Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1733512 is the primary selection for applications requiring RoHS3 compliance. This part maintains active production status and is suitable for standard industrial applications with 15 A current requirements and 55° board angle orientation.

TE Connectivity 1-796690-2 serves as an alternative where higher current capacity (17.5 A) is required or where 35° board angle orientation is specified. However, this part does not meet RoHS3 compliance requirements and is classified as RoHS non-compliant. Selection of this substitute requires explicit confirmation that regulatory compliance with RoHS3 is not mandated for the application.

Both parts share identical pitch spacing, voltage rating, and termination methodology, making them mechanically and electrically compatible at the board interface level when mating orientation and compliance requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796690-2 directly replace the Phoenix Contact 1733512 in existing designs?

A: Direct replacement is possible only if the PCB layout accommodates the 35° mating angle (versus 55°) and if RoHS3 compliance is not a design requirement. The identical 5.00mm pitch and M3 screw thread ensure mechanical compatibility at the termination interface.

Q: What is the significance of the different mating angles?

A: The mating angle determines the physical orientation of the connector relative to the PCB surface. The Phoenix Contact part uses 55° (125° angle with board), while the TE Connectivity part uses 35° (145° angle with board). This affects connector clearance, wire routing, and panel space allocation. Selection depends on the specific mechanical constraints of the application.

Q: Does the higher current rating of the TE Connectivity part make it a superior choice?

A: The 17.5 A rating of the TE Connectivity part exceeds the 15 A specification of the Phoenix Contact part. However, selection should be based on actual circuit requirements rather than over-specification. The higher current rating does not provide functional advantage if the application requires only 15 A.

Q: Are there compliance implications for selecting the TE Connectivity substitute?

A: Yes. The Phoenix Contact 1733512 is RoHS3 compliant, while the TE Connectivity 1-796690-2 is RoHS non-compliant. Applications subject to RoHS3 regulations must use the Phoenix Contact part. Verify regulatory requirements before selecting the TE Connectivity alternative.

Q: What wire gauge ranges are supported by each part?

A: The Phoenix Contact 1733512 accepts 14-30 AWG wire, while the TE Connectivity 1-796690-2 accepts 12-30 AWG wire. The TE Connectivity part supports larger gauge conductors (12 AWG and 13 AWG). Wire gauge selection should match the application's current and voltage requirements.

Q: How do the torque specifications differ between these parts?

A: The Phoenix Contact part specifies 0.5-0.6 Nm torque, while the TE Connectivity part specifies 0.79 Nm. The higher torque value for the TE Connectivity part reflects its higher current rating and potentially different clamp design. Torque specifications must be observed during installation to ensure proper contact pressure and prevent over-tightening.
