Substitute Part Grouping Explanation

The CW005120R0JE73 qualifies as a direct substitute for the CW005120R0JS73 based on identical electrical and mechanical parameters. Both parts share the same resistance value (120 Ohms), tolerance (±5%), power rating (6.5W), composition (wirewound), package type (axial), physical dimensions (0.312" Dia x 0.875" L), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). The primary difference between these parts is packaging format: CW005120R0JS73 is supplied in tape and reel (TR) configuration, while CW005120R0JE73 is supplied in cut tape (CT) configuration. Both parts maintain the moisture-resistant feature and two-termination design required for equivalent functionality.

Parameter Comparison

Engineering Selection Recommendations

The CW005120R0JE73 serves as a functional equivalent to the CW005120R0JS73 for applications where electrical and thermal performance specifications are identical. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The CW005120R0JS73 in tape and reel format is suitable for high-volume automated assembly processes. The CW005120R0JE73 in cut tape format provides flexibility for lower-volume applications or manual assembly workflows. The CW005120R0JE73 offers improved compliance status with ROHS3 certification and REACH unaffected designation, making it preferable for applications subject to environmental regulations. Both parts maintain active production status and are available in adequate inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can CW005120R0JE73 replace CW005120R0JS73 in my circuit design?

A: Yes. Both parts are electrically and mechanically identical with 120 Ohm resistance, ±5% tolerance, 6.5W power rating, and identical physical dimensions. The only difference is packaging format (cut tape versus tape and reel).

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape packaging supplies components on individual tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain the same component.

Q: Are there compliance differences between these parts?

A: Yes. The CW005120R0JE73 is ROHS3 compliant and REACH unaffected, while the CW005120R0JS73 is RoHS non-compliant and REACH affected. Applications subject to environmental or regulatory requirements should specify the CW005120R0JE73.

Q: Do these parts have identical thermal performance?

A: Yes. Both parts share the same temperature coefficient (±30ppm/°C) and operating temperature range (-65°C ~ 350°C), ensuring identical thermal stability and performance across the specified operating envelope.

Q: Can I use CW005120R0JE73 in high-volume automated assembly?

A: Cut tape packaging is not optimized for high-speed automated assembly. For high-volume production, the CW005120R0JS73 in tape and reel format is the appropriate choice. The CW005120R0JE73 is better suited for manual assembly or lower-volume applications.
