MX2.0mm Connectors – Compatible with Molex 51005 / 51006 Series
MX2.0mm Wire-to-Board Connectors – Compatible with Molex 51005 / 51006 Series
Yoeruyo's MX2.0mm connector range delivers reliable wire-to-board and wire-to-wire interconnections at the 2.0mm pitch, fully compatible with the Molex 51005 (housing) and 51006 (PCB header) series — a widely adopted connector system in consumer electronics, portable devices, battery packs, LED lighting modules, and compact industrial equipment. The 2.0mm pitch strikes the ideal balance between compact footprint and practical wire gauge capacity, making it one of the most specified connectors in modern electronics design.

Why Choose Yoeruyo MX2.0mm Connectors
- ✅ Molex 51005/51006 compatible – dimensionally and electrically compatible with genuine Molex 51005 housings and 51006 PCB headers
- ✅ Gold-plated contacts – gold over nickel plating ensures low contact resistance and long-term reliability in high-cycle applications
- ✅ Positive latch retention – audible click confirmation prevents accidental disconnection in vibration-prone environments
- ✅ Compact 2.0mm pitch – ideal for space-constrained PCB designs requiring more circuits than 2.54mm allows without stepping down to 1.25mm
- ✅ RoHS & REACH compliant – halogen-free materials meet EU and global environmental standards
Buying Guide – Selecting the Right MX2.0mm Component
- Circuit count – select the number of circuits to match your wiring requirements; available from 2 to 15 positions in single-row configuration
- Wire gauge – MX2.0mm terminals accept AWG 22–28 (0.08–0.33mm²); confirm your wire gauge before ordering terminals
- PCB header orientation – vertical headers for standard wire-to-board connections; right-angle for edge-mount and space-constrained PCB layouts
- Pre-crimped assemblies – for OEM integration, pre-crimped wire assemblies eliminate crimping tool requirements and reduce assembly time and error rate
- Compatibility check – verify the housing and header part numbers match the Molex 51005/51006 series before ordering for drop-in replacement applications
Frequently Asked Questions
Are these connectors compatible with Molex 51005 and 51006?
Yes. Yoeruyo MX2.0mm housings are dimensionally compatible with Molex 51005 series wire-side housings, and our PCB headers are compatible with Molex 51006 series PCB receptacles. They mate correctly with genuine Molex counterparts.
What wire gauge is compatible with MX2.0mm terminals?
MX2.0mm crimp terminals accept wire from AWG 28 to AWG 22 (0.08mm² to 0.33mm²). This covers most signal and low-power wiring applications. For higher current requirements, consider the MX2.54mm or MX4.2mm series.
What is the current rating per contact?
The MX2.0mm terminal is rated at 3A per contact. For multi-circuit connectors carrying power, distribute the load across multiple contacts if the total current exceeds 3A per circuit.
Do you offer pre-crimped wire assemblies?
Yes. Custom wire-to-connector assemblies with pre-crimped MX2.0mm terminals are available in specified wire lengths, gauges, and circuit counts. Contact us for OEM assembly quotations and lead times.
What crimping tool is required?
MX2.0mm terminals require a precision crimp tool compatible with 2.0mm pitch micro terminals (e.g., Molex 63811-8900 or equivalent). A proper ratchet micro-crimp tool is essential for reliable, low-resistance crimps — plier crimping is not suitable for this pitch.
