Weidmüller 1751180000 Terminal Block Plug Equivalent & Substitute Parts

Part Overview

The Weidmüller 1751180000 is an 11-position terminal block plug with female sockets, 0.138" (4.60mm) pitch, designed for 180° free-hanging in-line applications. This component features IDC termination and is part of the Omnimate BL series. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1751180000 is based on the following critical parameters that must remain compatible:

• Connector Type & Configuration: 11-position plug with female sockets
• Pitch & Spacing: 0.138" (4.60mm) pitch for mechanical compatibility
• Wire Entry Orientation: 180° free-hanging in-line mounting
• Electrical Performance: Voltage and current ratings must meet or exceed IEC/UL specifications
• Wire Gauge Compatibility: Acceptable wire gauge ranges for termination
• Compliance & Certifications: RoHS compliance and material flammability ratings

The substitute parts identified (1606730000 and 2459480000) maintain the core mechanical interface (11 positions, 4.60mm pitch, 180° orientation) while offering enhanced electrical performance and active product status. Both substitutes are manufactured by Weidmüller within the Omnimate BL series, ensuring design continuity.

Parameter Comparison

Engineering Selection Recommendations

1606730000 (Screw Termination Variant)

This substitute maintains the same housing material (PBT) as the original 1751180000 while upgrading to screw-clamping termination. It provides enhanced electrical performance (17A IEC, 320V IEC) and expanded wire gauge compatibility (14-28 AWG, 0.2-1.5mm²). The part is active and RoHS compliant. Selection of this variant is appropriate when screw-based termination is preferred and the wider wire gauge range is beneficial for system flexibility.

2459480000 (Screwless Spring Cage Variant)

This substitute offers the highest electrical performance (17.5A IEC, 320V IEC) with screwless spring cage termination, eliminating torque specification requirements. It features an extended operating temperature range (-50°C to 120°C) and push-button actuation. The housing material differs (glass-filled polyamide instead of PBT). This variant is active and RoHS compliant. Selection is appropriate for applications requiring tool-free termination and higher temperature operation.

Both substitutes are manufactured by Weidmüller, maintain the Omnimate BL series designation, and preserve the critical mechanical interface (11 positions, 4.60mm pitch, 180° orientation) required for compatibility with existing mating connectors.

Frequently Asked Questions (FAQ)

Q: Can 1606730000 or 2459480000 directly replace 1751180000 in existing systems?

A: Mechanical compatibility is maintained (11 positions, 4.60mm pitch, 180° orientation). However, termination method differs: the original uses IDC, while 1606730000 uses screw clamping and 2459480000 uses spring cage. Existing wire terminations must be re-terminated using the appropriate method for the selected substitute.

Q: What is the primary difference between the two substitute parts?

A: 1606730000 uses screw-clamping termination with M2 screws (0.2-0.25 Nm torque), while 2459480000 uses screwless spring cage termination with push-button actuation. 2459480000 also offers higher current capacity (17.5A vs 17A IEC) and extended temperature range (-50°C to 120°C vs -50°C to 100°C).

Q: Are the substitute parts RoHS compliant?

A: Yes, both 1606730000 and 2459480000 are RoHS compliant, matching the compliance status of the original 1751180000.

Q: What wire gauges are compatible with each substitute?

A: 1606730000 accepts 14-28 AWG (0.2-1.5mm²), while 2459480000 accepts 16-26 AWG (0.14-1.5mm²). The original 1751180000 was limited to 20-22 AWG (0.35-0.5mm²), so both substitutes provide expanded wire gauge flexibility.

Q: Does housing material affect electrical performance?

A: Both housing materials (PBT in 1606730000 and glass-filled polyamide in 2459480000) meet UL94 V-0 flammability requirements. Material selection should be based on operating temperature requirements and mechanical environment. 2459480000's glass-filled polyamide supports the extended temperature range (-50°C to 120°C).

Q: What is the inventory status of these substitutes?

A: 1606730000 has 796 pieces in stock, and 2459480000 has 1015 pieces in stock, both available as new original components.
