Phoenix Contact 1981966 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1981966 is a 9-position terminal block plug with male pins, 0.200" (5.08mm) pitch, designed for 180° free-hanging in-line applications. This component features screwless push-in spring termination and supports wire gauges from 12-26 AWG (0.2-2.5mm²). The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1981966 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (12A IEC / 10A UL), voltage rating (630V IEC / 300V UL), and wire gauge acceptance (12-26 AWG / 0.2-2.5mm²) must be identical or exceed the original specification.
• Mechanical Compatibility: Number of positions (9), pitch (0.200" / 5.08mm), plug wire entry angle (180°), and mounting type (free-hanging in-line) must match exactly.
• Termination Method: Screwless push-in spring termination must be maintained.
• Material and Certification: Housing material (Polyamide/Nylon), flammability rating (UL94 V-0), and RoHS compliance must be equivalent.

The substitute part Phoenix Contact 1873579 meets all these criteria while offering the advantage of active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1873579 is the direct functional equivalent of the 1981966. All electrical, mechanical, and material specifications are identical. The primary distinction is product lifecycle status: the 1981966 is obsolete while the 1873579 is active.

Selection of the 1873579 is supported by:

• Compliance Equivalence: Both parts maintain UL94 V-0 flammability rating and RoHS compliance.
• Electrical Equivalence: Identical current and voltage ratings across both IEC and UL standards ensure direct substitution in existing circuit designs.
• Mechanical Equivalence: Identical pitch, position count, wire entry angle, and mounting configuration ensure physical compatibility with existing connector housings and PCB layouts.
• Availability: The active product status of 1873579 ensures long-term procurement viability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1873579 directly replace the 1981966 in existing assemblies?

A: Yes. The 1873579 is mechanically and electrically identical to the 1981966 across all specified parameters. No design modifications are required for direct substitution.

Q: What is the difference between the COMBICON FKICS and COMBICON FKIC series?

A: Both series employ identical electrical and mechanical specifications for this 9-position, 5.08mm pitch plug configuration. The series designation reflects product line evolution; the FKIC series represents the current active product line.

Q: Are there any packaging differences between these parts?

A: The 1981966 is supplied in standard packaging, while the 1873579 is supplied in bulk packaging. This does not affect component functionality or compatibility.

Q: What wire gauges are compatible with this terminal block plug?

A: Both the 1981966 and 1873579 accept wire gauges from 12-26 AWG, equivalent to 0.2-2.5mm² cross-sectional area.

Q: Is the 1873579 RoHS compliant?

A: Yes. The 1873579 maintains full RoHS compliance and UL94 V-0 flammability certification, identical to the original 1981966.

Q: Why is the 1981966 listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle management. The 1873579 represents the current active equivalent within the Phoenix Contact COMBICON terminal block product portfolio.
