Key Parameters

Substitute Part Grouping Explanation

Substitution for the CW0102K700JS73 is determined by exact matching of key electrical and mechanical parameters: resistance value (2.7 kOhms), tolerance (±5%), power rating (13W), wirewound composition, moisture resistance, temperature coefficient (±30ppm/°C), operating temperature range, package (axial), size/dimension, and number of terminations (2). Compliance attributes, packaging type, and series designation also affect direct substitutability as documented.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW0102K700JS73 and the substitute part CW0102K700JE73 is guided by product status (active), equivalent electrical and mechanical specifications, and compliance criteria. For applications requiring RoHS compliance and unaffected REACH status, CW0102K700JE73 should be considered. The packaging format must correspond to specific assembly process requirements: tape & reel (TR) versus cut tape (CT).

Frequently Asked Questions (FAQ)

Q1: What key parameters must be identical for substituting wirewound axial resistors?
