Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 1751100000 is determined by the following critical parameters:

Core Compatibility Requirements:

• Identical pitch: 0.138" (4.60mm)
• Identical number of positions: 3
• Identical plug orientation: 180° free-hanging in-line
• Identical connector type: Plug with female sockets
• Identical series: Omnimate BL
• Identical color: Orange
• Identical contact material: Copper alloy with tin mating finish
• Identical housing material: Polybutylene Terephthalate (PBT)
• Identical flammability rating: UL94 V-0
• Identical mating flange feature

Allowable Variations: Substitute parts may differ in termination style (IDC vs. screw-clamping vs. screwless spring cage), wire gauge range, current/voltage ratings, operating temperature range, and ingress protection rating, provided the core compatibility requirements are met.

Parameter Comparison

Engineering Selection Recommendations

1606650000 (Screw-Clamping Termination)

This substitute maintains identical mechanical and electrical compatibility with the 1751100000 while offering enhanced current and voltage ratings (17A IEC, 320V IEC vs. 6A IEC, 250V IEC). The screw-clamping termination provides secure wire retention with defined torque specifications (0.2-0.25 Nm). The expanded wire gauge range (14-28 AWG / 0.2-1.5mm²) accommodates broader conductor sizes. Operating temperature range of -50°C to 100°C supports standard industrial applications. Active product status ensures ongoing availability and supply chain continuity.

2459400000 (Screwless Spring Cage Termination)

This substitute provides the highest current rating (17.5A IEC, 320V IEC) and extended operating temperature range (-50°C to 120°C). The screwless spring cage termination eliminates screw torque requirements and includes push-button actuation for tool-free wire insertion and removal. Wire gauge range of 16-26 AWG (0.14-1.5mm²) covers most standard applications. Housing material differs (polyamide with glass fill vs. PBT), maintaining UL94 V-0 flammability compliance. Active product status ensures availability. This option is suitable for applications requiring simplified installation and higher temperature tolerance.

Both substitutes are RoHS compliant and maintain the Omnimate BL series designation, ensuring mechanical and electrical interchangeability with the obsolete 1751100000 in equivalent connector systems.

Frequently Asked Questions (FAQ)

Q: Can 1606650000 or 2459400000 directly replace 1751100000 in existing installations?

A: Yes. Both substitutes maintain identical pitch (4.60mm), position count (3), wire entry angle (180°), mounting type (free-hanging in-line), connector type (plug with female sockets), and series designation (Omnimate BL). Mechanical and electrical interchangeability is confirmed. Termination style differs (screw-clamping or screwless vs. IDC), requiring appropriate wire preparation methods for each substitute.

Q: What are the key differences between the two substitutes?

A: 1606650000 uses screw-clamping termination with defined torque specifications (0.2-0.25 Nm) and operates to 100°C. 2459400000 uses screwless spring cage termination with push-button actuation and operates to 120°C. Both offer higher current ratings than the original part (17A and 17.5A IEC respectively vs. 6A IEC).

Q: Are there wire gauge compatibility considerations?

A: The original 1751100000 accepts 20-22 AWG (0.35-0.5mm²). Substitute 1606650000 accepts 14-28 AWG (0.2-1.5mm²), and 2459400000 accepts 16-26 AWG (0.14-1.5mm²). Both substitutes accommodate the original wire gauge range, ensuring backward compatibility. Verify wire gauge selection matches the specific application requirements.

Q: Do the substitutes maintain the same packaging and inventory status?

A: The original 1751100000 is obsolete with 857 units in stock. Substitute 1606650000 is active with 1128 units in stock (bulk packaging). Substitute 2459400000 is active with 803 units in stock (bulk packaging). Active status ensures long-term availability for new designs and ongoing maintenance.

Q: Are there housing material differences that affect application suitability?

A: The original 1751100000 and substitute 1606650000 use polybutylene terephthalate (PBT) housing. Substitute 2459400000 uses polyamide (PA) nylon with glass fill. Both materials maintain UL94 V-0 flammability compliance. Material selection may influence chemical resistance and mechanical properties in specific environmental conditions.

Q: What is the significance of the IP20 ingress protection rating on the substitutes?

A: The original 1751100000 does not specify an ingress protection rating. Both substitutes provide IP20 protection, indicating resistance to solid objects larger than 12mm and liquid splash from any direction. This enhancement provides additional environmental protection in industrial applications.
