Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1716331 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Positions per level: 7
• Pitch: 0.300" (7.62mm)
• Front panel connection type: Header, Male Pins
• Panel mount type: 2 Piece, Snap Lock configuration
• Color: Green
• Number of levels: 1
• Current rating: 41 A (UL)
• RoHS compliance status

Allowable Variation Parameters:

• Rear panel connection type: PCB pins may be straight or right-angle
• Panel mount sub-type: Snap Lock or Snap Lock with Front Flange
• Series designation: Different COMBICON DFK series variants
• Product status: Active status preferred for ongoing availability

The Phoenix Contact 1716331 has one identified substitute: part number 1727634. This substitute maintains all mandatory electrical and mechanical parameters while offering an active product status and alternative rear panel connection geometry.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1727634 serves as the direct substitute for the obsolete 1716331 model. Both components maintain identical electrical specifications (41 A UL current rating) and mechanical dimensions (7 positions, 0.300" pitch, 3.104" width). The 1727634 offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The primary design difference between these parts is the rear panel connection geometry: the 1716331 features straight PCB pins, while the 1727634 provides right-angle PCB pins with an enhanced front flange mounting configuration. This geometric variation does not affect electrical performance but may influence PCB layout requirements depending on available board space and connector orientation needs.

Both components maintain full RoHS compliance and MSL 1 rating, supporting deployment in standard industrial and commercial applications. The 1727634 additionally specifies a 300 V UL voltage rating, providing documented voltage performance data for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the 1727634 directly replace the 1716331 in existing designs?

A: The 1727634 maintains all critical electrical and mechanical parameters required for functional equivalence. The primary consideration is rear panel connection geometry: the 1716331 uses straight PCB pins while the 1727634 uses right-angle pins. PCB layout compatibility must be verified based on available mounting space and connector orientation in your specific application.

Q: What is the significance of the front flange mounting difference?

A: The 1727634 includes a front flange as part of its 2-piece snap lock configuration, compared to the standard snap lock on the 1716331. This enhancement provides additional mechanical stability during panel mounting but does not affect electrical performance or current-carrying capacity.

Q: Are there voltage rating differences between these parts?

A: The 1727634 specifies a 300 V UL voltage rating. The 1716331 does not include documented voltage specification in the provided data. Both parts maintain the same 41 A current rating and are suitable for standard industrial terminal block applications.

Q: What does the obsolete status of the 1716331 mean for procurement?

A: Obsolete status indicates the 1716331 is no longer in active production. The 1727634 is classified as active, ensuring ongoing manufacturing and supply availability. For new designs or system replacements, the 1727634 is the recommended selection.

Q: Are both parts RoHS compliant?

A: Yes, both the 1716331 and 1727634 are RoHS compliant with MSL 1 (unlimited moisture sensitivity level), supporting deployment in regulated environments requiring environmental compliance documentation.
