Phoenix Contact 1705702 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1705702 is a 7-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 substitute parts is essential for ongoing system maintenance, repair, and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1705702 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Current rating: 10 A minimum
• Voltage rating: 300 V minimum
• Wire gauge acceptance: 14-30 AWG

Mechanical Compatibility:

• Position count: 7 positions
• Pitch: 0.150" (3.81mm)
• Mating orientation: Horizontal with Board
• Wire termination method: Screw - Rising Cage Clamp
• Screw specification: M2 thread with 0.22-0.25 Nm torque range

Material & Compliance:

• Housing material: Polyamide (PA), Nylon
• RoHS compliance required
• MSL rating: 1 (Unlimited)

The identified substitute part (1705595) maintains electrical and mechanical equivalence across all critical parameters. The primary difference is the mounting technology: the 1705702 uses press-fit mounting, while the 1705595 uses through-hole mounting. This distinction affects PCB design integration but does not alter electrical performance or wire termination compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1705595 is the qualified substitute for the obsolete 1705702. Both components are RoHS compliant and carry MSL rating 1, ensuring equivalent environmental and regulatory compliance.

Selection Basis:

The 1705595 maintains full electrical equivalence (10 A current, 300 V voltage, 14-30 AWG wire gauge) and mechanical compatibility (7 positions, 0.150" pitch, screw-based rising cage clamp termination, M2 thread specification). The active product status of the 1705595 ensures ongoing availability and supply chain continuity.

The mounting technology difference (press-fit versus through-hole) requires PCB design modification but does not affect electrical performance, wire termination methodology, or connector interface specifications. Through-hole mounting may provide enhanced mechanical robustness in high-vibration environments compared to press-fit technology.

Frequently Asked Questions (FAQ)

Q: Can the 1705595 directly replace the 1705702 without PCB modification?

A: No. The 1705702 uses press-fit mounting, while the 1705595 uses through-hole mounting. PCB pad layout and hole specifications must be modified accordingly. However, electrical and wire termination compatibility is maintained.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated for 10 A current, 300 V voltage, and accept 14-30 AWG wire gauges. Screw torque specifications (0.22-0.25 Nm) are identical.

Q: What is the significance of the product status difference?

A: The 1705702 is obsolete and no longer manufactured. The 1705595 is active and maintains current production status, ensuring long-term availability for new designs and replacement stock.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1705702 and 1705595 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: Do the series designations (EMKDS vs. MKDSD) indicate functional differences?

A: The series designations reflect different product lines within the Phoenix Contact COMBICON family. The functional differences are limited to mounting technology (press-fit versus through-hole). All other electrical and mechanical specifications remain equivalent.

Q: What wire termination method is used in both components?

A: Both components use screw-based rising cage clamp termination with M2 thread specification. Wire insertion and removal procedures are identical between the two parts.
