Phoenix Contact 1728284 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1728284 is a 2-position wire-to-board terminal block from the COMBICON SMKDS series, designed for through-hole PCB mounting with a 55° angled mating orientation. This component is actively manufactured and stocked, serving applications requiring secure screw-clamp wire termination at 0.150" (3.81mm) pitch spacing. Substitute parts are identified when design requirements permit alternative mating orientations or when inventory constraints necessitate functionally compatible alternatives within the same electrical and mechanical parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1728284 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 2
• Pitch: 0.150" (3.81mm)
• Mounting Type: Through Hole
• Wire Termination: Screw - Rising Cage Clamp
• Screw Thread: M2
• Housing Material: Polyamide (PA), Nylon
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Mating Orientation: Alternative orientations permitted when PCB layout accommodates
• Current Rating: Substitute must meet or exceed 10 A minimum
• Voltage Rating: Must equal or exceed 300 V
• Series: Different COMBICON series acceptable if all mandatory parameters align

The identified substitute part 1727010 maintains all mandatory parameters while offering a horizontal mating orientation alternative and increased current capacity (14.6 A versus 10 A).

Parameter Comparison

Engineering Selection Recommendations

Both the 1728284 and 1727010 maintain active product status and full compliance with ROHS3 and REACH regulatory requirements. Selection between these parts is determined by PCB layout constraints and mating orientation requirements.

The 1728284 is specified for applications requiring a 55° angled connector orientation. The 1727010 provides a horizontal mating orientation alternative with equivalent electrical performance and superior current capacity (14.6 A). Both components utilize identical screw-clamp termination, M2 threading, and torque specifications, ensuring consistent assembly procedures.

Component selection should be based on physical PCB layout accommodation of the required mating orientation and available inventory status.

Frequently Asked Questions (FAQ)

Q: Can the 1727010 be used in place of the 1728284?

A: Substitution is possible only if the PCB layout accommodates the horizontal mating orientation of the 1727010 in place of the 55° angled orientation of the 1728284. All electrical parameters, wire termination methods, and screw specifications are compatible.

Q: What is the primary difference between these two parts?

A: The primary difference is mating orientation. The 1728284 features a 55° angle with the board, while the 1727010 mounts horizontally. The 1727010 also provides higher current capacity (14.6 A versus 10 A).

Q: Are the screw torque specifications identical?

A: Yes. Both parts require 0.22-0.25 Nm (1.9-2.2 Lb-In) torque specification with M2 screw threading.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the 1728284 and 1727010 accept 16-30 AWG wire gauges.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and maintain MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the pitch specification for both parts?

A: Both parts maintain 0.150" (3.81mm) pitch spacing between positions.
