Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1946396 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (12A IEC, 320V IEC minimum)
Mechanical Compatibility: Identical pitch (5.00mm), number of positions (5), and connector type (plug with female sockets)
Termination Compatibility: Screw-type rising cage clamp termination with M3 screw and matching torque specification
Physical Form Factor: 180° free-hanging in-line mounting configuration
Wire Gauge Acceptance: Support for 12-30 AWG (0.2-2.5mm²) wire range
Material Standards: UL94 V-0 flammability rating compliance

The substitute part Phoenix Contact 1786860 meets all these criteria while offering enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The Phoenix Contact 1786860 is a direct functional equivalent to the 1946396. Both components share identical mechanical and electrical specifications within the COMBICON MSTB series, with matching pitch, position count, termination method, and wire gauge acceptance.

The 1786860 offers advantages in component sourcing due to its active product status, whereas the 1946396 is obsolete. The substitute part exceeds the original voltage rating (630V IEC versus 320V IEC) and current rating (15A UL versus 10A UL), providing enhanced electrical performance margins. Both components maintain UL94 V-0 flammability compliance. The 1786860 carries ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements.

Physical form factor, screw termination specifications, and wire acceptance ranges are identical, ensuring direct mechanical and electrical interchangeability in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the 1786860 directly replace the 1946396 in existing installations?

A: Yes. Both components are mechanically and electrically equivalent within the COMBICON MSTB series. Identical pitch (5.00mm), position count (5), termination method (M3 screw rising cage clamp), and wire gauge acceptance (12-30 AWG) ensure direct interchangeability. The 1786860 meets or exceeds all electrical ratings of the original part.

Q: What is the primary reason for substitution?

A: The 1946396 is obsolete. The 1786860 is an active product from the same manufacturer and series, providing continued component availability and supply chain reliability.

Q: Are there differences in electrical performance?

A: The 1786860 exceeds the original specifications. IEC voltage rating increases from 320V to 630V, and UL current rating increases from 10A to 15A. These enhancements provide greater electrical performance margins while maintaining full backward compatibility.

Q: Do both parts accept the same wire gauges?

A: Yes. Both the 1946396 and 1786860 accept 12-30 AWG wire (0.2-2.5mm²) and require identical screw torque specifications of 0.5-0.6 Nm (4.4-5.3 Lb-In).

Q: What regulatory compliance differences exist?

A: The 1786860 carries ROHS3 compliance and REACH unaffected status. The 1946396 specifications do not include these designations. Both maintain UL94 V-0 flammability rating.

Q: Is the mounting configuration identical?

A: Yes. Both components feature 180° free-hanging in-line mounting with identical form factor and mechanical interface.
