Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900343 is an active product offering from the same manufacturer with identical coil specifications and switching characteristics. Both components are RoHS compliant and share the same operating temperature range and contact material composition. The 2900343 provides continued availability as the 2912620 is obsolete.

Selection between these components must account for application-specific current and voltage requirements. The 2912620 supports higher contact current (6A) and switching voltage (250VAC/250VDC) compared to the 2900343 (50mA, 30VAC/36VDC). Termination method differs between the two models, requiring mechanical integration assessment. The 2900343 includes socket accommodation, which may affect mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900343 directly replace the 2912620 in all applications?

A: Direct replacement depends on application current and voltage requirements. The 2912620 is rated for 6A at 250VAC/250VDC switching, while the 2900343 is rated for 50mA at 30VAC/36VDC. Substitution is only valid when the application load does not exceed the 2900343 contact rating and switching voltage specifications.

Q: What are the key differences in termination between these models?

A: The 2912620 uses spring terminal connections, while the 2900343 uses screw terminal connections. This difference requires mechanical integration assessment and potential wiring harness modification.

Q: Are both relays compatible with the same DIN rail mounting infrastructure?

A: Both components are specified for DIN rail mounting. However, the 2900343 includes socket accommodation, which may affect physical mounting configuration and spacing requirements.

Q: Do both relays share identical coil specifications?

A: Yes. Both the 2912620 and 2900343 operate at 230VAC/DC coil voltage with 4.5mA coil current and 51.11kOhms coil resistance. Operate and release times are identical at 7ms and 10ms respectively.

Q: What is the significance of the product status difference?

A: The 2912620 is obsolete, indicating end-of-life status with no further manufacturing. The 2900343 is active, ensuring continued availability and supply chain support for new designs and system maintenance.
