Weidmüller 7940116919 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 7940116919 is a 7-position wire-to-board terminal block with 45° mating orientation and 5.00mm pitch, designed for through-hole PCB mounting. This component is part of the Omnimate LP series and is currently in active production status. Finding equivalent substitute parts may be necessary due to supply constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance standards.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors 796690-7 qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• 7 positions per level
• 0.197" (5.00mm) pitch spacing
• 300 V voltage rating
• Through-hole PCB mounting
• M3 screw thread
• Polyamide (PA66), Nylon 6/6 housing material
• Screw-based wire termination method
• Side interlocking feature
• Same HTSUS and ECCN classification

Allowable Variations:

• Mating orientation differs (35° vs. 45°) but both are angled configurations suitable for wire-to-board connections
• Current rating is higher (17.5 A vs. 15 A), providing equivalent or superior performance
• Wire gauge range is broader (12-30 AWG vs. 12-26 AWG), accommodating the original specification
• Contact and clamp materials differ (Brass vs. Copper Alloy) but both are standard plating materials for terminal blocks
• Torque specification differs (0.79 Nm vs. 0.5-0.6 Nm) due to different clamping mechanisms

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 7940116919 and TE Connectivity 796690-7 are active production components suitable for wire-to-board terminal block applications with 7-position, 5.00mm pitch configurations.

The TE Connectivity 796690-7 carries ROHS3 compliance and REACH affected status, making it the appropriate selection for applications requiring regulatory compliance with current environmental directives. The Weidmüller 7940116919 is classified as REACH unaffected and not applicable for RoHS, which may be suitable for legacy systems or applications without regulatory compliance requirements.

Both components support the same voltage and pitch specifications. The TE Connectivity substitute provides higher current capacity (17.5 A vs. 15 A) and broader wire gauge compatibility (12-30 AWG vs. 12-26 AWG), offering operational flexibility. The mating angle difference (35° vs. 45°) reflects different mechanical designs but does not affect electrical performance or PCB mounting compatibility for standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796690-7 be used as a direct replacement for the Weidmüller 7940116919?

A: Yes, for applications where the 35° mating angle is mechanically compatible with the PCB layout. Both components share identical pitch (5.00mm), position count (7), voltage rating (300 V), mounting type (through-hole), and screw thread (M3). Verify that the connector orientation change does not conflict with your specific board design.

Q: What is the significance of the different mating angles?

A: The mating angle (45° vs. 35°) determines the physical orientation of the wire entry relative to the PCB surface. This affects space requirements and wire routing in the application. Ensure your PCB layout and enclosure design accommodate the substitute's 35° angle before implementation.

Q: Are there differences in wire termination that affect installation?

A: Yes. The Weidmüller uses a clamping yoke with tension sleeve, while the TE Connectivity uses a rising cage clamp. Both are screw-based termination methods. The TE Connectivity requires 0.79 Nm torque versus 0.5-0.6 Nm for the Weidmüller. Follow the manufacturer's torque specifications during installation to ensure proper wire retention.

Q: Does the higher current rating of the TE Connectivity part create compatibility issues?

A: No. A higher current rating (17.5 A vs. 15 A) indicates the substitute can handle equal or greater electrical load. This does not create incompatibility; it provides additional operational margin for your application.

Q: What compliance considerations apply to each part?

A: The TE Connectivity 796690-7 is ROHS3 compliant and REACH affected, suitable for applications requiring current environmental compliance. The Weidmüller 7940116919 is REACH unaffected and not applicable for RoHS, appropriate for applications without these regulatory requirements. Verify your application's compliance obligations before selection.

Q: Can I use the TE Connectivity part with wire gauges smaller than 12 AWG?

A: No. Both components specify a minimum wire gauge of 12 AWG. The TE Connectivity accepts up to 30 AWG (versus 26 AWG for the Weidmüller), but the lower limit remains 12 AWG for both parts.
