Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1648054 qualifies as a direct substitute for the 1772955 based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Connector type: Insert (female gender)
• Size designation: B24
• Termination style: Terminal Block, Straight - Screw
• Voltage rating: 600V
• Operating temperature range: -40°C to 125°C
• Housing material: Polyamide (PA), Nylon
• Contact material: Copper Alloy
• Contact finish: Silver
• Material flammability rating: UL94 V-0
• RoHS compliance: Compliant
• Moisture sensitivity level: 1 (Unlimited)

Distinguishing Characteristics: The 1648054 provides 24 positions plus one dedicated ground position, compared to the 1772955's 24 positions without dedicated ground. The 1648054 supports a higher current rating of 13A versus the 1772955's 10A. The 1648054 maintains active product status, whereas the 1772955 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1648054 is the designated substitute for the obsolete 1772955. Both components maintain identical electrical ratings (600V, operating temperature -40°C to 125°C), mechanical form factor (B24 size, terminal block screw termination), and material specifications (polyamide housing, copper alloy silver-finished contacts).

The 1648054 is actively manufactured and maintains full RoHS compliance and UL94 V-0 flammability certification. The addition of a dedicated ground position and increased current capacity (13A versus 10A) in the 1648054 provides enhanced electrical performance without compromising mechanical or thermal compatibility.

Selection of the 1648054 ensures access to current production inventory and ongoing manufacturer support, eliminating supply chain constraints associated with obsolete component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the 1648054 directly replace the 1772955 in existing assemblies?

A: Yes. Both components share identical size designation (B24), termination style (terminal block, straight screw), voltage rating (600V), and operating temperature range (-40°C to 125°C). Mechanical and electrical compatibility is maintained. The 1648054's additional ground position and higher current rating (13A) do not create incompatibility with systems designed for the 1772955.

Q: What is the significance of the dedicated ground position in the 1648054?

A: The 1648054 includes one dedicated ground position in addition to 24 signal positions, totaling 25 connection points. This provides explicit grounding capability without consuming a signal position. The 1772955 provides 24 positions without dedicated ground allocation.

Q: Are there packaging differences between these components?

A: The 1772955 packaging specification is not provided in available documentation. The 1648054 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Do both components meet the same compliance standards?

A: Yes. Both the 1772955 and 1648054 are RoHS compliant, UL94 V-0 rated, and classified as moisture sensitivity level 1 (unlimited). Both maintain REACH unaffected status.

Q: Why is the 1772955 classified as obsolete?

A: The 1772955 belongs to the HEAVYCON® KA-B series, which has been superseded by the active HEAVYCON® B24 series represented by the 1648054. Phoenix Contact has transitioned production to the newer series while maintaining electrical and mechanical compatibility.
