Substitute Part Grouping Explanation

Substitution of the ED950/7 is permissible with the TE Connectivity AMP Connectors part number 796640-7 based on the following critical parameters:

Matching Parameters (Required for Substitution):

• Number of Positions: 7
• Pitch: 0.197" (5.00mm)
• Type: Plug, Female Sockets
• Plug Wire Entry: 180°
• Mounting Type: Free Hanging (In-Line)
• Current Rating (UL): 15 A
• Voltage Rating (UL): 300 V
• Material Flammability Rating: UL94 V-0
• Termination Style: Screw-based (both use screw termination)
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Allowed Parameter Variations:

• Wire Gauge Range: ED950/7 accepts 12-22 AWG; 796640-7 accepts 12-30 AWG (wider range acceptable)
• Operating Temperature: ED950/7 operates -30°C ~ 105°C; 796640-7 operates -40°C ~ 110°C (extended range acceptable)
• Contact Material: ED950/7 uses Copper; 796640-7 uses Phosphor Bronze (both acceptable for electrical performance)
• Housing Material: ED950/7 uses Polyamide (PA); 796640-7 uses Polyamide (PA66) (both acceptable)
• Screw Torque: ED950/7 requires 0.5 Nm; 796640-7 requires 0.79 Nm (within acceptable installation variance)

Parameter Comparison

Engineering Selection Recommendations

Both the ED950/7 and 796640-7 maintain active product status and full ROHS3 compliance, making either part suitable for new designs and existing applications. Selection between these parts should be based on the following engineering considerations:

ED950/7 Selection Criteria:

• Applications requiring operation within the -30°C to 105°C temperature range
• Wire gauge requirements limited to 12-22 AWG
• Designs specifying copper contact material
• Standard polyamide (PA) housing material preference

796640-7 Selection Criteria:

• Applications requiring extended temperature operation (-40°C to 110°C)
• Wire gauge flexibility up to 30 AWG for smaller conductor applications
• Phosphor bronze contact material for enhanced durability
• PA66 nylon 6/6 housing material for improved mechanical properties
• Rising cage clamp termination for enhanced wire retention
• Side stacking capability for compact multi-connector arrangements

Both parts are electrically and mechanically equivalent within their specified parameter ranges. The choice between manufacturers should consider supply chain availability, lead time, and application-specific environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the 796640-7 directly replace the ED950/7 in existing installations?

A: Yes. Both parts share identical pitch (5.00mm), position count (7), wire entry angle (180°), mounting type (free hanging in-line), current rating (15 A), voltage rating (300 V), and flammability rating (UL94 V-0). The 796640-7 features an extended operating temperature range and wider wire gauge acceptance, making it functionally compatible. Installation torque specifications differ (0.5 Nm vs. 0.79 Nm); follow the substitute part's torque requirement during installation.

Q: What is the difference between screw termination and screw rising cage clamp termination?

A: Both are screw-based termination methods. The ED950/7 uses standard screw termination. The 796640-7 uses rising cage clamp technology, which provides enhanced wire retention and simplified installation through a spring-loaded clamping mechanism activated by screw tightening. Both methods achieve equivalent electrical and mechanical performance.

Q: Are there compatibility issues with wire gauge differences?

A: The ED950/7 accepts 12-22 AWG wire. The 796640-7 accepts 12-30 AWG wire. If your application uses wire gauges between 12-22 AWG, both parts are fully compatible. If your application requires 23-30 AWG wire, only the 796640-7 is suitable.

Q: Do the different contact materials (copper vs. phosphor bronze) affect electrical performance?

A: No. Both copper and phosphor bronze contacts meet the 15 A current rating and 300 V voltage rating. Phosphor bronze offers enhanced mechanical durability and wear resistance, making it suitable for high-cycle mating applications.

Q: What packaging is available for both parts?

A: Both the ED950/7 and 796640-7 are supplied in bulk packaging. Current inventory includes 927 units for ED950/7 and 803 units for 796640-7.

Q: Are both parts RoHS compliant?

A: Yes. Both the ED950/7 and 796640-7 are ROHS3 compliant and suitable for applications requiring RoHS certification.
