Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1716357 is determined by strict alignment of the following electrical and mechanical parameters:

• Position count and pitch: Both main and substitute parts must maintain 9 positions at 0.300" (7.62mm) pitch to ensure PCB layout compatibility
• Current rating: UL-rated current capacity of 41 A must be maintained or exceeded
• Color specification: Green color designation must match for visual identification and circuit tracing
• Connector type: Front connection as male pin header and rear connection as PCB-mounted pins
• Panel mounting: Snap lock mechanism with 2-piece assembly
• Panel thickness tolerance: 0.039 ~ 0.118" (1.0 ~ 3.0mm) compatibility
• Compliance: RoHS compliance status must be maintained
• Width: 3.704" (94.08mm) standard width

The Phoenix Contact 1716357 is substitutable with part number 1727650, which shares all critical electrical and mechanical parameters while offering an active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1727650 is the direct substitute for the obsolete 1716357 model. Both components maintain identical electrical ratings (41 A UL current), mechanical dimensions (9 positions, 0.300" pitch, 3.704" width), and compliance certifications (RoHS). The 1727650 offers the advantage of active product status, ensuring continued availability and supply chain support.

The primary mechanical difference is the rear pin configuration: the 1716357 features straight PCB pins, while the 1727650 provides right-angle PCB pins with an added front flange on the snap lock assembly. This difference requires verification of PCB layout compatibility in the target application. If straight rear pins are mandatory for your design, alternative sourcing strategies may be necessary. If right-angle pins are acceptable or preferred, the 1727650 provides a fully compliant, actively manufactured replacement.

Both parts maintain identical panel thickness tolerance (0.039 ~ 0.118") and snap lock mounting mechanism, ensuring mechanical interchangeability in panel-mount applications where the rear pin angle does not create spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1727650 directly replace the 1716357 in all applications?

A: The 1727650 is electrically and mechanically compatible with the 1716357 for all standard terminal block functions. However, the rear pin configuration differs: the 1716357 has straight pins while the 1727650 has right-angle pins. Verify that your PCB layout accommodates right-angle pins before substitution.

Q: What is the significance of the "Front Flange" addition on the 1727650?

A: The front flange on the 1727650's snap lock assembly provides additional mechanical stability during panel mounting. This does not affect electrical performance and is compatible with standard 0.039 ~ 0.118" panel thickness applications.

Q: Are both parts RoHS compliant?

A: Yes, both the 1716357 and 1727650 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the 1716357 listed as obsolete?

A: The 1716357 has been superseded by the 1727650 in Phoenix Contact's product line. The 1727650 offers the same electrical specifications with improved mechanical features and active manufacturing status.

Q: What is the voltage rating difference between the two parts?

A: The 1716357 does not specify a UL voltage rating in available documentation. The 1727650 is rated for 300 V UL. Both parts are suitable for standard industrial terminal block applications within their respective specifications.

Q: Are there packaging differences between these parts?

A: The 1716357 is listed with unspecified packaging, while the 1727650 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
