Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1730638 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (10 A), voltage rating (300 V), and wire gauge compatibility (12-30 AWG) must be identical
• Physical Configuration: 4 positions per level, 0.200" (5.08mm) pitch, and horizontal with board mating orientation must match exactly
• Termination Method: Screw-based rising cage clamp termination is required
• Mounting Interface: Through-hole PCB mounting must be maintained
• Material Composition: Polyamide (PA) nylon housing ensures mechanical and thermal consistency
• Compliance Standards: RoHS3 compliance and MSL 1 rating must be preserved

The Phoenix Contact 1730418 meets all substitution criteria as an active product alternative within the COMBICON terminal block family.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1730418 is the direct functional equivalent for the obsolete 1730638. Both components share identical electrical ratings, physical dimensions, termination methodology, and compliance certifications. The primary distinction is product status: 1730638 is obsolete while 1730418 is active and maintains current manufacturing support.

For new designs or component replenishment, the 1730418 is the appropriate selection. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment. The active status of 1730418 provides assurance of continued availability and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can the 1730418 be used as a direct replacement for the 1730638 in existing designs?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters. The 1730418 maintains the same 4-position configuration, 5.08mm pitch, 10 A current rating, 300 V voltage rating, and M3 screw termination. PCB footprints and mounting hole patterns are identical.

Q: What is the difference between the EMKDS and MKDS series designations?

A: Both designations refer to COMBICON terminal block families within Phoenix Contact's product portfolio. The MKDS series (1730418) represents the active product line, while EMKDS (1730638) is the obsolete predecessor. Electrical and mechanical specifications remain equivalent.

Q: Are there packaging differences between these parts?

A: The 1730638 is listed with unspecified packaging, while the 1730418 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not alter component functionality or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1730638 and 1730418 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.90.4000. MSL rating is 1 (unlimited) for both components.

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

A: Both components accept wire gauges from 12 to 30 AWG. Screw torque specification is 0.5-0.6 Nm (4.4-5.3 Lb-In) for proper termination across the supported wire gauge range.
