Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1858000000 is determined by the following critical parameters:

Electrical Compatibility: Current and voltage ratings must meet or exceed the original specifications (IEC: 18A/400V; UL: 15A/300V)
Physical Compatibility: Number of positions (13), pitch (0.200"/5.08mm), header orientation (90° right angle), and shrouded male pin configuration must be identical
Termination and Mounting: Solder termination and through-hole mounting type must match
Environmental Compliance: Operating temperature range (-50°C ~ 100°C), flammability rating (UL94 V-0), and RoHS compliance must be maintained
Contact and Housing Materials: Copper alloy contacts and appropriate housing material composition

The substitute part Weidmüller 1155700000 meets these criteria with enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The Weidmüller 1155700000 is the direct substitute for the obsolete 1858000000. Both components are manufactured by Weidmüller within the Omnimate SL series and maintain identical physical and functional specifications for the 13-position, 5.08mm pitch configuration.

The 1155700000 offers the following advantages:

Active Product Status: Currently in active production with confirmed inventory availability (1091 pcs in stock)
Enhanced Electrical Ratings: Provides higher current capacity (24A IEC / 18.5A UL) compared to the original (18A IEC / 15A UL), ensuring superior performance margin
Compliance Maintenance: Maintains all required certifications including RoHS compliance, REACH unaffected status, and UL94 V-0 flammability rating
Mechanical Compatibility: Identical pitch, position count, orientation, and mounting type ensure direct PCB compatibility without redesign

The substitute part is suitable for direct replacement in applications where the original 1858000000 was specified, with the added benefit of improved electrical performance and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 1155700000 be used as a direct replacement for the 1858000000 on existing PCBs?

A: Yes. Both parts share identical pitch (5.08mm), position count (13), orientation (90° right angle), and through-hole mounting specifications. No PCB redesign is required.

Q: What is the difference in electrical performance between these two parts?

A: The 1155700000 provides higher current ratings (24A IEC vs. 18A IEC; 18.5A UL vs. 15A UL) while maintaining the same voltage specifications (400V IEC / 300V UL). This represents an improvement in current-carrying capacity.

Q: Are there any material differences between the two parts?

A: The housing material differs: the 1858000000 uses Polybutylene Terephthalate (PBT), while the 1155700000 uses Polyamide (PA) Nylon, Glass Filled. Both materials meet UL94 V-0 flammability requirements. The 1155700000 also features interlocking on the side for enhanced mechanical retention.

Q: What is the insulation height difference, and does it affect compatibility?

A: The 1858000000 has an insulation height of 0.330" (8.38mm), while the 1155700000 measures 0.472" (12.00mm). This difference does not affect PCB compatibility but may impact clearance in space-constrained applications. Verify available vertical clearance in your assembly.

Q: Why is the original part obsolete, and what is the recommended action?

A: The 1858000000 is classified as obsolete by Weidmüller. For new designs and production runs, the 1155700000 is the recommended active substitute. Existing inventory of the original part should be managed according to your supply chain strategy.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1858000000 and 1155700000 are RoHS compliant and REACH unaffected, meeting current environmental regulations.

Q: What packaging options are available for the substitute part?

A: The 1155700000 is supplied in bulk packaging, compared to the original part's unspecified packaging. Confirm packaging requirements with your procurement process.
