designed for through-hole applications requiring moisture-resistant performance across an extended operating temperature range of -65°C to 350°C. The part maintains active product status with 1076 units currently in stock.

Identifying equivalent and substitute parts is necessary when the original packaging format (Tape & Reel) is unavailable, when alternative compliance certifications are required, or when inventory constraints necessitate sourcing from alternative packaging configurations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CW0057R500JS73 is determined by strict equivalence across the following critical parameters:

• Resistance value: 7.5 Ohms
• Tolerance: ±5%
• Power rating: 6.5W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.312" Dia x 0.875" L (7.92mm x 22.22mm)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C ~ 350°C
• Moisture resistance feature
• Number of terminations: 2

The CW0057R500JE73 qualifies as a direct substitute based on identical electrical specifications and mechanical dimensions. The primary difference lies in packaging format: the substitute is supplied in Cut Tape (CT) configuration rather than Tape & Reel (TR), and carries different compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CW0057R500JE73 serves as a direct electrical and mechanical equivalent to the CW0057R500JS73. Both components deliver identical performance across all specified electrical parameters and physical dimensions.

Selection between these parts should be based on:

• Packaging requirements: Choose Tape & Reel (TR) format for automated assembly processes; select Cut Tape (CT) for manual assembly or lower-volume applications.
• Compliance requirements: The CW0057R500JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with stricter environmental regulations. The CW0057R500JS73 is RoHS non-compliant and REACH affected.
• Inventory availability: The CW0057R500JE73 currently maintains higher stock levels (1447 units versus 1076 units).

Both parts maintain active product status and are manufactured by Vishay Dale within the CW series.

Frequently Asked Questions (FAQ)

Q: Can CW0057R500JE73 be used as a direct replacement for CW0057R500JS73 in circuit design?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values (7.5 Ohms ±5%), power ratings (6.5W), temperature coefficients (±50ppm/°C), operating ranges (-65°C ~ 350°C), and physical dimensions (0.312" Dia x 0.875" L). The substitute will function identically in any circuit application.

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, optimized for high-speed automated assembly equipment. Cut Tape (CT) packaging provides components on tape segments, suitable for manual assembly, lower-volume production, or applications where reel-based handling is not required. Both formats contain the same component.

Q: Are there compliance differences between these parts?

A: Yes. The CW0057R500JE73 is ROHS3 compliant and REACH unaffected, while the CW0057R500JS73 is RoHS non-compliant and REACH affected. Applications subject to environmental compliance mandates should specify the CW0057R500JE73.

Q: Do both parts have the same moisture resistance rating?

A: Yes. Both the CW0057R500JS73 and CW0057R500JE73 feature moisture-resistant construction and are rated for identical operating conditions across the -65°C to 350°C temperature range.

Q: Which part should be selected for new designs?

A: Selection depends on packaging infrastructure and compliance requirements. For automated assembly with environmental compliance mandates, the CW0057R500JE73 (Cut Tape, ROHS3 compliant) is appropriate. For manual assembly or applications without strict compliance requirements, either part is suitable based on packaging preference and inventory availability.
