Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 1786410000 qualifies as a direct substitute based on the following critical parameters:

• Electrical Compatibility: Both parts maintain identical current (30 A) and voltage (300 V) ratings
• Mechanical Compatibility: Identical pitch (0.300"/7.62mm), position count (6), and through-hole mounting configuration
• Termination Method: Both use screw-clamp (TOP Clamp) termination with M3 screw thread and 0.5-0.6 Nm torque specification
• Series Alignment: Both belong to the TOP4GS series
• Wire Gauge Accommodation: The substitute accepts 10-26 AWG, which encompasses the original 10-22 AWG range

The substitute part is classified as active product status with enhanced operating temperature range (-50°C ~ 100°C versus -20°C ~ 100°C) and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1786410000 is the appropriate substitute for the obsolete 1751790000 based on product lifecycle status and regulatory compliance. The substitute maintains all critical electrical and mechanical parameters while offering active product status and RoHS compliance certification. The extended operating temperature range (-50°C to 100°C) provides additional environmental capability compared to the original specification (-20°C to 100°C). Both parts carry REACH Unaffected status and identical ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 1786410000 be used as a direct replacement for 1751790000 in existing designs?

A: Yes. Both parts share identical pitch, position count, current/voltage ratings, mounting configuration, and termination method. The substitute accommodates the original wire gauge range and maintains equivalent electrical performance.

Q: What is the difference in wire gauge acceptance between these parts?

A: The original 1751790000 accepts 10-22 AWG wire. The substitute 1786410000 accepts 10-26 AWG wire, providing broader wire gauge compatibility while remaining backward compatible with the original specification.

Q: Does the substitute part have different operating temperature limits?

A: The substitute operates across -50°C to 100°C, compared to the original -20°C to 100°C. This represents an extended lower temperature capability with identical upper temperature performance.

Q: Are there packaging differences between these parts?

A: The original part was supplied in unspecified packaging. The substitute is supplied in bulk packaging format.

Q: What compliance certifications apply to the substitute part?

A: The 1786410000 is RoHS compliant and carries REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: Are the screw torque specifications identical?

A: Yes. Both parts require 0.5-0.6 Nm (4.4-5.3 Lb-In) torque with M3 screw thread specification.
