Phoenix Contact 1897775 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897775 is a 10-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting with press-fit PCB attachment. This component belongs to the COMBICON EMKDS series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing system maintenance, repair, and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897775 is determined by the following critical parameters:

Core Compatibility Parameters:

• 10-position configuration
• 0.200" (5.08mm) pitch spacing
• Horizontal with board mating orientation
• Screw-based wire termination (Rising Cage Clamp)
• Wire gauge acceptance: 14-30 AWG
• Voltage rating: minimum 300 V
• Current rating: minimum 10 A

Allowable Variations:

• Mounting type may differ (press-fit to through-hole conversion requires PCB redesign consideration)
• Screw thread size and torque specifications may vary with mounting type change
• Series designation may differ within Phoenix Contact COMBICON family
• Product status may transition from obsolete to active

The substitute part 1715802 maintains all core compatibility parameters while offering enhanced current capacity and active product status, making it suitable for direct functional replacement in applications where PCB mounting method can be accommodated.

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1715802

The 1715802 is the designated substitute for the obsolete 1897775. Both components maintain identical electrical specifications (300 V, 10-30 AWG wire gauge) and mechanical configuration (10 positions, 5.08mm pitch, horizontal orientation, screw termination). The 1715802 provides enhanced current capacity (15 A versus 10 A) and holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The primary design consideration is the transition from press-fit to through-hole mounting. This substitution requires PCB footprint modification to accommodate through-hole plating and mechanical hole sizing. The M3 screw thread and increased torque specification (0.5-0.6 Nm) reflect the through-hole mounting architecture and do not impact electrical performance.

Both components are RoHS compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 1715802 directly replace the 1897775 without PCB modification?

A: No. The 1897775 uses press-fit mounting while the 1715802 requires through-hole mounting. PCB footprint redesign is necessary to accommodate the different mounting method. The electrical and mechanical interfaces remain compatible once the PCB is modified.

Q: Are the electrical ratings compatible between these parts?

A: Yes. Both components operate at 300 V and accept 14-30 AWG wire. The 1715802 provides higher current capacity (15 A versus 10 A), making it suitable for applications requiring the original 10 A specification.

Q: What is the impact of the different screw threads (M2 versus M3)?

A: The screw thread size change reflects the mounting type transition. M3 threads in the 1715802 provide increased mechanical robustness for through-hole applications. Torque specifications must be observed during installation: 0.22-0.25 Nm for the 1897775 and 0.5-0.6 Nm for the 1715802.

Q: Does the series change from EMKDS to MKDS affect compatibility?

A: No. Both series belong to the Phoenix Contact COMBICON family and share identical electrical and mechanical specifications for this 10-position, 5.08mm pitch configuration. The series designation reflects internal product line organization.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active status ensures continued manufacturing, availability, and regulatory compliance updates. The 1715802 will remain available for procurement and receives current RoHS3 certification, whereas the 1897775 is no longer manufactured.

Q: Are there any MSL or environmental considerations?

A: Both components carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling requirements are identical between the two parts.
