Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5437648 is based on the following critical parameters that must remain constant:

• Position Count & Pitch: 10 positions at 0.138" (4.60mm) spacing
• Connector Type: Plug with female sockets
• Wire Entry Angle: 90° orientation
• Mounting Configuration: Free hanging in-line
• Electrical Ratings: Minimum 8A at 320V (IEC) and 300V (UL)
• Wire Compatibility: Support for 14-30 AWG wire gauge range
• Housing Material: Polyamide (PA) construction with UL94 V-0 rating
• Termination Interface: Screw-based connection mechanism

The substitute part Phoenix Contact 1863233 maintains all critical parameters while offering an active product status and enhanced wire gauge compatibility (0.14-1.5mm²). The termination mechanism differs (rising cage clamp vs. standard screw), but both provide equivalent electrical and mechanical performance within the specified parameter ranges.

Engineering Selection Recommendations

The Phoenix Contact 1863233 is the direct active equivalent for the obsolete 5437648. Selection criteria are based on the following factors:

Product Status: The 5437648 is classified as obsolete. The 1863233 maintains active product status, ensuring long-term availability and continued manufacturer support.

Compliance & Certifications: Both parts maintain identical electrical ratings (8A at 320V IEC, 300V UL) and UL94 V-0 flammability certification. The 1863233 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliance of the 5437648.

Electrical & Mechanical Compatibility: Both components share identical pitch (4.60mm), position count (10), wire entry angle (90°), mounting configuration (free hanging in-line), and housing material (Polyamide PA). Screw torque specifications overlap within acceptable ranges (0.22-0.25 Nm for 1863233 vs. 0.2-0.25 Nm for 5437648).

Wire Gauge Compatibility: The 1863233 supports an extended minimum wire gauge of 0.14mm² compared to 0.2mm² for the 5437648, providing broader compatibility with finer conductor applications while maintaining the 1.5mm² maximum.

Termination Mechanism: The 1863233 employs a rising cage clamp termination versus standard screw termination on the 5437648. Both mechanisms provide equivalent electrical connection performance within the specified current and voltage parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1863233 directly replace the 5437648 in existing applications?

A: Yes. Both components maintain identical electrical ratings (8A at 320V IEC), pitch spacing (4.60mm), position count (10), and mounting configuration (90° free hanging in-line). The housing material, flammability rating, and wire gauge compatibility are equivalent. The primary difference is the termination mechanism (rising cage clamp vs. standard screw), which does not affect electrical or mechanical compatibility.

Q: What is the significance of the product status difference between these parts?

A: The 5437648 is classified as obsolete, indicating Phoenix Contact no longer manufactures or supports this component. The 1863233 is active, ensuring continued availability, manufacturer technical support, and compliance with current regulatory standards. For new designs or ongoing procurement, the active 1863233 is the appropriate selection.

Q: Are there wire gauge compatibility differences between these parts?

A: The 1863233 supports a minimum wire gauge of 0.14mm² compared to 0.2mm² for the 5437648. Both support a maximum of 1.5mm². This means the 1863233 accommodates finer conductors. For applications using wire gauges between 0.14-0.2mm², only the 1863233 is suitable. For wire gauges 0.2-1.5mm², both parts are compatible.

Q: How do the termination styles differ, and does this affect selection?

A: The 5437648 uses standard screw termination, while the 1863233 uses screw-based rising cage clamp termination. Both mechanisms provide equivalent electrical connection performance within the specified current and voltage ratings. The rising cage clamp design in the 1863233 may offer improved wire retention characteristics, but both are functionally equivalent for the stated electrical parameters.

Q: What compliance certifications should I verify for my application?

A: Both parts carry UL94 V-0 flammability certification and EAR99 export classification. The 1863233 carries ROHS3 compliance, while the 5437648 carries RoHS compliance. Verify that your application requirements align with these certifications. The 1863233 represents current regulatory alignment for new applications.

Q: Is the packaging format a consideration when selecting between these parts?

A: The 5437648 is listed with unspecified packaging, while the 1863233 is supplied in bulk packaging. Confirm packaging requirements with your procurement process. Both parts maintain identical MSL rating (1 - Unlimited), indicating no special moisture handling is required during storage or transport.
