DS40MB200SQ Equivalent & Substitute Parts Engineering Reference

Part Overview

The DS40MB200SQ is a buffer, multiplexer IC with a configuration of 2 x 1:2, 2:1 channel selection, supporting up to 4Gbps data rate, designed for surface mount in a 48-WQFN (7x7) package. It provides CML input/output, input equalization, and output pre-emphasis. The part is classified as obsolete, which necessitates evaluating alternative or equivalent models to maintain functionality in existing designs or for new requirements where original inventory is depleted or unavailable.

Substitute Part Grouping Explanation

Substitution is determined strictly by matching the following key parameters: type, input/output standard, data rate (max), number of channels, delay time, signal conditioning, supply voltage, operating temperature range, mounting type, package/case, and device package. Only parts with equivalent values for these fields are considered parametric equivalents for the DS40MB200SQ. Substitute parts must also be available in a compatible RoHS compliance and MSL classification, and share the same mounting and mechanical envelope.

Engineering Selection Recommendations

When selecting a substitute for the DS40MB200SQ, product status is a primary consideration, as the DS40MB200SQ is obsolete while DS40MB200SQ/NOPB and DS42MB200TSQ/NOPB are both active. For compliance, DS40MB200SQ/NOPB and DS42MB200TSQ/NOPB are ROHS3 compliant, whereas DS40MB200SQ is RoHS non-compliant. All parts share the same MSL (3, 168 hours) and meet the specified REACH and ECCN standards. The supply voltage, package, and electrical characteristics are equivalent or higher for substitute parts.
