Phoenix Contact 1716409 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1716409 is a 3-position terminal block header with male pins in green, designed for front panel wire connection to PCB pins in straight configuration. This component is part of the COMBICON DFK-PCV series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing system maintenance, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1716409 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Voltage rating (300 V UL) and current rating (41 A UL) must match exactly
• Physical Configuration: 3 positions per level, 0.300" (7.62mm) pitch, and 2.263" (57.48mm) width must be identical
• Mechanical Interface: Panel mount type (2 Piece, Snap Lock - Front Flange) and panel thickness tolerance (0.039 ~ 0.118") must be compatible
• Functional Features: Threaded mating lock and shield connection on front side must be present
• Color Specification: Green color designation must be maintained

The primary distinction between the main part and its substitute relates to the rear panel wire connection configuration (straight versus right-angle PCB pins) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1727702 serves as the active equivalent to the obsolete 1716409. Both components maintain identical electrical ratings (300 V, 41 A), mechanical mounting specifications, and functional features. The 1727702 is classified as active and carries ROHS3 compliance, providing assurance of continued availability and regulatory alignment.

The primary design consideration is the rear panel wire connection orientation: the 1716409 features straight PCB pins, while the 1727702 uses right-angle PCB pins. This difference affects PCB layout and mounting geometry. Selection between these configurations depends on the specific PCB design requirements and available board space.

For new designs or system updates, the 1727702 is the appropriate selection due to its active product status and enhanced compliance certification. For legacy system maintenance where the original straight-pin configuration is required, the 1716409 remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the 1727702 directly replace the 1716409 in existing assemblies?

A: Both components share identical electrical ratings, pitch, position count, and mounting type. The primary difference is the PCB pin orientation (right-angle versus straight). Direct replacement is possible only if the PCB layout accommodates right-angle pins. If the original design requires straight pins, physical modification of the PCB may be necessary.

Q: Why is the 1716409 classified as obsolete?

A: The 1716409 belongs to the COMBICON DFK-PCV series, which has been superseded by the active DFK-PC series. The 1727702 represents the current production equivalent within the updated product line.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS compliant. The 1727702 carries ROHS3 certification, representing the current regulatory standard. The 1716409 meets RoHS requirements. Both have MSL rating of 1 (Unlimited) and are ECCN EAR99 classified.

Q: What is the impact of the right-angle versus straight pin configuration?

A: This affects only the PCB mounting geometry. Right-angle pins (1727702) are suitable for edge-mounted or perpendicular board configurations, while straight pins (1716409) are used for direct vertical insertion. Electrical and mechanical performance remain equivalent.

Q: Is the 1727702 available in the same packaging as the 1716409?

A: The 1716409 is packaged as individual units, while the 1727702 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
