CW005270R0JS73 Equivalent & Substitute Parts

Part Overview

The CW005270R0JS73 is a 270 Ohm, 6.5W wirewound axial 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 active in production and available in Tape & Reel packaging. Substitute parts are identified when packaging format changes or when compliance requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The CW005270R0JE73 qualifies as a direct substitute based on identical electrical and mechanical parameters: 270 Ohm resistance, ±5% tolerance, 6.5W power rating, wirewound composition, axial package configuration, and matching physical dimensions (0.312" Dia x 0.875" L). The primary distinction between these parts is packaging format: CW005270R0JS73 is supplied in Tape & Reel (TR) configuration, while CW005270R0JE73 is supplied in Cut Tape (CT) configuration. Both parts maintain the same temperature coefficient (±30ppm/°C), operating temperature range (-65°C ~ 350°C), and moisture-resistant features. The substitution is valid when packaging format compatibility permits the change.

Parameter Comparison

Engineering Selection Recommendations

Both CW005270R0JS73 and CW005270R0JE73 are active production parts from Vishay Dale with identical electrical performance and mechanical compatibility. Selection between these parts depends on packaging requirements and compliance mandates. The CW005270R0JE73 offers ROHS3 compliance and REACH unaffected status, whereas the CW005270R0JS73 is RoHS non-compliant and REACH affected. When regulatory compliance with ROHS3 standards is required, the CW005270R0JE73 is the appropriate selection. When Tape & Reel packaging is specifically mandated by assembly processes, the CW005270R0JS73 remains the correct choice. Both parts are functionally interchangeable from an electrical and thermal standpoint.

Frequently Asked Questions (FAQ)

Q: Can CW005270R0JE73 replace CW005270R0JS73 in my circuit?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical resistance (270 Ohms), tolerance (±5%), power rating (6.5W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). The primary difference is packaging format: Tape & Reel versus Cut Tape. Verify your assembly equipment can accommodate the Cut Tape format before substitution.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides components on tape segments, typically for manual assembly or lower-volume production. Both formats contain the same component with identical specifications.

Q: Does the CW005270R0JE73 have better compliance than the main part?

A: The CW005270R0JE73 is ROHS3 compliant and REACH unaffected, while the CW005270R0JS73 is RoHS non-compliant and REACH affected. If your application or region requires ROHS3 compliance, the CW005270R0JE73 is the appropriate selection.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical axial package dimensions of 0.312" Dia x 0.875" L (7.92mm x 22.22mm), ensuring mechanical compatibility in PCB layouts and through-hole assembly.

Q: Can I use these parts interchangeably in high-temperature applications?

A: Yes. Both parts operate across the same temperature range (-65°C ~ 350°C) with identical temperature coefficient (±30ppm/°C), making them functionally equivalent for thermal performance.
