Weidmüller 7940116920 Equivalent & Substitute Parts

Part Overview

The Weidmüller 7940116920 is an 8-position wire-to-board terminal block with 45° mating orientation, 5.00mm pitch, and through-hole mounting. This component is part of the Omnimate LP series and is currently in active production status with 1092 units in stock. Terminal blocks of this specification are essential for applications requiring reliable wire-to-PCB connections with defined electrical and mechanical parameters. Substitute parts may be required due to inventory constraints, lead time considerations, or specific application requirements that align with the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Weidmüller 7940116920 are identified based on the following critical parameters that define functional compatibility:

• Position Count: 8 positions per level (fixed requirement)
• Pitch: 0.197" (5.00mm) (fixed requirement)
• Mounting Type: Through hole (fixed requirement)
• Voltage Rating: Minimum 300 V (equal or higher acceptable)
• Current Rating: Minimum 15 A (equal or higher acceptable)
• Wire Gauge Range: Must accommodate 12 AWG minimum (wider ranges acceptable)
• Screw Thread: M3 (fixed requirement)
• Housing Material: Polyamide (PA66) / Nylon 6/6 (fixed requirement)

The TE Connectivity AMP Connectors 796690-8 meets these substitution criteria with allowable variations in mating angle orientation (35° vs. 45°), wire termination method (Rising Cage Clamp vs. Clamping Yoke), and contact material composition, while maintaining electrical and mechanical compatibility within the defined parameter space.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 7940116920 and TE Connectivity 796690-8 are active production components suitable for terminal block applications requiring 8-position, 5.00mm pitch through-hole mounting. Selection between these parts should be based on the following factors:

Weidmüller 7940116920 is the primary specification component with 45° mating orientation and clamping yoke termination. This part maintains the original design intent and is recommended when the specific angle and termination method are critical to PCB layout or assembly process requirements.

TE Connectivity 796690-8 is a functionally compatible substitute with higher current rating (17.5 A vs. 15 A), wider wire gauge accommodation (12-30 AWG vs. 12-26 AWG), and significantly higher inventory availability (8995 units vs. 1092 units). The TE Connectivity part features a 35° mating angle and rising cage clamp termination. This substitute is suitable when the application can accommodate the angle variation and alternative termination method, and when inventory availability or lead time is a determining factor.

The TE Connectivity 796690-8 carries ROHS3 compliance and REACH Affected status, while the Weidmüller part is REACH Unaffected. Both components are classified under ECCN EAR99 and HTSUS 8536.90.4000.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796690-8 be used as a direct replacement for the Weidmüller 7940116920?

A: The TE Connectivity part is functionally compatible within the defined parameter space for 8-position, 5.00mm pitch terminal blocks. However, the 10° difference in mating angle (35° vs. 45°) and the different wire termination method (rising cage clamp vs. clamping yoke) require verification against specific PCB layout and assembly process requirements. Both parts maintain identical pitch, position count, voltage rating, and mounting type.

Q: What are the key differences between these two terminal blocks?

A: The primary differences are: (1) mating orientation angle (45° vs. 35°), (2) wire termination mechanism (clamping yoke with tension sleeve vs. rising cage clamp), (3) contact material base (copper alloy vs. brass), (4) current rating (15 A vs. 17.5 A), and (5) wire gauge range (12-26 AWG vs. 12-30 AWG). Both maintain identical pitch, position count, voltage rating, and through-hole mounting type.

Q: Are there any compliance or regulatory differences between these parts?

A: The Weidmüller 7940116920 is REACH Unaffected, while the TE Connectivity 796690-8 is REACH Affected and ROHS3 Compliant. Both parts are classified as EAR99 and fall under HTSUS code 8536.90.4000. Application-specific regulatory requirements should be evaluated when selecting between these components.

Q: What wire gauges can each terminal block accommodate?

A: The Weidmüller 7940116920 accommodates 12-26 AWG wire. The TE Connectivity 796690-8 accommodates 12-30 AWG wire, providing a wider range for finer gauge applications. Both parts support the same minimum wire gauge of 12 AWG.

Q: How do the screw torque specifications compare?

A: The Weidmüller 7940116920 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) screw torque. The TE Connectivity 796690-8 specifies 0.79 Nm (7.0 Lb-In) screw torque. Both use M3 screw threads. Assembly procedures should follow the respective manufacturer torque specifications.

Q: Which part should be selected for new designs?

A: Selection depends on application-specific requirements. If the 45° mating angle and clamping yoke termination are design requirements, the Weidmüller 7940116920 is the appropriate choice. If the application can accommodate the 35° angle and rising cage clamp termination, the TE Connectivity 796690-8 offers higher current rating, wider wire gauge range, and greater inventory availability.
