Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 7940116917 is determined by the following critical parameters:

• Position Count: Must be 4 positions per level
• Pitch: Must be 0.197" (5.00mm)
• Mounting Type: Must be through-hole PCB mounting
• Voltage Rating: Must be ≥300 V
• Current Rating: Must be ≥15 A
• Wire Gauge Compatibility: Must accommodate 12-26 AWG minimum
• Screw Thread: Must be M3
• Housing Material: Polyamide (PA66) or equivalent
• Mating Orientation: Angular orientation variants (35°-45°) are acceptable within mechanical envelope constraints

The TE Connectivity AMP Connectors 796690-4 meets these substitution criteria with compatible electrical ratings, identical pitch and position configuration, and equivalent mechanical mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 7940116917 and TE Connectivity 796690-4 are active production components suitable for equivalent substitution based on electrical and mechanical parameters. The TE Connectivity part provides enhanced current capacity (17.5 A vs. 15 A) and extended wire gauge accommodation (12-30 AWG vs. 12-26 AWG), offering design margin in applications with variable wire specifications.

The primary consideration for substitution is the mating orientation variance (45° vs. 35°), which requires verification against PCB layout and connector clearance specifications. The TE part's RoHS compliance status provides regulatory advantage in applications subject to RoHS requirements, whereas the Weidmüller part is marked as not applicable.

Both components utilize M3 screw threads and equivalent housing materials. The difference in wire termination mechanism (clamping yoke with tension sleeve vs. rising cage clamp) does not preclude substitution, as both employ screw-based termination with equivalent functional performance.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796690-4 directly replace the Weidmüller 7940116917 in existing designs?

A: Direct replacement is possible if PCB layout accommodates the 35° mating orientation (versus 45°). Electrical specifications are compatible. Verify connector clearance and wire routing before implementation.

Q: What is the significance of the different wire termination methods?

A: Both parts use screw-based termination. The Weidmüller employs a clamping yoke with tension sleeve; the TE part uses a rising cage clamp. Both methods provide equivalent wire retention and electrical contact. Selection depends on assembly process compatibility and operator preference.

Q: Are there wire gauge limitations when substituting?

A: The TE Connectivity part accommodates 12-30 AWG, compared to the Weidmüller's 12-26 AWG. This provides additional flexibility for finer gauge wires. Both parts support the full range of the original specification.

Q: Does the contact material difference affect electrical performance?

A: Both parts feature tin-plated contacts. The Weidmüller uses copper alloy; the TE part uses brass. Both materials provide equivalent electrical conductivity and corrosion resistance for the specified voltage and current ratings.

Q: What is the impact of the mating orientation difference?

A: The 10° orientation variance (45° vs. 35°) affects physical connector angle relative to the PCB. This requires verification of mechanical clearance in the application. Electrical performance is not affected by this geometric difference.

Q: Is RoHS compliance a factor in substitution decisions?

A: The TE Connectivity part is RoHS compliant; the Weidmüller part is marked as not applicable. If RoHS compliance is a regulatory requirement for the end application, the TE part is the appropriate selection.
