MetaTek Part Numbers

Part numbers in drawings and bill of materials starting with “MT” are MetaTek part numbers. The Bill of Materials links the MT part number to a manufacturer and model for a particular item.

MetaTek Parts

In some cases, manufacturers have discontinued parts or updated them with new part numbers. When this is the case, a revision suffix letter (A-Z) is added to the part number. Parts with identical numbers except for the suffix letter should be functionally identical. Unless noted, newer parts (newer revision letter) should be drop-in replacements, and where a choice of OEM¹⁾ parts does exist, the newer part should be preferred. However, in every such case, care should be taken to verify that the replacement will work satisfactorily.

Examples

MTK102

MT – MetaTek Part number prefix
K – Function: Relay (see following table for complete function listing)
102 – Part identifier

MTK102A

MT – MetaTek Part number prefix
K – Function: Relay
102 – Part identifier
A – Originally specified part. Letter suffix will only be added when there has been a substitution, in which case there should also be an MTK102B listed.
