Weidmüller 944021 Terminal Block Interface Module - Equivalent & Substitute Parts

Part Overview

The Weidmüller 944021 is a 14-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 944021 carries an obsolete product status, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new installations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

No direct substitute parts are currently available in the active product database for the Weidmüller 944021. Substitution for this obsolete interface module must be evaluated based on the following critical parameters:

Primary Substitution Criteria:

• 14-position configuration
• Screw terminal connection on process side
• Rectangular male connector on control side with latching mechanism
• 16-26 AWG wire gauge compatibility
• 60VAC / 75VDC voltage rating
• 1 A per-contact current capacity
• Operating temperature range of 0°C to 55°C

When no direct equivalent exists, alternative approaches include sourcing remaining new original inventory, evaluating functionally similar interface modules from Weidmüller's current product lines with matching electrical and mechanical specifications, or considering custom terminal block assemblies that meet the specified connection and rating requirements.

Engineering Selection Recommendations

The 944021 is classified as obsolete, indicating it has been discontinued by the manufacturer. Selection of replacement components should prioritize:

1. Inventory Availability: Verify remaining new original stock through authorized Weidmüller distributors. Current inventory status shows 1149 pieces available.

2. Compliance Continuity: The part carries REACH Unaffected status, indicating no regulatory restrictions on its use or replacement. Any substitute must maintain equivalent compliance posture.

3. Functional Equivalence: Replacement components must match all specified electrical parameters (voltage, current, wire gauge) and mechanical interface requirements (screw terminals, rectangular male connector, 14-position configuration).

4. Legacy System Compatibility: For existing installations, verify mechanical fit and electrical performance before component substitution to ensure system integrity.

Frequently Asked Questions (FAQ)

Q: Why is the 944021 difficult to replace? A: The 944021 is an obsolete product, and direct equivalents may not exist in current manufacturer catalogs. Replacement requires matching specific electrical ratings (60VAC/75VDC, 1 A per contact), mechanical interfaces (screw terminals and rectangular male connector), and the 14-position configuration.

Q: Can I use a different wire gauge with a substitute part? A: No. Any substitute must support the 16-26 AWG wire gauge range specified for the 944021. Deviating from this specification may result in improper contact pressure, connection reliability issues, or safety hazards.

Q: What if I cannot find an exact substitute? A: Contact Weidmüller technical support or authorized distributors to explore custom terminal block assembly options that meet your electrical and mechanical requirements. Verify that any alternative maintains the 60VAC/75VDC rating and 1 A per-contact current capacity.

Q: Is the 944021 still compliant with current regulations? A: Yes. The part carries REACH Unaffected status, meaning it is not subject to REACH restrictions. However, verify compliance requirements for your specific application and region before deployment.

Q: What are the key parameters I must match when selecting a substitute? A: The critical parameters are: 14 positions, screw terminal process-side connection, rectangular male control-side connector with latches, 16-26 AWG wire gauge support, 60VAC/75VDC voltage rating, 1 A per-contact current, and 0°C to 55°C operating temperature range.
