Key Parameters

Substitute Part Grouping Explanation

Substitution for the G3NA-440B-2 AC100-240 is determined by the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output switching type: AC with zero-cross capability
• Input voltage specification: 100 ~ 240VAC
• Load voltage range: 180 V ~ 528 V
• Load current rating: 40 A
• Package form factor: Hockey Puck
• Termination method: Screw Terminal
• Mounting configuration: Chassis Mount

The G3NA-440B-UTU-2 AC100-240 satisfies all these parameters and is identified as a direct substitute within the G3NA series.

Parameter Comparison

Engineering Selection Recommendations

The G3NA-440B-UTU-2 AC100-240 is the designated substitute for the obsolete G3NA-440B-2 AC100-240. Both components maintain identical electrical specifications, mechanical form factor, and termination characteristics. The substitute part carries active product status with current manufacturing support from Omron Automation and Safety. Both components are RoHS compliant and carry equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8536.49.0080). The transition from the obsolete variant to the active substitute presents no functional or compatibility constraints for system integration.

Frequently Asked Questions (FAQ)

Q: Are the G3NA-440B-2 AC100-240 and G3NA-440B-UTU-2 AC100-240 electrically interchangeable?

A: Yes. Both components share identical electrical ratings: 40A load current, 100-240VAC input, 180-528V output range, and zero-cross AC switching capability.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The G3NA-440B-2 AC100-240 is obsolete, while the G3NA-440B-UTU-2 AC100-240 is active. The suffix "-UTU-2" and packaging designation (Bulk vs. standard) reflect manufacturing and distribution variants within the same electrical specification.

Q: Can I use the G3NA-440B-UTU-2 AC100-240 as a direct replacement in existing installations?

A: Yes. The substitute maintains identical mechanical mounting (chassis mount, hockey puck package, screw terminals) and electrical performance, enabling direct replacement without circuit modification.

Q: Are both parts RoHS compliant?

A: Yes. Both the G3NA-440B-2 AC100-240 and G3NA-440B-UTU-2 AC100-240 are RoHS compliant.

Q: What should I consider when sourcing the substitute part?

A: Verify that the G3NA-440B-UTU-2 AC100-240 meets your procurement requirements for packaging format (Bulk availability) and lead time, as the original part is no longer manufactured.
