CP3LG2.5 Terminal Block Equivalent & Substitute Parts

Part Overview

The CP3LG2.5 is a DIN terminal block connector manufactured by Altech Corporation, designed for feed-through applications with push-in spring termination. This component features 6 positions across 3 levels with a single grounded connection, accommodating wire gauges from 12-22 AWG (0.34-2.5mm²). The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure procurement availability for new and legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CP3LG2.5 terminal block is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Current rating (IEC and UL standards)
• Voltage rating (IEC and UL standards)
• Wire gauge acceptance range (AWG and mm²)

Mechanical Compatibility Criteria:

• Number of positions (6)
• Number of levels (3)
• Terminal width (5.0mm)
• Termination style (Push In, Spring)
• Insulation material (Polyamide PA66/Nylon 6/6)
• Stripping length (10mm)

Regulatory and Compliance Criteria:

• RoHS3 compliance
• REACH compliance status

The substitute part CPTLG2.5 maintains identical electrical ratings, mechanical configuration, and regulatory compliance, establishing it as a direct functional equivalent. The primary distinction is product status: CPTLG2.5 is active and currently available, whereas CP3LG2.5 is obsolete.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can CPTLG2.5 be used as a direct replacement for CP3LG2.5 in existing designs?

A: Yes. Both components share identical mechanical configuration (6 positions, 3 levels, 5.0mm terminal width), termination method (push-in spring), and regulatory compliance (ROHS3, REACH unaffected). The CPTLG2.5 is the active equivalent of the obsolete CP3LG2.5.

Q: What is the primary reason for substitution?

A: The CP3LG2.5 is classified as obsolete. The CPTLG2.5 is the active manufacturer equivalent, ensuring continued availability and supply chain support.

Q: Are there differences in electrical ratings between CP3LG2.5 and CPTLG2.5?

A: Electrical rating specifications for the CPTLG2.5 are not provided in the available substitute data. For applications requiring confirmation of IEC and UL current and voltage ratings, consult the manufacturer's technical documentation for CPTLG2.5.

Q: What wire gauge range does the CPTLG2.5 accept?

A: Wire gauge specifications for the CPTLG2.5 are not provided in the available substitute data. The CP3LG2.5 accepts 12-22 AWG (0.34-2.5mm²). Confirm wire gauge compatibility with manufacturer specifications for CPTLG2.5.

Q: Are packaging options different between the two parts?

A: The CP3LG2.5 packaging is not specified in the available data. The CPTLG2.5 is supplied in bulk packaging, suitable for production and assembly environments.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CP3LG2.5 and CPTLG2.5 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
