Weidmüller 1769320000 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 1769320000 is a 10-position wire-to-board terminal block from the Omnimate LM series, designed for horizontal PCB mounting with side entry wire connections. This component is classified as Active and remains in production. Terminal block substitution becomes necessary when inventory constraints, regional availability, or specific application requirements necessitate alternative components that maintain functional compatibility within the same electrical and mechanical parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1769320000 is determined by strict alignment with the following critical parameters:

• Pitch and Position Count: 0.200" (5.08mm) pitch with 10 positions per level
• Mating Orientation and Mounting: Horizontal with board, through-hole PCB mounting
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Wire Gauge Compatibility: Acceptable wire gauge range must accommodate the intended conductor sizes
• Termination Method: Screw-based clamping mechanism with tension sleeve
• Mechanical Interface: Side entry configuration with interlocking features
• Regulatory Compliance: RoHS compliance and REACH status alignment

The substitute part 1769160000 shares the same series designation, pitch, position count, mating orientation, mounting type, termination method, and regulatory compliance status. Differences exist in current rating, voltage tolerance, wire gauge range, operating temperature range, housing material, and contact material composition.

Parameter Comparison

Engineering Selection Recommendations

Both the 1769320000 and 1769160000 maintain Active product status within the Weidmüller Omnimate LM series and satisfy RoHS compliance requirements. Selection between these components must be based on application-specific electrical and environmental constraints:

The 1769320000 provides a 15 A current rating and extended operating temperature range (-50°C ~ 120°C), making it suitable for high-current applications and environments with extreme temperature exposure. The 1769160000 operates at 10 A with a narrower temperature range (-20°C ~ 100°C) and is appropriate for standard industrial applications within conventional thermal boundaries.

Wire gauge compatibility differs: the 1769320000 accepts 14-24 AWG conductors, while the 1769160000 accommodates 12-24 AWG. This distinction affects conductor cross-section selection and current-carrying capacity per terminal position.

Housing and contact material composition varies between the two parts. The 1769320000 uses Wemid thermoplastic with copper alloy contacts, while the 1769160000 employs polyamide (PA66) nylon housing with brass contacts. These material differences influence mechanical durability, thermal stability, and electrical conductivity characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1769160000 directly replace the 1769320000 in all applications?

A: Direct substitution is contingent upon application requirements. The 1769160000 has a lower current rating (10 A versus 15 A) and narrower operating temperature range. Substitution is valid only when circuit current demands do not exceed 10 A and operating temperatures remain within -20°C to 100°C.

Q: What are the implications of the different housing materials?

A: The 1769320000 uses Wemid thermoplastic, while the 1769160000 uses polyamide (PA66) nylon. Both materials are thermoplastic polymers suitable for PCB-mounted terminal blocks. Material selection affects mechanical rigidity, thermal performance, and chemical resistance. Application environment determines material suitability.

Q: Are the contact materials interchangeable from an electrical standpoint?

A: Both parts feature tin-plated contacts. The 1769320000 uses copper alloy base material, while the 1769160000 uses brass. Both materials provide adequate electrical conductivity for terminal block applications. Contact material selection does not preclude functional substitution when electrical ratings are satisfied.

Q: How does wire gauge range affect component selection?

A: The 1769320000 accepts 14-24 AWG wire, while the 1769160000 accepts 12-24 AWG. The 1769160000 accommodates larger conductor cross-sections (12 AWG). Selection depends on the specific wire gauges required by the application circuit.

Q: Are both parts suitable for RoHS-compliant assemblies?

A: Yes. Both the 1769320000 and 1769160000 carry RoHS Compliant designation and are suitable for RoHS-regulated applications and markets.

Q: What is the significance of the M2.5 screw thread specification?

A: Both parts use M2.5 screw threads for wire clamping. This specification ensures mechanical compatibility and consistent torque application (0.4-0.5 Nm) across both components. Screw thread standardization allows interchangeable assembly procedures.
