Phoenix Contact 5449571 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5449571 is a 7-position terminal block plug with female sockets, 0.150" (3.81mm) pitch, designed for 90° free-hanging in-line applications. This component operates at 8A (IEC/UL) and 320V (IEC) / 300V (UL), accommodating wire gauges from 14-30 AWG (0.2-1.5mm²). The part is currently obsolete, making substitute identification critical for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449571 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical current (8A IEC/UL) and voltage ratings (320V IEC / 300V UL)
• Mechanical Compatibility: Matching 7-position configuration, 0.150" (3.81mm) pitch, 90° plug wire entry, and free-hanging in-line mounting
• Termination Interface: Screw-based termination (including rising cage clamp variants)
• Wire Accommodation: Support for 14-30 AWG wire gauge range
• Material & Safety: Polyamide housing with UL94 V-0 flammability rating
• Regulatory Compliance: RoHS compliance status

The Phoenix Contact 1827172 meets all substitution criteria while offering enhanced wire gauge accommodation (0.14-1.5mm²) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827172 is a direct functional substitute for the obsolete 5449571. Both components share identical electrical ratings (8A/320V IEC), mechanical configuration (7-position, 3.81mm pitch, 90° entry), and safety certifications (UL94 V-0). The 1827172 offers the additional advantage of active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The rising cage clamp termination in the 1827172 provides equivalent screw-based connection reliability while supporting an extended wire gauge floor (0.14mm² minimum versus 0.2mm² for the main part).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1827172 directly replace the 5449571 in existing applications?

A: Yes. Both components maintain identical electrical specifications (8A/320V IEC), 7-position configuration, 3.81mm pitch, and 90° free-hanging mounting. The rising cage clamp termination in the 1827172 is functionally equivalent to the screw termination in the 5449571 for connection purposes.

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

A: Both are screw-based termination methods. Rising cage clamp termination provides an integrated cage mechanism that guides wire insertion and secures the connection through screw tightening, offering equivalent electrical and mechanical performance to standard screw termination.

Q: Does the 1827172 accommodate the same wire gauge range as the 5449571?

A: The 1827172 supports 14-30 AWG (0.14-1.5mm²), which encompasses the 5449571 range of 14-30 AWG (0.2-1.5mm²). The 1827172 extends compatibility to smaller wire gauges (0.14mm² minimum).

Q: What is the significance of ROHS3 compliance on the 1827172 versus RoHS compliance on the 5449571?

A: ROHS3 represents the current regulatory standard for restriction of hazardous substances in electrical and electronic equipment. The 1827172's ROHS3 compliance ensures alignment with current environmental regulations, while the 5449571's RoHS compliance reflects its obsolete status.

Q: Are there packaging differences between these components?

A: The 5449571 is listed with unspecified packaging, while the 1827172 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
