Electronic component search and inventory
MyElecParts is freeware, easy-to-use electronic part finder and inventory software for hobbyists and makers.
Find out what parts you own and where you store them.
You can organize your parts in freely definable part categories. The most common categories are also available by default.
MyElecParts offers hierarchical storage space management. You can keep track of where your parts are physically located.
Please note that the target audience is electronics hobbyists and makers. MyElecParts should not be used for professional or commercial purposes.
Each part category can be assigned characteristic parameters.
It helps to add usual parameters for a part, but it also helps a lot to sort, filter or find a part with choosen parameters.
Parameters can be filled in by typing or dragging from the datasheet, but you can also get them from the results of a meta search (see below),
which makes it very simple and straightforward to enter a new part.
MyElecParts has a full-featured built-in PDF viewer that can display attached documents quickly and easily.
In addition to the basic controls, the viewer also supports thumbnail view, table of contents, text search, text selection with copy and print.
When you view the details of a part, its datasheet automatically opens, giving you instant access to all its features.
MyElecParts comes with a huge set of packages and manufacturers pre-configured.
Each package data contains package image, basic parameters and also package drawing with physical dimensions.
The supplied set covers most of basic parts, and it can be easily extended.
The list of manufacturers includes the main active and discontinued semiconductor and passive component manufacturers.
Inventorying parts is a long and tedious process unless you have a great tool to make it easier.
MyElecParts makes this process simple and quick. You can search for any part and get the results from online sources with basic information such as manufacturer,
packaging, description and even available data sheets. But that's not all, the search also returns typical parameters for discrete semiconductors
and for some integrated semiconductor products as well.
After selecting the right match, it is only a step to create an inventory part, which is pre-populated with the collected parameters and the selected data sheets.
Due to the small size of most SMD components, manufacturers are not able to write the full part number on the package.
They use instead a marking code typically composed of a combination of 2 or 3 letters or digits.
MyElecParts is able to locate the original part number using various online sources.
The list of results may not be accurate as many different parts may have the same marking code,
but filtering by pin number or package can narrow down the results to find a possible match.
MyElecParts requires Windows 7 SP1 or later to run.
The portable version can be extracted into any directory, where the program has write access. Do not use Program Files, there is no write access right there.
MyElecParts requires the .NET Framwork 4.8 Runtime. It is delivered with the Windows 10 operating system. If you're using Windows 10 or later, there is nothing to do. If you are using an older version of the Windows, and do not already have it, please download and install it manually from the Microsoft site:
Download .NET Framework 4.8
MyElecParts also requires a database. By default it uses MSSQL LocalDB and store the database content in files under Data/Database directory.
At first start the program will check if LocalDB is installed and suggests downloading and installing it if it is not yet available.
Instead of LocalDB you might use PostgreSQL or MSSQL Server version. Check the Linux installation part for details.
Run MyElecParts under Wine
Linux is not natively supported, but MyElecParts can be run under Wine.
This is fully experimental, use it at your own risk.
1. The last stable version of Wine needs to be installed. For details visit the
Wine HQ.
2. MSSQL LocalDB is not available for Linux, so PostgreSQL or MSSQL Server Express is needed as database. For search functions only MyElecParts can be used also without database.
MSSQL LocalDB on Windows has the advantage that is store the database content into files under directory Data/Database, and so the backup is very easy.
Just the Data directory needs to be copied for a full backup. If you are using a different database management system, you must back up both the database contents
and the contents of the Data directory to perform a full backup.
Instructions for each database manager can be found here:
Setup PostgreSQL
Setup MSSQL Server Express
3. Unzip MyElecParts to any location. Before the first launch, you must edit the MyElecParts.exe.config file
and configure the parameters for the database you wish to use with the following settings:
In case of PostgreSQL:
<add key="DatabaseType" value="Postgres" />
<add key="DatabaseHost" value="localhost" />
<add key="DatabasePort" value="5432" />
<add key="DatabaseUser" value="postgres" />
<add key="DatabasePass" value="your_postgres_password" />
In case of MSSQL SqlServer Express:
<add key="DatabaseType" value="SqlServer" />
<add key="DatabaseHost" value="localhost" />
<add key="DatabasePort" value="" />
<add key="DatabaseUser" value="sa" />
<add key="DatabasePass" value="your_sa_password" />
Without database:
<add key="DatabaseType" value="None" />
<add key="DatabaseHost" value="localhost" />
<add key="DatabasePort" value="" />
<add key="DatabaseUser" value="" />
<add key="DatabasePass" value="" />
4. Start:
wine MyElecParts.exe
At first start the Wine will ask for downloading and using Mono. Select yes. It will work then.
You can install PostgresSQL based on the official guide here:
https://www.postgresql.org/download/
After installation you need to set a password for postgres user. Replace your_postgres_password with your secure password.
First start psql as postgres user and execute the following SQL statement. Finally exit with exit command:
sudo su - postgres psql ALTER USER postgres WITH PASSWORD 'your_postgres_password'; exit
After this step the database is ready to use. The MyElecPartsDb database and the tables will be created automatically by the program. The default schema in PostgreSQL is "public" but for technical reason MyElecParts uses the schema "dba".
You can install MSSQL Server Express based on the official guide here:
https://learn.microsoft.com/en-us/sql/linux/sql-server-linux-overview?view=sql-server-ver18
During the installation you need to choose the Express version and at the end you need to enter the sysadmin (sa) password. Use the choosen password at setting DatabasePass instead of your_sa_password.
