Substitute Part Grouping Explanation

Substitution of the obsolete 1-557100-7 is based on electrical and mechanical parameter equivalence within the CHAMP .050 I series. The substitute part 1734099-7 maintains identical specifications across all critical parameters: 68-position plug configuration, 2-row arrangement, through-hole right-angle mounting, solder termination, center strip contact style, board-to-board application, board lock feature, and gold contact finish.

The primary distinction between the main part and substitute is product status and compliance certification. The substitute part 1734099-7 is active in production and carries ROHS3 compliance, whereas the main part is obsolete and RoHS non-compliant. Both parts share the same series designation and functional characteristics, establishing direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1734099-7 is the direct equivalent for the obsolete 1-557100-7. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 1-557100-7 is obsolete and no longer in active production. The substitute 1734099-7 is active and maintains full production availability with 4145 pieces in current inventory.

Compliance Certification: The substitute part 1734099-7 carries ROHS3 compliance, meeting current regulatory requirements for electronic components in most jurisdictions. The main part is RoHS non-compliant and does not meet modern environmental standards.

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

Series Continuity: Both parts belong to the CHAMP .050 I series, ensuring design compatibility and interchangeability within existing circuit board layouts and connector mating interfaces.

For new designs and ongoing procurement, the substitute part 1734099-7 is the appropriate selection. For legacy systems currently utilizing 1-557100-7, direct substitution with 1734099-7 is electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can 1734099-7 directly replace 1-557100-7 in existing applications?

A: Yes. Both parts are identical in electrical and mechanical specifications. The 68-position plug configuration, through-hole right-angle mounting, solder termination, and board-to-board interface are equivalent. Direct substitution is compatible.

Q: What is the primary reason for substitution?

A: The main part 1-557100-7 is obsolete and no longer manufactured. The substitute 1734099-7 is an active production part from the same manufacturer and series, providing continued availability and compliance with current regulatory standards.

Q: Are there compliance differences between the two parts?

A: Yes. The substitute part 1734099-7 is ROHS3 compliant, while the main part 1-557100-7 is RoHS non-compliant. For applications subject to RoHS regulations, the substitute part is required.

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

A: Both parts feature gold contact finish. The main part specifies 30.0µin (0.76µm) thickness, while the substitute part specifies flash thickness. Both finishes are suitable for solder termination and board-to-board applications.

Q: What is the packaging difference?

A: The main part 1-557100-7 packaging is not specified in available documentation. The substitute part 1734099-7 is supplied in tray packaging. Confirm packaging requirements with procurement specifications.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in new designs?

A: Yes. For new designs, the substitute part 1734099-7 is the appropriate selection due to active production status and ROHS3 compliance. The electrical and mechanical specifications ensure full compatibility with existing CHAMP .050 I series connector interfaces.
