Weidmüller 1753840000 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 1753840000 is a 3-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for vertical through-hole mounting on PCBs. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates at 15 A and 300 V with screw-clamping wire termination, serving applications requiring reliable electrical connections in industrial control and automation systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1753840000 is determined by strict alignment with the following core parameters:

• Pitch and Position Count: Must maintain 0.200" (5.08mm) pitch with 3 positions per level to ensure PCB footprint compatibility
• Mating Orientation: Must be vertical with board configuration for through-hole mounting
• Electrical Ratings: Current and voltage ratings must meet or exceed 15 A and 300 V respectively
• Wire Termination Method: Screw-based clamping is required for mechanical compatibility
• Mounting Configuration: Through-hole mounting on PCB is mandatory
• Regulatory Compliance: RoHS compliance is required for modern supply chains

Two substitute parts meet these criteria:

Weidmüller 1716050000 (Omnimate LM series): Active product with identical pitch, position count, and mounting orientation. Operates at the same electrical ratings with improved temperature range (-50°C to 120°C versus -20°C to 100°C). Wire gauge acceptance is narrower (14-24 AWG versus 12-26 AWG). Screw specification differs (M2.5 versus M3), requiring torque adjustment (0.4-0.5 Nm versus 0.5-0.6 Nm).

TE Connectivity 1546073-3 (Buchanan series): Active product with identical pitch, position count, and mounting orientation. Exceeds electrical ratings (17.5 A current, same 300 V voltage). Accepts wider wire gauge range (12-30 AWG). Uses M3 screw thread matching the original. Wire termination method differs (Rising Cage Clamp versus Clamping Yoke, Tension Sleeve), representing a functional alternative within the screw-clamping category.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with minimal design modification: Select Weidmüller 1716050000. This part maintains the same manufacturer ecosystem, identical electrical ratings, and matching wire termination principle. The narrower wire gauge acceptance (14-24 AWG) requires verification against existing wire specifications. The M2.5 screw thread necessitates torque adjustment from 0.5-0.6 Nm to 0.4-0.5 Nm. Both parts are RoHS compliant and REACH unaffected, ensuring regulatory continuity.

For applications requiring enhanced electrical performance: Select TE Connectivity 1546073-3. This part provides higher current capacity (17.5 A versus 15 A), wider wire gauge acceptance (12-30 AWG), and improved temperature range (-40°C to 105°C). The M3 screw thread matches the original specification. The Rising Cage Clamp termination method differs from the original Clamping Yoke design but operates within the screw-clamping category. ROHS3 compliance and REACH affected status require supply chain verification for regulated applications.

For new designs: Either substitute part is acceptable. The choice depends on wire gauge requirements, temperature operating range, and supply chain compliance obligations.

Frequently Asked Questions (FAQ)

Q: Can the 1716050000 directly replace the 1753840000 without PCB modification?

A: Yes, regarding footprint. The 0.200" (5.08mm) pitch and 3-position configuration are identical, ensuring through-hole mounting compatibility. However, the M2.5 screw thread differs from the original M3, requiring torque specification adjustment in assembly documentation. Wire gauge acceptance is narrower (14-24 AWG versus 12-26 AWG), so verify existing wire specifications.

Q: What is the functional difference between Clamping Yoke and Rising Cage Clamp termination methods?

A: Both are screw-based clamping mechanisms. The Clamping Yoke uses a tension sleeve for wire retention, while the Rising Cage Clamp uses a cage mechanism that rises as the screw tightens. Both achieve equivalent electrical and mechanical connection reliability within their specified torque ranges.

Q: Is the TE Connectivity 1546073-3 suitable for applications originally designed for the 1753840000?

A: Yes. The part meets or exceeds all critical parameters: pitch, position count, mating orientation, electrical ratings, and through-hole mounting. The higher current rating (17.5 A) and wider wire gauge range (12-30 AWG) provide design margin. The M3 screw thread matches the original. Verify REACH compliance requirements for your supply chain, as this part is REACH affected.

Q: Why does the 1716050000 have a narrower wire gauge range than the original?

A: The Omnimate LM series (1716050000) is optimized for 14-24 AWG wire, while the obsolete Omnimate LP series (1753840000) accepted 12-26 AWG. This reflects design evolution in the product line. Confirm your application wire gauge falls within 14-24 AWG before selecting this substitute.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 1716050000 is RoHS compliant. The 1546073-3 is ROHS3 compliant, which is a more recent standard. Both meet modern regulatory requirements. The 1753840000 is RoHS compliant but obsolete.

Q: What torque specification should be used for the 1716050000?

A: Apply 0.4-0.5 Nm (4.6-4.4 Lb-In) for the M2.5 screw thread. This differs from the original 0.5-0.6 Nm specification for M3. Update assembly procedures accordingly.
