Alternate-KiCad-Library

Alternate KiCad Library is a symbol and footprint library for KiCad EDA Software. Symbol libraries contain various analog integrated circuits, discrete semiconductors, LEDs and passive components. Footprint libraries contain passives, diode, LED, transistor and IC packages. All symbols and footprints are either edited versions of standard KiCad components or have been created from scratch.

Version 4.0 is out now, get it via KiCad's PCM or download directly from this repository.

List of changes:

New symbol libraries:

• Crystal_AKL - symbols for crystal resonators and oscillators with pre-assigned footprints
• LED_AKL - colorful symbols for LEDs with pre-assigned footprints (disable 'override individual item colors' in preferences -> colors)
• Voltage_Regulator_AKL - symbols for linear voltage regulators with pre-assigned footprints based on part numbers.

Some symbols have new Alternate Body Styles. Go to symbol properties and check the "Alternate symbol (deMorgan)" checkbox

• 2-pin resistors, diodes and capacitors have a 45-degree rotated version with pins still on the 50 mil grid
• Dual common anode, common cathode and series diodes have an alternative symbol.
• Analog ICs with resistors in their symbols have a US-style resistor version.

Most NC pins were changed to Free unless explicitly indicated as 'Do not connect" by the manufacturer. In some cases having an ability to route through the NC pads or tie them to a heat-sink plane is useful. Now KiCad will allow connecting tracks to these pins, unless they already have an assigned net (i.e. there is already a track running through it)

New symbols for existing symbol libraries:

• Diode_AKL: 1141 new symbols
• Diode_Current_Limiting_AKL: 16 new symbols

Installation instructions for Plugin and Content Manager:

KiCad 8 automatically adds third-party libraries to library tables, by default it also adds the PCM_ prefix to their names. If you have the default PCM_ prefix in Preferences -> Packages and Updates, simply choose the default 4.0.1 version.

If you want no prefixes, simply leave the Library nickname prefix blank and chose version 4.0 in package manager.

Refer to Installation Instructions for more detailed guide

Manual installation:

Extract the downloaded AKL files into any folder you want.

KiCad uses library tables to keep track of installed libraries. To install libraries manually, go to Manage Footprint Libraries in the preferences tab.

Press the Folder icon below the table and locate the folder with the extracted footprint library files

Multiple folders ending in .Pretty should be visible. Each of these is a separate footprint library. Select all the libraries that you want to install and press Select Folder

Next, go to Manage Symbol Libraries in the preferences tab.

Press the Folder icon below the table and locate the folder with the extracted symbol library files

Multiple files ending in .kicad_sym should be visible. Each of these is a separate symbol library. Select all the libraries that you want to install and press Open.

All the installed libraries should be now accessible.

Version 1.1

• SMD Diode, Capacitor and Inductor footprint libraries have been split into standard and hand soldering variants. Capacitor_SMD_Handsoldering_AKL Capacitor_Tantalum_SMD_Handsoldering_AKL Diode_SMD_Handsoldering_AKL Inductor_SMD_Handsoldering_AKL
• Standard libraries are suitable for machine soldering and have no silkscreen under the parts.
• Hand soldering libraries have silkscreen under the part to improve readability of the PCB and reduce component placement errors.
• Footprints (included in those libraries) with bigger pads that used to be called the ‘HandSoldering’ variants have been renamed to ‘BigPads’ to reduce confusion.
• Footprint names between standard and hand soldering libraries are consistent. You can easily swap the footprint by using ‘change footprint’ option and renaming the library in PCBNew.
• Minor improvements to SMD inductor library.
• Some SMD TVS diode footprints had unnecessary polarity marks.
• Crystal and SMD resistor libraries have no silkscreen under the SMD parts.

Version 1.0

• Modified KiCad Libraries: Capacitor_SMD_AKL Capacitor_Tantalum_AKL Capacitor_THT_AKL Crystal_AKL Diode_SMD_AKL Diode_THT_AKL Inductor_SMD_AKL Inductor_THT_AKL Package_DFN_QFN_AKL Package_DIP_AKL Package_LCC_AKL Package_QFP_AKL Package_SO_AKL Package_SON_AKL Package_TO_SOT_SMD_AKL Package_TO_SOT_THT_AKL Resistor_SMD_AKL Resistor_THT_AKL These libraries inherit KiCad’s pad layout and footprint names so you can easily swap footprints using ‘change footprint’ option and renaming the library in PCBNew. Some new footprints have been added, see the showcase folder for details.
• New footprint library: Jumper_AKL Adds THT jumpers with multiple pin pitch and two wire diameters variants. Helpful during single-sided PCB layout.
