Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 104656-3 and Samtec TFC-115-12-L-D-A-K-TR are Active product status connectors with full RoHS compliance certifications. The TE Connectivity part carries RoHS Compliant status, while the Samtec substitute carries ROHS3 Compliant status, both meeting current regulatory requirements.

The Samtec TFC-115-12-L-D-A-K-TR provides enhanced electrical performance characteristics with a current rating of 3.1A per contact compared to 0.5A per contact on the TE Connectivity part, and includes a specified voltage rating of 275VAC. The Samtec part also supports an extended operating temperature range of -55°C ~ 125°C versus -65°C ~ 105°C on the TE Connectivity part.

Both connectors share identical mechanical specifications including pitch, position count, row spacing, shrouding configuration, and fastening methodology, ensuring direct PCB footprint compatibility. The primary difference in contact geometry (circular versus square) does not affect electrical or mechanical interchangeability in standard board-to-board applications.

Selection between these parts should be based on application-specific current and voltage requirements. The Samtec part is suitable for applications requiring higher current capacity or explicit voltage rating specifications. The TE Connectivity part remains appropriate for standard-current applications within its specified operating parameters.
