Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1701621 is determined by the following critical parameters:

Mechanical Compatibility:

• Positions per level (3)
• Pitch spacing (0.400" / 10.16mm)
• Front panel connection type (Header, Male Pins)
• Rear panel connection type (PCB Pins - Right Angle)
• Panel mount type (2 Piece, Snap Lock)
• Panel thickness range (0.039" - 0.118")
• Width (1.965" / 49.92mm)
• Color (Green)
• Number of levels (1)

Electrical Compatibility:

• Voltage rating (UL)
• Current rating (UL)
• Series family (COMBICON DFK-PC)

The substitute part Phoenix Contact 1701469 maintains identical mechanical specifications and series designation. Electrical ratings differ; the substitute provides reduced voltage (300 V vs. 600 V) but increased current capacity (66 A vs. 5 A). Selection depends on the specific electrical requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701469 is the direct substitute for the obsolete 1701621. Both components are RoHS compliant and belong to the same COMBICON DFK-PC series with identical mechanical specifications.

Selection Criteria:

The 1701469 is suitable for applications where the electrical requirements fall within its ratings: maximum 300 V and maximum 66 A. If the original design requires the 600 V rating of the 1701621, the 1701469 is not electrically compatible and alternative solutions must be evaluated.

The 1701469 is currently in active production status with confirmed inventory availability, providing supply chain continuity for new designs and production support.

Frequently Asked Questions (FAQ)

Q: Can the 1701469 be used as a direct mechanical replacement for the 1701621?

A: Yes. Both parts share identical mechanical specifications including pitch, position count, panel mount type, width, and panel thickness range. Physical installation and PCB layout compatibility are maintained.

Q: What are the electrical differences between these parts?

A: The 1701621 is rated for 600 V at 5 A. The 1701469 is rated for 300 V at 66 A. Selection depends on whether your circuit operates within the 1701469's voltage and current limits.

Q: Why is the 1701621 listed as obsolete?

A: The 1701621 has been discontinued by Phoenix Contact. The 1701469 serves as the active production equivalent within the COMBICON DFK-PC series.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1701621 and 1701469 meet RoHS compliance requirements.

Q: What packaging is available for the 1701469?

A: The 1701469 is supplied in bulk packaging.
