Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1701731 is determined by strict equivalence across the following critical parameters:

• Series and Connector Type: Both parts must belong to the COMBICON DFK-PC series with identical 6-position header configuration
• Electrical Ratings: Voltage (600V UL) and current capacity must meet or exceed the original specification
• Mechanical Compatibility: Pitch (0.400"), width (3.792"), panel thickness range (0.039 ~ 0.118"), and panel mount type (2 Piece, Snap Lock - Front Flange) must be identical
• Connection Configuration: Front panel male pin header and rear PCB right-angle pin configuration must match
• Color and Features: Green color with threaded mating lock and shield connection front side must be preserved
• Compliance: RoHS compliance and MSL rating must be maintained

The Phoenix Contact 1701579 qualifies as a direct substitute based on full parameter equivalence across all mechanical and electrical specifications, with the distinction that it carries an active product status and higher current rating (66A versus 5A).

Parameter Comparison

Both parts maintain full RoHS compliance and identical moisture sensitivity ratings, supporting equivalent environmental performance in target applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1701579 be used as a direct replacement for the 1701731?

A: Yes. The 1701579 is mechanically and electrically equivalent to the 1701731 across all specified parameters, including pitch, panel mount type, connector configuration, and voltage rating. The parts are interchangeable in applications designed for the original 1701731.

Q: What is the significance of the current rating difference between these parts?

A: The 1701731 is rated for 5A, while the 1701579 is rated for 66A. This difference reflects the current-carrying capability of each part. The 1701579 can handle higher current loads without exceeding thermal or electrical limits. For applications requiring only 5A or less, both parts perform identically. For applications requiring higher current capacity, the 1701579 is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The 1701731 packaging is not specified in the available data. The 1701579 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Why is the 1701731 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The 1701579 represents the active equivalent, ensuring continued availability for new designs and replacement applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1701731 and 1701579 are RoHS compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), supporting equivalent environmental and regulatory performance.
