Engineering Selection Recommendations

The Phoenix Contact 1786831 is the direct substitute for the obsolete 1946367. Both components share identical electrical and mechanical specifications across all critical parameters. The 1786831 offers the following advantages:

Active product status ensures ongoing availability and supply chain continuity
ROHS3 compliance provides enhanced regulatory alignment compared to RoHS compliance
UL current rating of 15A (versus 10A on the original) provides additional margin in UL-regulated applications
Identical IEC ratings maintain full compatibility with IEC-based system designs
Mating flange feature on the substitute provides mechanical retention without wire-side latches

The substitute part is suitable for direct replacement in all applications where the original 1946367 was specified.

Frequently Asked Questions (FAQ)

Q: Can the 1786831 be used as a direct replacement for the 1946367?

A: Yes. Both parts share identical pitch (5mm), position count (2), wire entry angle (180°), termination method (screw rising cage clamp), mounting type (free hanging in-line), IEC current (12A), IEC voltage (630V), wire gauge range (12-30 AWG / 0.2-2.5mm²), housing material (Polyamide/Nylon), and flammability rating (UL94 V-0). The 1786831 is the active equivalent.

Q: What is the difference in UL current ratings between these parts?

A: The 1946367 is rated for 10A under UL standards, while the 1786831 is rated for 15A. Both maintain the same 12A IEC rating. The higher UL rating on the substitute provides additional capacity margin for UL-compliant applications.

Q: Are there packaging differences between these parts?

A: The 1946367 was supplied with standard packaging (not specified), while the 1786831 is supplied in bulk packaging. This difference does not affect electrical or mechanical compatibility.

Q: Do both parts have the same compliance certifications?

A: Both parts are RoHS compliant. The 1786831 carries ROHS3 compliance, which represents a more current regulatory standard. Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the significance of the mating flange feature difference?

A: The 1946367 includes both mating flange and retention latches (non-wire side), while the 1786831 includes only the mating flange. Both designs provide mechanical retention; the difference reflects design evolution in the COMBICON MSTB series without affecting functional compatibility.

Q: Are the screw torque specifications identical?

A: Yes. Both parts specify M3 screws with identical torque range of 0.5-0.6 Nm (4.4-5.3 Lb-In) and wire strip length of 7mm.
