Weidmüller 915914 Interface Module Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 915914 is a 20-position interface module terminal block featuring screw connection on the process side and rectangular male connector on the control side. This component is classified as obsolete, making identification of equivalent substitute parts essential for system maintenance and component procurement. The part operates at 125V rated voltage with 1A per-contact current rating and supports wire gauges from 12-26 AWG.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 915914 is determined by the following critical parameters:

• Positions / Poles: Must equal 20
• Process Side Connection: Must be Terminal Blocks - Screw Connection
• Control Side Connection: Must be Rectangular, Male
• Control Side Cable Retainer: Must include Latches
• Current Rating (Per Contact): Must be ≥ 1 A
• Wire Gauge Compatibility: Must support the required wire gauge range

The Phoenix Contact 2315049 qualifies as a substitute based on matching these core functional parameters. However, differences exist in voltage rating, operating temperature range, and physical dimensions that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2315049 serves as an active substitute for the obsolete Weidmüller 915914. Both components maintain identical functional architecture with 20 positions, screw-connection process side, rectangular male control side, and 1A per-contact current rating.

Selection between these parts depends on application voltage requirements. The Weidmüller 915914 operates at 125V rated voltage, while the Phoenix Contact 2315049 is rated for 60V. Applications requiring the full 125V rating cannot use the Phoenix Contact substitute without circuit redesign.

The Phoenix Contact 2315049 supports wire gauges 12-24 AWG, which is compatible with the majority of the Weidmüller part's 12-26 AWG range. Applications requiring 25-26 AWG wire connections are not compatible with the Phoenix Contact substitute.

Physical dimensions differ between the two parts. The Phoenix Contact 2315049 is smaller in both length and width, which may affect mechanical fit in existing enclosures or mounting configurations designed for the Weidmüller 915914.

Both components are RoHS compliant and REACH unaffected, meeting current regulatory compliance standards. The Phoenix Contact 2315049 carries active product status, ensuring ongoing availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2315049 directly replace the Weidmüller 915914 in all applications?

A: Direct replacement is possible only when application voltage does not exceed 60V and wire gauges remain within the 12-24 AWG range. Applications requiring 125V operation or 25-26 AWG wire support require the original Weidmüller part or alternative sourcing.

Q: What are the physical compatibility considerations?

A: The Phoenix Contact 2315049 has smaller physical dimensions (2.169" × 2.579") compared to the Weidmüller 915914 (2.550" × 2.756"). Verify that mounting locations, enclosure cutouts, and adjacent component spacing accommodate the smaller footprint before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The Weidmüller 915914 is RoHS Compliant, and the Phoenix Contact 2315049 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the minimum operating temperature difference between these parts?

A: The Weidmüller 915914 operates from -25°C, while the Phoenix Contact 2315049 operates from -20°C. Applications requiring operation below -20°C require the original Weidmüller part.

Q: Are connector compatibility and latching mechanisms identical?

A: Both parts feature rectangular male control-side connectors with latches. Mechanical and electrical compatibility is confirmed for the connector interface.
