Phoenix Contact 1701728 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1701728 is a 5-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 1701728 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the COMBICON DFK-PC series to ensure mechanical and electrical interchangeability
• Pitch Specification: Identical 0.400" (10.16mm) pitch is required for PCB footprint compatibility
• Panel Mount Configuration: Both parts must use the 2 Piece, Snap Lock - Front Flange mounting system
• Connector Type: Front panel male pin headers with right-angle PCB rear connections
• Electrical Ratings: Voltage rating of 600 V UL is maintained across substitute parts
• Color Coding: Green color designation for consistent identification
• RoHS Compliance: All substitute parts must maintain RoHS compliance status

The primary difference between the main part and its substitute is the number of positions per level. The 1701728 provides 5 positions, while substitute part 1701566 provides 6 positions. This difference allows the substitute to accommodate applications requiring additional connection points while maintaining all other mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701566 serves as the active substitute for the obsolete 1701728. Both components maintain identical mechanical mounting characteristics, electrical voltage specifications, and RoHS compliance status. The 1701566 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary distinction is the increased current rating of 1701566 (66 A versus 5 A) and the additional position capacity (6 positions versus 5 positions). These enhancements make the 1701566 suitable for applications requiring higher current handling or additional connection points while maintaining full compatibility with the COMBICON DFK-PC series infrastructure.

For designs currently utilizing the 1701728, transition to the 1701566 requires PCB layout verification to accommodate the additional position width. The identical pitch and mounting system ensure mechanical compatibility, though panel cutout dimensions may require adjustment to accommodate the sixth position.

Frequently Asked Questions (FAQ)

Q: Can the 1701566 be used as a direct replacement for the 1701728?

A: The 1701566 is mechanically and electrically compatible with the 1701728 within the COMBICON DFK-PC series. However, the additional sixth position increases the overall component width. PCB layout and panel cutout dimensions must be verified before implementation.

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

A: The 1701728 is rated for 5 A per UL specifications, while the 1701566 is rated for 66 A. The 1701566's higher current capacity provides greater flexibility for applications with increased power requirements. Applications limited to 5 A operation can safely use the 1701566 without derating concerns.

Q: Are both parts RoHS compliant?

A: Yes, both the 1701728 and 1701566 maintain RoHS compliance status with MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards.

Q: What is the impact of the position count difference?

A: The 1701728 provides 5 connection positions while the 1701566 provides 6 positions at identical 0.400" (10.16mm) pitch. Applications requiring only 5 connections can utilize the 1701566 with one unused position, or designs can be optimized to use the additional sixth position for expanded functionality.

Q: Is the 1701566 available in the same packaging as the 1701728?

A: The 1701566 is supplied in bulk packaging. Both parts maintain identical mechanical specifications and mounting configurations within the COMBICON DFK-PC series.
