Phoenix Contact 1774908 Female Insert 4 Position Screw Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1774908 is a female insert connector with 4 screw termination positions, part of the HEAVYCON® A4 series heavy duty connector line. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The connector is rated for 600V and 10A operation across an extended temperature range of -40°C to 125°C, with silver-plated copper alloy contacts housed in polyamide material meeting UL94 V-0 flammability standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1774908 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Series: HEAVYCON® A4 (ensures mechanical and electrical compatibility within the connector family)
• Connector Type: Insert (maintains form factor and mating interface)
• Gender: Female (preserves mating polarity)
• Size: D7 (ensures physical fit within existing housings)
• Termination Style: Screw (maintains installation methodology)
• Voltage Rating: 600V minimum (electrical safety requirement)
• Contact Material: Copper Alloy with Silver finish (electrical performance and corrosion resistance)
• Operating Temperature Range: -40°C to 125°C minimum (environmental compatibility)
• Material Flammability Rating: UL94 V-0 (safety compliance)

Allowable Variation Parameters:

• Number of Positions: May increase from 4 to 4+Ground (functional enhancement, backward compatible)
• Current Rating: May increase from 10A (enhanced capacity, no derating required)
• Housing Material: May vary within approved polymers (Polycarbonate acceptable as alternative to Polyamide)
• RoHS Status: May upgrade from RoHS Compliant to ROHS3 Compliant (regulatory enhancement)

The Phoenix Contact 1574908 substitute part 1585249 meets all mandatory parameters while offering enhanced current capacity (24A vs. 10A) and an additional ground position, making it a direct functional upgrade within the same connector series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1585249 is the designated substitute for the obsolete 1774908 connector insert. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The 1585249 maintains active product status within the HEAVYCON® A4 series, ensuring continued availability and manufacturer support for procurement and technical documentation.

Compliance Enhancement: The 1585249 achieves ROHS3 Compliant status compared to the RoHS Compliant rating of the original part, representing an upgrade in regulatory alignment with current environmental directives. Both parts maintain UL94 V-0 flammability certification.

Electrical Performance: The 1585249 provides increased current capacity (24A vs. 10A) while maintaining the 600V voltage rating and identical operating temperature range. This enhancement presents no compatibility issues for applications originally specified for the 1774908.

Mechanical Compatibility: Both connectors share identical D7 sizing, female gender, screw termination methodology, and HEAVYCON® A4 series designation, ensuring direct mechanical fit within existing connector housings and mating interfaces.

Functional Enhancement: The addition of a dedicated ground position in the 1585249 (4+Ground vs. 4 positions) provides improved grounding architecture without compromising backward compatibility for standard 4-position applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1585249 directly replace the 1774908 in existing assemblies?

A: Yes. Both connectors share identical D7 sizing, female gender, screw termination, and HEAVYCON® A4 series designation. The 1585249 is mechanically and electrically compatible with existing 1774908 installations.

Q: What is the significance of the additional ground position in the 1585249?

A: The 1585249 includes a dedicated ground position (4+Ground) compared to the 1774908 (4 positions). This provides enhanced grounding capability. Applications requiring only 4 signal positions can utilize the substitute without modification.

Q: Does the increased current rating of the 1585249 (24A vs. 10A) affect compatibility?

A: No. The higher current rating represents increased capacity and does not create compatibility issues. Applications originally specified for 10A operation remain fully compatible with the 24A-rated substitute.

Q: Are there differences in housing material between these connectors?

A: Yes. The 1774908 uses Polyamide (PA) nylon housing, while the 1585249 uses Polycarbonate (PC). Both materials meet UL94 V-0 flammability requirements and maintain identical operating temperature ranges (-40°C to 125°C).

Q: What is the RoHS compliance difference between these parts?

A: The 1774908 is RoHS Compliant, while the 1585249 is ROHS3 Compliant. ROHS3 represents an updated regulatory standard. Both parts meet current environmental compliance requirements.

Q: Are the contact materials and finishes identical?

A: Yes. Both connectors use copper alloy contacts with silver finish, ensuring equivalent electrical performance and corrosion resistance characteristics.

Q: What is the packaging difference between these parts?

A: The 1774908 is supplied with unspecified packaging, while the 1585249 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
