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.

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.
