Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1618350000 is determined by strict alignment of the following critical parameters:

Position Count and Pitch: 24 positions at 0.138" (4.60mm) spacing
Connector Type and Orientation: Male pins, shrouded (4-side), 90° right-angle configuration
Electrical Ratings: Voltage and current capacity within or exceeding IEC/UL specifications
Termination Method: Solder-based through-hole mounting
Material Compliance: UL94 V-0 flammability rating and REACH compliance

The On Shore Technology Inc. OSTOQ241551 meets these core substitution criteria, sharing identical position count, pitch, connector type, orientation, and termination method. Both parts maintain equivalent shrouded male pin designs and comply with relevant regulatory standards.

Engineering Selection Recommendations

The On Shore Technology OSTOQ241551 serves as a direct functional substitute for the obsolete Weidmüller 1618350000. Both components share identical mechanical and electrical specifications across all critical parameters: 24-position configuration, 4.60mm pitch, 90° right-angle male pin shrouded design, and solder termination.

The OSTOQ241551 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The substitute part exceeds the original specification in operating temperature range (-30°C to 105°C versus -20°C to 100°C), providing enhanced thermal performance for demanding applications. Both parts maintain UL94 V-0 flammability compliance and REACH regulatory alignment.

Selection of the OSTOQ241551 is supported by equivalent electrical ratings (300V UL), matching contact materials and finishes, and identical shrouded connector architecture. The transition from the obsolete Weidmüller part to the active On Shore Technology equivalent presents no functional or compatibility constraints for PCB-level integration.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ241551 be used as a direct replacement for the 1618350000 in existing designs?

A: Yes. Both parts share identical position count (24), pitch (4.60mm), connector type (male pins, shrouded 4-side), orientation (90° right-angle), and termination method (solder). Mechanical and electrical compatibility is confirmed across all specified parameters.

Q: What is the primary advantage of switching to the OSTOQ241551?

A: The OSTOQ241551 maintains active product status, ensuring reliable supply chain availability. The original Weidmüller 1618350000 is classified as obsolete, making the substitute the preferred choice for new designs and ongoing production.

Q: Are there electrical rating differences between the two parts?

A: Both parts support 300V UL rating. The OSTOQ241551 operates across a wider temperature range (-30°C to 105°C) compared to the original part (-20°C to 100°C), providing additional thermal margin for industrial applications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 1618350000 and OSTOQ241551 carry UL94 V-0 flammability ratings, REACH Unaffected status, and EAR99 export classification. Regulatory compliance is equivalent.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching position count, pitch spacing, connector type and shrouding, orientation, termination method, electrical ratings (voltage/current), flammability compliance, and contact material specifications. The OSTOQ241551 aligns with all these criteria.
