Different stacking cables for Juniper switches

Anyone familiar with Juniper stacking cables?  I got this cable from Amazon for Juniper EX4300 switch (link below). It does say for Juniper and label indicates For JUN.
However, the original one is thicker and wider connectors.  Has more pins on connectors.  They both fit inside ports just fine.  So wondering if they are the same or completely different cables.  Would the one from Amazon work?

You can find compatible SFPs on link below. You can use any 10Gb SFPs, but Twinax (DAC) cables are cheapest ones.
Hardware Compatibility Tool - EX4300 - as you can see on list, that specific Twinax Cable is supported.
There is also different view - QFX-SFP-DAC-1M compatible devices

Thicker than a SFP+ connector might be QSFP+ , it would help if you uploaded a photo of the original cable so we could tell what it is.

There are no original cables. Virtual chassis is using  regular 10/40 Gb SFP ports, it is not like Cisco's solution with stack modules... generally can be used whatever you want (speed needs to match, if I remember correctly)...
Understanding EX4300 Virtual Chassis
All 40-Gigabit QSFP+ optical ports on an EX4300 switch are configured as VCPs by default. All 10-Gigabit uplink module ports on an EX4300 switch can be configured into VCPs.
Exact model of SFPs that are currently present can be checked on device itself (also new set of cables can be ordered if needed).
