Frequently Asked Questions (FAQ)

Q: Can the 1730421 be used as a direct replacement for the 1730641?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 5-position configuration, 5.08mm pitch, 10A/300V ratings, through-hole mounting, and M3 screw termination. PCB layout and assembly procedures remain unchanged.

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

A: The EMKDS series (1730641) is obsolete. The MKDS series (1730421) is the active equivalent line. Both series maintain identical electrical and mechanical specifications for this 5-position, 5.08mm pitch configuration.

Q: Are there packaging differences between these parts?

A: The 1730641 was supplied in standard packaging. The 1730421 is supplied in Bulk packaging. Both are suitable for PCB assembly and field installation applications.

Q: Does the 1730421 meet current regulatory requirements?

A: Yes. The 1730421 is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The obsolete 1730641 carries RoHS Compliant status.

Q: What wire gauges are supported by the substitute part?

A: The 1730421 accepts wire gauges 12-30 AWG, identical to the 1730641. Screw torque specification remains 0.5-0.6 Nm (4.4-5.3 Lb-In) for both components.
