Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702918 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Positions per level: 4
• Pitch: 0.400" (10.16mm)
• Voltage rating: 600 V UL
• Current rating: 5 A UL
• Front panel connection type: Header, Female Sockets
• Rear panel connection type: PCB Pins - Right Angle
• Series: COMBICON DFK-IPC
• Color: Green
• RoHS compliance status

Allowable Variations:

• Width dimension (physical footprint)
• Panel mount configuration details (snap lock variations)
• Product status (active vs. obsolete)
• Packaging format

The substitute part 1702510 maintains all mandatory electrical and functional parameters while differing in physical width and panel mount flange configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702510 serves as a direct functional equivalent to the 1702918 for applications requiring 4-position terminal block headers within the COMBICON DFK-IPC series. Both components satisfy identical electrical specifications (600 V UL, 5 A UL) and mechanical interface requirements (0.400" pitch, right-angle PCB mounting, female socket headers).

The primary distinction is physical width: the 1702510 measures 2.550" (64.76mm) compared to the 1702918's 3.217" (81.72mm). This dimensional difference must be evaluated against available panel space in the target application. Both components maintain RoHS compliance and operate within the same panel thickness range (0.039 ~ 0.118").

The 1702510 holds active product status, ensuring continued availability and supply chain support, whereas the 1702918 is classified as obsolete. For new designs or system replacements, the 1702510 is the appropriate selection within this series.

Frequently Asked Questions (FAQ)

Q: Can the 1702510 replace the 1702918 in existing installations?

A: Yes, provided panel space accommodates the 2.550" width of the 1702510. Both components share identical electrical ratings, pitch spacing, and PCB mounting configuration. Physical dimensions must be verified against the installation envelope.

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

A: The 1702918 includes a front flange extending the overall width to 3.217", while the 1702510 measures 2.550" without this feature. The width difference reflects panel mount configuration variations. Verify available panel space before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1702918 and 1702510 are RoHS compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the 1702918 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 1702510 remains in active production within the same COMBICON DFK-IPC series and provides equivalent functionality.

Q: What panel thickness range do these components support?

A: Both components accommodate panel thicknesses from 0.039" to 0.118" (1.0 to 3.0mm).

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components are rated for 600 V UL and 5 A UL with matching pitch (0.400"), position count (4), and connection types (female socket headers with right-angle PCB pins).
