Key Parameters

Substitute Part Grouping Explanation

Strict substitution is only possible when the following parameters are equivalent: resistance, tolerance, power rating, composition, features, temperature coefficient, operating temperature range, package/case, supplier device package, size/dimension, and number of terminations. Compliance status is also considered as it affects suitability for regulated applications. Alternative packaging (Tape & Reel vs Cut Tape) does not impact electrical or mechanical interchangeability but may be relevant for production processes.

Parameter Comparison

Engineering Selection Recommendations

Both CW0103K300JS73 and CW0103K300JE73 are active and provide equivalent electrical and mechanical performance according to the listed key parameters. Selection between these parts can be based on compliance requirements: CW0103K300JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for environments requiring restricted hazardous substance certification. Packaging differences do not affect form, fit, or function.

Frequently Asked Questions (FAQ)

Q: What parameters must be identical for substitution of axial wirewound resistors in this category?
A: Resistance, tolerance, power rating, composition, features, temperature coefficient, operating temperature range, package/case, supplier device package, size/dimension, and number of terminations must match.

Q: Does packaging format affect substitution for through-hole resistors in production?
A: Packaging format (Tape & Reel versus Cut Tape) does not influence electrical or mechanical compatibility but may impact automated assembly preferences.

Q: How do RoHS and REACH compliance impact substitute selection?
A: RoHS and REACH statuses are critical for regulatory and environmental conformity. ROHS3 compliant and REACH unaffected substitutes are required for certain applications subject to compliance regulation.

Q: Is there any change in physical size or mounting between CW0103K300JS73 and CW0103K300JE73?
A: No, both parts share the same axial package, dimensions, and terminations according to provided specifications.

Q: Are both parts currently available according to the input inventory status?
A: Both CW0103K300JS73 and CW0103K300JE73 are listed as active and available in stock.
