Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1786680000 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (30 A), voltage rating (300 V), and wire gauge acceptance range must meet or exceed the original specification
• Mechanical Compatibility: Pitch spacing (0.300"/7.62mm), number of positions (11), mounting type (through hole), and mating orientation (vertical with board) must be identical
• Termination Method: Wire termination mechanism must be screw-based TOP clamp to ensure mechanical and electrical equivalence
• Thermal Performance: Operating temperature range must encompass the original specification range

The Weidmüller 1786580000 qualifies as a substitute based on these criteria, maintaining identical electrical ratings, mechanical configuration, and termination methodology while offering extended wire gauge compatibility and improved product status.

Engineering Selection Recommendations

The Weidmüller 1786580000 is the direct functional equivalent for the obsolete 1786680000 model. Selection of the substitute part is supported by the following engineering factors:

Product Status: The 1786680000 is classified as obsolete, creating supply chain risk. The 1786580000 maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical and Mechanical Equivalence: Both parts maintain identical electrical ratings (30 A, 300 V), mechanical configuration (11 positions, 0.300" pitch, through-hole mounting), and termination methodology (screw-based TOP clamp). PCB footprint compatibility is assured.

Enhanced Specifications: The substitute part provides extended wire gauge compatibility (10-26 AWG versus 10-22 AWG) and expanded operating temperature range (-50°C to 100°C versus -20°C to 100°C), offering improved design flexibility without compromising original application requirements.

Regulatory Compliance: The 1786580000 carries RoHS compliance certification, meeting current regulatory requirements for electronic component procurement in regulated industries.

Frequently Asked Questions (FAQ)

Q: Can the 1786580000 be used as a direct replacement for the 1786680000 in existing designs?

A: Yes. Both parts share identical electrical ratings (30 A, 300 V), mechanical configuration (11 positions, 0.300" pitch), and wire termination methodology (screw-based TOP clamp). PCB footprint and mounting hole patterns are compatible. The substitute part does not require design modifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), wire gauge range (10-22 AWG versus 10-26 AWG), operating temperature range (-20°C to 100°C versus -50°C to 100°C), and RoHS compliance status. The substitute part offers extended specifications without reducing compatibility with the original application.

Q: Does the color difference between the parts affect electrical or mechanical performance?

A: No. Color is a cosmetic attribute and does not impact electrical performance, mechanical compatibility, or functional equivalence. The 1786680000 is black; the 1786580000 is orange.

Q: Are there packaging differences between these parts?

A: Yes. The 1786680000 is supplied in unspecified packaging; the 1786580000 is supplied in bulk packaging. This affects procurement and inventory management but does not impact component performance or compatibility.

Q: What is the wire gauge compatibility consideration?

A: The 1786580000 accepts wire gauges from 10-26 AWG, compared to 10-22 AWG for the 1786680000. This expanded range provides design flexibility for applications requiring smaller gauge conductors while maintaining full compatibility with the original 10-22 AWG specification.

Q: Is the substitute part suitable for applications requiring extended low-temperature operation?

A: The 1786580000 operates from -50°C to 100°C, compared to -20°C to 100°C for the 1786680000. Applications requiring operation below -20°C benefit from the substitute part's extended low-temperature rating.
