Product details

40-Position Right-Angle Header in the Milli-Grid 87833 Series

The 0878334020: The 2.00mm pitch and 2.00mm row spacing set the PCB footprint for dense signal routing. The solder tails are tin-plated (74.8 µinch) for reliable through-hole soldering.

Latch Holder Retention for Vibration Resistance

This is a practical feature for automotive, telecom, or general-purpose equipment where the assembly sees movement. The black insulator provides visual contrast for inspection.

Comparing the 40-Position to Lower-Count Siblings

The 40-position variant (0878334020) shares the same 2.00mm pitch, dual-row layout, gold mating finish, and right-angle through-hole mounting as the 24-position (0878332420) and 20-position (0878332021) versions. For most signal-level interconnects, the 15.0 µinch gold on the 40-position is adequate.

Frequently asked questions

What is the pitch of Molex 0878334020?

The mating pitch is 2.00mm (0.079 inches), and the row spacing is also 2.00mm. This is a dual-row header with 40 positions arranged in a 2x20 grid.

What is the mating connector for 0878334020?

This header mates with a Milli-Grid 87833 series receptacle (female connector) that accepts the same 2.00mm pitch and latch holder. The exact mating part number depends on your wire termination or cable assembly requirements.

Is 0878334020 RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest RoHS directive requirements.

Can 0878334020 be used in automotive applications?

Yes, the listed applications include Automotive, General Purpose, and Telecommunications. The latch holder and UL94 V-0 housing make it suitable for vibration-prone environments, though the temperature range is -55°C to 105°C.
