Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 1-796690-2 qualifies as a substitute based on the following shared electrical and mechanical parameters:

• Positions and Pitch: Both parts feature 12 positions per level with identical 0.197" (5.00mm) pitch spacing, ensuring PCB footprint compatibility
• Voltage Rating: Both rated at 300 V, meeting identical voltage requirements
• Mounting Type: Both are through-hole mounted components with M3 screw threads
• Housing Material: Both utilize Polyamide (PA66), Nylon 6/6 construction
• Contact Plating: Both feature tin-plated contacts for corrosion resistance

Differences exist in mating orientation (35° vs. 45°), current rating (17.5 A vs. 15 A), wire gauge acceptance (12-30 AWG vs. 12-26 AWG), and wire termination mechanism (Rising Cage Clamp vs. Clamping Yoke, Tension Sleeve). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Weidmüller 7940116924 and TE Connectivity 1-796690-2 are active production components with established supply availability. The Weidmüller part carries REACH Unaffected status, while the TE Connectivity substitute is REACH Affected. Both components are classified as EAR99 for export control purposes.

Selection between these parts depends on application-specific requirements regarding mating angle, current capacity, and wire gauge range. The TE Connectivity part provides higher current rating (17.5 A vs. 15 A) and broader wire gauge acceptance (12-30 AWG vs. 12-26 AWG), which may be advantageous in applications requiring these extended specifications. The different mating angles (35° vs. 45°) and termination mechanisms (Rising Cage Clamp vs. Clamping Yoke, Tension Sleeve) require physical verification against PCB layout and connector interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-796690-2 be used as a direct replacement for the Weidmüller 7940116924?

A: Both parts share identical pitch (5.00mm), position count (12), voltage rating (300 V), and mounting type (through-hole). However, the mating angle differs (35° vs. 45°), which affects connector interface geometry. Physical compatibility with mating connectors and PCB layout must be verified before substitution.

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

A: The Weidmüller part uses Clamping Yoke with Tension Sleeve termination, while the TE Connectivity part uses Rising Cage Clamp. These are different mechanical clamping approaches. The choice affects wire insertion force, retention characteristics, and maintenance procedures. Application requirements determine which termination method is appropriate.

Q: Are there compliance differences between these parts?

A: The Weidmüller 7940116924 is REACH Unaffected, while the TE Connectivity 1-796690-2 is REACH Affected. Both are EAR99 classified. Applications subject to REACH compliance requirements must account for this distinction.

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

A: The TE Connectivity part is rated for 17.5 A compared to 15 A for the Weidmüller part. A higher current rating does not create incompatibility; it indicates the substitute can handle equal or greater current loads. Wire gauge acceptance differs (12-30 AWG vs. 12-26 AWG), which may provide additional flexibility in wire selection.

Q: What PCB footprint considerations apply to these parts?

A: Both parts feature identical 5.00mm pitch and 12-position configuration, ensuring identical PCB hole spacing. The primary footprint difference is the mating angle (35° vs. 45°), which affects the spatial envelope above the PCB. Connector clearance and cable routing space must be verified for the specific mating angle.
