Phoenix Contact 1620443 Circular Connector Receptacle Housing

Part Overview

The Phoenix Contact 1620443 is a 4-position (3 + PE) circular connector receptacle housing designed for panel mount, right-angle applications. This connector features a rotatable backshell, metal construction with silver finish, and IP67 ingress protection rating. The part operates across a temperature range of -40°C to 125°C and is ROHS3 compliant.

The 1620443 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility, ensure continued availability, and support ongoing procurement for applications currently utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1620443 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle Housing
• Number of Positions: 4 (3 + PE)
• Shell Size - Insert: M17-4
• Mounting Type: Panel Mount, Right Angle
• Mounting Feature: Flange
• Contact Type: Crimp
• Ingress Protection: IP67 minimum

Compatible Variation Parameters:

• Series designation (ST to PRO transition acceptable for active product lines)
• Fastening Type (Push-Twist to Threaded acceptable with mechanical compatibility verification)
• Shielding (Shielded to Unshielded acceptable if application does not require EMI protection)
• Operating Temperature range (provided minimum operating temperature does not fall below application requirement)

The Phoenix Contact 1628519 meets all mandatory matching parameters and represents the manufacturer-recommended substitute from the active PRO series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1628519 is the manufacturer-recommended substitute for the obsolete 1620443. Both connectors share identical mechanical and electrical interface specifications: M17-4 shell size, 4-position configuration, panel mount right-angle orientation, and flange mounting feature.

The 1628519 is classified as an active product, ensuring long-term availability and continued manufacturing support. The substitute maintains ROHS3 compliance through the Phoenix Contact product line standards.

Key differences requiring evaluation:

Fastening Type: The 1620443 uses Push-Twist fastening, while the 1628519 uses Threaded fastening. This represents a mechanical interface change that must be verified against mating connector specifications and installation procedures.

Shielding: The 1620443 is shielded; the 1628519 is unshielded. Applications requiring electromagnetic interference protection must confirm that unshielded operation is acceptable or source an alternative shielded variant.

Operating Temperature: The 1620443 operates to 125°C; the 1628519 operates to 105°C. Applications requiring operation above 105°C must source an alternative part.

Ingress Protection: The 1628519 provides IP67/IP68 protection, exceeding the 1620443 IP67 specification.

Frequently Asked Questions (FAQ)

Q: Can the 1628519 directly replace the 1620443 in existing installations?

A: Mechanical and electrical interface compatibility is confirmed for the M17-4 shell size and 4-position configuration. However, fastening type differs (Push-Twist to Threaded), requiring verification that mating connectors and installation procedures accommodate threaded fastening. Shielding differences must also be evaluated against application EMI requirements.

Q: What is the significance of the fastening type change from Push-Twist to Threaded?

A: Fastening type affects connector mating and unmating procedures. Push-Twist fastening uses rotational locking; Threaded fastening uses screw-based locking. The mating connector must be compatible with the threaded fastening mechanism. Installation and maintenance procedures may require modification.

Q: Does the unshielded design of the 1628519 affect performance compared to the shielded 1620443?

A: Shielding provides electromagnetic interference (EMI) protection. Applications operating in electromagnetically noisy environments or requiring EMI suppression must confirm that unshielded operation is acceptable. If shielding is required, alternative shielded connectors must be sourced.

Q: Are there temperature limitations when substituting the 1628519 for the 1620443?

A: The 1628519 operates to 105°C maximum, compared to the 1620443 at 125°C. Applications requiring sustained operation above 105°C cannot use the 1628519 and must source an alternative part rated for higher temperatures.

Q: What packaging is available for the 1628519?

A: The 1628519 is supplied in Bulk packaging. Verify that bulk packaging meets procurement and inventory management requirements.

Q: Is the 1628519 RoHS compliant?

A: RoHS compliance status for the 1628519 is not specified in the available technical data. Confirm RoHS compliance requirements with Phoenix Contact technical documentation or sales support if regulatory compliance is mandatory for your application.
