Weidmüller 944020 Terminal Block Interface Module - Equivalent & Substitute Parts

Part Overview

The Weidmüller 944020 is a 10-position interface module terminal block designed for screw connection on the process side and rectangular male connector on the control side. This component facilitates signal and power distribution in industrial control applications with support for 16-26 AWG wire gauges and rated for 60VAC/75VDC operation.

The 944020 carries an obsolete product status. Locating equivalent or substitute components is necessary to maintain system compatibility in applications where this module is specified or currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 944020 requires matching the following critical parameters:

• Position Count: 10 positions
• Process Side Interface: Screw terminal connection
• Control Side Interface: Rectangular male connector with latching mechanism
• Wire Gauge Compatibility: 16-26 AWG
• Electrical Ratings: Minimum 60VAC / 75VDC support
• Current Capacity: Minimum 1 A per contact
• Operating Temperature Range: 0°C to 55°C minimum

No direct substitute parts have been identified in the current component database. Alternative solutions require evaluation of terminal block modules from other manufacturers offering equivalent 10-position screw-to-rectangular configurations with matching electrical and mechanical specifications.

No substitute parts are currently available for direct comparison.

Engineering Selection Recommendations

Given the obsolete status of the Weidmüller 944020, component selection should prioritize:

• Verification of exact connector type and pin configuration for the rectangular male interface to ensure mechanical and electrical compatibility with existing mating connectors
• Confirmation that replacement modules maintain the 10-position screw terminal configuration without requiring system redesign
• Validation that voltage and current ratings meet or exceed the 60VAC/75VDC and 1 A per contact specifications
• Assessment of operating temperature requirements within the 0°C to 55°C range

REACH compliance status should be confirmed for any replacement component to maintain regulatory alignment.

Frequently Asked Questions (FAQ)

Q: What makes a component a valid substitute for the Weidmüller 944020?

A: A valid substitute must provide 10 screw terminal positions on the process side, a rectangular male connector with latches on the control side, support 16-26 AWG wire gauges, and maintain electrical ratings of 60VAC/75VDC at 1 A per contact minimum.

Q: Why is the 944020 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: Can I use a different connector type on the control side?

A: No. The rectangular male connector with latching mechanism is a critical interface parameter. Substitutes must match this connector type to ensure compatibility with mating equipment.

Q: Are there any compliance considerations when selecting a substitute?

A: Yes. REACH compliance status should be verified for any replacement component. The original 944020 is REACH Unaffected, and replacement parts should maintain equivalent or superior compliance standing.

Q: What wire gauge flexibility exists for substitutes?

A: Substitutes must support the full 16-26 AWG range. Components supporting only narrower gauge ranges are not acceptable equivalents.
