Distributor part numbers are quoted for contingency and comparison and do not constitute a recommendation or requirement: Purchase of an identical, same manufacturer part from a more cost effective distributor is encouraged. Substitution of parts from a different manufacturer requires engineering approval. In addition, substitution of a different part from the same manufacturer requires engineering approval.
Part numbers may be subject to change.
Distributors part numbers are sometimes for economical buy quantities such as 1000pcs.
It is the readers responsibility to check pack buy quantities, and minimum order
quantities.
Mounting types:
[sm] Part is surface mount
[th] Part is thru-hole
[TP] Part is a test point
[NS] Part is not soldered
Part numbers were originally entered by hand. Verify parts before ordering.
