Common Terminology
The following terms are used to identify Mark controls components:
Backward Compatible
A part is backward compatible when it can directly replace an earlier version of the part in all
specified end-use applications without requiring any changes to the host system.
Base Part Number
The part number that is used to uniquely identify a part as a component in a higher-level assembly or
to order a backward compatible replacement part. The base part number remains unchanged for all backward-compatible
versions of the part. An example of a base part number is IS220PDIAH1B.
Hardware Form
The three characters following the module or board type in the part number that together with the Type
uniquely defines a module or board in the ToolboxST
*
configuration tool. An example hardware form is H1B.
Module or Board Type
The four letter mnemonic taken from characters 6 – 9 of the full part number that is used to
identify the function of the part. An example of a board type is Pack Discrete Input A (PDIA).
Part Number
The Part Number is the ANSI/EIA-649-A National Consensus Standard for Configuration Management,
Product Identifier, that represents a specific version of a printed wiring assembly (PWA) and consists of all applicable fields
specified in the table
Product Identifier Fields Example
. The Part Number identifies the baseline design of a product and is
changed each time the design is changed. An example part number is IS220PDIAH1BA.
Printed Circuit Board Assembly (PCBA)
Indicates a single board.
Printed Wiring Assembly (PWA)
The ANSI/EIA-649-A National Consensus Standard for Configuration Management,
Product Identifier, that indicates one or more PCBAs.
Printed Wiring Board (PWB)
The PC-T-50 Terms and Definitions for Interconnecting and Packaging Electronic
Circuits that indicates a circuit board without any parts added.
Serial Number/Barcode
A unique number assigned to a component that indicates the date of manufacture and the supply
vendor.
