Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1770429 is determined by the following critical parameters that must align between the main part and substitute components:

• Electrical Compatibility: Current rating (51A minimum), voltage rating (300V minimum), and wire gauge acceptance range
• Mechanical Compatibility: 5-position configuration, 10mm pitch spacing, horizontal PCB mounting orientation, and through-hole mounting type
• Termination Method: Screwless spring-based wire termination systems
• Physical Form Factor: Lever-actuated operation and green housing color
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The Phoenix Contact 1119814 qualifies as a substitute based on matching these core parameters while offering active product status and extended operating temperature range.

Engineering Selection Recommendations

The Phoenix Contact 1119814 is the qualified substitute for the obsolete 1770429 based on the following engineering criteria:

Product Status Alignment: The 1119814 maintains active product status with current manufacturing support, ensuring long-term component availability and supply chain continuity compared to the obsolete 1770429.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements without modification to existing certifications or documentation.

Electrical and Mechanical Specifications: The 1119814 meets or exceeds all critical electrical parameters (current, voltage) and maintains identical mechanical form factor (5 positions, 10mm pitch, through-hole mounting, horizontal orientation).

Wire Gauge Compatibility: The 1119814 accepts a wider wire gauge range (4-18 AWG versus 6-18 AWG), providing enhanced flexibility for wire selection without compromising the original design intent.

Termination Technology: Both components employ screwless spring-based termination methods, ensuring compatible installation procedures and eliminating the need for tool changes or process modifications.

Frequently Asked Questions (FAQ)

Q: Can the 1119814 be used as a direct replacement for the 1770429 in existing designs?

A: Yes. The 1119814 maintains identical pitch spacing (10mm), position count (5), mounting orientation (horizontal), and mounting type (through-hole). The screwless spring termination method is compatible with existing wire preparation and installation procedures. PCB footprints designed for the 1770429 will accommodate the 1119814 without modification.

Q: What is the difference in wire termination between these two parts?

A: The 1770429 uses spring cage with tension clamp termination, while the 1119814 uses leg spring with push-in spring termination. Both are screwless spring-based systems that eliminate the need for screwdriver tools. The 1119814 termination method is compatible with standard wire insertion procedures.

Q: Does the 1119814 support the same wire gauge range as the 1770429?

A: The 1119814 supports a wider range (4-18 AWG) compared to the 1770429 (6-18 AWG). This expanded capability is fully backward compatible with designs using 6-18 AWG wire, with no performance degradation.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. No additional certifications or compliance documentation changes are required when substituting the 1119814 for the 1770429.

Q: What packaging is available for the 1119814?

A: The 1119814 is supplied in box packaging. Inventory availability is confirmed at 966 pieces in new original condition.

Q: Why should the 1119814 be selected over the obsolete 1770429?

A: The 1119814 is an active product with ongoing manufacturing support, ensuring reliable long-term availability. It provides extended operating temperature range (-40°C to 105°C) and maintains all functional and mechanical compatibility with the original design.
