Equivalent & Substitute Parts Reference: Hammond Manufacturing 850L

Part Overview

The Hammond Manufacturing 850L is an audio transformer designed for chassis mount applications, featuring specific primary and secondary impedance values suitable for broadcast quality signal transfer within the 20Hz ~ 20kHz frequency range. The part status is listed as Obsolete, indicating discontinued production and limited future availability. Because project requirements may necessitate continued production design or ongoing maintenance, it is necessary to identify alternative models with matching electrical and mechanical parameters.

Engineering Selection Recommendations

The Hammond Manufacturing 850LA is currently listed as Active, while the Hammond Manufacturing 850L is Obsolete. Both parts meet ROHS3 compliance and are REACH unaffected, which are necessary for regulatory conformity in most technical applications. The substitute part matches all provided key electrical and mechanical parameters. Termination style differs—Solder Lug (850L) versus Wire Leads (850LA)—and should be considered in system assembly design based only on available documented mounting and connection specifications.
