CW005390R0JS73 Equivalent & Substitute Parts

Part Overview

The CW005390R0JS73 is a 390 Ohm, 6.5W axial wirewound resistor manufactured by Vishay Dale. This through-hole component features moisture-resistant construction and operates across a wide temperature range from -65°C to 350°C. The part is currently in active production status. Substitute parts are identified when packaging format changes or when compliance requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The CW005390R0JE73 qualifies as a direct substitute for the CW005390R0JS73 based on matching electrical and mechanical parameters. Both parts share identical resistance value (390 Ohms), tolerance (±5%), power rating (6.5W), composition (wirewound), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), and physical dimensions (0.312" Dia x 0.875" L). The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. This distinction affects procurement and assembly processes but does not alter component performance or compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CW005390R0JS73 and CW005390R0JE73 are active production components from Vishay Dale with identical electrical performance and mechanical compatibility. Selection between these parts depends on procurement and assembly requirements rather than circuit performance.

The CW005390R0JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with regulatory compliance requirements. The CW005390R0JS73 remains available for applications where RoHS non-compliance is acceptable and REACH affected status is permissible.

Packaging format differences (Tape & Reel versus Cut Tape) affect handling and assembly processes. Tape & Reel packaging is optimized for high-volume automated assembly, while Cut Tape packaging accommodates lower-volume or manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can CW005390R0JE73 be used as a direct replacement for CW005390R0JS73?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (390 Ohms), tolerance (±5%), power rating (6.5W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C). The only difference is packaging format and compliance certifications.

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 cut to specific lengths, suitable for manual assembly or lower-volume production.

Q: Does the CW005390R0JE73 have better compliance status?

A: The CW005390R0JE73 is ROHS3 compliant and REACH unaffected, while the CW005390R0JS73 is RoHS non-compliant and REACH affected. Selection depends on regulatory requirements for your application.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are effectively identical. Both parts measure 0.312" diameter by 0.875" length (7.92mm x 22.22mm/22.23mm). The negligible difference in length (0.01mm) is within manufacturing tolerance and does not affect circuit board layout or mechanical fit.

Q: Which part should I select for new designs?

A: Selection is based on compliance requirements and assembly process. For applications requiring RoHS3 compliance and REACH unaffected status, use CW005390R0JE73. For applications without these requirements, either part is suitable based on packaging needs.
