CW0051K500JS73 Equivalent & Substitute Parts

Part Overview

The CW0051K500JS73 is a 1.5 kOhms ±5% 6.5W through-hole resistor manufactured by Vishay Dale in the CW series. This axial wirewound resistor features moisture-resistant construction and operates across a wide temperature range from -65°C to 350°C. The part is currently active in production with 923 units in stock. Substitute parts are necessary when tape and reel packaging is unavailable or when RoHS3 compliance is required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

The CW0051K500JE73 qualifies as a direct substitute for the CW0051K500JS73 based on the following critical parameters:

• Identical resistance value: 1.5 kOhms
• Identical tolerance: ±5%
• Identical power rating: 6.5W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±30ppm/°C
• Identical operating temperature range: -65°C to 350°C
• Identical moisture-resistant feature
• Identical number of terminations: 2
• Equivalent dimensions: 0.312" Dia x 0.875" L (7.92mm x 22.23mm)

The primary difference between these parts is packaging format: the main part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) packaging. Both parts are manufactured by Vishay Dale within the CW series and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CW0051K500JS73 and CW0051K500JE73 are active production parts suitable for equivalent circuit applications. Selection between these parts should be based on the following criteria:

CW0051K500JS73 (Tape & Reel): Use when tape and reel packaging is required for automated assembly processes and RoHS non-compliance is acceptable for the application.

CW0051K500JE73 (Cut Tape): Use when cut tape packaging is suitable for manual assembly or when ROHS3 compliance and REACH unaffected status are required. This part also offers higher inventory availability at 1651 units.

Both parts maintain identical electrical performance and mechanical compatibility across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Are CW0051K500JS73 and CW0051K500JE73 electrically identical?

A: Yes. Both parts have identical resistance (1.5 kOhms), tolerance (±5%), power rating (6.5W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C).

Q: What is the difference between these two parts?

A: The primary difference is packaging format. CW0051K500JS73 uses Tape & Reel (TR) packaging, while CW0051K500JE73 uses Cut Tape (CT) packaging. Additionally, CW0051K500JE73 is ROHS3 compliant and REACH unaffected, whereas CW0051K500JS73 is RoHS non-compliant and REACH affected.

Q: Can I use CW0051K500JE73 as a direct replacement for CW0051K500JS73?

A: Yes, for applications where packaging format and compliance requirements are compatible. Verify that your assembly process can accommodate cut tape packaging and that RoHS3 compliance is acceptable or required.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent. CW0051K500JS73 measures 0.312" Dia x 0.875" L (7.92mm x 22.22mm), while CW0051K500JE73 measures 0.312" Dia x 0.875" L (7.92mm x 22.23mm). The 0.01mm difference in length is within manufacturing tolerance and does not affect mechanical compatibility.

Q: Which part should I select for new designs?

A: Selection depends on assembly requirements and compliance mandates. For automated tape and reel assembly, use CW0051K500JS73. For manual assembly or when ROHS3 compliance is required, use CW0051K500JE73.
