Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 2315010

The Phoenix Contact 2315010 is the identified equivalent for the obsolete Weidmüller 915911 based on functional architecture and electrical compatibility. Selection of this substitute is appropriate when the following conditions are met:

Application voltage requirement does not exceed 60V
Wire gauge requirement falls within 12-24 AWG range
Operating temperature minimum requirement is -20°C or higher
Mechanical envelope allows for dimensional variations (length: 34.70mm vs. 39.88mm; width: 65.50mm vs. 70.00mm)
Rectangular male connector interface is compatible with existing control-side harnesses

The Phoenix Contact 2315010 carries active product status with current manufacturing support and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2315010 directly replace the Weidmüller 915911 in all applications?

A: Direct replacement is possible only when application parameters fall within the 2315010 specifications. The substitute has lower voltage rating (60V vs. 125V), narrower wire gauge support (12-24 AWG vs. 12-26 AWG), and slightly higher minimum operating temperature (-20°C vs. -25°C). Verify your application requirements against these parameters before substitution.

Q: What are the dimensional differences between these parts?

A: The Phoenix Contact 2315010 is physically smaller: 34.70mm length and 65.50mm width compared to the Weidmüller 915911 at 39.88mm length and 70.00mm width. Confirm that your mechanical mounting and panel layout accommodate these dimensional variations.

Q: Are both parts RoHS compliant?

A: Yes. The Weidmüller 915911 is RoHS Compliant, and the Phoenix Contact 2315010 is ROHS3 Compliant. Both meet environmental regulatory requirements for their respective manufacturing periods.

Q: What is the wire gauge compatibility consideration?

A: The Weidmüller 915911 accepts 12-26 AWG wire, while the Phoenix Contact 2315010 accepts 12-24 AWG wire. If your application uses 25 or 26 AWG wire, the 2315010 cannot accommodate these gauges. Verify your actual wire gauge requirements before substitution.

Q: Why is the Weidmüller 915911 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Phoenix Contact 2315010 is an active product with ongoing manufacturing support, making it suitable for new designs and system replacements requiring long-term component availability.

Q: Are there any voltage derating considerations?

A: The Phoenix Contact 2315010 has a rated voltage of 60V compared to the Weidmüller 915911 at 125V. Applications operating above 60V cannot use the 2315010 as a substitute. Confirm your system voltage before selection.
