Phoenix Contact 1730683 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1730683 is a 9-position wire-to-board terminal block with horizontal mating orientation and 5.08mm pitch, designed for through-hole PCB mounting. This component operates at 10A/300V with screw-type rising cage clamp termination and accepts wire gauges from 12-30 AWG. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1730683 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (10A), voltage rating (300V), and wire gauge acceptance (12-30 AWG) must be identical
• Physical Configuration: 9 positions, 5.08mm pitch, horizontal mating orientation, and through-hole mounting must match exactly
• Termination Method: Screw-type rising cage clamp with M3 thread and 0.5-0.6 Nm torque specification
• Material Composition: Polyamide (PA) nylon housing
• Regulatory Compliance: RoHS and REACH status

The Phoenix Contact 1730463 meets all substitution criteria as a functionally equivalent alternative, with the primary distinction being product status (active vs. obsolete) and series designation (COMBICON MKDS vs. COMBICON EMKDS).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1730463 is the direct functional equivalent for the obsolete 1730683. Both components share identical electrical ratings, physical dimensions, termination specifications, and material composition. The 1730463 maintains active product status with current manufacturing support, making it the appropriate selection for new designs and ongoing procurement requirements.

Both parts carry equivalent regulatory compliance: the 1730683 is ROHS3 compliant while the 1730463 is RoHS compliant, with both rated MSL 1 (unlimited moisture sensitivity). The series designation change from COMBICON EMKDS to COMBICON MKDS reflects Phoenix Contact's product line evolution while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1730463 be used as a direct replacement for the 1730683 in existing designs?

A: Yes. The 1730463 is electrically and mechanically equivalent across all critical parameters: 9 positions, 5.08mm pitch, 10A/300V ratings, M3 screw termination, and through-hole mounting. PCB footprints and wire termination procedures are identical.

Q: What is the significance of the series change from COMBICON EMKDS to COMBICON MKDS?

A: The series designation reflects Phoenix Contact's product line organization. Both series employ identical electrical specifications, housing materials, and termination methods. The change does not affect functional compatibility or performance characteristics.

Q: Are there packaging differences between these parts?

A: The 1730683 is listed with unspecified packaging, while the 1730463 is supplied in bulk packaging. Both parts maintain the same electrical and mechanical specifications regardless of packaging configuration.

Q: What wire gauges are compatible with both terminal blocks?

A: Both the 1730683 and 1730463 accept wire gauges from 12-30 AWG. Screw torque specification of 0.5-0.6 Nm (4.4-5.3 Lb-In) applies uniformly across the supported wire gauge range.

Q: Are both parts RoHS compliant?

A: Yes. The 1730683 is ROHS3 compliant and the 1730463 is RoHS compliant. Both meet current regulatory requirements for hazardous substance restrictions.
