Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2281649 is determined by strict alignment of the following critical parameters:

• Positions / Poles: Must be 25 to maintain connector compatibility
• Process Side Connection: Must be Terminal Blocks - Screw Connection for wiring interface compatibility
• Control Side Connection: Must be D-Sub, Male to match the connector type
• Wire Gauge Support: Must support 12-24 AWG range
• Current Rating: Must support minimum 2.5 A per contact
• Voltage Rating: Must support 24VDC operation
• Operating Temperature Range: Must encompass -20°C ~ 50°C
• Control Side Cable Retainer: Must be Jackscrew Socket for mechanical compatibility

The Phoenix Contact 2322168 meets all critical substitution criteria, providing an active-status alternative to the obsolete 2281649 model.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2322168 is the qualified substitute for the obsolete 2281649 model. Both components maintain identical electrical and mechanical specifications across all critical parameters: 25-position configuration, screw-type terminal block connection, D-Sub male interface, 12-24 AWG wire support, 2.5 A per-contact current rating, and 24VDC voltage operation.

The 2322168 offers the advantage of active product status, ensuring continued availability and manufacturing support. The component meets ROHS3 compliance and REACH regulatory requirements, providing enhanced environmental and regulatory alignment compared to the original RoHS Compliant designation of the 2281649.

Physical dimensions differ between the two models (2281649: 90.00mm × 76.99mm; 2322168: 57.40mm × 69.01mm), requiring verification of mechanical fit within existing enclosures or panel layouts during integration.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2322168 directly replace the 2281649 in existing installations?

A: The 2322168 is electrically and functionally equivalent to the 2281649 across all critical parameters. However, physical dimensions differ, requiring confirmation that the substitute fits within the available mounting space. Electrical performance, connector compatibility, and wire gauge support are identical.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 2281649 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 2322168 maintains active status, ensuring ongoing production, technical support, and supply chain reliability for new designs and system maintenance.

Q: Are there compliance differences between the two models?

A: The 2281649 carries RoHS Compliant certification. The 2322168 meets ROHS3 Compliant and REACH Affected designations, representing enhanced environmental and regulatory compliance standards applicable to current manufacturing and distribution requirements.

Q: Do the two models support the same wire gauge and current specifications?

A: Both models support 12-24 AWG wire gauges and maintain a 2.5 A per-contact current rating at 24VDC operation. Operating temperature ranges are identical at -20°C ~ 50°C.

Q: What are the key differences between the 2281649 and 2322168?

A: The primary differences are product status (obsolete versus active), physical dimensions, series designation (VARIOFACE FLKM versus VARIOFACE VIP), and regulatory compliance levels. Electrical specifications, connector types, and functional performance remain equivalent.
