Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1836366 qualifies as a functional substitute based on the following critical parameters:

Substitution Criteria:

• Number of Positions: Both components feature 4-position configurations, enabling direct pin-count compatibility
• Mounting Technology: Both utilize through-hole termination, maintaining PCB assembly compatibility
• Manufacturer Consistency: Both are Phoenix Contact products, ensuring design philosophy and quality standards alignment
• Electrical Rating Compatibility: The substitute part supports 12A nominal current at 320V IEC rating, meeting or exceeding typical application requirements for the original component class
• RoHS Compliance: The substitute maintains RoHS3 compliance, satisfying modern regulatory requirements

The 1836366 represents an active product within the COMBICON CCA series, providing long-term availability and supply chain stability compared to the obsolete 1963890.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The original 1963890 component is classified as obsolete, creating supply chain risk and limiting future procurement options. The substitute part 1836366 maintains active product status within the Phoenix Contact COMBICON CCA series, ensuring continued availability and manufacturer support.

Compliance Alignment: Both components satisfy RoHS compliance requirements. The substitute part carries ROHS3 certification, representing current regulatory compliance standards. REACH status for the substitute is documented as REACH Unaffected, confirming compliance with chemical substance regulations.

Electrical and Mechanical Compatibility: The 4-position configuration and through-hole mounting technology are preserved in the substitute component. The specified electrical ratings (12A at 320V IEC) provide adequate performance for standard terminal block applications. The 0.197" (5.00mm) pitch and right-angle orientation of the substitute part are standard specifications within the terminal block category.

Procurement Strategy: Transition to the Phoenix Contact 1836366 eliminates obsolescence risk while maintaining manufacturer ecosystem consistency. Current inventory availability (929 units in stock) supports immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1836366 directly replace the 1963890 in existing designs? A: Yes, the 1836366 provides functional equivalence based on 4-position configuration and through-hole mounting compatibility. However, physical layout verification is required to confirm PCB footprint alignment, particularly regarding the 90° right-angle orientation and 5.00mm pitch specifications of the substitute part.

Q: What are the key electrical differences between these components? A: The substitute part 1836366 specifies 12A nominal current at 320V IEC rating. The original 1963890 does not provide detailed electrical specifications in available documentation. Applications requiring current or voltage ratings below the substitute part's specifications will achieve adequate performance margins.

Q: Why is the original part classified as obsolete? A: The 1963890 has reached end-of-life status within Phoenix Contact's product portfolio. The COMBICON CCA series, represented by the 1836366, represents the current generation of equivalent terminal block technology from the manufacturer.

Q: Are there packaging differences between these parts? A: The original 1963890 packaging is not specified. The substitute 1836366 is supplied in bulk packaging, suitable for standard procurement and assembly workflows.

Q: What compliance certifications apply to the substitute part? A: The 1836366 carries ROHS3 compliance certification and REACH Unaffected status, confirming compliance with current environmental and chemical substance regulations applicable to electronic components.
