Weidmüller 1751410000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1751410000 is a 5-position terminal block plug with female sockets, 0.138" (4.60mm) pitch, designed for 90° and 270° free-hanging in-line applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The Omnimate BL series plug provides IDC termination with tin-plated copper alloy contacts housed in UL94 V-0 rated polybutylene terephthalate (PBT) material.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1751410000 is determined by the following critical parameters:

Core Compatibility Requirements:

• 5-position configuration with 0.138" (4.60mm) pitch
• Female socket plug type for in-line free-hanging mounting
• Copper alloy contacts with tin plating
• UL94 V-0 flammability rating
• Operating temperature range minimum of -50°C
• RoHS compliance status

Acceptable Parameter Variations:

• Plug wire entry angle (90°/270° vs. 180°)
• Termination style (IDC vs. screw-clamping or spring-cage)
• Current rating (minimum 6A IEC or 7A UL)
• Voltage rating (minimum 250V IEC or 300V UL)
• Wire gauge range (must accommodate 20-22 AWG minimum)
• Housing material (PBT or polyamide alternatives)
• Maximum operating temperature (80°C or higher)

The two substitute parts listed below meet these core requirements while offering enhanced electrical performance and alternative termination methods.

Parameter Comparison

Engineering Selection Recommendations

1597390000 Selection Criteria: This substitute is recommended when screw-clamping termination is required. The part offers enhanced current capacity (17A IEC vs. 6A IEC) and extended operating temperature range (-50°C to 100°C). Wire gauge compatibility extends to 14-28 AWG, accommodating the original 20-22 AWG specification. The M2 screw termination with 0.2-0.25 Nm torque specification provides mechanical security. Product status is active with current manufacturing availability.

2459080000 Selection Criteria: This substitute is recommended for applications requiring screwless spring-cage termination. The part delivers the highest current rating (17.5A IEC) and maximum operating temperature range (-50°C to 120°C). Wire gauge range of 16-26 AWG encompasses the original specification. The spring-cage design eliminates screw maintenance requirements. Housing material is glass-filled polyamide, providing enhanced mechanical durability. ROHS3 compliance status indicates current regulatory alignment.

Compatibility Considerations: Both substitutes maintain the 5-position, 4.60mm pitch configuration and free-hanging in-line mounting type. The primary design difference is wire entry angle: the original part supports 90° and 270° entry, while both substitutes operate at 180°. This change requires mechanical layout evaluation in the host system. Both substitutes exceed the original electrical specifications, ensuring backward compatibility in current and voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can 1597390000 or 2459080000 directly replace 1751410000 in existing installations?

A: Direct mechanical replacement requires evaluation of wire entry angle compatibility. The original part supports 90° and 270° entry angles, while both substitutes operate at 180°. If the host system accommodates 180° wire entry, both parts are electrically and functionally compatible. The 5-position, 4.60mm pitch configuration is identical across all three parts.

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

A: The termination method differs. Part 1597390000 uses screw-clamping (M2 screw with 0.2-0.25 Nm torque), while 2459080000 uses screwless spring-cage technology. Both provide equivalent electrical performance and exceed the original part's current and voltage ratings.

Q: Are both substitutes RoHS compliant?

A: Yes. Part 1597390000 carries RoHS Compliant status, and part 2459080000 carries ROHS3 Compliant status. Both meet current regulatory requirements for hazardous substance restrictions.

Q: Which substitute supports the widest wire gauge range?

A: Part 2459080000 supports 16-26 AWG (0.14-1.5mm²), providing the broadest wire gauge compatibility. Part 1597390000 supports 14-28 AWG (0.2-1.5mm²), offering the widest range overall. Both accommodate the original specification of 20-22 AWG.

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

A: The original part operates from -50°C to 80°C. Part 1597390000 extends to 100°C, and part 2459080000 extends to 120°C. This expanded range accommodates higher-temperature applications without component replacement.

Q: Are inventory levels available for the substitute parts?

A: Part 1597390000 has 997 pcs in stock (Bulk packaging). Part 2459080000 has 932 pcs in stock (Bulk packaging). Both are actively manufactured and available for procurement.
