Cross Reference Guide
Vishay Dale
Carbon Composition Cross Reference
The following cross reference guide is intended to assist in finding Vishay Dale film resistor types that are most similar to a particular Allen-Bradley carbon composition type. Direct interchangeability is not implied due to differences in technology, however, electrical characteristics typically will be met or exceeded.
