Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5442976 is determined by the following critical parameters:

Electrical Compatibility: Current rating (15A), voltage rating (300V), and wire gauge acceptance (12-30 AWG) must remain constant across substitutes.

Mechanical Compatibility: The 3-position configuration, through-hole mounting type, and 35° board angle orientation are non-negotiable for PCB layout compatibility.

Pitch Tolerance: The pitch specification of 0.197" (5.00mm) allows for substitution with components rated at 0.200" (5.08mm) pitch, as this represents a minor dimensional variance within acceptable manufacturing tolerances for terminal block applications.

Termination Method: Screw-type wire termination is the primary requirement; rising cage clamp variants are functionally equivalent for this application.

Compliance Status: Active product status and current RoHS certification are preferred for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1713736 is the direct substitute for the obsolete 5442976. Both components maintain identical electrical specifications (15A, 300V, 12-30 AWG) and mechanical orientation (35° angle, through-hole mounting, 3-position configuration).

The 1713736 offers the following advantages for new designs and ongoing procurement:

Active Product Status: The 1713736 is currently in active production, ensuring long-term availability and supply chain stability compared to the obsolete 5442976.

Enhanced Compliance: ROHS3 certification on the 1713736 provides compliance with current regulatory requirements, whereas the 5442976 carries only RoHS Compliant status.

Pitch Variance: The 0.200" (5.08mm) pitch of the 1713736 represents a 0.03mm increase from the 5.00mm specification. This minor dimensional difference is within standard PCB design tolerances and does not affect electrical performance or mechanical fit in standard applications.

Termination Enhancement: The rising cage clamp termination on the 1713736 provides equivalent functionality to the screw termination of the 5442976, with improved wire insertion and retention characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1713736 be used as a direct replacement for the 5442976 in existing PCB designs?

A: Yes. Both components share identical electrical ratings (15A, 300V), wire gauge acceptance (12-30 AWG), mounting type (through-hole), and board orientation (35°). The pitch difference of 0.03mm (5.00mm vs. 5.08mm) is within standard PCB manufacturing tolerances and does not require design modification.

Q: What is the significance of the pitch difference between the two parts?

A: The 5442976 specifies 0.197" (5.00mm) pitch, while the 1713736 specifies 0.200" (5.08mm) pitch. This 0.03mm variance is a standard tolerance in terminal block manufacturing and does not affect PCB hole spacing or component fit in applications designed for 5mm-class terminal blocks.

Q: Are the screw specifications identical between the two parts?

A: Yes. Both components use M3 screw threads with identical torque specifications of 0.5-0.6 Nm (4.4-5.3 Lb-In). Installation procedures and torque requirements remain unchanged.

Q: What is the difference between screw termination and rising cage clamp termination?

A: Both termination methods are screw-based wire connection systems. The rising cage clamp variant on the 1713736 provides an alternative wire insertion mechanism while maintaining equivalent electrical and mechanical performance. The choice between these variants does not affect circuit functionality.

Q: Why is the 5442976 listed as obsolete?

A: Product obsolescence indicates that the 5442976 is no longer in active production. The 1713736 serves as the current production equivalent, ensuring availability for new designs and replacement applications.

Q: Are there any compliance differences between the two parts?

A: The 5442976 carries RoHS Compliant certification, while the 1713736 carries ROHS3 Compliant certification. Both meet current regulatory requirements. The ROHS3 designation on the 1713736 reflects current compliance standards for new production.
