| + | ======MetaTek Part Numbers==== | ||
| + | Part numbers in drawings and bill of materials starting with "// | ||
| + | |||
| + | * **[[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, | ||
| + | |||
| + | ===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, | ||
