Industrial mobile routing for secure wireless IP communication, remote access and cellular-connected automation networks.
Siemens 6GK5874-3AA00-2AA2 is the SCALANCE M874-3 industrial 3G router for wireless IP communication between Ethernet-based automation equipment and mobile networks. Siemens documents HSPA+, VPN, firewall and NAT functions, a two-port 10/100 Mbit/s Ethernet switch, one digital input and one digital output. The unit supports GSM and UMTS services and uses an SMA connection for an external antenna. It is intended for remote access, telemetry and maintenance architectures where cellular connectivity and controlled network segmentation are required. Before replacement, verify the complete article number, approved radio bands, national approvals, antenna, supply, firmware, security configuration and carrier compatibility.

Siemens lists the lifecycle as PM490: Start of final year of support and states that the product has been discontinued since 01.08.2025. The official product page also states that it was deleted without replacement. A migration decision therefore requires an engineering review of radio technology, approvals, interfaces, security settings and network configuration.
It identifies the Siemens SCALANCE M874-3 industrial 3G router with HSPA+, VPN, firewall, NAT and a two-port Ethernet switch.
Yes. Siemens lists PM490: Start of final year of support and states that the product has been discontinued since 01.08.2025.
No. The official product record states that this product was deleted without replacement.
Verify the two 10/100 Mbit/s RJ45 ports, SMA antenna connection, supply terminal and digital input/output requirements.
No direct interchangeability should be assumed. Radio technology, approvals, interfaces, power, firmware and configuration must be reviewed.

Protective materials, handling requirements, carrier options, shipment tracking and customs documents are coordinated for the confirmed destination.
Written warranty terms, return authorization steps and after-sales response provide a defined communication path for procurement and engineering teams.
Check whether the supplier preserves the complete part number, distinguishes commercial claims from manufacturer facts and provides clear inspection, warranty, shipping and return terms.
Request condition evidence, readable label photos, a written quotation, warranty terms, shipping scope and confirmation that the offered order code exactly matches the inquiry.
Review interfaces, supply, connectors, firmware, configuration, approvals and the installed-system context. Similar appearance does not prove compatibility.
Risk signals include shortened model numbers, reused photos without readable labels, unsupported compatibility promises, unclear condition, missing warranty language and pressure to accept an unverified substitute.
