Phoenix Contact 1889848 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1889848 is a 3-position wire-to-board terminal block with vertical mating orientation and 0.200" (5.08mm) pitch spacing. This component is part of the COMBICON EMKDS series and features press-fit mounting with screw wire termination. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where vertical terminal block configurations are required.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1730405 is identified as a substitute for the 1889848. Substitution eligibility is determined by the following critical parameters:

Matching Parameters:

• Manufacturer: Phoenix Contact
• Positions Per Level: 3
• Pitch: 0.200" (5.08mm)
• Screw Thread: M3
• Torque Specification: 0.5-0.6 Nm (4.4-5.3 Lb-In)
• RoHS Compliance: Both parts meet RoHS requirements
• MSL Rating: 1 (Unlimited)

Differing Parameters:

• Mating Orientation: 1730405 is horizontal with board (versus vertical for 1889848)
• Mounting Type: 1730405 uses through-hole (versus press-fit for 1889848)
• Current Rating: 1730405 rated at 10 A (versus 12 A for 1889848)
• Wire Gauge: 1730405 accepts 12-30 AWG (versus 16-26 AWG for 1889848)
• Wire Termination: 1730405 uses screw with rising cage clamp (versus screw only for 1889848)
• Series: 1730405 belongs to COMBICON MKDS series (versus EMKDS for 1889848)

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1730405 is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for applications previously using the obsolete 1889848. Both components share identical pitch spacing, screw thread specifications, and torque requirements, establishing a foundation for functional compatibility.

Selection of the 1730405 as a substitute requires evaluation of board-level design constraints. The horizontal mating orientation and through-hole mounting of the 1730405 differ fundamentally from the vertical orientation and press-fit mounting of the 1889848. These differences necessitate PCB layout modifications and mounting hole pattern changes. The current rating reduction from 12 A to 10 A must be assessed against circuit requirements. The expanded wire gauge acceptance range (12-30 AWG versus 16-26 AWG) of the 1730405 provides additional flexibility for wire selection.

Frequently Asked Questions (FAQ)

Q: Can the 1730405 directly replace the 1889848 without PCB modifications?

A: No. The 1889848 features vertical mating orientation with press-fit mounting, while the 1730405 has horizontal mating orientation with through-hole mounting. PCB layout and mounting hole patterns must be redesigned to accommodate the 1730405.

Q: What is the significance of the current rating difference between these parts?

A: The 1889848 is rated for 12 A continuous current, while the 1730405 is rated for 10 A. Applications requiring current levels between 10 A and 12 A must be evaluated to determine if the lower rating of the 1730405 is acceptable for the intended circuit.

Q: Are both parts RoHS compliant?

A: Yes. The 1889848 meets RoHS compliance standards, and the 1730405 meets ROHS3 compliance standards, which represents a more current regulatory requirement.

Q: What wire gauges are compatible with each terminal block?

A: The 1889848 accepts wire gauges from 16 to 26 AWG. The 1730405 accepts a broader range of 12 to 30 AWG, providing greater flexibility for wire selection in substitute applications.

Q: How do the mounting methods differ between these components?

A: The 1889848 uses press-fit mounting, which requires precision-drilled holes on the PCB. The 1730405 uses through-hole mounting with plated vias, requiring different hole sizing and PCB preparation procedures.

Q: Are the screw specifications identical between both parts?

A: Yes. Both the 1889848 and 1730405 use M3 screw threads with identical torque specifications of 0.5-0.6 Nm (4.4-5.3 Lb-In), ensuring consistent wire termination procedures.
