Key Features
- 13-circuit vertical PicoBlade header at 1.25 mm pitch delivering high-density wire-to-board connectivity in a 21.4 mm body length
- Fitting nail board retention feature ensures secure mechanical anchorage to the PCB, preventing connector tilt during mating and field vibration
- Tin-plated termination contacts compatible with standard reflow solder processes, supporting RoHS-compliant lead-free assembly in consumer and industrial applications
Applications
The 53398-1371 PicoBlade header is used in compact wire-to-board interconnect applications in portable consumer electronics, wearable devices, and small form factor embedded systems where the 1.25 mm pitch saves board space compared to 2.0 mm or 2.54 mm alternatives. Its 13-circuit configuration supports mixed signal and power wiring harnesses in battery management, LED lighting, and sensor interface assemblies. The vertical orientation and fitting nail retention make it well suited for automated PCB assembly followed by connector plug insertion during final device assembly.

Frequently Asked Questions
What pitch and circuit count does the Molex 53398-1371 provide, and how does this compare to standard 2.54 mm pitch headers in space-constrained designs?
The 53398-1371 uses a 1.25 mm pitch with 13 circuits, making its row length approximately 16 mm versus around 32 mm for an equivalent 13-pin 2.54 mm header. This 50% reduction in connector length is critical in wearable devices and compact IoT modules where PCB area is limited and routing 13 wires through a 2.54 mm header would consume more than double the board edge space.
What does the fitting nail on the 53398-1371 do and why is it important for wave-soldered or hand-assembled boards?
The fitting nail is a metal stake that presses into a PCB hole and mechanically locks the 53398-1371 header to the board before soldering. This prevents the connector from tilting or shifting during reflow, which is especially important on a 13-position 1.25 mm pitch connector where even 0.2 mm misalignment can cause bridging between adjacent pads spaced only 1.25 mm apart. It also provides additional pull-out resistance for wire harnesses subject to repeated mating cycles.
What is the body length of the Molex 53398-1371 and what mating wire housing is used with it?
The 53398-1371 has a body length of approximately 21.4 mm (0.843 inch) for its 13-circuit, 1.25 mm pitch row. It mates with Molex PicoBlade wire-to-board plug housings such as the 51021-series crimped to 28 AWG to 32 AWG wires, which are commonly used in battery connector, LED driver, and sensor wiring harnesses in consumer electronics with cable lengths up to 500 mm.
Can the 53398-1371 be used in automotive or industrial applications, and what is its temperature range?
The 53398-1371 PicoBlade header is rated for operating temperatures from -40°C to +105°C, covering most industrial and light automotive interior sensor applications. However, it is not AEC-Q200 qualified as a standard catalog part, so for safety-critical automotive body control or under-hood applications requiring full AEC-Q200 qualification, an automotive-specific PicoBlade variant or a different Molex series should be evaluated instead.
