Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1786690000 is determined by the following critical parameters:

• Pitch and Position Count: 0.300" (7.62mm) pitch with 12 positions per level ensures PCB footprint compatibility
• Mating Orientation and Mounting: Vertical with board orientation and through-hole mounting type maintain mechanical fit
• Electrical Ratings: Current capacity of 30 A and voltage rating of 300 V establish minimum performance requirements
• Wire Termination Method: Screw-based TOP Clamp termination ensures connection compatibility
• Screw Specification: M3 thread with 0.5-0.6 Nm torque specification maintains assembly consistency

The substitute part Weidmüller 1749170000 meets all critical substitution criteria within the TOP4GS series, maintaining identical pitch, position count, orientation, mounting type, electrical ratings, termination method, and screw specifications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1749170000 serves as a direct functional substitute for the obsolete 1786690000 within the TOP4GS terminal block series. Both components maintain identical electrical ratings, mechanical dimensions, and termination specifications required for PCB integration.

The substitute part offers the following advantages:

• Active Product Status: The 1749170000 is currently in active production, ensuring long-term availability and supply chain continuity
• Extended Temperature Range: Operating capability from -50°C to 100°C provides broader environmental tolerance compared to the -20°C to 100°C range of the main part
• RoHS Compliance: The substitute part meets RoHS requirements, supporting regulatory compliance for new designs and applications
• Expanded Wire Gauge Compatibility: Support for 10-26 AWG wire gauges provides greater flexibility than the 10-22 AWG specification of the original part

The substitute part is suitable for direct replacement in existing designs and new implementations where the TOP4GS series specification is maintained.

Frequently Asked Questions (FAQ)

Q: Can the 1749170000 be used as a direct replacement for the 1786690000 in existing PCB designs?

A: Yes. Both parts share identical pitch (0.300"/7.62mm), position count (12), mounting type (through-hole), and electrical ratings (30 A, 300 V). PCB footprints are compatible without modification.

Q: What is the significance of the wire gauge difference between the two parts?

A: The 1749170000 accommodates wire gauges from 10-26 AWG, while the 1786690000 is rated for 10-22 AWG. The substitute part's expanded range maintains compatibility with the original specification while supporting additional wire sizes.

Q: Does the extended temperature range of the 1749170000 affect its use in applications designed for the 1786690000?

A: No. The substitute part's -50°C to 100°C operating range encompasses the original part's -20°C to 100°C specification. Applications operating within the original temperature range experience no functional change.

Q: Are there packaging differences between these parts?

A: The 1786690000 is supplied in standard packaging, while the 1749170000 is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component functionality or performance.

Q: What is the significance of the contact material difference?

A: The 1786690000 uses Copper Tin Alloy plating, while the 1749170000 uses Electrolytic Copper plating. Both are tin-plated and maintain equivalent electrical performance and corrosion resistance for the specified application.

Q: Is the 1749170000 suitable for new designs?

A: Yes. The active product status and RoHS compliance of the 1749170000 make it suitable for new designs requiring the TOP4GS 12-position, 7.62mm pitch terminal block configuration.
