Phoenix Contact 1716289 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1716289 is a 2-position terminal block header with male pins in green, designed for PCB mounting with straight rear panel connections. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations. The COMBICON DFK-PCV series provides reliable electrical connectivity in applications requiring snap-lock panel mounting with 0.300" pitch spacing.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1716289 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Positions per level: 2
Pitch spacing: 0.300" (7.62mm)
Front panel connection type: Header, Male Pins
Panel mount mechanism: Snap Lock
Current rating: 41 A minimum
Color: Green
Panel thickness compatibility: 0.039 ~ 0.118" (1.0 ~ 3.0mm)

The Phoenix Contact 1727582 qualifies as a substitute based on matching all critical parameters. While the rear panel connection differs (right angle vs. straight), this represents a mechanical orientation variation compatible with the same electrical interface and mounting footprint.

Engineering Selection Recommendations

The Phoenix Contact 1727582 serves as the primary substitute for the obsolete 1716289 model. Selection between these components should be based on the following criteria:

Product Status Consideration: The 1716289 is obsolete, while the 1727582 maintains active product status with current manufacturing support and availability (1094 units in stock vs. 864 units for the obsolete part).

Compliance Alignment: Both components meet RoHS requirements. The 1727582 carries ROHS3 Compliant certification and REACH Unaffected status, providing enhanced regulatory documentation for new designs and long-term supply chain stability.

Mechanical Interface: The primary difference lies in rear panel connection orientation. The 1716289 features straight PCB pins, while the 1727582 provides right-angle PCB pins with an additional front flange on the snap-lock mechanism. This orientation change requires PCB layout verification to confirm compatibility with existing mounting patterns.

Electrical Equivalence: Both components maintain identical current ratings (41 A), pitch spacing (0.300"), and electrical interface specifications, ensuring functional interchangeability at the connector level.

Frequently Asked Questions (FAQ)

Q: Can the 1727582 directly replace the 1716289 without PCB modification?

A: Electrical compatibility is confirmed. However, the rear panel connection orientation differs (right angle vs. straight). PCB layout verification is required to confirm mechanical fit within the existing mounting footprint.

Q: What is the significance of the front flange addition on the 1727582?

A: The 1727582 includes a front flange as part of its snap-lock mechanism. This provides enhanced panel retention and structural support. Verify that panel thickness and mounting clearances accommodate this design variation.

Q: Are there voltage rating differences between these components?

A: The 1716289 specifies current rating only (41 A). The 1727582 provides both voltage (300 V) and current (41 A) ratings. Both components are suitable for equivalent electrical applications within these specifications.

Q: Why is the 1716289 obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 1727582 represents the active COMBICON DFK-PC series successor, offering improved compliance documentation and ongoing manufacturing support.

Q: What packaging differences exist between these parts?

A: The 1716289 packaging is unspecified in available documentation. The 1727582 is supplied in bulk packaging, suitable for production assembly environments.

Q: Are both components RoHS compliant?

A: Yes. The 1716289 is RoHS Compliant. The 1727582 carries ROHS3 Compliant certification, representing current regulatory standards.
