Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1730625 is based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Positions per level: 3
• Pitch: 0.200" (5.08mm)
• Mating orientation: Horizontal with Board
• Current rating: 10 A
• Voltage rating: 300 V
• Wire gauge acceptance: 12-30 AWG
• Mounting type: Through Hole
• Wire termination method: Screw - Rising Cage Clamp
• Screw thread specification: M3
• Torque specification: 0.5-0.6 Nm

The substitute part 1730405 maintains identical electrical performance and mechanical compatibility across all specified parameters. The primary distinction is the series designation (MKDS versus EMKDS) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1730405 is the direct functional equivalent for the obsolete 1730625. Both components share identical electrical ratings, mechanical dimensions, and termination specifications. The 1730405 offers the advantage of active product status, ensuring continued availability and manufacturing support.

The 1730405 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliance designation of the 1730625. Both components maintain MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

For new designs or production continuity, the 1730405 is the appropriate selection. For legacy system maintenance where original component specifications must be preserved, the 1730625 remains functionally interchangeable with the 1730405 in all electrical and mechanical aspects.

Frequently Asked Questions (FAQ)

Q: Can the 1730405 be used as a direct replacement for the 1730625?

A: Yes. Both components have identical electrical ratings (10 A, 300 V), mechanical pitch (5.08mm), wire gauge acceptance (12-30 AWG), and termination method (Screw - Rising Cage Clamp). PCB footprints and mounting hole patterns are identical.

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

A: The EMKDS series (1730625) is obsolete. The MKDS series (1730405) is the active equivalent. Both series share identical electrical and mechanical specifications for this 3-position configuration.

Q: Are there packaging differences between these parts?

A: The 1730625 is listed with unspecified packaging, while the 1730405 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or compatibility.

Q: Does the ROHS3 compliance of the 1730405 affect compatibility with designs specified for RoHS compliance?

A: No. ROHS3 compliance is a superset of RoHS compliance. The 1730405 meets all RoHS requirements and exceeds them with current regulatory standards.

Q: Are the screw torque specifications identical?

A: Yes. Both components require 0.5-0.6 Nm (4.4-5.3 Lb-In) torque for M3 screws. Installation procedures and assembly specifications remain unchanged.
