Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1771011 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Insert
• Gender: Female
• Number of Positions: 6
• Size: B6
• Series: HEAVYCON® B6
• Termination Style: Screw
• Voltage Rating: 600V
• Operating Temperature Range: -40°C to 125°C
• Contact Material: Copper Alloy
• Contact Finish: Silver
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current Rating: May increase from 15A (substitute rated at 16A is acceptable)
• Housing Material: May vary within equivalent material classes (Polyamide to Polycarbonate, both glass-filled variants)
• RoHS Status: May upgrade from RoHS Compliant to ROHS3 Compliant
• Product Status: Active status preferred over obsolete

The substitute part 1648128 meets all mandatory matching criteria and demonstrates allowable variations in current rating and housing material composition.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1648128 is the direct substitute for the obsolete 1771011. Both components maintain identical electrical and mechanical specifications across all critical parameters within the HEAVYCON® B6 series framework.

The 1648128 demonstrates superior product lifecycle status as an active component, ensuring long-term availability and supply chain continuity. The increased current rating of 16A provides additional operational margin compared to the 15A specification of the original part. The housing material upgrade from polyamide to glass-filled polycarbonate maintains UL94 V-0 flammability compliance while offering enhanced mechanical durability.

Both components satisfy RoHS compliance requirements, with the substitute meeting the more stringent ROHS3 standard. Screw termination compatibility and identical connector geometry ensure direct mechanical and electrical interchangeability within existing HEAVYCON® B6 assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 1648128 directly replace the 1771011 in existing applications?

A: Yes. Both components share identical connector type, gender, position count, size designation, termination style, voltage rating, and operating temperature range. The 1648128 meets or exceeds all electrical and mechanical requirements of the 1771011.

Q: What is the significance of the current rating difference between 15A and 16A?

A: The 1648128 current rating of 16A exceeds the 1771011 specification of 15A. This represents an allowable variation that does not compromise substitution eligibility. Applications designed for 15A operation remain fully compatible with the higher-rated substitute.

Q: How do the housing materials differ between these parts?

A: The 1771011 uses polyamide (PA) nylon housing, while the 1648128 uses glass-filled polycarbonate (PC). Both materials maintain UL94 V-0 flammability certification. The polycarbonate variant offers improved mechanical durability and environmental resistance.

Q: What does ROHS3 compliance mean compared to RoHS Compliant?

A: ROHS3 represents compliance with the most current Restriction of Hazardous Substances directive iteration. The 1648128 meets this enhanced standard, ensuring alignment with current regulatory requirements. The 1771011 meets the baseline RoHS standard.

Q: Is the 1648128 available in the same packaging as the 1771011?

A: The 1648128 is supplied in bulk packaging. Packaging configuration should be verified against specific procurement requirements for your application.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both the 1771011 and 1648128 operate across the identical -40°C to 125°C temperature range with no thermal performance differentiation.
