Substitute Part Grouping Explanation

The CW01050R00JE73 qualifies as a direct substitute for the CW01050R00JS73 based on matching electrical and mechanical parameters. Both parts share identical resistance value, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and wirewound moisture-resistant construction. The primary difference between these parts is packaging format: CW01050R00JS73 is supplied in Tape & Reel (TR) configuration, while CW01050R00JE73 is supplied in Cut Tape (CT) configuration. Both packaging types are standard industry formats for through-hole axial resistors and do not affect component functionality or performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CW01050R00JS73 and CW01050R00JE73 are active production components from Vishay Dale with identical electrical performance and physical dimensions. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The CW01050R00JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental regulations. The CW01050R00JS73 maintains RoHS non-compliant status but is available in Tape & Reel format for automated assembly processes. Both parts are functionally interchangeable in circuit design and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CW01050R00JE73 replace CW01050R00JS73 in my circuit design? A: Yes. Both parts have identical electrical specifications (50 Ohms, ±5%, 13W), temperature characteristics (±30ppm/°C, -65°C to 350°C), and physical dimensions (0.375" Dia x 1.781" L). They are functionally equivalent for all circuit applications.

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, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for lower-volume or manual assembly processes. Both formats contain identical components with no functional difference.

Q: Does the packaging format affect component performance? A: No. Packaging format affects only handling, storage, and assembly processes. Electrical performance, temperature characteristics, and reliability are identical regardless of whether the component is supplied in Tape & Reel or Cut Tape format.

Q: What are the compliance differences between these parts? A: CW01050R00JE73 is ROHS3 compliant and REACH unaffected, while CW01050R00JS73 is RoHS non-compliant and REACH affected. For applications requiring environmental compliance certification, CW01050R00JE73 is the appropriate selection.

Q: Are both parts currently in production? A: Yes. Both CW01050R00JS73 and CW01050R00JE73 maintain active product status with Vishay Dale. CW01050R00JE73 has higher inventory availability (2314 units) compared to CW01050R00JS73 (791 units).
