Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1407745 qualifies as a direct functional substitute for the 1773404 based on the following critical parameters:

Matching Parameters:

• Manufacturer: Phoenix Contact
• Series: HEAVYCON® HV10
• Connector Type: Insert
• Gender: Female
• Number of Positions: 10+2+Ground
• Current Rating: 16A
• Operating Temperature Range: -40°C to 125°C
• Contact Material: Copper Alloy
• Contact Finish: Silver
• Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Differentiating Parameter:

• Termination Style: The 1773404 uses screw termination, while the 1407745 uses push-in termination
• Housing Material: The 1773404 uses Polyamide (PA), Nylon; the 1407745 uses Polycarbonate (PC)
• Size Designation: The 1773404 is HV10/16; the 1407745 is B24
• Product Status: The 1773404 is obsolete; the 1407745 is active

The substitution is valid when the application can accommodate push-in termination in place of screw termination and when the housing material change from polyamide to polycarbonate is acceptable for the operating environment.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1407745 is the active production equivalent for the obsolete 1773404. Both components maintain identical electrical performance specifications including 16A current rating, identical contact materials and finishes, and equivalent temperature operating ranges. Both achieve UL94 V-0 flammability certification and unlimited moisture sensitivity classification.

The primary design consideration for substitution is the termination method transition from screw to push-in. This change simplifies assembly procedures and reduces assembly time while maintaining equivalent electrical and mechanical performance. The housing material change from polyamide to polycarbonate provides enhanced mechanical properties and environmental resistance.

The 1407745 carries active product status with current manufacturing support and ROHS3 compliance, ensuring long-term availability and regulatory alignment for new system designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the 1407745 directly replace the 1773404 in existing assemblies?

A: Substitution is possible when the connector housing and termination method can be modified to accommodate push-in termination instead of screw termination. The electrical and thermal performance characteristics are equivalent. Physical integration into the existing connector housing assembly must be verified.

Q: What is the primary difference between these two parts?

A: The 1773404 uses screw termination with polyamide housing, while the 1407745 uses push-in termination with polycarbonate housing. Both maintain identical electrical ratings, contact materials, and operating temperature ranges.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 1773404 carries RoHS Compliant status, while the 1407745 carries ROHS3 Compliant status, representing an updated compliance certification level. Both achieve UL94 V-0 flammability rating.

Q: Why is the 1773404 listed as obsolete?

A: The 1773404 has been superseded by the 1407745 in Phoenix Contact's product line. The 1407745 offers improved assembly efficiency through push-in termination while maintaining all critical electrical and thermal specifications.

Q: Are the housing materials interchangeable?

A: The housing material change from polyamide to polycarbonate represents an engineering improvement. Polycarbonate provides enhanced mechanical strength and environmental resistance. Compatibility depends on the specific application environment and mechanical stress requirements.

Q: What is the inventory status for these parts?

A: The 1773404 maintains 922 pieces in stock as new original inventory. The 1407745 maintains 1026 pieces in stock as new original inventory in bulk packaging, supporting immediate availability for production requirements.
