Weidmüller 1753420000 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1753420000 is a 3-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component belongs to the Omnimate LP series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing design support, production continuity, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1753420000 is based on strict electrical and mechanical parameter matching within the Weidmüller terminal block product family. The following parameters define substitution eligibility:

• Electrical Compatibility: Current rating (20 A), voltage rating (300 V), and wire gauge range (12-26 AWG) must be identical
• Mechanical Compatibility: Pitch (0.200" / 5.08mm), positions per level (3), mating orientation (horizontal with board), and mounting type (through hole) must match exactly
• Termination Method: Wire termination type (screw - clamping yoke, tension sleeve) must be identical
• Physical Features: Interlocking mechanism (side) and screw thread specification (M3) must be preserved
• Contact Specifications: Contact material and plating (copper alloy - tin plated) must remain consistent

The Weidmüller 1067570000 meets all substitution criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1067570000 is the direct functional substitute for the obsolete 1753420000. Selection is based on the following engineering criteria:

Product Status: The 1753420000 is classified as obsolete, making long-term sourcing and supply chain continuity problematic. The 1067570000 is an active product with confirmed inventory availability (815 pcs), ensuring reliable procurement for current and future production.

Electrical and Mechanical Equivalence: All critical electrical parameters (20 A current, 300 V voltage, 12-26 AWG wire gauge) and mechanical specifications (3 positions, 5.08mm pitch, through-hole mounting, M3 screw termination) are identical between the two parts.

Compliance and Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, confirming regulatory equivalence for export and tariff purposes.

Operating Temperature Consideration: The 1067570000 offers an extended upper operating temperature limit of 120°C compared to the 1753420000's 100°C. This represents an operational advantage with no thermal derating required for applications within the original 100°C specification.

Housing Material Difference: The 1753420000 uses polyamide (PA) nylon, while the 1067570000 uses thermoplastic wemid. Both materials are suitable for the specified electrical and thermal environment. The material change reflects manufacturing evolution within the Omnimate product family and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1067570000 be used as a direct replacement for the 1753420000 in existing designs?

A: Yes. The 1067570000 meets all electrical, mechanical, and functional requirements of the 1753420000. Pin pitch, current capacity, voltage rating, wire gauge compatibility, and screw termination specifications are identical. PCB footprints and mounting hole patterns are compatible.

Q: What is the difference between the Omnimate LP and Omnimate LL series?

A: Both series are part of the Weidmüller Omnimate terminal block family and share identical electrical and mechanical specifications for this 3-position, 5.08mm pitch configuration. The series designation reflects internal product line organization and manufacturing evolution. The LL series (1067570000) represents the current active product line.

Q: Does the housing material change from polyamide to thermoplastic wemid affect performance?

A: No. Both materials are rated for the same operating temperature range (within the specified -50°C to 100°C for the original application) and electrical environment (300 V, 20 A). The material change reflects manufacturing improvements and does not degrade electrical or mechanical performance.

Q: Are there any packaging differences between these parts?

A: The 1753420000 packaging is listed as unspecified, while the 1067570000 is supplied in bulk packaging. For production requirements, confirm bulk packaging specifications with the supplier to ensure compatibility with assembly processes.

Q: What is the operating temperature advantage of the 1067570000?

A: The 1067570000 is rated to 120°C maximum, compared to 100°C for the 1753420000. For applications operating within the original 100°C specification, this provides additional thermal margin. For applications requiring operation above 100°C, the 1067570000 extends the usable temperature range by 20°C.

Q: Are both parts RoHS and REACH compliant?

A: The 1753420000 is REACH unaffected. The 1067570000 compliance status is not specified in the provided data. Confirm current REACH and RoHS compliance status with Weidmüller for the 1067570000 before final design approval.

Q: What is the screw torque specification for installation?

A: Both parts use identical M3 screw specifications with a torque range of 0.5-0.6 Nm (4.4-5.3 Lb-In). Installation procedures and torque requirements are identical.
