Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1850660000 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Weidmüller (Omnimate BU series)
• Number of Positions: 5
• Pitch: 0.400" (10.16mm)
• Mounting Type: Free Hanging (In-Line)
• Plug Wire Entry: 180°
• Termination Style: Screw - Clamping Yoke (Tension Sleeve)
• Contact Mating Finish: Silver
• Material Flammability Rating: UL94 V-0
• Contact Material: Copper Alloy
• Torque - Screw: 1.2-1.5 Nm (10.6-13.3 Lb-In)
• Wire Strip Length: 12mm
• Insulation Height: 1.205" (30.61mm)

Acceptable Variation Parameters:

• Contact Type: Blade Sockets or Female Sockets (both compatible with mating connector designs)
• Housing Material: PBT or Polyamide (PA), both glass-filled, both UL94 V-0 rated
• Current Rating: Substitute may exceed main part rating (78.3A IEC vs. 69A IEC acceptable)
• Wire Gauge Range: Substitute may support extended range (4-22 AWG vs. 6-22 AWG acceptable)
• Operating Temperature: Substitute with defined range acceptable
• Ingress Protection: Substitute with IP20 rating acceptable
• Product Status: Active status preferred over obsolete

The substitute part Weidmüller 1924740000 meets all mandatory parameters and provides enhanced specifications in current capacity and wire gauge compatibility.

Engineering Selection Recommendations

The Weidmüller 1924740000 is the direct substitute for the obsolete 1850660000 terminal block plug. Selection is based on the following engineering criteria:

Product Status: The 1924740000 maintains active product status within the Omnimate BU series, ensuring continued availability and supply chain stability compared to the obsolete 1850660000.

Electrical Compliance: Both components meet IEC and UL voltage standards (1 kV IEC / 600 V UL). The 1924740000 provides enhanced current capacity (78.3A IEC, 60A UL) compared to the main part (69A IEC, 54A UL), making it suitable for applications requiring equal or higher current handling.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and REACH Unaffected status, ensuring compliance with fire safety and environmental regulations.

Mechanical Compatibility: Identical pitch (10.16mm), mounting type (free hanging in-line), wire entry angle (180°), and termination method (screw-clamping yoke) ensure direct mechanical interchangeability with existing connector systems.

Wire Gauge Compatibility: The 1924740000 supports an extended wire gauge range (4-22 AWG) compared to the main part (6-22 AWG), providing greater flexibility for conductor sizing without compromising compatibility.

Contact Type Variation: The substitute features female sockets instead of blade sockets. This contact type difference is acceptable within the Omnimate BU series design, as both socket types are designed for compatible mating with standard connector plugs.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1924740000 directly replace the 1850660000 in existing installations?

A: Yes. Both components share identical pitch (10.16mm), mounting configuration (free hanging in-line), wire entry angle (180°), and termination method (screw-clamping yoke). The 1924740000 meets or exceeds all electrical and mechanical specifications of the 1850660000.

Q: What is the difference between blade sockets and female sockets in these terminal blocks?

A: Blade sockets and female sockets are different contact geometries within the Omnimate BU series. Both are designed for compatible mating with standard connector plugs. The contact type difference does not affect interchangeability when used with appropriate mating connectors.

Q: Does the higher current rating of the 1924740000 affect compatibility?

A: No. The 1924740000 provides enhanced current capacity (78.3A IEC vs. 69A IEC) without affecting mechanical or electrical compatibility. Higher current ratings are acceptable for direct substitution.

Q: Are there any temperature or environmental differences between these parts?

A: The 1924740000 specifies an operating temperature range of -50°C to 130°C and includes IP20 ingress protection. The 1850660000 does not specify these parameters. Both maintain UL94 V-0 flammability rating and REACH Unaffected status.

Q: What wire gauges are supported by each part?

A: The 1850660000 supports 6-22 AWG (0.2-16mm²). The 1924740000 supports 4-22 AWG (0.2-16mm²), providing compatibility with larger conductor sizes.

Q: Is the housing material difference significant?

A: Both housing materials (PBT and PA, both glass-filled) maintain UL94 V-0 flammability rating. The material difference does not affect electrical or mechanical performance for standard applications.

Q: What is the screw torque specification for installation?

A: Both components specify identical screw torque of 1.2-1.5 Nm (10.6-13.3 Lb-In). Installation procedures remain unchanged.
