Phoenix Contact 1897733 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897733 is a 6-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal board mounting using press-fit technology. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations. The COMBICON EMKDS series terminal block provides screw-based wire termination with rising cage clamp technology, supporting wire gauges from 14-30 AWG at 10 A and 300 V operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1897733 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Positions per level: 6
• Pitch: 0.200" (5.08mm)
• Mating orientation: Horizontal with Board
• Wire gauge support: 14-30 AWG
• Wire termination method: Screw - Rising Cage Clamp
• Housing material: Polyamide (PA), Nylon
• Color: Green

Allowable Variation Parameters:

• Mounting type: Press Fit (main part) to Through Hole (substitute)
• Current rating: 10 A (main part) to 15 A (substitute) — higher rating is acceptable
• Voltage rating: 300 V (both parts match)
• Screw thread: M2 (main part) to M3 (substitute) — requires PCB redesign
• Torque specification: 0.22-0.25 Nm (main part) to 0.5-0.6 Nm (substitute) — reflects M3 thread change
• Series: COMBICON EMKDS (main part) to COMBICON MKDS (substitute)
• Product status: Obsolete (main part) to Active (substitute)

The Phoenix Contact 1710726 qualifies as a substitute because it maintains all mandatory compatibility parameters while offering improved current capacity and active product status. The transition from press-fit to through-hole mounting and M2 to M3 screw thread represents a design-level change requiring PCB modification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Minimal Redesign): The Phoenix Contact 1710726 is the qualified substitute for the 1897733. Both components maintain identical electrical specifications (300 V, wire gauge 14-30 AWG, screw-based rising cage clamp termination) and mechanical footprint (6 positions, 5.08mm pitch, horizontal board orientation). The 1710726 offers enhanced current capacity (15 A versus 10 A), which provides design margin for existing applications.

Design Considerations: The transition from press-fit (1897733) to through-hole (1710726) mounting requires PCB modification. The screw thread change from M2 to M3 necessitates updated torque specifications during assembly (0.5-0.6 Nm for the 1710726 versus 0.22-0.25 Nm for the 1897733).

Compliance Status: The 1710726 holds active product status with ROHS3 compliance, compared to the obsolete 1897733 with RoHS compliance. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating. The 1710726 includes REACH Unaffected designation, confirming regulatory alignment for new designs.

Frequently Asked Questions (FAQ)

Q: Can the 1710726 be used as a direct drop-in replacement for the 1897733?

A: No. While both components share identical electrical ratings and wire termination methods, the mounting type differs (through-hole versus press-fit). PCB redesign is required to accommodate the 1710726's through-hole mounting pads and M3 screw holes.

Q: What are the key differences between these two terminal blocks?

A: The primary differences are mounting technology (press-fit to through-hole), screw thread size (M2 to M3), current capacity (10 A to 15 A), and product status (obsolete to active). Electrical specifications, pitch, position count, and wire gauge support remain identical.

Q: Is the higher current rating of the 1710726 compatible with existing designs?

A: Yes. The 1710726's 15 A rating exceeds the 1897733's 10 A specification, making it suitable for applications designed around the lower rating. No electrical redesign is necessary from a current capacity perspective.

Q: What torque values should be used during assembly?

A: The 1897733 requires 0.22-0.25 Nm (1.9-2.2 Lb-In) for M2 screws. The 1710726 requires 0.5-0.6 Nm (4.4-5.3 Lb-In) for M3 screws. Assembly procedures must be updated accordingly.

Q: Are both components RoHS compliant?

A: Yes. The 1897733 is RoHS Compliant. The 1710726 is ROHS3 Compliant, representing a more current regulatory standard. Both meet environmental compliance requirements.

Q: What is the pitch spacing, and does it remain the same?

A: Both components maintain 0.200" (5.08mm) pitch spacing. PCB layout modifications are required only for mounting hole repositioning (press-fit to through-hole conversion), not for wire connection spacing.
