Phoenix Contact 1897759 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897759 is an 8-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting with press-fit PCB connection. 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 1897759 has one identified substitute: part number 1715789. Substitution eligibility is determined by the following critical parameters that must remain constant or compatible:

• Positions and Pitch: Both parts maintain 8 positions at 0.200" (5.08mm) pitch, ensuring PCB layout compatibility
• Mating Orientation: Both are horizontal with board configuration
• Voltage Rating: Both rated at 300 V
• Wire Gauge Acceptance: Both accept 14-30 AWG conductors
• Wire Termination Method: Both use screw-type rising cage clamp termination
• Housing Material: Both use polyamide (PA) nylon construction
• Environmental Classification: Both have MSL 1 rating

The primary difference between these parts is the mounting method: the 1897759 uses press-fit PCB mounting, while the 1715789 uses through-hole mounting. This distinction affects PCB design but does not prevent functional substitution in applications where the PCB layout can accommodate through-hole termination.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1715789 is the active substitute for the obsolete 1897759. Selection between these parts depends on PCB design constraints:

Use 1715789 when:

• PCB design can accommodate through-hole mounting
• Higher current capacity (15 A vs. 10 A) provides design margin
• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance is required for new designs

Use 1897759 when:

• Existing PCB layouts are fixed with press-fit mounting holes
• Current application operates within 10 A maximum rating
• Remaining inventory stock is available and acceptable for legacy system maintenance

Both parts maintain identical electrical ratings (300 V), wire gauge acceptance (14-30 AWG), and environmental classification (MSL 1). The screw thread size difference (M2 vs. M3) and corresponding torque specifications reflect the enhanced current-carrying capability of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the 1715789 directly replace the 1897759 in existing designs?

A: Functional replacement is possible if the PCB layout can be modified to accept through-hole mounting instead of press-fit. The electrical and mechanical interfaces are compatible. PCB redesign is required.

Q: What is the current capacity difference, and does it affect compatibility?

A: The 1897759 is rated at 10 A, while the 1715789 is rated at 15 A. The substitute has higher capacity, making it suitable for applications currently using the 1897759. No derating is necessary.

Q: Are the wire termination methods identical?

A: Both parts use screw-type rising cage clamp termination. However, the M2 screw (1897759) and M3 screw (1715789) require different torque specifications: 0.22-0.25 Nm and 0.5-0.6 Nm respectively. Assembly procedures must reflect these differences.

Q: What does the obsolete status of the 1897759 mean for procurement?

A: Obsolete status indicates the part is no longer manufactured. Existing inventory may be available from distributors, but long-term supply cannot be guaranteed. The 1715789 is active and recommended for new designs and future procurement.

Q: Are both parts RoHS compliant?

A: Yes. The 1897759 is RoHS Compliant, and the 1715789 is ROHS3 Compliant. Both meet environmental regulatory requirements for their respective product generations.

Q: Can I use the 1897759 in applications requiring 15 A capacity?

A: No. The 1897759 is rated at 10 A maximum. Applications requiring 15 A capacity must use the 1715789 or a higher-rated alternative.

Q: What is the pitch, and why is it important for substitution?

A: Both parts have 0.200" (5.08mm) pitch, which defines the spacing between terminal positions. Identical pitch ensures PCB footprint compatibility and interchangeability of connector mating interfaces.
