Phoenix Contact 3003473 Terminal Block Ground Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3003473 is a 2-position ground terminal block connector designed for wire gauges 14-26 AWG (0.14-2.5 mm²). This component belongs to the CLIPLINE MZFK series and features push-in spring termination with polyamide insulation rated UL94 V-0. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3003473 is determined by the following critical parameters:

• Connector Type & Function: Ground/earth terminal block with 2 positions and 1 level
• Terminal Geometry: 5.2 mm terminal width for mechanical compatibility
• Termination Method: Push-in spring mechanism for consistent wire retention
• Wire Gauge Compatibility: Acceptable wire gauge range must encompass or exceed the original 14-26 AWG specification
• Insulation Material & Rating: Polyamide (PA) with UL94 V-0 flammability rating for safety compliance
• Color Coding: Green and yellow earth/ground identification
• Moisture & Environmental Compliance: MSL 1 rating and RoHS compliance for reliability

The Phoenix Contact 3209536 qualifies as a substitute based on these parameters. While it belongs to the CLIPLINE PT series (active product status) rather than the obsolete CLIPLINE MZFK series, it maintains functional and mechanical equivalence through matching terminal width, termination style, insulation material, flammability rating, and color coding. The 3209536 supports an expanded wire gauge range (12-26 AWG, 0.14-4 mm²) that fully encompasses the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3209536 is the qualified substitute for the obsolete 3003473 based on the following engineering criteria:

Functional Equivalence: Both components share identical connector type, position count, level configuration, terminal geometry, and termination mechanism. This ensures direct mechanical and electrical compatibility in applications originally designed for the 3003473.

Compliance & Certification: The 3209536 maintains the same UL94 V-0 flammability rating and polyamide insulation material, ensuring equivalent safety performance. The upgrade from RoHS Compliant to ROHS3 Compliant status reflects current regulatory alignment without compromising component functionality.

Wire Gauge Capability: The 3209536 supports wire gauges from 12-26 AWG (0.14-4 mm²), which fully encompasses the original 14-26 AWG specification. This expanded range provides additional flexibility for applications requiring smaller gauge conductors.

Product Availability: The 3209536 is active in production with 2300 units in stock, ensuring reliable supply for both new designs and replacement applications, whereas the 3003473 is obsolete.

Series Transition: Migration from the CLIPLINE MZFK series to the CLIPLINE PT series represents a product line evolution while maintaining backward compatibility through identical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3209536 directly replace the 3003473 in existing installations?

A: Yes. Both components have identical terminal width (5.2 mm), push-in spring termination, 2-position configuration, and UL94 V-0 polyamide insulation. Mechanical and electrical compatibility is assured.

Q: What is the significance of the expanded wire gauge range in the 3209536?

A: The 3209536 accepts wire gauges 12-26 AWG compared to the original 14-26 AWG. This expanded lower limit allows connection of smaller gauge conductors (12-13 AWG) if required by system design, while maintaining full compatibility with the original 14-26 AWG range.

Q: Are there any differences in stripping length between the two parts?

A: The 3003473 specifies 9 mm stripping length, while the 3209536 specifies 10 mm. This 1 mm difference reflects the design evolution between series but does not affect substitution compatibility for standard installation practices.

Q: Does the ROHS3 compliance of the 3209536 affect compatibility with the original 3003473 specification?

A: No. ROHS3 compliance is a regulatory enhancement that ensures the 3209536 meets current environmental standards. It does not alter electrical or mechanical performance relative to the original RoHS Compliant 3003473.

Q: What is the packaging difference between these components?

A: The 3003473 packaging is not specified in the technical data. The 3209536 is supplied in box packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Are both components suitable for ground/earth applications?

A: Yes. Both the 3003473 and 3209536 are designated as Ground, Earth type terminal blocks with green and yellow color coding for proper earth/ground circuit identification.
