CW01010R00JS73 Equivalent & Substitute Parts

Part Overview

The CW01010R00JS73 is a 10 Ohm, 13W wirewound axial resistor manufactured by Vishay Dale. 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 is currently in active production status with 1106 units available 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 performance.

Substitute Part Grouping Explanation

Substitution of the CW01010R00JS73 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.375" Dia x 1.781" L
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Moisture resistance feature
• Two terminations

The CW01010R00JE73 meets all electrical and mechanical requirements for direct substitution. The primary difference between the main part and its substitute is the packaging format: the original uses Tape & Reel (TR) configuration, while the substitute uses Cut Tape (CT) configuration. Both formats contain identical components with no functional or performance differences.

Engineering Selection Recommendations

The CW01010R00JE73 is a direct electrical and mechanical equivalent to the CW01010R00JS73. Selection between these parts should be based on the following factors:

Packaging Requirements: Choose CW01010R00JS73 when Tape & Reel packaging is required for automated assembly processes. Select CW01010R00JE73 when Cut Tape packaging is acceptable or preferred for manual assembly or lower-volume applications.

Compliance Requirements: The CW01010R00JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental and regulatory requirements. The CW01010R00JS73 is RoHS non-compliant and REACH affected, requiring evaluation against specific application compliance mandates.

Inventory Availability: The CW01010R00JE73 has significantly higher inventory availability (3589 units) compared to the CW01010R00JS73 (1106 units), making it the preferred choice for applications with extended lead time requirements or high-volume procurement needs.

Both parts are active products from Vishay Dale and maintain identical electrical performance characteristics across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can CW01010R00JE73 be used as a direct replacement for CW01010R00JS73?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (10 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), physical dimensions (0.375" Dia x 1.781" L), and moisture-resistant wirewound construction. The only difference is packaging format: Tape & Reel versus Cut Tape.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging provides the same components on shorter tape segments, suitable for manual assembly, lower-volume production, or applications where reel handling is impractical.

Q: Are there any performance differences between these two parts?

A: No. Both parts deliver identical electrical performance. Resistance accuracy, power dissipation capability, temperature stability, and operating range are equivalent across all specified conditions.

Q: Which part should I select for new designs?

A: Selection depends on assembly method and compliance requirements. For automated assembly with Tape & Reel capability, either part is suitable based on compliance needs. For manual assembly or lower volumes, CW01010R00JE73 with Cut Tape packaging is appropriate. If ROHS3 and REACH compliance are mandatory, CW01010R00JE73 is required.

Q: Are both parts currently in production?

A: Yes. Both CW01010R00JS73 and CW01010R00JE73 maintain active production status with Vishay Dale.
