Product details

9-position 4.20mm pitch header with gold contacts

The 640501-4 is a 9-position, 3-row header from TE's MR (Miniature Rectangular) series, on a 4.20mm pitch.

The 4.20mm pitch and 3-row layout match the MR receptacle footprint. Termination is through-hole solder; the contact length on the post side is 0.210" (5.33mm), which fits standard PCB thicknesses in the 1.6mm range.

RoHS status is non-compliant due to the tin-lead post plating — plan for exemption or alternate finish if RoHS compliance is required.

Frequently asked questions

What is the current rating of the 640501-4?

The 640501-4 is rated 6A per circuit at 250VAC. The gold-plated contacts keep contact resistance stable across the rated current range.

Is the 640501-4 compatible with Molex Mini-Fit Jr receptacles?

No — the 640501-4 is a TE MR series header and mates only with the corresponding MR series receptacle. The 4.20mm pitch and keying are specific to the MR family; Mini-Fit Jr uses a different housing geometry and latch position.

Does the 640501-4 have a latch lock feature?

Yes, the header uses a latch lock fastening type.
