Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777989 is a direct functional equivalent to the obsolete 1948718 terminal block plug. Both components share identical mechanical and electrical specifications across all critical parameters, including pitch, termination style, wire gauge compatibility, and flammability rating.

The 1777989 offers enhanced electrical performance with IEC voltage rating of 630V (versus 320V) and UL current rating of 15A (versus 10A), providing additional safety margin in applications requiring higher electrical stress tolerance. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

The 1777989 carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Packaging is supplied in bulk format, which may require adjustment to inventory management procedures if the original part was supplied in alternative packaging configurations.

Mechanical compatibility is assured through identical screw size (M3), torque specification (0.5-0.6 Nm), wire strip length (7mm), and insulation height (0.591"). The mating flange feature on the 1777989 provides additional mechanical stability without compromising form factor or mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777989 be used as a direct replacement for the 1948718 in existing applications?

A: Yes. The 1777989 meets all mechanical and electrical specifications of the 1948718. Identical pitch (5.08mm), wire gauge range (12-30 AWG), termination style (screw rising cage clamp), and mounting configuration (free hanging in-line) ensure direct compatibility. The 1777989 exceeds the electrical ratings of the original part, providing enhanced performance margin.

Q: What are the key differences between these two parts?

A: The primary differences are product status and electrical ratings. The 1948718 is obsolete with 320V IEC and 10A UL ratings. The 1777989 is active with 630V IEC and 15A UL ratings. Both parts are mechanically and functionally identical in all other respects, including housing material, flammability rating, screw specifications, and wire compatibility.

Q: Does the mating flange feature on the 1777989 affect compatibility?

A: No. The mating flange is an additional feature that enhances mechanical stability without altering the core form factor or mounting interface. The part remains compatible with existing connector housings and mounting configurations designed for the 1948718.

Q: Are there any compliance or certification differences?

A: The 1777989 carries ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. The 1948718 specifications do not include these certifications. Both parts maintain UL94 V-0 flammability rating and identical electrical safety specifications.

Q: What is the packaging difference between these parts?

A: The 1948718 was supplied in standard packaging, while the 1777989 is supplied in bulk packaging. This may require adjustment to receiving, storage, and inventory management procedures but does not affect component functionality or performance.

Q: Can the 1777989 handle higher voltage and current than the 1948718?

A: Yes. The 1777989 is rated for 630V IEC (versus 320V) and 15A UL (versus 10A). These higher ratings provide additional electrical stress tolerance and safety margin in applications operating near the original part's rated limits.

Q: Is the wire strip length identical between both parts?

A: Yes. Both parts specify 7mm wire strip length, ensuring identical wire preparation requirements and termination procedures.

Q: Are the screw torque specifications the same?

A: Yes. Both parts require M3 screws with torque specification of 0.5-0.6 Nm (4.4-5.3 Lb-In), ensuring identical assembly procedures and connection reliability.
