Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1618000000 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 19 positions at 0.138" (4.60mm) spacing
• Physical Configuration: 90° right-angle orientation with shrouded (4-side) male pin design
• Electrical Ratings: Voltage and current capacity within or exceeding IEC/UL specifications
• Termination Method: Solder-compatible through-hole mounting
• Environmental Compliance: Operating temperature range and material certifications

The On Shore Technology Inc. OSTOQ191251 meets these core substitution criteria, maintaining identical position count, pitch, orientation, and shrouded male pin configuration. Both parts support solder termination and operate within compatible electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ191251 is the qualified substitute for the obsolete Weidmüller 1618000000. Selection is based on the following engineering factors:

Functional Equivalence: Both parts maintain identical mechanical and electrical specifications for the 19-position, 4.6mm pitch, 90° right-angle shrouded header configuration. Pin count, spacing, and connector geometry ensure direct form-fit-function compatibility.

Product Status: The OSTOQ191251 is in active production status, ensuring long-term availability and supply chain continuity. The Weidmüller part's obsolete status necessitates transition to an equivalent active component.

Compliance & Certifications: Both parts carry REACH Unaffected and EAR99 export classification status. The OSTOQ191251 includes RoHS3 compliance certification, meeting current regulatory requirements for new designs and manufacturing.

Electrical Performance: The OSTOQ191251 meets or exceeds the voltage rating (300V UL) of the original part. Operating temperature range of -30°C ~ 105°C provides extended environmental capability compared to the original -20°C ~ 100°C specification.

Contact & Housing Materials: Tin-plated contact finish and thermoplastic housing in the substitute part maintain electrical and mechanical performance standards equivalent to the original copper alloy and PBT construction.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ191251 be used as a direct replacement for the 1618000000 in existing designs?

A: Yes. Both parts share identical position count (19), pitch (4.6mm), orientation (90° right-angle), and shrouded male pin configuration. Solder termination compatibility and electrical ratings (300V UL) ensure functional equivalence in through-hole PCB applications.

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

A: The primary differences are manufacturer (Weidmüller vs. On Shore Technology), product status (obsolete vs. active), contact material (copper alloy vs. brass), and housing material (PBT vs. thermoplastic). The OSTOQ191251 offers an extended operating temperature range (-30°C ~ 105°C vs. -20°C ~ 100°C) and includes RoHS3 compliance.

Q: Are there any mechanical compatibility concerns when substituting?

A: No. Both parts maintain the same 19-position configuration at 4.6mm pitch with 90° right-angle orientation and shrouded design. PCB footprint and mounting hole patterns are compatible.

Q: What is the significance of the product status difference?

A: The Weidmüller 1618000000 is obsolete, meaning it is no longer manufactured and inventory is limited. The OSTOQ191251 is in active production, ensuring reliable availability for current and future applications.

Q: Does the OSTOQ191251 meet current regulatory requirements?

A: Yes. The OSTOQ191251 is RoHS3 compliant and carries REACH Unaffected status, meeting current environmental and export regulations. The original Weidmüller part does not specify RoHS compliance.

Q: Are the electrical ratings sufficient for the same applications?

A: Yes. The OSTOQ191251 maintains the 300V UL voltage rating and supports solder termination equivalent to the original part. The extended operating temperature range provides additional margin for demanding environments.
