Phoenix Contact 1701744 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1701744 is a 7-position terminal block header from the COMBICON DFK-PC series, designed for front panel wire connection via male pins with PCB-mounted right-angle rear connections. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part features threaded mating locks and shield connection capability on the front side, with a standard 0.400" (10.16mm) pitch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1701744 is determined by the following critical parameters:

• Manufacturer & Series: Phoenix Contact COMBICON DFK-PC series maintains mechanical and electrical compatibility within the product line
• Pitch: 0.400" (10.16mm) standard spacing ensures connector alignment and mating compatibility
• Panel Mount Type: 2 Piece, Snap Lock - Front Flange configuration must remain consistent for mechanical fit
• Connection Type: Header, Male Pins (front) and PCB Pins - Right Angle (rear) define the interface requirements
• Voltage & Current Ratings: UL-rated electrical specifications establish safe operating parameters
• Color & Features: Green color with threaded mating lock and shield connection capability

The substitute part 1701582 shares the same series, pitch, panel mount configuration, connection types, voltage rating, color, and features. The primary difference is the position count (6 positions versus 7 positions) and current rating (66 A versus 5 A). This substitution is valid only when the application requires 6 positions instead of 7, and the higher current capacity of the substitute part does not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701582 represents an active product alternative within the COMBICON DFK-PC series. Both parts maintain RoHS compliance and identical mechanical mounting specifications. The 1701582 is suitable for applications requiring 6-position connectivity where the original 7-position configuration is not mandatory. The higher current rating (66 A) of the substitute part provides additional electrical capacity without compromising voltage specifications. Selection of the 1701582 is appropriate for new designs and maintenance applications where position count flexibility exists and active product availability is prioritized over exact position matching.

Frequently Asked Questions (FAQ)

Q: Can the 1701582 (6-position) directly replace the 1701744 (7-position)?

A: Direct replacement is possible only if the application circuit requires 6 positions or fewer. The mechanical mounting, pitch, voltage rating, and connector type are identical. Verify that the reduction from 7 to 6 positions does not affect circuit functionality.

Q: Are the pitch and panel mount specifications identical between these parts?

A: Yes. Both parts use 0.400" (10.16mm) pitch and 2 Piece, Snap Lock - Front Flange panel mount configuration, ensuring mechanical compatibility with existing panel cutouts and PCB layouts.

Q: What is the significance of the current rating difference (5 A vs. 66 A)?

A: The 1701582 substitute part has a higher current-carrying capacity. This does not prevent substitution; it indicates the substitute can safely handle higher current loads. Verify that your application current requirements do not exceed the original 5 A specification if design margins depend on this limitation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1701744 and 1701582 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the 1701744 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1701582, classified as active, represents the current product offering within the COMBICON DFK-PC series and is recommended for new procurement.
