Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1785740000 is determined by the following critical parameters that must remain consistent:

• Pitch: 5.08mm (0.200") - ensures PCB footprint compatibility
• Position Count: 6 positions per level - maintains electrical connection requirements
• Current and Voltage Ratings: 10A at 300V - preserves circuit protection and safety margins
• Wire Gauge Compatibility: 14-22 AWG - ensures proper wire termination without modification
• Mounting Type: Through-hole - maintains mechanical assembly compatibility
• Mating Orientation: Horizontal with board - preserves connector interface geometry
• Wire Termination Method: Screw clamp - maintains assembly and maintenance procedures
• Compliance Standards: RoHS compliance and REACH unaffected status - ensures regulatory alignment

The substitute part Weidmüller 1425850000 meets all these critical parameters, providing functional equivalence while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1425850000 is the designated substitute for the obsolete 1785740000 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status, ensuring continued availability, technical support, and manufacturing consistency. The original part's obsolete classification creates supply chain risk for new production and field service applications.

Regulatory Compliance: Both parts maintain RoHS compliance and REACH unaffected status, satisfying current environmental and safety regulations. The substitute preserves the same ECCN classification (EAR99) and HTSUS code (8536.90.4000), maintaining export and tariff consistency.

Electrical and Mechanical Equivalence: The substitute part matches all critical electrical parameters (10A, 300V), mechanical specifications (6 positions, 5.08mm pitch, through-hole mounting), and termination method (screw clamp). These parameters ensure direct PCB footprint compatibility and functional interchangeability without circuit redesign or assembly procedure modification.

Supply Chain Continuity: With 657 units in stock versus the original part's obsolete status, the substitute provides reliable component availability for both new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 1425850000 be used as a direct replacement for the 1785740000 on existing PCBs?

A: Yes. Both parts share identical pitch (5.08mm), position count (6), mounting type (through-hole), and mating orientation (horizontal with board). PCB footprints are compatible without modification.

Q: Are the electrical ratings identical between the two parts?

A: Yes. Both parts are rated for 10A at 300V with 14-22 AWG wire gauge compatibility, maintaining the same circuit protection and safety margins.

Q: What is the difference in product status, and why does it matter?

A: The original part (1785740000) is classified as obsolete, meaning it is no longer manufactured and existing inventory will eventually deplete. The substitute (1425850000) is active, ensuring continued availability, technical documentation updates, and manufacturing consistency for future orders.

Q: Are there any compliance differences between the parts?

A: No. Both parts maintain RoHS compliance, REACH unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory alignment for export and environmental requirements.

Q: What wire termination method is used in the substitute part?

A: The substitute uses screw-clamp termination (TOP clamp), identical to the original part. Assembly procedures and maintenance protocols remain unchanged.

Q: Is the substitute part available in bulk packaging?

A: Yes. The substitute part (1425850000) is available in bulk packaging with 657 units currently in stock, supporting both prototype and production-volume requirements.
