Phoenix Contact 2800318 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2800318 is a 4-position, 2-level terminal block connector rated for 12-24 AWG wire gauges with screw termination. Designed for the CLIPLINE UKK series, this component operates at 26 A (IEC) and 400V (IEC), featuring gray polyamide insulation with UL94 V-2 flammability rating.

The 2800318 is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains system reliability when original inventory is depleted or procurement becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2800318 is determined by the following critical parameters:

• Position and Level Configuration: 4 positions, 2 levels (mechanical compatibility with mounting and spacing)
• Wire Gauge Compatibility: 12-24 AWG minimum requirement; substitutes accepting 12-26 AWG maintain backward compatibility
• Current and Voltage Ratings: 26 A (IEC) and 400V (IEC) minimum; equal or higher ratings are acceptable
• Termination Method: Screw termination required for installation compatibility
• Insulation Material and Flammability: Polyamide (PA) with UL94 V-2 rating ensures electrical safety and thermal performance
• Series Compatibility: CLIPLINE UKK series maintains mechanical and electrical consistency
• Terminal Width: 6.0 mm baseline; minor variations (6.2 mm) remain functionally compatible within the same series

The substitute part 2800318 → 2800004 satisfies all critical substitution criteria while offering enhanced product status (Active vs. Obsolete) and extended wire gauge acceptance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2800004 is the direct substitute for the obsolete 2800318 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical current (26 A IEC) and voltage (400V IEC) ratings, ensuring no derating or circuit redesign is required.

Mechanical Compatibility: Identical position (4) and level (2) configuration with matching screw termination and stripping length (8 mm) ensures drop-in replacement capability within existing mechanical assemblies.

Wire Gauge Enhancement: The 2800004 accepts 12-26 AWG versus the 2800318's 12-24 AWG, providing expanded wire gauge compatibility without compromising the original specification range.

Compliance Status: The 2800004 carries ROHS3 Compliant and REACH Affected designations, meeting current regulatory requirements. The 2800318's RoHS Compliant status is superseded by the more current ROHS3 standard.

Product Lifecycle: The 2800004 is Active status, ensuring long-term availability, technical support, and supply chain continuity compared to the Obsolete 2800318.

Series Consistency: Both components belong to the CLIPLINE UKK series, maintaining design integrity and interchangeability within modular terminal block systems.

Frequently Asked Questions (FAQ)

Q: Can the 2800004 directly replace the 2800318 in existing designs?

A: Yes. The 2800004 is mechanically and electrically equivalent with identical position count, level configuration, current rating, voltage rating, and termination method. The 0.2 mm increase in terminal width (6.0 mm to 6.2 mm) remains within CLIPLINE UKK series tolerances and does not affect mounting or spacing.

Q: What is the significance of the extended wire gauge range (12-26 AWG vs. 12-24 AWG)?

A: The 2800004 accepts wire gauges up to 26 AWG, providing backward compatibility with the 2800318's 12-24 AWG specification while enabling connection of smaller gauge conductors. This does not compromise the original design intent and expands application flexibility.

Q: Are there packaging differences between the 2800318 and 2800004?

A: The 2800318 packaging is listed as unspecified, while the 2800004 is supplied in Bulk packaging. Verify bulk packaging compatibility with your procurement and assembly processes.

Q: Does the ROHS3 compliance of the 2800004 affect compatibility with RoHS Compliant designs?

A: No. ROHS3 Compliant status represents an updated regulatory designation and is fully backward compatible with systems designed to RoHS Compliant specifications. The 2800004 meets or exceeds all RoHS requirements applicable to the 2800318.

Q: Are there any functional differences between the 2800318 and 2800004?

A: The 2800004 includes Disconnect and Feed Through functionality with Switch/Knife disconnect type, which the 2800318 does not specify. This represents an enhancement rather than a deviation, providing additional operational flexibility without affecting basic terminal block functionality.

Q: What is the MSL (Moisture Sensitivity Level) difference?

A: The 2800318 lists MSL as Not Applicable, while the 2800004 specifies MSL 1 (Unlimited). This indicates the 2800004 has no moisture sensitivity restrictions and can be stored and handled without special environmental controls.
