Substitute Part Grouping Explanation
Substitution eligibility for the QSE-020-01-H-D-A-K is determined by equivalence across the following critical parameters:
- Connector type and contact configuration (Receptacle, Center Strip Contacts)
- Electrical specifications (40 positions, 0.031" pitch, 2 rows)
- Mechanical dimensions (Height above board: 0.128", mated stacking heights)
- Surface finish specifications (Gold plating, 30.0µin thickness)
- Mounting technology (Surface Mount with Board Guide and Ground Bus)
- Compliance certifications (ROHS3, MSL 1)
The identified substitute part differs only in packaging format, which does not affect electrical or mechanical performance. Both the tray and tape & reel packaging options are suitable for equivalent component selection based on supply chain and assembly process requirements.

Engineering Selection Recommendations
Both QSE-020-01-H-D-A-K and QSE-020-01-H-D-A-K-TR are active production parts with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements:
The tray packaging (QSE-020-01-H-D-A-K) is suitable for lower-volume applications and manual assembly processes. The tape & reel packaging (QSE-020-01-H-D-A-K-TR) is optimized for automated pick-and-place assembly and high-volume production environments. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.
Frequently Asked Questions (FAQ)
Q: Are QSE-020-01-H-D-A-K and QSE-020-01-H-D-A-K-TR electrically and mechanically identical?
A: Yes. Both parts are functionally equivalent. They share identical connector specifications, including 40 positions, 0.031" pitch, gold contact finish, and surface mount configuration. The only difference is packaging format.
Q: What is the difference between tray and tape & reel packaging?
A: Tray packaging is used for manual handling and lower-volume assembly. Tape & reel packaging is designed for automated pick-and-place equipment and high-volume production. The component itself is unchanged.
Q: Can I use QSE-020-01-H-D-A-K-TR as a direct replacement for QSE-020-01-H-D-A-K?
A: Yes, provided your assembly process supports tape & reel format. The electrical and mechanical performance are identical.
Q: Are both parts ROHS3 compliant?
A: Yes. Both QSE-020-01-H-D-A-K and QSE-020-01-H-D-A-K-TR are ROHS3 compliant with MSL 1 rating.
Q: What are the mated stacking height options?
A: Both parts support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, allowing flexibility in connector stack configuration.
