Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761450625 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Voltage rating (30V), contact finish composition and thickness (gold, 30.0µin), and differential pair configuration (96 differential pairs).

Mechanical Parameters: Connector position count (288), pitch spacing (0.053"/1.35mm), row and column configuration (18×16), mounting method (through hole), and termination type (press-fit).

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

Series Consistency: Both parts belong to the Impact 76145 series, ensuring design compatibility within the product family.

The identified substitute part (0761451625) meets all these criteria, differing only in packaging configuration and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761451625 is the direct functional equivalent of the 0761450625. Both parts are manufactured by Molex within the Impact 76145 series and maintain complete electrical and mechanical compatibility.

Primary Advantage: The substitute part (0761451625) carries Active product status, ensuring long-term availability and continued manufacturer support. The original part (0761450625) is classified as Obsolete, which restricts future procurement options and may impact supply chain continuity.

Compliance Alignment: Both parts maintain identical RoHS3 compliance and UL94 V-0 flammability certification, meeting current regulatory requirements for electronic component deployment.

Packaging Consideration: The substitute is supplied in Tray packaging, which may differ from the original part's packaging specification. Verify that tray packaging is compatible with your assembly and storage procedures.

Inventory Status: Current stock availability shows 972 units of the substitute part versus 956 units of the original part, providing adequate supply for procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the 0761451625 be used as a direct replacement for the 0761450625 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector position count, pitch, mounting type, contact finish, voltage rating, and operating temperature range. No design modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturer support lifecycle. The substitute part's Active status ensures continued availability, technical support, and compliance updates from Molex. The original part's Obsolete status may result in limited future procurement options and eventual discontinuation of supply.

Q: Does the packaging difference (Tray vs. unspecified) affect electrical performance?

A: No. Packaging affects only handling, storage, and logistics. The electrical and mechanical specifications of the connector itself remain identical. Verify that Tray packaging is compatible with your receiving, storage, and assembly processes.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 0761450625 and 0761451625 are ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: What is the differential pair configuration for these connectors?

A: Both parts feature 96 differential pairs within the 288-position configuration, supporting high-speed differential signaling applications.

Q: Are there any restrictions on operating temperature or environmental conditions?

A: Both parts operate within the range of -55°C to 85°C and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control requirements during storage or handling.
