Substitute Part Grouping Explanation

The CW005R5000JE73 qualifies as a direct substitute for the CW005R5000JS73 based on matching electrical and mechanical parameters. Both parts share identical resistance value, tolerance, power rating, composition, package type, physical dimensions, temperature coefficient, and operating temperature range. The substitution is valid across all functional and thermal performance criteria. The primary difference is packaging format: CW005R5000JS73 is supplied in Tape & Reel (TR) configuration, while CW005R5000JE73 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 CW005R5000JS73 and CW005R5000JE73 are active production components suitable for direct substitution in circuit designs requiring 500 mOhms ±5% 6.5W axial wirewound resistors. Selection between these parts should be based on procurement and assembly requirements. The CW005R5000JS73 in Tape & Reel packaging is optimized for high-volume automated assembly processes. The CW005R5000JE73 in Cut Tape packaging provides flexibility for lower-volume applications or manual assembly workflows. Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. Compliance considerations differ: CW005R5000JS73 is RoHS non-compliant and REACH Affected, while CW005R5000JE73 is ROHS3 Compliant and REACH Unaffected. Applications requiring specific regulatory compliance should reference these certifications during part selection.

Frequently Asked Questions (FAQ)

Q: Can CW005R5000JE73 be used as a direct replacement for CW005R5000JS73 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance or component functionality.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Are there any thermal performance differences between these substitute parts?

A: No. Both parts have identical temperature coefficients (±90ppm/°C) and operating temperature ranges (-65°C ~ 350°C). Thermal performance is equivalent across all operating conditions.

Q: Do compliance certifications affect substitution eligibility?

A: Compliance certifications do not affect electrical or mechanical substitution. However, applications subject to RoHS or REACH regulations must select the appropriate part variant. CW005R5000JE73 meets ROHS3 and REACH Unaffected requirements, while CW005R5000JS73 does not. Verify regulatory requirements for your specific application before final part selection.

Q: What inventory considerations apply to these substitute parts?

A: CW005R5000JS73 has 970 pieces in stock, while CW005R5000JE73 has 1687 pieces available. Inventory levels may influence procurement decisions for time-sensitive applications.
