Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1948776 is based on strict equivalence across the following critical parameters:

• Connector Type & Configuration: 8-position plug with female sockets, COMBICON MSTB series
• Pitch & Spacing: 0.200" (5.08mm) pitch maintained for mechanical compatibility
• Termination Method: Screw-type rising cage clamp termination
• Wire Entry Orientation: 180° free-hanging in-line configuration
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification
• Wire Gauge Compatibility: Support for 12-30 AWG (0.2-2.5mm²) wire range
• Compliance & Certifications: UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1778043 qualifies as a direct substitute based on these parameters. Both components share identical mechanical interfaces, termination architecture, and wire gauge specifications. The substitute part is active in production, addressing the obsolescence status of the original part.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778043 is the appropriate substitute for the obsolete 1948776 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical 8-position, 5.08mm pitch configurations with matching screw-type rising cage clamp termination. The M3 screw specification and 180° wire entry orientation ensure direct mechanical interchangeability in existing installations.

Electrical Performance: The substitute part exceeds the original electrical ratings. The 1778043 provides 630V IEC rating (versus 250V on the original) and 15A UL current rating (versus 10A), delivering enhanced performance margins for the same application envelope.

Compliance & Production Status: The 1778043 carries active production status with ROHS3 compliance, addressing supply chain continuity concerns associated with the obsolete 1948776. Both components maintain UL94 V-0 flammability certification, ensuring equivalent safety performance.

Wire Gauge & Termination: Identical wire gauge support (12-30 AWG / 0.2-2.5mm²) and screw termination specifications confirm functional equivalence for conductor accommodation and connection reliability.

Frequently Asked Questions (FAQ)

Q: Can the 1778043 directly replace the 1948776 in existing applications?

A: Yes. Both components share identical mechanical interfaces, pitch specifications, and termination methods. The 1778043 provides equal or superior electrical ratings, ensuring compatibility with applications designed for the 1948776.

Q: What are the key differences between these parts?

A: The primary differences are product status and electrical ratings. The 1948776 is obsolete; the 1778043 is active production. The 1778043 offers higher voltage rating (630V IEC versus 250V) and higher current rating (15A UL versus 10A UL), while maintaining identical mechanical specifications.

Q: Are there packaging differences between the two parts?

A: Yes. The 1948776 was supplied with unspecified packaging; the 1778043 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or compatibility.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the 1948776 and 1778043 accommodate 12-30 AWG (0.2-2.5mm²) wire gauges, ensuring identical conductor compatibility and termination performance.

Q: What compliance certifications apply to the substitute part?

A: The 1778043 carries ROHS3 compliance and UL94 V-0 flammability certification. The original 1948776 was RoHS Compliant with UL94 V-0 rating. Both meet equivalent safety and environmental standards for industrial terminal block applications.

Q: Is the screw torque specification the same for both parts?

A: The 1948776 does not specify screw torque. The 1778043 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) for M3 screw termination, providing defined assembly guidance for the substitute part.
