• Termination Method: Both use solder termination
• Connector Style: Both feature center strip contacts
• Board-to-Board Application: Both are designed for board-to-board interconnection
• Contact Finish: Both utilize gold plating
• Series Family: Both belong to the CHAMP .050 I series

The substitute part 1734100-5 maintains functional and mechanical compatibility with the original 557102-9 while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 1734100-5 serves as the direct active equivalent for the obsolete 557102-9. Selection of the substitute part is supported by the following factors:

Product Status: The 1734100-5 maintains active product status, ensuring continued availability and manufacturer support, whereas the 557102-9 is classified as obsolete.

Regulatory Compliance: The 1734100-5 achieves ROHS3 compliance and REACH Unaffected status, providing superior environmental and regulatory alignment compared to the non-compliant 557102-9.

Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, row configuration, mounting type, termination method, and contact finish.

Availability: The 1734100-5 demonstrates higher inventory levels (2300 units) relative to the 557102-9 (765 units), supporting supply chain continuity.

For new designs and production transitions, the 1734100-5 is the appropriate selection. For legacy system maintenance where the original 557102-9 is required, existing inventory remains available.

Frequently Asked Questions (FAQ)

Q: Can the 1734100-5 directly replace the 557102-9 in existing applications?

A: Yes. Both connectors share identical specifications for connector type, position count, row configuration, mounting type, termination method, connector style, and board-to-board application. The 1734100-5 maintains functional and mechanical compatibility with the 557102-9.

Q: What is the primary difference between these two parts?

A: The 557102-9 is obsolete with RoHS non-compliant status, while the 1734100-5 is an active product with ROHS3 compliance and REACH Unaffected certification. The 1734100-5 also omits the board guide feature present in the 557102-9, retaining only the board lock feature.

Q: Are there packaging differences between the two parts?

A: The 1734100-5 is supplied in box packaging. Packaging information for the 557102-9 was not specified in the available data.

Q: Do both parts have the same contact finish specifications?

A: Both parts feature gold-plated contacts. The 557102-9 specifies a contact finish thickness of 30.0µin (0.76µm), while the 1734100-5 specifies flash plating.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 557102-9 and 1734100-5 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Which part should be selected for new designs?

A: The 1734100-5 should be selected for new designs due to its active product status, ROHS3 compliance, and REACH Unaffected certification.
