Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1702853 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Voltage rating (600V UL) and current capacity (5A) must match exactly
• Mechanical Configuration: 6 positions per level with 0.400" (10.16mm) pitch spacing
• Connection Type: Female socket header on front panel with right-angle PCB pins on rear
• Panel Mounting: Snap lock mechanism with compatible panel thickness range (0.039" - 0.118")
• Environmental Compliance: RoHS compliance and MSL rating of 1
• Series Compatibility: COMBICON DFK-IPC series designation

The Phoenix Contact 1702536 meets all these criteria as a direct substitute, with the primary distinction being physical width and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702536 is the designated substitute for the obsolete 1702853 model. Both components maintain identical electrical specifications (600V, 5A), mechanical pitch (0.400"), position count (6), and connection configuration. The 1702536 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary design consideration is the width differential: the 1702536 measures 3.350" (85.08mm) compared to the 1702853 at 4.017" (102.03mm). Panel layout and mounting space must accommodate this 0.667" (16.95mm) reduction in width. Both components share identical panel thickness compatibility and mounting mechanism specifications.

Both parts maintain full RoHS compliance and MSL rating of 1, meeting environmental and reliability standards for industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1702536 be used as a direct replacement for the 1702853 in existing designs?

A: Electrical and functional compatibility is complete. The primary consideration is physical width: the 1702536 is 0.667" (16.95mm) narrower. Panel cutout dimensions and mounting space must be evaluated for your specific application.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components operate at 600V UL voltage rating with 5A current capacity and maintain the same 0.400" (10.16mm) pitch spacing for 6 positions.

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

A: The 1702853 is classified as obsolete, while the 1702536 is in active production. For new designs and long-term supply requirements, the 1702536 is the appropriate selection.

Q: Are there differences in panel mounting between these parts?

A: Both use 2-piece snap lock mounting mechanisms compatible with panel thickness of 0.039" - 0.118" (1.0 - 3.0mm). The 1702853 includes a front flange specification, while the 1702536 does not specify this feature.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level), meeting equivalent environmental and reliability requirements.
