Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-SATA/7-M-BO-D-01-03-R is determined by strict alignment across the following critical parameters:

• Connector Type & Position Count: Must be SATA with exactly 7 positions
• Physical Form Factor: Header configuration with shrouded design
• Mounting & Termination: Through-hole solder termination required
• Functional Features: Board lock capability must be present
• Contact Material & Finish: Gold plating required
• Environmental Rating: MSL 1 (Unlimited) classification

The substitute part 0471554001 (Molex) meets all these criteria, establishing direct functional equivalence for PCB-level integration.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0471554001 serves as the direct functional equivalent for the obsolete Assmann A-SATA/7-M-BO-D-01-03-R. Selection of the Molex substitute is supported by:

• Identical electrical and mechanical specifications across all critical connector parameters
• Active product status ensuring ongoing availability and supply chain stability
• Equivalent regulatory compliance with REACH Unaffected and EAR99 classifications matching the original part
• RoHS3 compliance of the substitute part, providing enhanced environmental and regulatory alignment
• Established availability with 5735 units in stock versus the obsolete status of the original

For new designs or production transitions, the Molex 0471554001 is the appropriate selection. For legacy systems currently using the Assmann connector, the Molex part provides direct substitution without PCB redesign or connector interface modification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0471554001 be used as a direct replacement without PCB modifications?

A: Yes. Both connectors share identical connector type (SATA), position count (7), shrouded header form factor, through-hole solder termination, board lock features, and gold contact finish. No PCB layout changes are required.

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

A: The Assmann part is obsolete, indicating discontinued manufacturing and limited future availability. The Molex substitute is active, ensuring reliable long-term supply for production and maintenance applications.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry identical REACH Unaffected and EAR99 classifications. The Molex part additionally carries RoHS3 compliance certification, providing enhanced regulatory alignment with current environmental standards.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (Tray for Molex versus unspecified for Assmann) does not affect electrical or mechanical compatibility. Packaging differences are relevant only for procurement, storage, and handling procedures.

Q: What parameters must remain constant for substitution validity?

A: Connector type, position count, shrouded header style, through-hole mounting, solder termination, board lock feature, gold contact finish, and MSL rating must all match. Any deviation in these parameters invalidates substitution.
