Key Parameters

Substitute Part Grouping Explanation

The CW0052R000JE73 qualifies as a direct substitute for the CW0052R000JS73 based on matching electrical and mechanical parameters. Both parts share identical resistance value (2 Ohms), tolerance (±5%), power rating (6.5W), composition (wirewound), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 350°C), and physical dimensions (0.312" Dia x 0.875" L). The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both are manufactured by Vishay Dale within the CW series.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW0052R000JS73 and CW0052R000JE73 depends on packaging requirements and regulatory compliance needs. The CW0052R000JS73 in Tape & Reel format is suitable for high-volume automated assembly processes. The CW0052R000JE73 in Cut Tape format accommodates lower-volume applications or manual assembly workflows. For applications requiring RoHS3 compliance and REACH unaffected status, the CW0052R000JE73 is the appropriate choice. Both parts maintain identical electrical performance and thermal characteristics across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. Both parts have identical resistance (2 Ohms), tolerance (±5%), power rating (6.5W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 350°C).

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 automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume production.

Q: Can I use CW0052R000JE73 as a direct replacement for CW0052R000JS73? A: Yes, provided your assembly process accommodates Cut Tape format. The electrical and mechanical specifications are identical.

Q: What is the significance of RoHS3 compliance? A: RoHS3 compliance indicates the CW0052R000JE73 meets Restriction of Hazardous Substances regulations. The CW0052R000JS73 is RoHS non-compliant. Selection depends on regulatory requirements for your application.

Q: Are the physical dimensions identical? A: Dimensions are effectively identical: both measure 0.312" Dia x 0.875" L. The CW0052R000JE73 shows 22.23mm length versus 22.22mm for the CW0052R000JS73, a negligible 0.01mm difference within manufacturing tolerance.

Q: Which part should I select for new designs? A: Base selection on packaging requirements and compliance mandates. For RoHS3-compliant applications, use CW0052R000JE73. For Tape & Reel automated assembly, use CW0052R000JS73.
