Substitute Part Grouping Explanation
The QSE-028-01-L-D-DP-A-TR and QSE-028-01-L-D-DP-A are functionally equivalent based on the following critical parameters:
- Identical connector type, position count, and pitch
- Identical mounting type and surface mount configuration
- Identical contact finish and finish thickness
- Identical electrical and mechanical features (board guide, ground bus)
- Identical compliance certifications (ROHS3, MSL 1)
- Same base product number (QSE-028)
The sole difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Tray format. This distinction affects only logistics and assembly line integration, not component performance or compatibility.

Engineering Selection Recommendations
Both QSE-028-01-L-D-DP-A-TR and QSE-028-01-L-D-DP-A are active production parts with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts depends on assembly process requirements:
- QSE-028-01-L-D-DP-A-TR is appropriate for automated pick-and-place assembly using tape-fed component feeders.
- QSE-028-01-L-D-DP-A is appropriate for manual assembly or systems using tray-based component handling.
Both parts meet identical electrical and mechanical specifications and are suitable for differential pair array applications requiring 56-position surface mount connectors with 0.031" pitch.
Frequently Asked Questions (FAQ)
Q: Are QSE-028-01-L-D-DP-A-TR and QSE-028-01-L-D-DP-A electrically identical?
A: Yes. Both parts have identical connector type, position count, pitch, contact finish, and electrical features. They are functionally equivalent for all circuit applications.
Q: What is the difference between Tape & Reel and Tray packaging?
A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place machines. Tray packaging supplies components in static-protective trays suitable for manual assembly or alternative handling systems. The component itself is unchanged.
Q: Can I substitute QSE-028-01-L-D-DP-A for QSE-028-01-L-D-DP-A-TR in my design?
A: Yes, provided your assembly process can accommodate tray-based component handling. The electrical and mechanical specifications are identical.
Q: Are both parts RoHS compliant?
A: Yes. Both QSE-028-01-L-D-DP-A-TR and QSE-028-01-L-D-DP-A are ROHS3 compliant.
Q: What is the moisture sensitivity level for these connectors?
A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
