Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5440949 is determined by the following critical parameters:

• Position count and pitch: Both main and substitute parts must maintain 5 positions with 0.200" (5.08mm) pitch to ensure PCB footprint compatibility
• Mounting type: Through-hole mounting is required for direct board integration
• Wire termination method: Screw-based termination ensures mechanical compatibility with existing connector interfaces
• Current and voltage ratings: Substitute parts must meet or exceed 15 A and 250 V specifications
• Wire gauge accommodation: Support for 14-30 AWG wire range is mandatory
• Housing material: Polyamide (PA) nylon construction maintains thermal and mechanical properties

The Phoenix Contact 1733606 qualifies as a substitute based on these parameters. While the mating orientation differs (55° versus 35°), the fundamental electrical and mechanical characteristics align with substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1733606 is the designated substitute for the obsolete 5440949 model. Selection is based on the following engineering criteria:

Product Status: The 1733606 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 5440949.

Compliance Certifications: The 1733606 carries ROHS3 compliance, representing current regulatory alignment. Both parts maintain RoHS compliance and EAR99 export classification.

Electrical Performance: The 1733606 provides enhanced voltage rating (300 V versus 250 V), delivering superior electrical margin for applications operating at or near the 250 V specification of the original part.

Mechanical Compatibility: Identical pitch (5.08mm), position count (5), mounting type (through-hole), and wire gauge range (14-30 AWG) ensure direct PCB footprint compatibility.

Termination Enhancement: The rising cage clamp termination in the 1733606 provides improved wire retention compared to standard screw termination, while maintaining M3 screw thread compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1733606 directly replace the 5440949 on existing PCBs?

A: The 1733606 maintains identical pitch (5.08mm) and position count (5), ensuring footprint compatibility. However, the mating orientation differs (55° versus 35°), requiring verification that the connector interface accommodates the different angle. Through-hole mounting and M3 screw specifications are identical.

Q: What is the primary difference between these two terminal blocks?

A: The main differences are mating orientation (35° for 5440949 versus 55° for 1733606), voltage rating (250 V versus 300 V), wire termination method (standard screw versus rising cage clamp), and product status (obsolete versus active). Electrical current capacity and wire gauge accommodation remain identical.

Q: Does the 1733606 meet the same compliance requirements as the 5440949?

A: Both parts are RoHS compliant. The 1733606 carries ROHS3 certification, representing current regulatory standards. Both maintain EAR99 export classification and MSL 1 (unlimited) moisture sensitivity rating.

Q: Are there packaging differences between these parts?

A: The 5440949 is listed with unspecified packaging, while the 1733606 is supplied in bulk packaging. Inventory availability differs significantly (922 pcs for 5440949 versus 4023 pcs for 1733606).

Q: What wire gauges are supported by the substitute part?

A: The Phoenix Contact 1733606 accommodates 14-30 AWG wire gauges, identical to the original 5440949 specification.
