Frequently Asked Questions (FAQ)

Q: What defines compatibility for substitute parts with the MMS-118-02-L-SH?

A: Substitute parts must match the following parameters: 18-position receptacle connector, 0.079" (2.00mm) mating pitch, surface mount right-angle mounting, female socket contacts, 3.9A per contact current rating, and -55°C to 125°C operating temperature range.

Q: Are there cross-manufacturer alternatives available for this connector?

A: Based on the provided reference data, no cross-manufacturer alternatives have been specified. The MMS-118-02-L-SH is listed as its own substitute within the Samtec MMS series.

Q: What is the significance of the MSL 1 rating for this connector?

A: MSL 1 (Unlimited) indicates this connector has no moisture sensitivity constraints. It can be stored and handled without time-limited exposure restrictions, simplifying inventory management and supply chain logistics.

Q: How does the contact finish specification impact substitution decisions?

A: The gold-plated mating contacts (10.0µin/0.25µm thickness) with tin-plated post contacts are integral to the electrical performance specification. Substitute parts must maintain identical contact finish specifications to ensure equivalent signal integrity and reliability.

Q: What compliance certifications should be verified when sourcing this connector?

A: Verify ROHS3 compliance and REACH unaffected status. The part's active product status ensures ongoing manufacturer support and supply availability.
