Substitute Part Grouping Explanation

The CW0102K000JE73 qualifies as a parametric equivalent to the CW0102K000JS73 based on the following criteria:

All critical electrical parameters are identical: 2 kOhms resistance, ±5% tolerance, 13W power rating, wirewound composition, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range. The physical dimensions and axial package configuration are identical. The primary difference is packaging format: CW0102K000JS73 is supplied in Tape & Reel (TR) format, while CW0102K000JE73 is supplied in Cut Tape (CT) format. Both components are from the same CW series and maintain identical moisture-resistant characteristics and termination configuration.

Parameter Comparison

Engineering Selection Recommendations

Both CW0102K000JS73 and CW0102K000JE73 are Active status components suitable for direct substitution in applications requiring 2 kOhms 13W wirewound axial resistors. The CW0102K000JE73 offers ROHS3 compliance and REACH unaffected status, making it the preferred choice for applications subject to RoHS3 and REACH regulatory requirements. The CW0102K000JS73 remains suitable for applications where RoHS3 compliance is not mandated. Selection between these parts should be based on packaging requirements (Tape & Reel versus Cut Tape) and applicable regulatory compliance standards for the end application.

Frequently Asked Questions (FAQ)

Q: Can CW0102K000JE73 be used as a direct replacement for CW0102K000JS73?

A: Yes. Both components share identical electrical specifications (2 kOhms, ±5%, 13W), thermal characteristics (±30ppm/°C, -65°C to 350°C), physical dimensions (0.375" Dia x 1.781" L), and moisture-resistant wirewound construction. The difference is packaging format only.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for automated assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or smaller production runs.

Q: Does the RoHS3 compliance difference affect electrical performance?

A: No. RoHS3 compliance relates to material composition and regulatory certification, not electrical performance. Both parts deliver identical electrical and thermal characteristics.

Q: Are there inventory considerations when selecting between these parts?

A: Yes. CW0102K000JS73 has 802 pcs in stock, while CW0102K000JE73 has 1996 pcs in stock. Availability may influence selection based on project timeline and quantity requirements.

Q: What applications are suitable for these 13W wirewound resistors?

A: These components are designed for high-power applications requiring stable resistance values across wide temperature ranges. The moisture-resistant construction and -65°C to 350°C operating range support industrial, automotive, and thermal management applications.
