Phoenix Contact 1897704 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897704 is a 3-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, design updates, and procurement continuity. The primary substitute maintains core electrical and mechanical compatibility while offering enhanced current capacity and active product status.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1715734 qualifies as a functional substitute for the 1897704 based on the following alignment of critical parameters:

• Electrical Compatibility: Both parts maintain 300 V voltage rating and support 14-30 AWG wire gauge, ensuring compatibility with existing circuit designs
• Mechanical Interface: Both feature 3 positions at 0.200" (5.08mm) pitch with horizontal board orientation and screw-based rising cage clamp termination
• Housing & Materials: Identical polyamide (PA) nylon construction ensures mechanical fit and environmental performance
• Regulatory Compliance: Both are RoHS compliant, meeting environmental standards

Key Differences Affecting Substitution:

• Mounting Type: 1897704 uses press-fit attachment; 1715734 uses through-hole mounting
• Current Rating: 1897704 rated at 10 A; 1715734 rated at 15 A (higher capacity)
• Product Status: 1897704 is obsolete; 1715734 is active
• Series Designation: 1897704 belongs to EMKDS series; 1715734 belongs to MKDS series

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: The Phoenix Contact 1715734 is suitable as a replacement for the 1897704 in applications where PCB mounting method can be adapted from press-fit to through-hole. The substitute offers improved current capacity (15 A versus 10 A), providing design margin for existing or future load requirements.

Compliance Considerations: The 1715734 meets ROHS3 compliance, representing a more current regulatory standard than the RoHS compliance of the 1897704. Both parts maintain unlimited moisture sensitivity level (MSL 1), ensuring equivalent environmental performance.

Procurement Status: The 1897704 is obsolete with limited remaining inventory (989 pcs). The 1715734 is an active product with higher inventory availability (1430 pcs), supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the 1715734 directly replace the 1897704 without PCB redesign?

A: Electrical and mechanical compatibility is maintained. However, the mounting method differs: 1897704 requires press-fit holes; 1715734 requires through-hole vias. PCB layout modification is necessary.

Q: What is the significance of the current rating difference (10 A vs. 15 A)?

A: The 1715734's higher current rating (15 A) indicates improved conductor and contact design. It can safely handle the 1897704's maximum load (10 A) with additional capacity margin. No derating is required for equivalent current applications.

Q: Are the screw specifications interchangeable?

A: No. The 1897704 uses M2 screws with 0.22-0.25 Nm torque; the 1715734 uses M3 screws with 0.5-0.6 Nm torque. Termination hardware must match the selected part.

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

A: Series designation reflects product line evolution. Both series maintain identical pitch, position count, and electrical ratings. The change reflects manufacturing updates and active product status.

Q: What packaging differences exist?

A: The 1897704 packaging is unspecified; the 1715734 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.

Q: Is the 1715734 suitable for new designs?

A: Yes. The 1715734 is an active product with current compliance certifications (ROHS3, REACH Unaffected). It is the recommended choice for new development and long-term production.
