Phoenix Contact 1705689 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1705689 is a 5-position wire-to-board terminal block with 0.150" (3.81mm) pitch, designed for horizontal board mounting using press-fit technology. This component belongs to the COMBICON EMKDS series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1705689 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (10 A), voltage rating (300 V), and wire gauge acceptance (14-30 AWG) must match exactly
• Mechanical Compatibility: Pitch (0.150" / 3.81mm), number of positions (5), and mating orientation (horizontal with board) must be identical
• Termination Method: Wire termination type (screw - rising cage clamp) and screw specifications (M2 thread, 0.22-0.25 Nm torque) must be consistent
• Material and Compliance: Housing material (polyamide/nylon), RoHS compliance, and MSL rating must be equivalent

The Phoenix Contact 1705579 meets all substitution criteria as an active alternative, with the primary difference being the mounting technology (through-hole versus press-fit).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1705579 is the designated substitute for the obsolete 1705689. Both components maintain identical electrical and functional specifications, ensuring direct compatibility in applications requiring 5-position, 3.81mm pitch terminal blocks with 10 A / 300 V ratings.

The primary design consideration is the mounting technology difference: the 1705689 uses press-fit mounting, while the 1705579 employs through-hole mounting. This distinction requires PCB layout modification but does not affect electrical performance or wire termination characteristics.

Both parts carry RoHS compliance and MSL-1 ratings, confirming suitability for standard industrial and commercial applications without additional environmental or regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1705579 directly replace the 1705689 without PCB redesign?

A: Electrical and functional compatibility is complete. However, the mounting technology differs (through-hole versus press-fit), requiring PCB pad pattern modification. The terminal block itself maintains identical electrical performance and wire termination specifications.

Q: Are there any electrical performance differences between these parts?

A: No. Both components share identical current ratings (10 A), voltage ratings (300 V), wire gauge acceptance (14-30 AWG), and screw termination specifications (M2 thread, 0.22-0.25 Nm torque).

Q: Why is the 1705689 classified as obsolete?

A: The 1705689 belongs to the COMBICON EMKDS series, which has been superseded by the active COMBICON MKDSD series. The 1705579 represents the current production equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1705689 and 1705579 are RoHS compliant with MSL-1 ratings, confirming equivalent environmental and regulatory compliance.

Q: What is the impact of switching from press-fit to through-hole mounting?

A: Press-fit mounting eliminates the need for solder, while through-hole mounting requires standard PCB soldering. This affects assembly process and PCB design but does not alter electrical specifications or wire termination performance.
