Considerations
Due to the obsolescence of carbon composition resistors by most manufacturers in the late 1990s, existing inventory may be several decades old. As a result, lead lengths are not guaranteed, and there may be some oxidation on the tinned copper leads. It is advisable to clean the leads with a Scotch-Brite pad to ensure proper solderability.
For those seeking alternatives, Vishay Dale offers film resistor types that are similar to Allen-Bradley’s carbon composition models. While direct interchangeability is not implied due to differences in technology, electrical characteristics typically will be met or exceeded.
When selecting a resistor for your application, consider factors such as power dissipation, voltage rating, and environmental conditions to ensure optimal performance and reliability.
