Key Parameters

Substitute Part Grouping Explanation

Phoenix Contact part number 1701456 qualifies as a direct substitute based on the following critical parameters:

• Identical 2-position configuration with 0.400" (10.16mm) pitch spacing
• Matching mechanical form factor: 1.565" width and panel thickness tolerance of 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Identical connector interface: header with male pins on front panel, PCB pins with right-angle configuration on rear
• Identical panel mounting method: 2-piece snap-lock design
• Same series designation (COMBICON DFK-PC) and color (green)
• Full RoHS compliance maintained

The primary distinction between these parts is product status: 1701618 is obsolete while 1701456 is active, with 1701456 offering superior electrical ratings (300 V / 66 A versus 600 V / 5 A on the original part).

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1701456 is the appropriate substitute for obsolete part 1701618. Both components maintain identical mechanical and electrical interface specifications within the COMBICON DFK-PC series. The substitute part carries active product status with confirmed inventory availability (615 pcs), ensuring reliable procurement for replacement and new applications.

Both parts maintain RoHS compliance and equivalent moisture sensitivity ratings (MSL 1 - Unlimited), supporting deployment in standard industrial environments. The electrical rating differences (voltage and current) reflect design variations within the series and should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can 1701456 be used as a direct replacement for 1701618 in existing designs?

A: Yes. The parts share identical mechanical dimensions, pitch spacing, connector interface type, and panel mounting configuration. Physical interchangeability is confirmed across all mechanical parameters.

Q: What is the significance of the different voltage and current ratings?

A: The electrical ratings reflect design variations within the COMBICON DFK-PC series. Part 1701456 provides higher current capacity (66 A versus 5 A) at reduced voltage (300 V versus 600 V). Application requirements determine which rating is appropriate.

Q: Why is 1701618 listed as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. Part 1701456 remains in active production and is the current equivalent offering within the same series.

Q: Are there packaging differences between these parts?

A: Part 1701618 packaging is unspecified in available documentation. Part 1701456 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), supporting equivalent deployment in regulated applications.
