Phoenix Contact 1768859 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1768859 is a 12-position terminal block plug with female sockets, 5mm pitch, and 225° wire entry orientation. This component is classified as Active product status and is designed for screw-terminated connections in industrial control and automation applications. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and connector geometry align with the original specification, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1768859 is determined by the following critical parameters:

• Connector Type & Position Count: 12-position plug with female sockets
• Pitch Specification: 0.197" (5.00mm) center-to-center spacing
• Termination Method: Screw-based rising cage clamp technology
• Electrical Ratings: Minimum 15 A (UL) and 300 V (UL) capability
• Wire Gauge Compatibility: Support for 12-30 AWG conductor range
• Screw Interface: M3 screw size for terminal connection
• Flammability & Compliance: UL94 V-0 material rating and ROHS3 compliance

The substitute part TE Connectivity AMP Connectors 1-796640-2 meets these core substitution criteria. However, the wire entry angle differs (180° versus 225°), which represents a mechanical orientation variation that may affect physical installation geometry in space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1768859 and TE Connectivity 1-796640-2 maintain Active product status and satisfy ROHS3 compliance and UL94 V-0 flammability requirements. Electrical performance parameters—current capacity (15 A UL), voltage rating (300 V UL), and screw termination interface (M3)—are equivalent between both components.

The primary differentiation factor is wire entry angle: the Phoenix Contact part specifies 225° orientation, while the TE Connectivity substitute provides 180° orientation. This geometric difference requires verification against the physical installation envelope and wire routing constraints of the target application. When wire entry angle is not a limiting factor in the assembly design, the TE Connectivity part provides functional equivalence with identical electrical and mechanical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796640-2 directly replace the Phoenix Contact 1768859 in all applications?

A: Electrical and screw termination compatibility is confirmed. However, the 180° wire entry angle of the TE Connectivity part differs from the 225° specification of the Phoenix Contact original. Physical installation geometry must be evaluated to confirm the substitute orientation is compatible with the application's wire routing and enclosure layout.

Q: Are the wire gauge specifications compatible between these parts?

A: Both parts accept 12-30 AWG conductors. The TE Connectivity part specifies a broader metric range (0.05-3mm²) compared to the Phoenix Contact specification (0.2-2.5mm²). For conductors within the 0.2-2.5mm² range, both parts are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Phoenix Contact 1768859 and TE Connectivity 1-796640-2 are ROHS3 compliant and carry UL94 V-0 material flammability ratings. Electrical ratings (15 A UL, 300 V UL) are identical.

Q: What is the significance of the different torque specifications listed?

A: The Phoenix Contact part specifies 0.5-0.6 Nm screw torque, while the TE Connectivity part specifies 0.79 Nm. Both values fall within acceptable ranges for M3 screw termination. The TE Connectivity specification represents a higher torque value; follow the substitute part's torque recommendation when performing terminal connections.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in Bulk packaging. Inventory availability differs: Phoenix Contact 1768859 has 819 units in stock, while TE Connectivity 1-796640-2 has 2543 units available. Sourcing decisions may be influenced by delivery timeline requirements.
