Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 552726-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 5552726-3 maintains identical specifications across the following critical parameters:

• Connector type (Plug)
• Position count (50 positions)
• Row configuration (2 rows)
• Mounting configuration (Panel Mount, Through Hole, Right Angle)
• Termination method (Solder)
• Series designation (CHAMP .085)
• Connector style (Center Strip Contacts)
• Flange feature (Tapped, Threaded 4-40)
• Contact finish material (Gold)
• Contact finish thickness (30.0µin / 0.76µm)

The primary distinction between the main part and its substitute is product status and compliance certification. The substitute part 5552726-3 is active and RoHS3 compliant, whereas the original 552726-3 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5552726-3 is the direct equivalent for the obsolete 552726-3. Selection of the substitute part is based on the following engineering criteria:

Product Status: The original part 552726-3 is classified as obsolete. The substitute 5552726-3 maintains active product status, ensuring continued availability and manufacturer support.

Regulatory Compliance: The substitute part 5552726-3 is RoHS3 compliant, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant and does not satisfy modern procurement standards for many applications.

Electrical and Mechanical Equivalence: All functional parameters remain identical between the main part and substitute, including connector configuration, position count, mounting method, termination type, and contact specifications.

Packaging: The substitute part is supplied in tray packaging, which is standard for production environments and provides improved handling and inventory management compared to unspecified packaging.

For new designs, repair operations, and production applications requiring the 50 position D-Sub plug connector in the CHAMP .085 series with right angle solder termination, the 5552726-3 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 5552726-3 substitute directly for the 552726-3 in existing designs?

A: Yes. The 5552726-3 is electrically and mechanically equivalent to the 552726-3. All connector parameters, including position count, mounting configuration, termination method, and contact specifications, are identical. The substitute part can be used as a direct replacement without design modification.

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

A: The main differences are product status and regulatory compliance. The 552726-3 is obsolete and RoHS non-compliant, while the 5552726-3 is active and RoHS3 compliant. Functionally, both parts are identical.

Q: Why should I use the 5552726-3 instead of the 552726-3?

A: The 552726-3 is obsolete and no longer actively manufactured or supported. The 5552726-3 is the active equivalent that ensures component availability, manufacturer support, and compliance with current environmental regulations. For new production and ongoing applications, the 5552726-3 is the appropriate choice.

Q: Are there any compatibility concerns when switching from 552726-3 to 5552726-3?

A: No compatibility concerns exist. Both parts are from the same manufacturer (TE Connectivity AMP Connectors), belong to the same series (CHAMP .085), and share identical electrical and mechanical specifications. The parts are pin-for-pin and form-fit compatible.

Q: What is the packaging difference between these parts?

A: The 552726-3 packaging is not specified in available documentation. The 5552726-3 is supplied in tray packaging, which is standard for production environments and provides organized component handling and storage.

Q: Are the contact specifications identical?

A: Yes. Both parts feature gold contact finish with 30.0µin (0.76µm) thickness. Contact material, finish type, and thickness specifications are identical between the two parts.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited moisture sensitivity. These connectors do not require special moisture control during storage or handling.
