Phoenix Contact 1751390 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1751390 is a 2-position wire-to-board terminal block from the COMBICON MKKDS series, designed for horizontal PCB mounting with side entry wire connection. This component is classified as Active and remains in production. Alternative equivalent parts may be required due to inventory constraints, application-specific pitch requirements, or design modifications that accommodate different mounting specifications or current ratings.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 282836-2 is identified as a substitute for the Phoenix Contact 1751390 based on the following substitution criteria:

Compatible Parameters:

• 2-position configuration
• Horizontal with board mating orientation
• Through hole mounting type
• Screw-based rising cage clamp wire termination
• 300 V voltage rating
• 16-30 AWG wire gauge compatibility
• Polyamide (PA) housing material
• ROHS3 compliance
• Active product status

Differing Parameters:

• Pitch: 0.197" (5.00mm) versus 0.138" (4.60mm)
• Current rating: 14.6 A versus 10 A
• Screw thread: M3 versus M2
• Torque specification: 0.68 Nm versus 0.22-0.25 Nm
• Number of levels: 1 versus 2
• Series: Buchanan versus COMBICON MKKDS

Substitution is valid when PCB layout accommodates the larger 5.00mm pitch and when the higher current rating and M3 screw specification are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1751390 and TE Connectivity 282836-2 maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between these components depends on PCB layout constraints and application current requirements. The Phoenix Contact 1751390 is specified for designs with 4.60mm pitch spacing and 10 A maximum current. The TE Connectivity 282836-2 accommodates larger 5.00mm pitch spacing and supports higher 14.6 A current loads. Substitution is valid only when PCB footprint design permits the increased pitch dimension and when the M3 screw specification aligns with assembly tooling and torque requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 282836-2 be used as a direct replacement for the Phoenix Contact 1751390?

A: Substitution is possible only if the PCB layout accommodates the 5.00mm pitch spacing of the TE part versus the 4.60mm pitch of the Phoenix Contact part. Direct PCB footprint compatibility cannot be assumed.

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

A: The primary differences are pitch spacing (4.60mm versus 5.00mm), current rating (10 A versus 14.6 A), screw thread size (M2 versus M3), and torque specification (0.22-0.25 Nm versus 0.68 Nm). Both share identical voltage rating, wire gauge range, mounting type, and termination method.

Q: Are both parts RoHS compliant?

A: Yes, both the Phoenix Contact 1751390 and TE Connectivity 282836-2 are ROHS3 compliant.

Q: What wire gauges are supported by both terminal blocks?

A: Both components accept wire gauges from 16 AWG to 30 AWG.

Q: Does the higher current rating of the TE part affect compatibility?

A: The higher 14.6 A rating of the TE Connectivity 282836-2 does not prevent substitution in applications requiring 10 A or less. However, PCB pitch accommodation remains the primary constraint for substitution feasibility.

Q: What is the significance of the different screw threads (M2 versus M3)?

A: The M2 thread on the Phoenix Contact part requires different assembly tooling and torque application (0.22-0.25 Nm) compared to the M3 thread on the TE part (0.68 Nm). Assembly procedures and torque specifications must be adjusted accordingly during substitution.
