Substitute Part Grouping Explanation

Substitution for the Molex 0760552104 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters: Voltage rating (30V), contact finish composition and thickness (gold, 30.0µin), and differential pair configuration (50 pairs).

Mechanical Parameters: Connector position count (150), pitch (0.053"/1.35mm), row and column configuration (15×10), mounting method (through-hole), and termination type (press-fit).

Environmental & Compliance Parameters: Operating temperature range (-55°C to 85°C), material flammability rating (UL94 V-0), RoHS3 compliance, and moisture sensitivity level (MSL 1).

Series Consistency: Both parts belong to the Molex Impact 76055 series, ensuring design and footprint compatibility.

The substitute part 0760553104 meets all these criteria and is classified as active product status, providing improved supply availability compared to the obsolete main part.
