Weidmüller 1751160000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1751160000 is a 9-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 substitute parts necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1751160000 is determined by the following core parameters that must remain consistent:

• Connector Type & Configuration: 9-position plug with female sockets
• Pitch: 0.138" (4.60mm) spacing
• Mounting Orientation: 180° free-hanging in-line configuration
• Electrical Ratings: Minimum IEC 250V / 6A or equivalent UL ratings
• Wire Compatibility: Support for 20-22 AWG (0.35-0.5mm²) wire gauges
• Material Compliance: UL94 V-0 flammability rating, RoHS compliance
• Contact Material: Copper alloy with tin mating finish

The two substitute parts listed below maintain these core parameters while offering enhanced electrical ratings, broader wire gauge compatibility, and active product status. Termination style differences (IDC vs. screw-clamping vs. spring-cage) represent functional improvements rather than incompatibilities, as all three methods achieve equivalent electrical and mechanical connections within the specified pitch and position configuration.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with full RoHS compliance and UL94 V-0 flammability certification, providing long-term availability and regulatory compliance advantages over the obsolete 1751160000.

1606710000 offers screw-clamping termination with enhanced current capacity (17A IEC) and expanded wire gauge compatibility (14-28 AWG / 0.2-1.5mm²). This part is suitable for applications requiring higher current handling and broader wire size accommodation while maintaining the same pitch and position configuration.

2459460000 provides screwless spring-cage termination with the highest current rating (17.5A IEC) and extended operating temperature range (-50°C to 120°C). The push-button actuated design eliminates screw-based assembly, reducing installation time. Wire gauge compatibility spans 16-26 AWG (0.14-1.5mm²).

Both substitutes maintain mechanical and electrical compatibility with the original 1751160000 connector interface. Selection between them depends on termination method preference, current requirements, and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can 1606710000 or 2459460000 directly replace 1751160000 in existing assemblies?

A: Yes. Both substitutes maintain the same 9-position configuration, 0.138" (4.60mm) pitch, 180° free-hanging orientation, and female socket type. The connector interface is mechanically and electrically compatible. Termination method differences (IDC vs. screw vs. spring-cage) do not affect mating compatibility.

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

A: 1606710000 uses screw-clamping termination with M2 screws and 0.2-0.25 Nm torque specification. 2459460000 uses screwless spring-cage termination with push-button actuation. Both achieve equivalent electrical performance within the specified pitch and position framework.

Q: Are the substitute parts suitable for the same wire gauges as the original?

A: The original 1751160000 accepts 20-22 AWG (0.35-0.5mm²). Both substitutes accept broader ranges: 1606710000 supports 14-28 AWG (0.2-1.5mm²), and 2459460000 supports 16-26 AWG (0.14-1.5mm²). Both ranges encompass the original specification.

Q: What are the electrical rating differences?

A: The original part is rated 6A / 250V (IEC) and 7A / 300V (UL). Substitute 1606710000 provides 17A / 320V (IEC) and 10A / 300V (UL). Substitute 2459460000 provides 17.5A / 320V (IEC) and 10A / 300V (UL). Both substitutes exceed the original ratings, ensuring compatibility with applications designed for the 1751160000.

Q: Does housing material differ between the parts?

A: The original and 1606710000 use Polybutylene Terephthalate (PBT). The 2459460000 uses glass-filled Polyamide (PA/Nylon). Both materials meet UL94 V-0 flammability requirements and maintain equivalent mechanical performance within the connector specification.

Q: What is the operating temperature range for each part?

A: The original 1751160000 does not specify an operating temperature range. Substitute 1606710000 operates -50°C to 100°C. Substitute 2459460000 operates -50°C to 120°C. For applications requiring extended temperature performance, 2459460000 is the appropriate selection.

Q: Are all three parts RoHS compliant?

A: Yes. The original 1751160000 and both substitutes are RoHS compliant with REACH unaffected status, meeting current regulatory requirements for electronic component procurement.
