CDL4U/G Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The CDL4U/G 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/G accommodates wire gauges from 10-22 AWG (0.5-4mm²) and is rated for 35A at 600V under UL standards and 32A at 400V under IEC standards. Due to its obsolete status, sourcing active alternatives ensures supply chain continuity and compliance with current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

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

Mechanical Compatibility:

• Number of positions: 4
• Number of levels: 2
• Terminal width: 6.0mm
• Termination style: Screw
• Insulation material: Polyamide (PA66), Nylon 6/6
• Color: Green
• Stripping length: 9mm

Electrical Compatibility:

• Wire gauge range: 10-22 AWG minimum
• Current rating (UL): 35A minimum
• Voltage rating (UL): 600V minimum
• Current rating (IEC): 32A minimum
• Voltage rating (IEC): 400V minimum

The CDL4UN/G meets all mechanical and electrical compatibility criteria, with enhanced voltage rating under IEC standards (800V versus 400V) and expanded wire gauge range (0.2-4mm² versus 0.5-4mm²), making it a direct functional equivalent with superior specifications.

Parameter Comparison

Engineering Selection Recommendations

The CDL4UN/G is the direct active equivalent for the obsolete CDL4U/G. Selection of CDL4UN/G is supported by the following engineering factors:

Product Status: CDL4UN/G maintains active product status with current manufacturing support, whereas CDL4U/G is obsolete and subject to supply discontinuation.

Regulatory Compliance: CDL4UN/G carries ROHS3 compliance certification and REACH unaffected status, providing documented adherence to current environmental and chemical safety regulations. The CDL4U/G does not provide equivalent compliance documentation.

Electrical Performance: CDL4UN/G meets or exceeds all electrical specifications of CDL4U/G. The IEC voltage rating of 800V on CDL4UN/G provides additional margin over the 400V requirement of CDL4U/G.

Wire Gauge Compatibility: CDL4UN/G supports wire gauges from 0.2-4mm², extending the lower gauge limit compared to CDL4U/G (0.5-4mm²), providing greater application flexibility without compromising upper-range compatibility.

Mechanical Compatibility: All mechanical parameters—position count, level configuration, terminal width, termination method, insulation material, color, and stripping length—are identical between the two parts, ensuring direct physical and functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CDL4UN/G be used as a direct replacement for CDL4U/G in existing assemblies?

A: Yes. CDL4UN/G is mechanically and electrically equivalent to CDL4U/G across all critical parameters. The identical 4-position, dual-level configuration, 6.0mm terminal width, screw termination, and electrical ratings (35A at 600V UL, 32A at 400V IEC) ensure direct interchangeability. Physical mounting and wire connection procedures remain unchanged.

Q: What are the key differences between CDL4U/G and CDL4UN/G?

A: The primary differences are product status and compliance documentation. CDL4UN/G is active with ROHS3 and REACH compliance certifications, while CDL4U/G is obsolete without equivalent compliance documentation. CDL4UN/G also provides enhanced IEC voltage rating (800V versus 400V) and expanded wire gauge range (0.2-4mm² versus 0.5-4mm²).

Q: Does packaging differ between CDL4U/G and CDL4UN/G?

A: Yes. CDL4U/G is supplied in unspecified packaging, while CDL4UN/G is supplied in bulk packaging. Verify bulk packaging specifications against your assembly and handling requirements.

Q: Are there any wire gauge limitations when substituting CDL4UN/G for CDL4U/G?

A: No. CDL4UN/G supports the full 10-22 AWG range required by CDL4U/G applications. The expanded lower limit (0.2mm² versus 0.5mm²) on CDL4UN/G provides additional flexibility for smaller gauge applications without affecting compatibility with existing 10-22 AWG wire specifications.

Q: What compliance certifications apply to CDL4UN/G?

A: CDL4UN/G carries ROHS3 compliance certification and is REACH unaffected. These certifications document compliance with current environmental and chemical safety regulations applicable to electronic components.

Q: Is CDL4UN/G suitable for both UL and IEC applications?

A: Yes. CDL4UN/G meets both UL standards (35A at 600V) and IEC standards (32A at 800V), making it suitable for applications requiring either or both certification standards.
