Key Parameters

Substitute Part Grouping Explanation

Substitution of the CP3LG2.5(I.S) is determined by equivalence across the following critical parameters:

Electrical Specifications: Voltage rating (500V IEC / 300V UL), wire gauge capacity (12-22 AWG / 0.34-2.5mm²), and termination method (push-in spring mechanism).

Mechanical Configuration: 6-position, 3-level feed-through terminal block design with 5.0mm terminal width and 10mm stripping length.

Material & Compliance: Polyamide (PA66) insulation, ROHS3 compliance, and REACH unaffected status.

Series Continuity: Altech Corporation CP series terminal blocks maintain functional and dimensional compatibility within the specified parameter set.

The substitute part CPTLG2.5(I.S) satisfies all critical substitution criteria while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CPTLG2.5(I.S) is the direct equivalent for CP3LG2.5(I.S) applications. This substitute maintains electrical performance, mechanical compatibility, and regulatory compliance across all specified parameters. The active product status of CPTLG2.5(I.S) ensures long-term availability and manufacturing support, addressing the obsolescence of the original part.

Compliance Basis: Both parts satisfy ROHS3 and REACH requirements, ensuring regulatory alignment for current and future production environments. Material composition and electrical ratings remain consistent between the main part and substitute.

Inventory Consideration: Current stock availability exists for both parts, supporting immediate component procurement for existing designs or transition to the active substitute for new production.

Frequently Asked Questions (FAQ)

Q: What makes CPTLG2.5(I.S) a direct substitute for CP3LG2.5(I.S)?

A: CPTLG2.5(I.S) matches all critical electrical and mechanical parameters: identical wire gauge capacity (12-22 AWG), push-in spring termination, polyamide insulation material, and regulatory compliance status (ROHS3, REACH unaffected). Both parts are Altech Corporation CP series feed-through terminal blocks with equivalent functional performance.

Q: Are there dimensional differences between these parts?

A: No dimensional differences are specified in the provided parameters. Both parts maintain the same terminal width (5.0mm), stripping length (10mm), and feed-through configuration.

Q: Why is the original part listed as obsolete?
