Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702866 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 7
• Pitch: 0.400" (10.16mm)
• Voltage - UL: 600 V
• Current - UL: 5 A
• Front Panel Wire Connection: Header, Female Sockets
• Rear Panel Wire Connection: PCB Pins - Right Angle
• Panel Thickness Range: 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Color: Green
• Series: COMBICON DFK-IPC

Allowable Variation Parameters:

• Width: Physical dimension variation permitted within mechanical envelope constraints
• Panel Mount Type: Functional equivalence acceptable (Snap Lock variants)
• Features: Optional features do not disqualify substitution

The substitute part 1702549 maintains all mandatory electrical and mechanical parameters while offering active product status and alternative physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702549 serves as a direct functional substitute for the obsolete 1702866 terminal block header. Both components maintain identical electrical ratings (600 V UL, 5 A UL), mechanical pitch (0.400"), position count (7), and connector interface specifications. The primary distinction is physical width, with the 1702549 measuring 3.750" (95.24mm) compared to the 1702866 at 4.417" (112.20mm).

Selection of the 1702549 is supported by its active product status, ensuring continued availability and supply chain reliability. Both components carry RoHS compliance certification and equivalent moisture sensitivity ratings. The substitution is valid for applications where the reduced width dimension accommodates the mechanical envelope requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1702549 directly replace the 1702866 in existing installations?

A: The 1702549 provides electrical and functional equivalence. Substitution validity depends on mechanical space constraints. The 1702549 width of 3.750" (95.24mm) versus the 1702866 width of 4.417" (112.20mm) must be verified against panel cutout and mounting specifications.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components specify 600 V UL voltage rating and 5 A UL current rating with identical pitch (0.400") and position count (7).

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

A: The 1702866 is classified as obsolete, indicating discontinued manufacturing. The 1702549 maintains active status, ensuring ongoing availability and supply chain support for new procurements and system maintenance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1702866 and 1702549 are RoHS compliant with MSL rating of 1 (Unlimited).

Q: Are there differences in panel mount configuration?

A: Both use 2-piece snap lock mounting. The 1702866 includes a front flange feature, while the 1702549 uses standard snap lock configuration. This distinction does not affect electrical substitution eligibility.
