Substitute Part Grouping Explanation

Substitution of the SBH-ST-29-SM-ML is determined by strict equivalence across the following parameters:

• Connector Type: SAS
• Number of Positions: 29
• Connector Style: Plug
• Mounting Type: Surface Mount
• Termination Method: Solder
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• RoHS Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 10045105-001LF meets all these criteria and is manufactured by Amphenol ICC (FCI), an active product with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries active product status with confirmed inventory availability, ensuring supply chain continuity. Both parts satisfy RoHS compliance requirements and carry equivalent moisture sensitivity ratings. The Amphenol ICC part includes a board guide feature, providing additional mechanical stability during assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the 10045105-001LF be used as a direct replacement for the SBH-ST-29-SM-ML?

A: Yes. Both connectors share identical specifications for connector type (SAS), position count (29), mounting method (surface mount), termination (solder), contact finish (gold at 30.0µin thickness), and compliance ratings (RoHS, MSL 1). The parts are electrically and mechanically interchangeable.

Q: What is the difference between the flange feature on the 3M part and the board guide on the Amphenol ICC part?

A: Both features provide mechanical positioning and stability during assembly. The flange and board guide serve equivalent functional purposes in securing the connector to the PCB during solder reflow operations.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are RoHS compliant, carry MSL 1 rating (unlimited moisture sensitivity), and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Why is the 3M part listed as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions. The Amphenol ICC equivalent remains in active production, ensuring continued availability for applications requiring this connector specification.

Q: What packaging format is available for the substitute part?

A: The 10045105-001LF is supplied in tray packaging, consistent with the original SBH-ST-29-SM-ML packaging format.
