Weidmüller 1752220000 Terminal Block Equivalent & Substitute Parts

Part Overview

The Weidmüller 1752220000 is a 2-position feed-through terminal block connector designed for screw termination of conductors in the 10-22 AWG range. This component operates at 32 A (IEC) / 35 A (UL) and 800 V (IEC) / 600 V (UL), with thermoplastic Wemid insulation rated UL94 V-0. The part is classified as obsolete, making identification of equivalent active alternatives necessary for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1752220000 is determined by the following critical parameters:

• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification (32 A IEC / 35 A UL; 800 V IEC / 600 V UL)
• Mechanical Configuration: 2-position, 1-level feed-through terminal block with screw termination
• Wire Gauge Compatibility: The substitute must accommodate the conductor range required by the application
• Terminal Dimensions: Terminal width and stripping length must be compatible with existing wiring and installation practices
• Material and Certification: Thermoplastic insulation with UL94 V-0 rating ensures flame resistance compliance

The Weidmüller 1020180000 qualifies as a substitute because it maintains identical electrical ratings, mechanical configuration, termination method, and material specifications while extending wire gauge acceptance to 10-26 AWG and offering active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1020180000 is the qualified substitute for the obsolete 1752220000. Both components share identical electrical performance (32 A IEC, 800 V IEC, 35 A UL, 600 V UL) and mechanical configuration (2-position, feed-through, screw termination). The substitute maintains the same insulation material and UL94 V-0 flammability certification.

The 1020180000 offers extended wire gauge acceptance (10-26 AWG versus 10-22 AWG) and is classified as an active product with RoHS compliance, ensuring long-term availability and regulatory alignment. The terminal width difference of 0.1 mm (6.1 mm versus 6.0 mm) is within standard manufacturing tolerances and does not affect functional compatibility in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the 1020180000 directly replace the 1752220000 in existing installations?

A: Yes. Both components maintain identical electrical ratings, mechanical configuration, and termination method. The extended wire gauge range of the substitute accommodates the original specification and provides additional flexibility for future applications.

Q: What is the significance of the wire gauge range difference?

A: The 1752220000 accepts 10-22 AWG (4 mm²), while the 1020180000 accepts 10-26 AWG (0.5-6 mm²). The substitute's broader range includes the original specification and extends compatibility to smaller conductors. Applications using only 10-22 AWG conductors experience no functional change.

Q: Are there compliance differences between the two parts?

A: The 1020180000 is RoHS compliant and carries active product status, whereas the 1752220000 is obsolete with unspecified RoHS status. Both maintain UL94 V-0 flammability certification and REACH unaffected status.

Q: Does the 0.1 mm terminal width difference affect installation?

A: No. The terminal width difference (6.0 mm to 6.1 mm) is within standard manufacturing tolerances and does not impact mechanical fit or electrical performance in standard applications.

Q: What packaging is available for the substitute?

A: The 1020180000 is supplied in box packaging, with 1242 pieces available in current inventory.
