CDL4U/Y Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The CDL4U/Y is a feed-through terminal block connector manufactured by Altech Corporation, designed for 4-position, dual-level electrical connections with screw termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations. The CDL4U/Y operates within IEC and UL standards, supporting wire gauges from 10-22 AWG and accommodating polyamide insulation materials suitable for industrial control and distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDL4U/Y is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Matching current and voltage ratings under both IEC and UL standards
• Physical Configuration: Identical number of positions (4), levels (2), and terminal width (6.0 mm)
• Termination Method: Screw-based termination style
• Wire Gauge Acceptance: Support for 10-22 AWG wire range
• Material Specification: Polyamide (PA66) or Nylon 6/6 insulation
• Connector Type: Feed-through topology

The CDL4UN/Y meets all substitution criteria as an active equivalent part, with enhanced voltage rating under IEC conditions and expanded wire gauge acceptance range.

Parameter Comparison

Engineering Selection Recommendations

The CDL4UN/Y is the direct active equivalent for the obsolete CDL4U/Y. Both components share identical electrical performance under UL standards and mechanical configuration. The CDL4UN/Y provides enhanced specifications in two areas: IEC voltage rating increased from 400 V to 800 V, and expanded wire gauge acceptance from 0.5-4 mm² to 0.2-4 mm².

The CDL4UN/Y carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial component procurement. The transition from obsolete to active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CDL4UN/Y directly replace CDL4U/Y in existing installations?

A: Yes. Both components maintain identical current ratings (32 A IEC, 35 A UL), voltage ratings under UL conditions (600 V), physical dimensions, and termination methodology. The CDL4UN/Y's enhanced IEC voltage rating (800 V vs. 400 V) and expanded wire gauge range provide additional operational margin without requiring circuit redesign.

Q: What is the difference in wire gauge acceptance between these parts?

A: The CDL4U/Y accepts 0.5-4 mm² wire cross-section, while the CDL4UN/Y accepts 0.2-4 mm². Both support 10-22 AWG. The CDL4UN/Y accommodates smaller gauge conductors, expanding application flexibility.

Q: Why is CDL4U/Y classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The CDL4UN/Y represents the active continuation of this product line, maintaining functional and electrical equivalence while incorporating current manufacturing standards and regulatory compliance.

Q: Are there packaging differences between CDL4U/Y and CDL4UN/Y?

A: CDL4U/Y packaging is not specified in available documentation. CDL4UN/Y is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Do both parts meet current regulatory standards?

A: CDL4UN/Y is ROHS3 compliant and REACH unaffected. Regulatory status for CDL4U/Y is not documented. For new designs and systems requiring current compliance certification, CDL4UN/Y is the appropriate selection.
