Engineering Selection Recommendations

Both the main part (SL-122-TT-12, Active status) and the substitute part (SL-122-TT-12, Discontinued at DiGi Electronics) are electrically and mechanically identical across all provided specifications. Selection between these parts should be based on the following factors:

Primary Part Selection: The main part SL-122-TT-12 with Active product status is recommended for new designs and ongoing production due to its current availability and manufacturer support status.

Substitute Part Consideration: The substitute part, while discontinued at DiGi Electronics, maintains full electrical and mechanical equivalence and is available in higher inventory quantity (1119 pieces versus 650 pieces). This part may be selected for existing designs requiring additional stock or when procurement from alternative distributors is feasible.

Compliance Assurance: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. Both parts are identical in connector type, contact configuration, pitch, material composition, and operating temperature range. They are direct electrical equivalents.

Q: What is the difference between the main part and the substitute? A: The parts are functionally identical. The primary difference is product status: the main part is Active, while the substitute is Discontinued at DiGi Electronics. Inventory levels also differ (650 vs. 1119 pieces).

Q: Can I use the substitute part in place of the main part? A: Yes. The substitute part meets all electrical and mechanical requirements for direct substitution in board-to-board connector applications.

Q: Are there any packaging differences? A: Packaging information for the substitute part is not specified in the available data. Verify packaging requirements with your supplier before procurement.

Q: Do both parts meet the same compliance standards? A: Yes. Both parts are ROHS3 compliant with MSL 1 rating, meeting the same regulatory and environmental standards.

Q: What should I consider when selecting between these parts? A: Consider product status (Active vs. Discontinued), inventory availability, and distributor accessibility. For new designs, the Active part is preferred. For existing designs requiring additional stock, the substitute may be selected based on availability from alternative sources.
