Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1770542 is determined by strict alignment of the following critical parameters:

• Pitch and Position Count: 0.591" (15.00mm) pitch with 3 positions per level ensures PCB footprint compatibility
• Mating Orientation: Horizontal with board mounting maintains mechanical fit and electrical connectivity
• Mounting Type: Through-hole configuration preserves assembly compatibility
• Wire Gauge Acceptance: 4-18 AWG range defines compatible conductor sizes
• Electrical Ratings: Current and voltage specifications establish safe operating limits
• Termination Method: Wire termination type affects installation procedures and mechanical reliability
• Housing Material and Color: Polyamide nylon construction with green color ensures physical and environmental consistency
• Compliance Standards: RoHS and MSL ratings confirm regulatory and environmental suitability

The Phoenix Contact 1119819 qualifies as a substitute based on matching these core parameters across all critical dimensions.

Engineering Selection Recommendations

The Phoenix Contact 1119819 is the qualified substitute for the obsolete 1770542 based on the following engineering criteria:

Product Availability: The 1770542 is obsolete with no ongoing manufacturing. The 1119819 is an active product with current inventory availability, ensuring supply chain continuity.

Compliance Enhancement: Both parts maintain RoHS compliance. The 1119819 carries ROHS3 certification, representing current regulatory standards and providing enhanced environmental compliance assurance.

Electrical and Mechanical Equivalence: All critical parameters align—pitch, position count, wire gauge range, mounting configuration, and housing material are identical. Both employ screwless spring-based wire termination systems, ensuring functional compatibility despite different spring mechanism designs.

Thermal Performance: The 1119819 specifies an operating temperature range of -40°C to 105°C, providing defined thermal boundaries for system design. The 1770542 does not specify operating temperature limits.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) ratings, confirming equivalent environmental robustness.

Selection of the 1119819 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing PCB designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Will the 1119819 fit the same PCB footprint as the 1770542?

A: Yes. Both parts share identical pitch (15mm), position count (3), and through-hole mounting configuration. PCB layouts designed for the 1770542 require no modification to accommodate the 1119819.

Q: Are the wire termination methods interchangeable?

A: Both parts use screwless spring-based termination systems. The 1770542 employs spring cage with tension clamp; the 1119819 uses leg spring with push-in spring. Both accept 4-18 AWG conductors and provide equivalent electrical connection reliability. Installation procedures may differ slightly due to spring mechanism design variations.

Q: Does the 1119819 meet the same electrical specifications?

A: The 1119819 matches the 1770542 in wire gauge acceptance (4-18 AWG) and pitch configuration. The 1770542 specifies 66 A current and 600 V voltage ratings; the 1119819 does not list these specific values in the provided data. Verify current and voltage requirements against the 1119819 datasheet for your application.

Q: What is the packaging difference?

A: The 1770542 packaging is not specified. The 1119819 is supplied in box packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Is the 1119819 RoHS compliant?

A: Yes. The 1119819 carries ROHS3 compliance, which exceeds the RoHS compliance of the obsolete 1770542. Both parts meet current environmental and regulatory standards.

Q: Can I use the 1119819 in applications requiring -40°C to 105°C operation?

A: Yes. The 1119819 is rated for -40°C to 105°C operation. The 1770542 does not specify operating temperature limits. If your application requires defined thermal performance, the 1119819 provides explicit temperature boundaries.
