Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1716328 is determined by the following critical parameters:

• Position count: 6 positions per level (fixed requirement)
• Pitch spacing: 0.300" (7.62mm) (fixed requirement)
• Current rating: 41 A UL (fixed requirement)
• Width: 2.804" (71.22mm) (fixed requirement)
• Panel thickness tolerance: 0.039 ~ 0.118" (1.0 ~ 3.0mm) (fixed requirement)
• Color: Green (fixed requirement)
• Front panel connection: Header, Male Pins (fixed requirement)
• Panel mount type: 2 Piece, Snap Lock (fixed requirement)

The Phoenix Contact 1727621 qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary difference lies in the rear panel connection configuration (right angle versus straight) and series designation (COMBICON DFK-PC versus COMBICON DFK-PCV), along with enhanced product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1727621 is the qualified substitute for the obsolete 1716328. Selection of the 1727621 is supported by:

• Active product status: The 1727621 maintains active production status, ensuring long-term availability and supply chain continuity.
• Enhanced compliance: ROHS3 compliance exceeds the RoHS compliance of the original part, meeting current regulatory requirements.
• Electrical equivalence: Identical current rating (41 A UL) and electrical specifications ensure functional compatibility in existing circuit designs.
• Mechanical compatibility: Matching pitch (0.300"), position count (6), width (2.804"), and panel thickness tolerance (0.039 ~ 0.118") confirm direct mechanical fit in standard PCB layouts.

The primary design consideration is the rear panel connection type: the 1727621 features right-angle PCB pins compared to the straight pins of the 1716328. This difference requires verification of PCB layout compatibility and mounting space availability in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1727621 directly replace the 1716328 in all applications?

A: The 1727621 matches all critical electrical and mechanical parameters (position count, pitch, current rating, width, and panel thickness tolerance). However, the rear panel connection differs: the 1727621 uses right-angle PCB pins while the 1716328 uses straight pins. PCB layout compatibility must be verified before implementation.

Q: What is the significance of the series designation change from COMBICON DFK-PCV to COMBICON DFK-PC?

A: The series designation reflects the product line evolution within Phoenix Contact's COMBICON terminal block family. The DFK-PC series represents the current active production line, while DFK-PCV is obsolete. Both series maintain identical electrical and mechanical specifications for this 6-position configuration.

Q: Are there compliance differences between the 1716328 and 1727621?

A: The 1716328 carries RoHS compliance certification, while the 1727621 carries ROHS3 compliance certification. ROHS3 represents an updated compliance standard. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Does the front flange addition on the 1727621 affect compatibility?

A: The 1727621 features a front flange as part of its 2-piece snap lock panel mount design. This addition does not affect electrical compatibility but may impact panel cutout dimensions and mounting clearance. Physical verification is required for panel integration.

Q: What inventory considerations apply to these parts?

A: The 1716328 is obsolete with 883 pieces in stock. The 1727621 is active production with 1005 pieces in stock, providing superior long-term availability and supply chain reliability for new designs and ongoing maintenance requirements.
