Phoenix Contact 1770539 Terminal Block - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 1770539 is a 2-position wire-to-board terminal block from the COMBICON PLH series, designed for horizontal mounting with through-hole PCB installation. This component features a 15.00mm pitch, 66A current rating, and 600V voltage rating, utilizing screwless spring cage termination with lever actuation.
The 1770539 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this terminal block.

Substitute Part Grouping Explanation
Substitution eligibility for the Phoenix Contact 1770539 is determined by strict alignment with the following critical parameters:
- Electrical Compatibility: Positions per level (2), pitch (15.00mm), current rating (66A minimum), and voltage rating (600V minimum)
- Mechanical Compatibility: Mating orientation (horizontal with board), mounting type (through hole), wire gauge acceptance (4-18 AWG)
- Termination Method: Wire termination technology must support the same wire gauge range and current capacity
- Physical Form Factor: Housing material and color consistency for PCB integration
The Phoenix Contact 1119818 meets these substitution criteria as an active product with identical pitch, position count, mating orientation, mounting type, and wire gauge specifications.

Engineering Selection Recommendations
The Phoenix Contact 1119818 (LPT series) is the identified substitute for the obsolete 1770539 (COMBICON PLH series). Selection is based on the following engineering criteria:
Electrical & Mechanical Alignment: Both components share identical pitch (15.00mm), position count (2), mating orientation, mounting method (through hole), and wire gauge specifications (4-18 AWG). These parameters ensure direct PCB footprint compatibility and wire termination compatibility.
Product Status: The 1119818 is an active product with current manufacturing support and supply availability, addressing the obsolescence of the 1770539.
Compliance: Both components are RoHS compliant. The 1119818 carries ROHS3 compliance, meeting current regulatory requirements. Both components are classified as ECCN EAR99 and share the same HTSUS code (8536.90.4000).
Termination Technology: While the 1770539 uses tension clamp termination and the 1119818 uses push-in spring termination, both employ screwless spring-based mechanisms compatible with the specified wire gauge range.
Frequently Asked Questions (FAQ)
Q: Can the 1119818 be used as a direct replacement for the 1770539 in existing designs?
A: Yes. Both components share identical pitch (15.00mm), position count (2), mating orientation (horizontal with board), mounting type (through hole), and wire gauge specifications (4-18 AWG). PCB footprints are compatible. The primary difference is the wire termination mechanism (tension clamp versus push-in spring), both of which are screwless spring-based systems.
Q: What is the current rating difference between these components?
A: The 1770539 specifies a 66A current rating. The 1119818 does not provide an explicit current rating in the available specifications. Verify the 1119818 current capacity against your application requirements before substitution.
Q: Are there voltage rating differences?
A: The 1770539 is rated for 600V. The 1119818 voltage rating is not specified in the available data. Confirm voltage compatibility with your application requirements.
Q: What is the operating temperature range for the 1119818?
A: The 1119818 operates from -40°C to 105°C. The 1770539 does not specify an operating temperature range in the available data.
Q: Are both components RoHS compliant?
A: Yes. The 1770539 is RoHS Compliant. The 1119818 is ROHS3 Compliant, meeting current regulatory standards.
Q: What packaging is available for the 1119818?
A: The 1119818 is supplied in box packaging. The 1770539 packaging specification is not provided.
