CDL4U/BG Terminal Block Feed-Through Connector Equivalent & Substitute Parts

Part Overview

The CDL4U/BG is a 4-position, 2-level feed-through terminal block connector manufactured by Altech Corporation, rated for 35A (UL) and 600V (UL). This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and component procurement.

The CDL4U/BG serves as a screw-terminated connection point for wire gauges 10-22 AWG (0.5-4mm²) in beige polyamide insulation. Due to its obsolete status, sourcing equivalent or substitute components is necessary to ensure design continuity and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDL4U/BG is determined by the following critical parameters:

• Connector Configuration: 4 positions, 2 levels, feed-through type
• Termination Method: Screw termination
• Terminal Dimensions: 6.0mm width
• Electrical Ratings: Minimum 35A (UL) and 600V (UL)
• Wire Compatibility: 10-22 AWG (0.5-4mm²)
• Physical Form Factor: Beige polyamide insulation
• Stripping Length: 9mm

The CDL4UN/BG meets all substitution criteria as it maintains identical configuration, termination style, terminal width, position count, level count, wire gauge compatibility, color, insulation material, and stripping length. Electrical ratings are equal or exceed the original specification.

Parameter Comparison

Engineering Selection Recommendations

The CDL4UN/BG is the direct substitute for the obsolete CDL4U/BG. Both components share identical mechanical and electrical specifications across all critical parameters. The CDL4UN/BG offers the additional advantage of active product status, ensuring continued availability and supply chain reliability.

The CDL4UN/BG carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. These certifications support long-term design compliance and system qualification.

The expanded wire gauge range of the CDL4UN/BG (0.2-4mm² versus 0.5-4mm²) provides additional flexibility for applications requiring smaller conductor cross-sections while maintaining full compatibility with the original 0.5-4mm² specification range.

Frequently Asked Questions (FAQ)

Q: Can the CDL4UN/BG directly replace the CDL4U/BG in existing designs?

A: Yes. The CDL4UN/BG maintains identical configuration, electrical ratings, termination method, and physical dimensions. No design modifications are required for substitution.

Q: What is the difference between the wire gauge ranges?

A: The CDL4U/BG accepts 0.5-4mm² (10-22 AWG), while the CDL4UN/BG accepts 0.2-4mm² (10-22 AWG). The CDL4UN/BG supports an extended lower range, providing compatibility with smaller conductors. Both parts fully support the original 0.5-4mm² specification.

Q: Why is the CDL4U/BG listed as obsolete?

A: The CDL4U/BG has been discontinued by the manufacturer. The CDL4UN/BG is the active replacement product, maintaining all functional and electrical equivalence.

Q: Are there packaging differences between these parts?

A: The CDL4U/BG packaging is not specified. The CDL4UN/BG is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: What regulatory certifications apply to the CDL4UN/BG?

A: The CDL4UN/BG is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: Are both parts suitable for 600V applications?

A: Yes. Both the CDL4U/BG and CDL4UN/BG are rated for 600V (UL), making them suitable for equivalent voltage applications.
