Phoenix Contact 1897717 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897717 is a 4-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 and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897717 is determined by the following critical parameters:

• Position count and pitch: Must maintain 4 positions at 0.200" (5.08mm) spacing to ensure PCB layout compatibility
• Mating orientation: Must support horizontal mounting with board attachment
• Electrical ratings: Minimum 10 A current and 300 V voltage capability
• Wire gauge compatibility: Must accept 14-30 AWG conductors
• Wire termination method: Screw-based rising cage clamp termination required
• Housing material: Polyamide (PA) or equivalent dielectric material
• Compliance: RoHS compliance required for modern procurement standards

The Phoenix Contact 1897717 has one identified substitute: 1715747. While this substitute differs in mounting technology (through-hole versus press-fit) and belongs to the active COMBICON MKDS series, it satisfies the core electrical and functional requirements for applications where PCB attachment method can be adapted.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement in existing designs: The Phoenix Contact 1715747 is the primary substitute for the obsolete 1897717. Both components share identical pitch, position count, voltage rating, and wire gauge specifications. The 1715747 provides superior current capacity (15 A versus 10 A), making it suitable for applications requiring equal or lower current demands.

Key consideration - Mounting method: The primary design difference is the mounting technology. The 1897717 uses press-fit attachment, while the 1715747 requires through-hole PCB mounting. PCB redesign is necessary if the original design relied on press-fit technology. The 1715747's through-hole mounting provides mechanical robustness suitable for high-vibration or high-stress environments.

Compliance advantage: The 1715747 carries ROHS3 compliance and REACH unaffected status, providing superior regulatory alignment for current procurement and future product certifications. The 1897717's RoHS compliance is adequate but represents an older compliance generation.

Availability: The 1715747 is actively manufactured with substantial inventory (5659 pcs), ensuring long-term supply chain stability compared to the obsolete 1897717 (741 pcs remaining stock).

Frequently Asked Questions (FAQ)

Q: Can the 1715747 be used as a direct drop-in replacement for the 1897717?

A: Electrical and functional compatibility is confirmed. However, PCB modification is required due to the mounting method difference. The 1897717 uses press-fit attachment, while the 1715747 requires through-hole drilling and soldering. Pitch and position spacing are identical, simplifying layout adaptation.

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

A: The M3 thread on the 1715747 requires larger screw holes and provides increased clamping force (0.5-0.6 Nm versus 0.22-0.25 Nm). This is a mechanical advantage for applications requiring secure wire retention under vibration or thermal cycling.

Q: Is the higher current rating (15 A) of the 1715747 a concern for 10 A applications?

A: No. The 1715747's 15 A rating exceeds the 1897717's 10 A specification, making it suitable for applications at or below 10 A. Higher current capacity does not degrade performance in lower-current circuits.

Q: Are there packaging differences between these parts?

A: The 1897717 is supplied in standard packaging, while the 1715747 is supplied in bulk packaging. Bulk packaging is standard for active production components and does not affect electrical or mechanical performance.

Q: What compliance certifications should be verified for new designs?

A: The 1715747 meets ROHS3 and REACH requirements, representing current regulatory standards. For applications requiring specific regional compliance (EU, China, or other markets), verify that ROHS3 and REACH unaffected status align with target market requirements.
