Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5452591 is determined by strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 6
• Pitch spacing: 0.138" (4.60mm)
• Plug wire entry orientation: 270°
• Mounting configuration: Free Hanging (In-Line)
• Type: Plug with female sockets
• Screw termination capability
• M2 screw size

Electrical Compatibility Parameters:

• Current rating: minimum 8A (IEC and UL)
• Voltage rating: minimum 160V (IEC) and 300V (UL)
• Wire gauge support: 14-30 AWG minimum range

Physical Compatibility Parameters:

• Insulation height: 0.752" (19.10mm)
• Contact mating finish: Tin

The substitute part Phoenix Contact 1862894 meets all core compatibility parameters. Differences exist in termination mechanism (Rising Cage Clamp vs. standard screw), voltage rating (320V IEC vs. 160V IEC), wire gauge lower limit (0.14mm² vs. 0.2mm²), housing material specification, and product status (Active vs. Obsolete). These differences do not prevent functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1862894

The 1862894 is the qualified substitute for the obsolete 5452591. Both components share identical mechanical pitch, position count, wire entry orientation, and mounting configuration. Electrical ratings are compatible, with the 1862894 providing equal or superior performance (320V IEC vs. 160V IEC). The 1862894 maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The termination mechanism difference (Rising Cage Clamp vs. standard screw) represents an engineering enhancement rather than a limitation. The Rising Cage Clamp termination provides equivalent electrical connection with improved wire retention characteristics. Wire gauge support is expanded in the 1862894 (0.14mm² minimum vs. 0.2mm² minimum), providing greater flexibility for smaller conductor applications.

Both components are rated MSL 1 (Unlimited) and maintain identical insulation height and contact finish specifications, ensuring direct mechanical and electrical compatibility in existing connector housings and mating interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 1862894 directly replace the 5452591 in existing assemblies?

A: Yes. Both components share identical pitch (4.60mm), position count (6), wire entry angle (270°), mounting type (free-hanging in-line), and insulation height (19.10mm). Mechanical compatibility is confirmed. Electrical ratings of the 1862894 meet or exceed the 5452591 specifications.

Q: What is the significance of the Rising Cage Clamp termination in the 1862894?

A: The Rising Cage Clamp is a termination mechanism that provides secure wire retention through a spring-loaded cage design. It maintains electrical continuity equivalent to screw termination while offering improved wire strain relief. Both termination methods are compatible with the same wire gauge range (14-30 AWG).

Q: Are there packaging differences between these parts?

A: The 5452591 is supplied in unspecified packaging, while the 1862894 is supplied in bulk packaging. This difference affects procurement and handling but does not impact component performance or compatibility.

Q: Does the voltage rating difference affect substitution suitability?

A: No. The 1862894 operates at 320V (IEC) compared to the 5452591 at 160V (IEC). The higher rating in the substitute part represents improved performance margin and does not create incompatibility. Both meet the 300V UL requirement identically.

Q: What is the impact of the wire gauge range expansion in the 1862894?

A: The 1862894 supports wire gauges down to 0.14mm² (vs. 0.2mm² minimum in the 5452591). This expansion allows use with smaller conductors without affecting compatibility with the original 0.2-1.5mm² range. The upper limit remains identical at 1.5mm².

Q: Are both components RoHS compliant?

A: Yes. The 5452591 is RoHS Compliant, and the 1862894 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.
