SIM7600G-H-PCIE variants for mPCIE setup

Hi,

I am currently trying to source some units from DigiKey to replace SIM7600G-H mPCIE modules that I am using in my research.

As such, I found multiple models and wanted to know which one would fit the most to the original model I am using.

The model I am using is a SIMCom SIM7600G-H R2 LTE Cat-4 mPCIe (SIMCOM reference : S2-109KM-Z31E3); it is not available at the time, and does have a mPCIE port but no SIM slot.

I see the following references on the marketplace :

  • SIM7600G-PCIE R2
  • SIM7600G-H-PCIESIM

that both are available at the time.

Which one would be a “drop-in” replacement, in a way that doesn’t need to change anything software wise please?

I see that the SIM7600G-PCIE R2 would not include a SIM slot (which is okay since I use an adapter with a SIM slot to power the module anyway).

The SIM7600G-H-PCIESIM in the other hand, would have closer “network capabilities” to the one I currently use, but would feature an onboard SIM slot, as I understand; would this slot be an hassle when using a separate adapter? I would only use the slot on the module (or the one on the adapter, depending on what it requires).

Thanks for your help,

Anthony

Hello,
Welcome to the DigiKey TechForum. Please verify the DigiKey part number of the exact module you are using so we can make a comparison. Are you currently using DigiKey part 3781-SIM7600G-HR2-ND and looking for a replacement to this ?

Hello Steve,

Yes, I am using this reference, but in a mPCIE package;
The exact module would be labeled SIM7600G-H (R2) PCIE (or SIM7600G-H-PCIE in SIMCOM documentation). You do not seem to have it in stock and I used other suppliers to stock this part previously.

To update this topic, the SIM7600G-H-PCIESIM and SIM7600G-H-PCIESIM (R2) would be “drop-in” replacements to the SIM7600G-H R2 LTE Cat-4 mPCIe

As the hardware note from SIMCOM explains, when added, the on-module SIM port works concurrently to the SIM pin on the mPCIE port; as such, if you plug a SIM on an adapter that uses the mPCIE, the module would work without the need to have SIM plugged into the on-board SIM slot.

I ordered some units and tested this behavior today.

Thanks!
