Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1774902001 is determined by the following critical parameters:

• Number of Positions: Must be 16
• Pitch: Must be 0.200" (5.08mm)
• Header Orientation: Must be 90°, Right Angle
• Type: Must be Header with Male Pins, Shrouded (2 Side)
• Voltage Rating (UL): Must support minimum 300 V
• Contact Mating Finish: Tin plating
• Mounting Compatibility: Through-hole solder mounting

The On Shore Technology Inc. OSTOQ165351 meets these core substitution criteria, providing functional equivalence for applications requiring 16-position, 5.08mm pitch terminal block headers with right-angle orientation.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ165351 is an active product with current manufacturing status, providing continuity for applications previously using the obsolete Weidmüller 1774902001. Both components maintain equivalent electrical ratings at 300 V UL and share identical pitch, position count, and connector orientation specifications.

The OSTOQ165351 demonstrates compliance with ROHS3 standards and maintains REACH unaffected status, consistent with the original component's regulatory profile. The operating temperature range of -30°C ~ 105°C on the substitute part encompasses the majority of the original -50°C ~ 100°C specification, with the upper limit providing additional thermal margin.

Both components carry MSL 1 (Unlimited) moisture sensitivity classification and share identical ECCN and HTSUS codes, indicating equivalent trade and export compliance characteristics.

Frequently Asked Questions (FAQ)

Q: What makes the OSTOQ165351 a suitable substitute for the 1774902001?

A: The OSTOQ165351 matches all critical functional parameters: 16 positions, 0.200" (5.08mm) pitch, 90° right-angle orientation, male pins with two-side shrouding, and 300 V UL voltage rating. Both components use tin contact mating finish and support through-hole solder mounting.

Q: Are there differences in operating temperature ranges between these parts?

A: The original Weidmüller part operates from -50°C to 100°C, while the OSTOQ165351 operates from -30°C to 105°C. For applications requiring operation below -30°C, the original specification must be verified against actual system requirements.

Q: What is the significance of the different contact materials?

A: The Weidmüller 1774902001 uses copper alloy contacts, while the OSTOQ165351 uses brass contacts. Both materials provide adequate electrical conductivity and tin plating compatibility for standard terminal block applications.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. The Weidmüller part is RoHS Compliant, and the OSTOQ165351 is ROHS3 Compliant. Both maintain REACH unaffected status and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the difference between "Through Hole" and "Solder" mounting types listed for these parts?

A: Both components are designed for solder mounting to PCBs. The terminology reflects different specification conventions used by manufacturers; both parts are suitable for through-hole PCB assembly processes.

Q: Is the OSTOQ165351 available in the same packaging as the original part?

A: The OSTOQ165351 is supplied in bulk packaging. Packaging configuration should be confirmed with the supplier based on specific procurement requirements.
