Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1702879 is determined by the following critical parameters:

• Positions per level: 8
• 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 compatibility: COMBICON DFK-IPC
• Color: Green
• RoHS compliance: Required

The substitute part 1702552 maintains all critical electrical and mechanical parameters required for functional equivalence. Both parts share identical pitch, voltage, current ratings, connection types, and series designation. The primary difference is the panel mount configuration and overall width dimension, which do not affect electrical performance or core functionality.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702552 is the designated substitute for the obsolete 1702879. Both components are manufactured by Phoenix Contact within the COMBICON DFK-IPC series and maintain identical electrical specifications (600 V UL, 5 A UL) and mechanical interface parameters (8 positions, 0.400" pitch, PCB pins right angle).

The 1702552 holds active product status, ensuring ongoing availability and supply chain continuity. Both parts carry RoHS compliance certification, meeting environmental and regulatory requirements.

The width difference (4.817" versus 4.150") and panel mount configuration variation (front flange versus standard snap lock) reflect design refinements in the active product line. These dimensional changes do not affect electrical performance or core terminal block functionality.

Frequently Asked Questions (FAQ)

Q: Can the 1702552 directly replace the 1702879 in existing designs?

A: The 1702552 maintains all critical electrical and mechanical parameters: 8 positions, 0.400" pitch, 600 V UL rating, 5 A UL rating, female socket headers, and right-angle PCB pins. Panel mount configuration and width dimensions differ; physical space constraints must be evaluated for specific applications.

Q: What is the significance of the product status difference?

A: The 1702879 is obsolete, indicating discontinued manufacturing and limited availability. The 1702552 is active, ensuring reliable procurement and ongoing manufacturer support.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1702879 and 1702552 are RoHS compliant, meeting environmental and regulatory standards.

Q: What determines substitution eligibility for COMBICON DFK-IPC terminal blocks?

A: Substitution is based on matching position count, pitch spacing, voltage and current ratings, connection types (front and rear), color designation, and series compatibility. All these parameters are identical between the 1702879 and 1702552.

Q: Does packaging affect substitution compatibility?

A: Packaging format (bulk versus other designations) does not affect electrical or mechanical compatibility. It reflects supply and handling specifications only.
