Frequently Asked Questions
How many circuits does the 45559-0002 support, and what pitch does it use?
The Molex 45559-0002 is a 2-circuit connector housing with a 1.25 mm pitch, making it one of the finer-pitch options in the Micro-Lock Plus series. This small footprint is ideal for wearables, miniature IoT sensors, and handheld devices where board real estate is scarce.
What is the maximum operating temperature for the 45559-0002, and which environments is it suited for?
The 45559-0002 is rated for continuous operation up to 125°C, with a current rating of 1 A per contact. This thermal tolerance makes it suitable for under-hood automotive accessories, LED lighting modules, and industrial sensor wiring exposed to elevated ambient temperatures.
Which mating connector or header works with Molex 45559-0002 to form a complete 1.25 mm pitch assembly?
The 45559-0002 housing mates with Molex Micro-Lock Plus 1.25 mm pitch PCB headers, such as the 53398 series, providing a secure 2-position wire-to-board interface. The system supports 26–30 AWG wire and a mated height of approximately 4.2 mm above the board surface, fitting very compact enclosures.
For a compact battery-management module with limited PCB space, why choose 45559-0002 over a standard 2.54 mm pitch connector?
The 45559-0002 uses 1.25 mm pitch versus the 2.54 mm standard, cutting connector footprint by roughly 50% while maintaining a 1 A per contact current rating. At 125°C thermal tolerance, it handles battery pack environments, making it a superior choice when board area is under 10 mm² per circuit.
