Hi Guys,

Hope you call can help me out on this

Recently we our customer has changed the part number ( customer part number) due to changes in price. But our internal part number - no changes. Anyhow we need to make some amendments internally to our system (especially on delivery site). Therefore in order this changes, Is ECN ( Enginnering change notice) necessary or just a memo to related parties will be sufficient.

Thank you. please give your input and ideas .

Re: Is ECN Necessary for part number change

Is there any risk for confusion or mistake if you don't change your part number?

How specific is your drawing? Does it make particular reference to you client's part number?

You need to change your internal spec if necessary to reflect relevant information, so it all goes the level of detail and required information to make sure you deliver a conforming product and that changes are understood by your company staff.

Perhaps your ECN must reflect the reason as 'customer part number change and the change in price" as the reason and have the next revision number for your internal part number.
I would note that the costing group have to get the Bill of materials and revisions to make suitable changes in your final part costing which then relates to your selling price and finally your profits.
An ECN has several uses., technical (inspection and manufacturing), costing, storage requirement, any handling requirement, ordering requirement .. and more.
