Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1768820 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must have 9 positions with 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Termination Method: Screw-based rising cage clamp termination is required for direct substitution.
• Current & Voltage Ratings: Minimum UL ratings of 15 A at 300 V are required to maintain electrical performance specifications.
• Wire Gauge Compatibility: Acceptable wire gauge range must overlap with 12-30 AWG (0.2-2.5mm²).
• Flammability & Compliance: UL94 V-0 material rating and RoHS compliance are mandatory for equivalent substitution.
• Screw Size: M3 screw specification must be maintained for tool compatibility and torque application.

The TE Connectivity AMP Connectors part 796640-9 qualifies as a substitute based on these parameters, with the primary difference being wire entry angle (180° versus 225°).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 796640-9 is electrically and mechanically compatible with the Phoenix Contact 1768820 for applications where wire entry angle is not a constraint. Both parts maintain identical position count, pitch, current/voltage ratings, and flammability compliance.

Selection between these parts should be based on:

• Wire Entry Angle: The Phoenix Contact 1768820 features 225° wire entry, while the TE Connectivity 796640-9 provides 180° entry. Choose based on physical installation geometry and cable routing requirements.
• Torque Specification: The TE Connectivity part specifies 0.79 Nm screw torque versus 0.5-0.6 Nm for the Phoenix Contact. Ensure installation tools and procedures accommodate the specified torque value.
• Wire Gauge Range: The TE Connectivity part accepts 0.05-3mm² wire gauge, providing broader compatibility than the Phoenix Contact specification of 0.2-2.5mm².
• Product Availability: Both parts are active in production. The TE Connectivity part has 1280 units in stock versus 855 units for the Phoenix Contact.

Both parts are RoHS compliant and carry UL94 V-0 flammability ratings, meeting industrial compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796640-9 directly replace the Phoenix Contact 1768820 in existing installations?

A: Direct replacement is possible if the 180° wire entry angle accommodates the existing cable routing. The electrical and mechanical specifications are equivalent. Verify that the installation geometry permits the different wire entry orientation before substitution.

Q: What is the significance of the different wire entry angles (225° versus 180°)?

A: Wire entry angle determines the physical direction from which cables connect to the terminal block. A 225° entry allows cable approach from a specific angular position, while 180° entry provides a different approach angle. Selection depends on the physical layout of the control panel or enclosure.

Q: Are the screw torque specifications interchangeable?

A: No. The Phoenix Contact 1768820 requires 0.5-0.6 Nm torque, while the TE Connectivity 796640-9 requires 0.79 Nm. Use the torque specification provided by the manufacturer of the part being installed to ensure proper terminal connection and avoid over-tightening or under-tightening.

Q: Do both parts support the same wire gauge range?

A: Both parts accept 12-30 AWG wire. The TE Connectivity part additionally accepts 0.05-3mm² metric range, which is broader than the Phoenix Contact specification of 0.2-2.5mm². For applications using wire within the 0.2-2.5mm² range, both parts are equivalent.

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

A: Both parts are RoHS compliant, carry UL94 V-0 flammability ratings, and meet the same electrical safety standards. The TE Connectivity part additionally lists REACH compliance status. No compliance barriers exist for substitution.

Q: What is the difference between the housing materials?

A: The Phoenix Contact uses polyamide (PA) nylon, while the TE Connectivity uses polyamide (PA66) nylon 6/6. Both are polyamide-based thermoplastics with equivalent mechanical and thermal properties for this application. The difference is in the specific polyamide formulation, not in functional performance.
