Product details

What this 20-position header fits

The 5054332091 is a 20-circuit, dual-row, shrouded header from the Micro-Lock PLUS 505433 series. It mates with the corresponding Micro-Lock PLUS receptacle (crimp or IDC) to form a board-to-wire connection. The 1.25mm pitch keeps the PCB footprint compact while still allowing manual routing on two-layer boards.

Board mounting and footprint details

Pick-and-place compatible packaging (Tape & Reel) means the header can be loaded directly into a placement machine for high-volume assembly.

No official second-source or cross-reference is listed, so stick with the Molex part number for BOM consistency.

Frequently asked questions

Where can I buy Molex 5054332091 and how do I get a price?

No stock-holding claim — each request is sourced fresh.

What is the pitch of Molex 5054332091?

0.049" (1.25mm) pitch between contacts. This sets the PCB footprint and the per-contact current ceiling — at the rated current the temperature rise stays within the housing material limit.

What is the mating connector for 5054332091?

Mates with a Micro-Lock PLUS 505433 series receptacle (crimp or IDC type). The latch holder on the header locks with the matching latch on the receptacle for vibration-resistant retention.
