Tin-Plated Mating Contact Options: Amphenol 67996-418HLF and 67997-418HLF provide tin-plated mating contacts for applications where this finish is specified.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the Molex 0010892181 with any of these substitute parts?

A: All listed substitute parts share the core electrical and mechanical parameters: 18 positions, 2 rows, 0.100" (2.54mm) pitch, male pins, through-hole solder termination, and push-pull fastening. Physical and electrical compatibility is established for these parameters. Verify application-specific requirements such as contact finish, operating temperature range, and insulation material before final selection.

Q: What is the difference between the Amphenol 67996 and 67997 series?

A: Both series are BERGSTIK II headers with identical core specifications. The primary difference is contact finish thickness on mating contacts: 67996 series offers 30.0µin (0.76µm) or 15.0µin (0.38µm) gold finish, while 67997 series provides 30.0µin (0.76µm) or 15.0µin (0.38µm) gold finish. The 418HLF variants in both series feature tin mating contact finish. Operating temperature range extends to 130°C for 67997 series versus 125°C for 54102-S0809LF.

Q: Why is the 3M 2318-6121-TG listed if it is RoHS non-compliant?

A: The 3M part is included as a documented substitute based on the provided input data. However, for new designs and production requiring RoHS compliance, alternative parts with ROHS3 or RoHS Compliant status are recommended.

Q: Does contact finish affect electrical performance?

A: Contact finish affects corrosion resistance, wear characteristics, and long-term reliability in specific environments. Gold-plated contacts provide superior corrosion resistance and are preferred for applications with extended shelf life or harsh environmental exposure. Tin-plated contacts are suitable for standard applications with regular use cycles.

Q: Are there packaging differences among the substitute parts?

A: Yes. Packaging varies between Bulk and Bag formats. Mill-Max 450-90-218-00-006000 and Amphenol 67997-218HLF are supplied in Bulk packaging, while most Amphenol BERGSTIK II variants are supplied in Bag packaging. 3M 2318-6121-TG and TE Connectivity 5-146256-9 are supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the "HLF" suffix in Amphenol part numbers?

A: The HLF suffix indicates lead-free termination processing, consistent with RoHS compliance requirements. This designation confirms the part meets lead-free soldering standards.

Q: Can I use the Mill-Max 450-90-218-00-006000 as a direct replacement?

A: The Mill-Max part meets core mechanical and electrical parameters but differs in contact shape (circular versus square), contact material (brass alloy versus phosphor bronze), and contact finish (tin-lead versus gold). These differences may affect performance in specific applications. Evaluate compatibility based on your circuit board design and application requirements.
