Putting tiny connectors together - WM18873-ND & WM3724CT-ND

I purchased the two parts: WM18873-ND and WM3724CT-ND

I cannot get them to fit together here. I suspect I am missing a special tool for this.

Is there a tool?

If not, can I purchase the parts already made up and wired to a pigtail so I can use them?

Thanks for any help with this.

Hello cbcX, welcome to the DigiKey TechForum,

The WM18873-ND and the WM3724CT-ND are from 2 different series from Molex and don’t appear to be compatible. The WM18873-ND is from the Mini-SPOX 5264 series and the WM3724CT-ND is from the SPOX 5103.

The associated contacts for the WM18873-ND are at the bottom of product page under “associated product” but I have linked them below:

0008701039

0008701040

0039000160

Unfortunately I was unable to find any that are terminated with pigtails. The associated tooling (insertion, extraction, crimp tools) for the contacts can be found at the bottom of the product page under “tooling”.

Thank you so much for your quick response. It is very refreshing to get such a response from a company. (I have been waiting three weeks for a response from another company.)

Thank you for your support!!!
