Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5440761 is determined by the following critical parameters:

Electrical Compatibility: Current rating (15A minimum), voltage rating (250V minimum), and wire gauge acceptance (14-30 AWG) must be maintained or exceeded.

Mechanical Compatibility: Through-hole mounting type, 2-position configuration, and M3 screw thread specification are mandatory for direct PCB replacement.

Pitch Tolerance: The 5.00mm pitch is a primary constraint. Substitute parts with pitch values within 0.197" to 0.200" (5.00mm to 5.08mm) fall within acceptable tolerance for standard PCB hole spacing in this component class.

Mating Orientation: While the main part specifies 35° orientation, substitute parts with alternative angles (such as 55°) may be considered if PCB layout permits, provided all other electrical and mechanical parameters are satisfied.

Wire Termination: Screw-type termination with M3 thread is the baseline requirement. Rising cage clamp variants maintain functional equivalence.

Compliance Status: RoHS compliance is required for new applications; obsolete status of the main part necessitates active-status substitutes for continued supply.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1733570 qualifies as a functional substitute for the 5440761 based on the following criteria:

Electrical Equivalence: Both parts maintain identical current (15A) and wire gauge (14-30 AWG) specifications. The substitute provides enhanced voltage rating (300V vs. 250V), ensuring compatibility with applications operating at or below the original specification.

Mechanical Compatibility: Both parts feature through-hole mounting, 2-position configuration, M3 screw thread, and identical torque specifications (0.5-0.6 Nm). The pitch variance (5.00mm to 5.08mm) represents a 0.08mm difference, which is within standard PCB manufacturing tolerances for this component class.

Compliance and Availability: The substitute part carries active product status and ROHS3 compliance, addressing the obsolescence of the main part while maintaining regulatory requirements. Current inventory (20,674 units) ensures supply continuity.

Orientation Consideration: The mating orientation differs (35° vs. 55°). PCB layout verification is required to confirm that the alternative angle accommodates the intended connector interface without mechanical interference.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1733570 be used as a direct drop-in replacement for the 5440761?

A: Electrical and mechanical specifications are compatible. Verification of PCB hole spacing tolerance and connector mating angle clearance is required before implementation.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm variance falls within standard PCB manufacturing tolerances (typically ±0.1mm for through-hole spacing). This difference does not affect functional compatibility in standard applications.

Q: Does the rising cage clamp termination on the 1733570 affect wire insertion or removal procedures?

A: Rising cage clamp termination maintains screw-based wire connection methodology. Wire insertion and removal procedures remain consistent with standard screw terminal operation.

Q: Is the higher voltage rating (300V vs. 250V) of the substitute part a concern?

A: No. Higher voltage rating indicates enhanced electrical capability and does not create compatibility issues when used in applications rated at or below 250V.

Q: What compliance certifications apply to the substitute part?

A: The 1733570 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Are there inventory or lead-time advantages to using the substitute part?

A: Yes. The 1733570 maintains active product status with substantial current inventory (20,674 units), compared to the obsolete status of the 5440761, ensuring reliable supply for production requirements.
