Substitute Part Grouping Explanation
Substitution for the QSE-020-01-C-D-A-TR is determined by strict equivalence across the following critical parameters:
- Connector type and contact configuration (Receptacle, Center Strip Contacts)
- Electrical specifications (40 positions, 0.031" pitch, 2 rows)
- Physical dimensions (0.128" height above board, mated stacking heights)
- Surface finish specifications (Gold, 50.0µin thickness)
- Mechanical features (Board Guide, Ground Bus Plane)
- Compliance certifications (ROHS3, MSL 1)
- Manufacturer (Samtec Inc.)
- Series designation (Q Strip® QSE)
The primary variable among equivalent parts is packaging format. The QSE-020-01-C-D-A-TR is supplied in tape and reel format, while substitute configurations may use alternative packaging such as tray or bulk formats. All other electrical, mechanical, and compliance parameters remain identical across the substitute group.

Engineering Selection Recommendations
Both the QSE-020-01-C-D-A-TR and QSE-020-01-C-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement constraints.
The QSE-020-01-C-D-A-TR in tape and reel format is optimized for high-volume automated assembly operations. The QSE-020-01-C-D-A in tray packaging is suitable for lower-volume applications or when tape and reel format is unavailable.
Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and storage conditions. No functional or performance differences exist between these configurations.
Frequently Asked Questions (FAQ)
Q: Are QSE-020-01-C-D-A-TR and QSE-020-01-C-D-A electrically and mechanically identical?
A: Yes. Both parts are functionally equivalent. They share identical connector type, position count, pitch, mounting type, contact finish, and physical dimensions. The only difference is packaging format.
Q: What is the difference between tape and reel (TR) and tray packaging?
A: Tape and reel packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume production. Tray packaging is used for manual assembly, lower-volume applications, or when tape and reel format is unavailable. Both formats contain the same component.
Q: Can I use QSE-020-01-C-D-A as a direct replacement for QSE-020-01-C-D-A-TR?
A: Yes, provided your assembly process can accommodate tray packaging. The electrical and mechanical specifications are identical, and both parts meet the same compliance standards.
Q: Are there any compliance or certification differences between these parts?
A: No. Both parts carry ROHS3 compliance and MSL 1 rating. No functional or regulatory differences exist.
Q: What are the mated stacking height options for this connector?
A: The QSE-020-01-C-D-A-TR and QSE-020-01-C-D-A support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, allowing flexibility in system design and interconnect requirements.
