Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1770416 is determined by the following critical parameters:

• Position count and pitch: Both main and substitute parts must maintain 4 positions at 0.394" (10.00mm) spacing to ensure PCB layout compatibility
• Mounting configuration: Through-hole horizontal orientation with board is required for mechanical fit
• Wire termination method: Screwless spring-based termination systems are functionally equivalent
• Electrical ratings: Current and voltage ratings must meet or exceed the original specification
• Wire gauge compatibility: The acceptable wire gauge range determines conductor compatibility
• Lever actuation: Side-entry lever-actuated design is maintained across substitutes

The Phoenix Contact 1119812 (LPT series) satisfies these substitution criteria while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1119812 is the designated substitute for the obsolete 1770416 based on the following factors:

• Product lifecycle: The 1119812 maintains active product status, ensuring long-term availability and supply chain continuity
• Regulatory compliance: Both components are RoHS compliant; the 1119812 carries ROHS3 certification and REACH unaffected status, meeting current environmental standards
• Mechanical compatibility: Identical pitch, position count, and through-hole mounting configuration ensure direct PCB layout compatibility
• Electrical equivalence: The 1119812 supports the required wire gauge range (4-18 AWG vs. 6-18 AWG), providing broader conductor compatibility
• Termination method: Both employ screwless spring-based wire termination, maintaining operational consistency

Frequently Asked Questions (FAQ)

Q: Can the 1119812 be used as a direct replacement for the 1770416 in existing PCB designs?

A: Yes. Both components share identical pitch (10.00mm), position count (4), and through-hole mounting configuration. PCB footprints are compatible without modification.

Q: What is the difference in wire gauge acceptance between these parts?

A: The 1770416 accepts 6-18 AWG wire, while the 1119812 accepts 4-18 AWG wire. The 1119812 supports a broader range, including heavier gauge conductors (4-5 AWG).

Q: Are the termination methods functionally equivalent?

A: Both components use screwless spring-based termination. The 1770416 employs tension clamp technology, while the 1119812 uses leg spring and push-in spring methods. Both eliminate the need for screwdriver tools and provide reliable wire retention.

Q: Why is the 1770416 listed as obsolete?

A: The COMBICON PLH series has been superseded by newer product lines. The LPT series (1119812) represents the current generation with enhanced compliance certifications and extended operating temperature range (-40°C to 105°C).

Q: Are there packaging differences between these parts?

A: The 1770416 packaging specification is not provided. The 1119812 is supplied in box packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet current environmental regulations?

A: Yes. Both are RoHS compliant. The 1119812 additionally carries ROHS3 certification and REACH unaffected status, confirming compliance with current EU environmental directives.
