No design modifications are required for direct substitution.

Q: What is the significance of the contact length differences between TE Connectivity and Molex parts?

A: Contact length affects the depth of engagement with mating connectors and the penetration depth into PCB vias. The TE Connectivity 104350-3 and 5-146257-3 feature 0.230" mating contact length and 0.120" post length. Molex C-Grid 70280 standard variants feature 0.240" mating contact length and 0.107" post length. These differences result in overall contact lengths of 0.440" (TE) versus 0.437" (Molex). The 0.003" difference is within typical manufacturing tolerances and does not affect functional compatibility. However, applications with tight dimensional constraints should verify accommodation of these variations.

Q: Are Molex C-Grid 70280 and C-Grid 70287 parts interchangeable?

A: C-Grid 70280 and C-Grid 70287 parts are not fully interchangeable due to post length differences. C-Grid 70280 standard variants feature 0.107" post length, while C-Grid 70287 variants feature 0.125" post length. Additionally, C-Grid 70287 parts include kinked pin termination capability. Selection between these series depends on PCB thickness and assembly process requirements. Verify post length compatibility with your specific PCB design before selection.

Q: What is the difference between standard and extended post variants in the Molex C-Grid 70280 series?

A: Standard C-Grid 70280 variants (0010897060, 0010897061, 0010897062) feature 0.107" post length, resulting in 0.437" overall contact length. Extended post variants (0702800591, 0702800631, 0702800671) feature 0.175" post length, resulting in 0.505" overall contact length. The extended post design accommodates thicker PCBs or applications requiring deeper via penetration. Selection depends on your specific PCB thickness and assembly requirements. Both variants maintain identical mating contact length (0.240") and all other electrical specifications.

Q: How do contact finish options affect connector performance?

A: Contact finish affects corrosion resistance, contact resistance, and solderability. The original 104350-3 features Gold mating contact finish (30.0µin thickness) with Tin-Lead post finish.

However, contact length variations exist. Molex standard variants feature slightly different post lengths (0.107" versus 0.120") and mating contact lengths (0.240" versus 0.230"). These differences are typically within acceptable tolerances but should be verified against your specific PCB design, via depth, and mating connector specifications. Extended post and kinked pin variants require additional verification of post length compatibility.

Q: What is the current rating for Molex C-Grid parts?

A: Current rating is not specified in the provided data for Molex C-Grid 70280 and C-Grid 70287 variants. The original TE Connectivity 104350-3 specifies 3A current rating.
