Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1850576 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: 18 positions at 0.200" (5.08mm) spacing
Connector Type: Plug with female sockets
Termination Method: Screw-based rising cage clamp
Mounting Configuration: Free-hanging in-line orientation
Electrical Performance: UL ratings of 15 A at 300 V minimum
Wire Compatibility: Support for 12-30 AWG conductor range
Regulatory Compliance: RoHS compliant, UL94 V-0 flammability rating

The TE Connectivity AMP Connectors 1-796634-8 meets these core substitution criteria. The primary difference is the wire entry angle (180° versus 225°), which affects physical installation geometry but does not impact electrical performance or screw-terminal functionality.

Engineering Selection Recommendations

Both the Phoenix Contact 1850576 and TE Connectivity 1-796634-8 are active production components with RoHS compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Phoenix Contact 1850576: Select when 225° wire entry geometry is required for the specific installation layout or when the lower screw torque specification (0.5-0.6 Nm) is a design constraint.

TE Connectivity 1-796634-8: Select when 180° wire entry is acceptable or preferred, when the wider wire gauge range (0.05-3mm²) provides additional flexibility, or when the specified operating temperature range (-40°C ~ 110°C) is required for the application.

Both parts support identical electrical performance (15 A at 300 V), M3 screw termination, and 18-position 5.08mm pitch configuration. The choice between them is driven by mechanical installation requirements and environmental specifications rather than electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796634-8 directly replace the Phoenix Contact 1850576 in an existing assembly?

A: Electrical and screw-terminal compatibility is confirmed. However, the 180° wire entry angle differs from the 225° angle of the Phoenix Contact part. Physical installation geometry must be evaluated to confirm the wire entry angle change does not conflict with enclosure layout or cable routing.

Q: Are there differences in screw torque specifications between these parts?

A: Yes. The Phoenix Contact 1850576 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In), while the TE Connectivity 1-796634-8 specifies 0.79 Nm (7.0 Lb-In). Installation procedures must use the correct torque value for the selected part to ensure proper contact pressure and electrical performance.

Q: What wire gauges are supported by each part?

A: Both parts support 12-30 AWG. In metric units, the Phoenix Contact part supports 0.2-2.5mm², while the TE Connectivity part supports the wider range of 0.05-3mm². For conductors within the 0.2-2.5mm² range, both parts are compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both the Phoenix Contact 1850576 and TE Connectivity 1-796634-8 are RoHS compliant with UL94 V-0 flammability ratings, meeting current regulatory requirements for industrial terminal block applications.

Q: Does the TE Connectivity part have a specified operating temperature range?

A: Yes. The TE Connectivity 1-796634-8 specifies -40°C ~ 110°C. The Phoenix Contact 1850576 does not provide an operating temperature specification in the available data. If temperature performance is critical to the application, the TE Connectivity part's specified range should be evaluated against system requirements.
